Purpose and device TRC. Fuel dispensers of domestic production. What a kind of better

Each TRC, regardless of its common design, consists of:

The fuel pump driven by the electric motor;

Coarse purification filter installed on the suction pump nozzle;

A gas separator installed after the pump on the discharge line;

Devices for reducing consumption at the end of the dose issuing, which is usually set after the gas separator;

Volume meter for dose order;

A distribution sleeve with a valve, an indicator before handout or handout for controlling the quality of the fuel issued (the absence of air bubbles in the fuel) is checked;

A reading device associated with the volume meter to display information about the amount of fuel issued and the device leading the column.

Principal hydraulic scheme of operation TRC:

Designation:

1 - receiving valve; 2 - Counter with flow sensor; 3 - volume meter; 4 - solenoid valve; 5 - sleeve pressure; 6 - indicator; 7 - crane distribution; 8 - pumping monoblock; 9 - coarse filter; 10 - pump; 11 - Filter of fine cleaning; 12 - gas separator; 13 - Camera float.

On modern gas stations, a fuel leave system is used to control the TRC, which includes: a system block of a computer, display, keyboard and cash register. The fuel leave is set to the dose.

When removing the dispensing crane, an electric motor is automatically turned on. Under the action of the vacuum generated by the pump, the fuel from the tank through the receiving valve enters the pump. The pump serves fuel to the gas separator. Through the valve, I am a meter volume of the measured fuel comes through a distribution crane into the consumer tank. When fuel flow into the gas separator, the flow rate is sharply reduced due to an increase in the flow of fluid, as a result of which the fuel and air vapor is the most complete release of fuel vapor, both with a small and considerable scene.

The fuel from the gas separator enters the volume meter. Filling cylinders, fuel leads to the movement of pistons, which move from one extreme position and other. The progressive movement of the piston together with the scene, on which it is rigidly fixed, is converted into the rotational movement of the shaft, and in one course of the piston, the crankshaft and the spool turn 180 °. The rotation of the crankshaft with a spool makes it possible to fill alternately each of the four cylinders, simultaneously displaces the fuel from the opposite cylinder (two pistons are fixed on the same coolese). The rotational motion of the crankshaft of the volume meter is transmitted through the coupling onto the fuel consumption sensor shaft.

The pump receives a rotational movement through the clinorem transmission from the electric motor.

In order to reduce the hydraulic losses and reduce the size of the hydraulic column system, there is currently a tendency to combine a number of the hydraulic system nodes into one node (monoblock), in which the functions of the combined nodes are performed by separate monoblock cameras. As a rule, the pump, filters, a gas separator, a float chamber, a pump operation valve are combined in the monoblock. In this case, the volume meter and the electric motor are placed directly on the monoblock.

Fuel pumps of columns can be different designs. Rotary-lamellar type pumps received the greatest distribution.

Some foreign firms fuel dispensers apply multistage submersible pumps that are installed separately from the TRK inside the tanks with fuel on the suction lines of the columns. Such pumps can serve either one column or several. An example of such columns can serve as columns of Tokheim Corporations (USA) and Dresser Wayne (Sweden). Fuel pumps must have safety valves that provide a constant fuel pressure in the discharge line, and the watering line for fuel in case of incorporating the TRC when the fuel dispensing crane is closed.

Filters brutechochychydesigned to protect the hydraulic system of columns from entering outsided solid particles of large size (more than 80-100 μm), which can lead to wear, pump failure and volume meter.

The speakers also establishes a fine cleaning filter in order to issue fuel consumers cleaned to a certain degree (usually up to 20 microns). The filters use either grids or a variety of filter materials.

Gas separators The fuel discharge columns are designed to separate air fuel, which can fall into it when draining fuel in tanks, as well as into the suction pipe when operating the fuel pump column. In most cases, the air separation from the fuel in the gas separators occurs due to a sharp decrease in the fuel flow rate by passing through a sharply expanding pipeline. There are designs of gas separators for columns in which the gas separation is carried out by spinning the fuel flow in the pipeline along the screw line. In this case, the liquid fuel phase, as heavier, the centrifugal forces is pressed against the pipeline walls, and the gas phase moves along the central axis of the pipeline, is selected through a special hole and is removed from the pipeline. An example of such a gas separator can serve as gas separators of the company "Bennet" (USA).

The steam-air mixture of the gas separator usually enters a special assembly assembly called a float chamber, where there is some condensation of fuel vapor, the precipitation of the fuel particles carried out with the steam-air mixture and emissions of the isolated air and the vapor into the atmosphere. Liquid fuel deposited in the float chamber, as the camera filling the camera, raises a special float that opens a hole in the bottom of the camera I produce fuel into the suction piping of the column. At the end of the release of liquid fuel from the chamber, the hole is closed, and the operation of the float chamber continues.

Usually, after a gas separator in the hydraulic system of the fuel dispensers, a device is established to reduce the flow rate at the end of the dose issuing in order to complete the operating column at a small flow rate, which significantly improves the accuracy of the dose vacation. Single or double-acting solenoid valves are usually installed as such devices. Single-action valves only reduce fuel consumption at the end of the dose issuing. Double-acting valves in addition after the end of the dose is completely overlapped with a pipeline. Commands on the flow rate and full overlap of the valve pipeline gives a column control system, including or turning out the valve electromagnets. In existing speakers, the interval between the team to reduce the flow rate and the end of the dose of fuel is from 0.4 to 1 liter.

Volume meter Designed to measure the amount of output fuel. As a rule, the amount of fuel in the TRC is measured in units of volume. Separate manufacturers of fuel dispensers are made attempts to measure the amount of fuel issued in units of mass. But this does not yet find mass use in the fuel dispensers in connection with a significant complication of their design.

The method of measuring the amount of fuel in units of volume is the easiest, but it requires the introduction of amendments to a volume change in the amount of fuel depending on the temperature change. This is done by either structural elements in the column, or by recalculating with the help of special tables. The columns usually use compacted volume meters. This is basically the piston meters of volume in which the measuring elements are cylinders from which the fuel is pushed with pistons. The distribution of the flow of pistons is carried out with the help of special spools. The moving pistons rotate the crankshaft, with the end of which the reading device is connected, which gives digital information about the amount of fuel released.

Reporting devices There may be different designs: mechanical shooter, mechanical roller, electrical mechanical, electronic. They can only display information about the value of the dose issued or, in addition to this information, more information about the price of one liter of fuel and the value of the issued dose. All mechanical counting devices displays more information about the total amount of fuel issued by column since its installation on the gas station.

Curneyed mechanical type devices are installed on the output shaft of the volume meter, or have any mechanical connection with it. Curlons of electromechanical and electronic type devices are set independently of the volume meters. When using electromechanical and electronic checking devices, an additional node is introduced - the pulse sensor, which is installed on the output shaft of the volume meter and gives electrical pulses with an electronic wording device, translating each turnover of the output shaft in a strictly defined number of pulses. And since in one turnover of the volume meter, a strictly defined amount of fuel is issued (depending on the design - 0.5 liters or 1 L), then the reading device, depending on the amount of pulse received, displays information about the number of fuel released in liters. The same values \u200b\u200bin liters come to the remote control of the column. A column with electronic reading devices has a much greater possibility for automating technological processes on a gas station than columns with mechanical counting devices.

In the hydraulic column system, the indicator with a glass cap or a window, which can be observed after the flow of fuel coming out of the column, and control its gaspace, is installed in the hydraulic columns. When the air bubbles are found in the fuel indicator, the operating column must be discontinued, since this indicates a violation of the suction pipeline, due to which the large air seats occurs along with the fuel with which the column gas separator does not cope. Repair of the suction pipeline is required.

Disposal sleeves The columns are usually carried out with rubberbear. Recently, the sleeves from polymeric materials began to appear. The work of transfer sleeves is carried out in difficult conditions. Often their gears, twisting, exposure to petroleum products occur. Audges on them with wheels of filled cars are possible. Therefore, it is necessary to pay special attention to the quality of sleeves installed on the speakers.

At the weekend ends of handouts are installed distribution cranes. They can be automatic and non-automatic. Cranes have the outlet nozzles (nose), which they are inserted into the fuel tanks of the filled vehicles. The opening of the crane is carried out manually by pressing the special levers. Depending on the pressure force on the lever, the degree of opening of the crane is regulated. In automatic cranes when filling the fuel tank to the top level, when the fuel reaches the tap pipe, it is automatic closing.

All the basic components described above are combined in 2-3 blocks and are combined in one package of the TRK.

In order to ensure the possibility of issuing fuel of several varieties into two sides by one column, multi-screw columns (4, b, 8 and more sleeves) are used with independent hydraulic systems operating on their sleeves. Such columns represent single aggregates, allowing to reduce the area necessary to set the columns.

In addition to the above nodes, other additional nodes can be used in the columns, depending on the additional tasks performed by speakers. To solve the environmental problems, the columns are equipped with nodes to capture the vapors of petroleum products emitted from the Gorlovin of the fuel tanks of cars when fuel refueling them. These are special handouts having additional valves for the fence of pairs of petroleum products from the tank to the column, two-channel (coaxial) handouts, pumps for pumping vapors from the column to tanks, special valves that balance fuel and vapor expenditures, fire fuses, etc.

In accordance with the state building regulations of Ukraine, DBN 360-90 (Change No. 10) on the gas station located in the field of settlements, the columns equipped with a discontinuous clutch that prevents the leakage of fuel in the event of a separation of the hand-sleeve speaker, which may occur upon the departure of the automotive Tools from the place of refueling with a pistol undepended from the fuel tank.

TRC of domestic and imported production must have a certificate of approval of the type of measuring instruments and the number of the state registry of measuring instruments. Information about the certificate and the number of the State Registry is indicated by the manufacturer in the form (passport) column.
Fuel dispensing columns are means of measuring fuel volume and are subject to state verification: primary - when producing from production or after repair and periodic - during operation in the prescribed manner.
With the positive results of the state verification of the seal with the impression of the state belief in places in accordance with the sealing scheme given in the manufacturer's operational documentation.
When repairing or adjusting the TRK or MRK with the removal of the state belief seal, in the equipment repair journal, the date, time and reading of the total counter at the time of removal of the seal and on the completion of the repair and adjustment of the error of the TRC and the act of accounting for petroleum products is drawn up when performing repair work on the TRC (MRK).

TRK Operation, General

In order to prevent spills and straits on the gas station, a TRK should be used equipped with a dispensing crane with an automatic cessation of fuel issuing with full filling of the vehicle tank.
The sequence number of columns (or side of the speakers) is applied to the TRC), the brand of the petroleum product. In the necessary cases, the TRC should be inflicted or in other way information about the special conditions of the device or refueling vehicles. On TRK, designed to leave the eaten gasoline, the inscription should be applied: "gasoline ethyl. Poison".
Maintenance, repair, verification of the TRK, MRK must be recorded in the equipment repair log. In the formulars (passports), the TRK makes marks about the number of fuel released from the start of operation, repair and replace the units.
In the case of a technical malfunction, the lack of petroleum products or in other cases of the impossibility of the operation of the TRK (MRK) on it, the plate with the inscription "Repair", "Maintenance" or other content informing about its non-working condition is hosted. It is forbidden to twist the distribution hose around the case of a faulty TRC (MRK). A mechanical blocking is allowed to perform a mechanical blocking that excludes the extraction of the dispensing crane from the "socket" on the housing.

TRK Operation, General
No operation of the TRC and IRK:

With an error in excess of the type of measurement specified in the description of the type of measurement;
In the absence or with the disturbed dummy seals;
In the presence of fuel leaps due to the leakage of aggregates, nodes and compounds;
With technical malfunctions or retreats from the maintenance rules defined by the manufacturer and the rules for the technical operation of the gas station;
With violations of the column design described in the operational documentation.

TRC Maintenance, General

Types and frequency of maintenance

Maintenance of columns on the gas station can be divided into daily, prophylactic and seasonal.
Daily maintenance is carried out in need, but not less than once a day.
Preventive maintenance is carried out after pumping 200 lk fuel, but at least once a month;
Seasonal maintenance is held twice a year in order to prepare a column for exploitation in winter and summer conditions.
Scheduled maintenance is carried out according to the "system of maintenance and repair of equipment of gas stations" developed by CJSC NPP AZT

Fuel dispensers for gas stations are designed to leave gasoline, diesel fuel, lubricants and propane-butane mixtures in different containers. Also, the TRK is needed for accounting and measuring released products.

Types of fuel dispensers and the principle of their work

TRC - equipment that is presented in the market in two options is single and double. The selection depends on what gas station the device will be used. For mobile or container refills it is recommended to buy a single column. It serves only one car. Its main advantage is a low price.

On full-fledged gas stations, double fuel dispensers are installed. They serve two vehicles at the same time. This allows you to quickly fill cars and not create a queue. The minus is that the double TRC is more complex in maintenance and repair compared to single.

All fuel dispensers consist of such elements:

pump;
filters deep and fine cleaning;
pistol and Hose for distribution;
gas separator;
volume meter;
fuel meter;
countdown.

The principle of work is quite simple. First, the dose of fuel is indicated. Then the gun is removed for distribution and the electric motor is activated. This contributes to the movement of fuel from the storage tank to the pump, and from there - to the meter of volumes, which is connected to gear, providing a special shaft to create a signal of the indicator.

Fuel passes through the gas separation sensor and enters the gun. The next stage is the transformation of information about the amount passed. Data appears on the screen of the fuel dispenser.

Characteristics of fuel vapor speakers

The company "Vokso-SV" offers different types of equipment for refueling. The selection of the model is based on the throughput of gas stations, mobility, automation of processes and many other factors.

Fuel dispensing columns based on the requirements of them are classified according to such parameters:

type of drive. Three - manual, electrical and combined options. The first form is almost not used, since incompact in operation;
method of control. It can be manual mode, from a local or remotely specifying instrument. At the first embodiment, the fuel supply does not automatically stop. Local control implies that the client itself selects the required volume, and remote - the installation of the required value by the operator;
fuel consumption. Maximum value - 160 liters per minute;
method of placement. The elements of the TRK can be in one or more housings.

The cost of the fuel dispenser depends on all the above parameters. But the price is affected by the manufacturer.

Best manufacturers

In the online store you can buy a TRK of different famous brands. The best fuel dispensers:

"Topaz". Productivity - 50 or 140 liters. The manufacturer is domestic, so the cost is low;
"Shelf". The main advantage is an enlarged dispensing hose reversal;
Gilbarco. Comply with the most rigid safety requirements;
"Tatsuno Rus". The company is a manufacturer of benzo- and gas stations, which are used in small and stationary gas stations;
"Nara". Trademark over 50 years on the market and its entire products comply with international quality standards;
"Livenka". The main advantage is the life of the fuel dispenser at least 10 years.

This is not all trademarks that are presented on the site. If you do not know what kind of fuel disposable column for diesel fuel, gasoline or propane-butane mixture is needed, contact our managers.

We sell equipment for gas stations and tank farms for more than 20 years, so the quality of goods is no doubt. On the conditions of placement and delivery can be found in a special section.

Fuel dispenser (TRC) - the main part of any gas station. In the Russian Federation, it employs approximately 25,000 gas stations, on any of which is set at least two, and most often more than the TRC.

Each TRK daily sells fuel to dozens, or even hundreds of customers.

Despite the almost the same species, the columns have different principles of operation, which depends on the efficiency and ease of use.

Types of TRK

At the moment, when opening a gas station, 2 types of fuel columns can be installed:

- suction
- pressure

All modern TRC are equipped with an electronic control system that allows not only to activate the fuel supply remotely, from the operator's workplace, but also to track the refueling course on the computer and the display of the fuel and tube. Mechanical devices are currently practically not used.

Features of suction TRK

Systems of this species are significantly more popular - about 60% of all columns in the world work on this principle. The reason for this is not outstanding technical characteristics, but the fact that such models were invented and, as a result, began to be installed much earlier.

Their general principle of work is next. After requesting the driver, the cashier of the gas station from the panel sends a signal allowing the supply of fuel to the selected TRC. The feed itself is carried out immediately after lowering the fuel pistol into the tank and pressing the lever if manual guns are used.

At this moment, the electric pump installed in the body of the column itself and suction gasoline or DT from the storage tank begins. Due to the relatively low power of the pump, the tank is allowed to be placed no further than 45 m from the column. The fuel supplied is a series of filters, a gas separator and a volume meter, and then falls into the car tank.

As soon as the meter fixes the achievement of the volume installed by the operator, it will stop the operation of the pump and, accordingly, the supply of fuel.

Features of pressure fuel columns

The pressure systems appeared only about 50 years ago in the United States and gradually began spreading around the world. Now they still cannot be considered the most popular, but gradually install everything on a greater number of gas stations.

The key difference in the design is the location of the pump. In this case, this submersible device, which is installed almost at the bottom of the fuel reservoir. The submersible pump is more powerful, so it allows you to feed gasoline or DT immediately into several columns, and the tank is allowed to have a significantly larger distance - to 150 m.

When the pump engine is activated, the fuel passes through it and is sent to the intermediate node, where using the valve system is distributed between several columns to which the feed must be carried out. If the required amount of fuel is returned to the valve TRC, the oil products remaining in the pipeline fall back to the tank.

What kind of better?

Despite the smaller distribution, it is the pressure TRK in operation that are more efficient, economical and even convenient for customers.

Their only drawback is that when the pump malfunction on the gas station, the sale of a certain brand fuel is completely stopped, as it simply cannot be fed to fuel columns. However, the benefits of such a solution are significantly more.

With approximately the same costs for installing pressure TRC:

consume less electricity, as instead of a series of pumps, only one for each type of products works;
have a longer period of smooth operation - it is about 300-500 million liters, suction pumps fail after 10-12 million;
do not lose power over the entire period of operation, thereby ensuring faster customer service;
there are no problems of air traffic jams arising on most suction columns in hot weather;
due to the larger removal of tanks provide greater safety;
no noise when working, thereby provide greater comfort for customers
