Current repairs are carried out to ensure the efficiency and reliability of the equipment until the next planned repairs. At this type of repair, work should be carried out on the inspection of electrical equipment, cleaning, sealing, adjusting and repairing individual blocks and parts with the elimination of defects arising during operation.

As planned repair, great attention is necessary to pay for operational personnel with 3 group tolerances to electrical installations. When repairing an electric motor, you need to de-energize it and make sure that the electrical equipment is not under voltage. Visually inspect this engine, whether there are damage, chips and other defects leading to the failure of the engine. When disassembling the engine, we pay special attention to the integrity of bearings and lubrication. Bearing lubrication must be 75%, only in this case, you can use the engine

4. Types of repair, essence of them:

Maintenance - This is a planned repair in which the normal operation of electrical equipment is ensured by replacing or restoring worn items of equipment, purchased products, as well as by conducting preventive measures, regulating mechanisms, eliminate individual faults.

At the current repair of electrical machines, the following works are performed;

Check the degree of heating of the housing and bearings, uniformity of the air gap between the stator and the rotor, the absence of abnormal noise in the operation of the electric motor;

Cleaning and blowing the electric motor without disassembly, suspender of contact connections from terminal shields and connecting wires, stripping rings and collectors, regulation and fastening traverse of the brush holder, restoration of isolation in the output ends, electric brushes;

Shift and topping oil into bearings.

If necessary, produce:

Full disassembly of the electric motor with the elimination of damage to individual winding places without replacing it;

Flushing knots and parts of the electric motor;

Replacement of faulty groove wedges and insulating bushings, washing, impregnation and drying of the electric motor winding, coating the winding with a lacquer, checking the fan mount and its repair, the rod of the rotor shaft shaft and repair the cells (if necessary), shift flange gaskets;

Overhaul - This type of repair, an asynchronous engine with a KZ rotor in which the engine is completely disassembled, partially or comprehensively replaced its parts or nodes, check the repaired parts and the unit as a whole, completely replacing the stator windings, are taken under load. In front of the overhaul of the electrical equipment of the turning and rope machine 16V20, the statement of the maintenance of work is drawn up and a set of necessary spare parts, equipment, purchased products is prepared.

With major repairs, the following operations produce: full or partial replacement of the winding; Editing, rubbing the neck or replacement of the Rotor shaft; Rotor balancing; replacement fan and flanges; Complete propagation of the roosters; Cleaning, assembly and coloring of the electric motor and testing it under load.

5. The procedure for the output to the repair of electrical equipment:

When withdrawing to the repair of electrical equipment 16V20, it is necessary to carry out organizational and technical measures to organizational measures include: registration of the necessary documentation, the preparation of the application, the issuance of outfits, drawing up a defective statement, training personnel.

You must post posters and safety signs. Also install portable grounding if necessary, the fence of the workplace.

Watching prohibiting posters: on the drives of "drives of drives" of switching apparatuses with manual control, "switches, switches, automata" in order to avoid supplying voltage to the workplace, posters must be posted "Do not include! People" work. "Opening for fences. On the valves covering the access of air into pneumatic drives disconnectors, the poster is hung "Do not open! People work." Workplace fence, posting posters: In the electrical installations, the posters are grounded "grounded", with the erroneous inclusion of which the voltage can be fed to the grounded sector. For the temporary fencing of the current-carrying parts remaining under voltage, shields, screen, screens made of insulating materials can be used. Temporary fences should be applied "Stop! Voltage" or relevant posters. There are three forms of operation and repair of electrical equipment:

1) Centalized; 2) decentralized; 3) mixed. 1. The centralized is a form that can be applied at most industrial enterprises. With this form, the interremmer's maintenance and all types of electrical equipment are made united for the entire enterprise to the repair unit: a repair brigade, repair area or repair shop, which is part of the main energy service. Centralized form has a significant advantage over other forms of repair organization, as it allows to concentrate in the repair unit specialized, repair and testing equipment, specialized repair shots, reserve electrical equipment, spare parts and materials, repairing repair in accordance with advanced technology using high-speed Repair methods.

2. Decentralized - the form applies at enterprises having a simple electrical equipment that does not require specialized repair and test equipment for the repair. With this form, the service and repair personnel are part of the main workshop. The repair of electrical equipment is made at workplaces or repair shop located on the territory of the main workshop.

9. Control and test of EO, after repair:

Tests of electrical equipment should be carried out in compliance with the requirements of safety and PTE regulations.

Measuring the insulation characteristics of electrical equipment under the operating voltage is allowed to be carried out under the condition of the use of devices that ensure the safety of work and the protection of the normally grounded output of the controlled object from the occurrence of hazardous voltage on it when communicating with the Earth.

Before testing the insulation of electrical equipment, the outer surface of the insulation should be cleaned of dust and dirt, except when tests are carried out by a method that does not require the disconnection of electrical equipment.

The test of the insulation windings of rotating machines with an increased applied voltage of the frequency 50 Hz should be made alternately for each electrically independent chain or parallel branch (in the latter case, in the presence of complete insulation between branches).

The windings, interconnected by tightly and not having the branches of both ends of each phase or branch, should be tested relative to the body without separation.

The test voltage should rise smoothly at a speed allowing visual control over measuring instruments, and to achieve the established value to be maintained unchanged during the entire test time. After the desired shutter speed, the voltage is smoothly reduced to the value of no more than one third of the test and disconnected.

Under the duration of the test, the time of the application of the full test voltage set by the rules is implied.

10. The procedure for accepting electrical equipment after repair:

When accepting, you need to perform the following operations:

Visual inspection; Check the winding of the stator (for integrity, on the closure between the phases; on the closure of the windings on the body, on the viton closure.)

Assessment of the quality of the repair. When defects are detected, the repair is not considered to eliminate them and secondary check of electrical equipment under load over the next 24 hours.

The electric motor after repair is tested on the test stand in the workshop with the execution of an act of checking in form. After checking, with positive test results, the electric motors are transmitted to the technical workshop with the installation of the pump (other similar) forces of the repair service of the electric workshop in the presence of serviceable lifting mechanisms and free passages for the electric motor transportation. In the absence of load-lifting mechanisms or their malfunction over this electric motor, installing on the frame of the pump (other similar) unit, together with the technological service of the workshop, on the balance sheet of which this electric motor is located. The centering of the electric motor with the transmitted equipment is made by the repair service for the manufacturing workshop.

11. The use of modern instruments, tools and technology during operation and repair of EO:

As digital measuring instruments, we found wide use:

1) Ammeter - a device for measuring current force in amperes.

The scale of ammeters is graded in microam, milliamperes, amperes or kilos amperes in accordance with the measurement of the instrument.

Change

Sheet

KP 140448.14.4РЭ1.000 PZ.

In the electrical circuit, the ammeter is turned on sequentially with that section of the electrical circuit, the current strength in which is measured; To increase the measurement limit - equipped with a shunt (for constant and alternating circuits), current transformer (only for alternating current circuits) or magnetic amplifier (for DC circuits). A complete device from the current-measuring head and a transformer of a special design is called "current-dimensional mites".

2) Current testers - a device for measuring AC without breaking the chain in which the current is measured.

The principle of operation of current-dimensional ticks is based on the fact that the current flowing in the wire creates a magnetic field around itself. If this is a variable field, according to the law of electromagnetic induction in another conductor, covering the wire with a current, an EDC occurs, which under certain conditions is proportional to the measured current.

3) Voltmeter - the measuring device of the direct reference to determine the voltage or EDC in electrical circuits. It is connected parallel to the load or source of electrical energy.

4) Multimeter - a combined electrical measuring device that combines several functions. In the minimum set, this is a voltmeter, an ammeter and an ohmmeter. Sometimes a multimeter is performed in the form of

toco-measuring ticks. There are digital and analog multi meters.

The multimeter can be like a light portable device used for basic measurements and troubleshooting, as well as a complex stationary device with a variety of features.

A typical error of digital multimeters when measuring resistance, constant voltage and current less than ± (0.2% +1 units of junior discharge). When measuring alternating voltage and current in

Telfers are widely used in construction and industry for carrying out lifting and installation work. They are electrically driven devices that work from the engine and can lift loads weighing up to 10 tons to a certain height. Telfers are installed on single-grayscale bridge cranes or on a monorail path. The design of the equipment includes a movement mechanism, with which the horizontal movement of cargo is produced.

The installation of the Telfer should be carried out by a specialized organization or a qualified specialist who has a certain preparation. For proper installation of equipment, it is important to take into account the following conditions:

1. load capacity and telfer lifting height;
2. speed of mobile mechanism;
3. beam profile parameters;
4. terms of use of equipment;
5. compliance of the voltage of electricity with the requirements of the manufacturer;
6. compliance with the installation and connection to safety requirements.

Telfers are usually shipped assembled. Before installing, you need to make sure that the power supply voltage corresponds to the equipment parameters. Many types of professional equipment work from an industrial power supply, but there are also models for nutrition from a regular 220V network.

When choosing an equipment, you also need to pay attention to the beam profile numbers. In the passport of the equipment, it is indicated on the tracks of which size can be installed cartridge. It is not allowed to use the telfer on beams with a profile smaller than indicated in the passport.

Before installing, it is important to carefully inspect the equipment.

• It should not be dust, dirt and moisture, so the telpher needs to clean, dry and smear in accordance with the requirements of the manufacturer.
• It is necessary to check the health of all bolted, contact compounds and locking mechanisms.
• An experienced electrician should check the condition of the wires and measure the insulation resistance.

The telfer is installed on the track with bolts and fasteners, studs and a set of washers included in the equipment kit. The telfer must be installed so that the distance between the wheel of the cart and the rail is 4 mm on each side.

It must be traced that anything prevented the movement of the trolley. To do this, it is not recommended to paint the rail track, as the paint creates resistance. Lubrication track can also interfere with the trolley. In addition, the track should be regularly cleaned from dust and dirt, dried from moisture to avoid corrosion. The railway must be free, and the slope must be at least 3%. There are special security requirements that the railway must match. Below we give some of them.

• The distance from the telfer to the ceiling or to the lower point of another equipment operating above should be at least 100 mm.
• The distance from the Telfer to the walls of the building or to the columns and the rail is at least 60 mm.
• From the bottom of the telfer to the floor or to another working platform - at least 2000 mm.
• The distance from other equipment running next to the telfer is at least 400 mm.

Connecting Telfera

It works from the power supply, but before connecting it to the network, you need to pre-check.

• All separate parts of the telfer should be inspected for rust. If on the brake wheels, the engine cover and the brake cover will be rust, then after connecting the power, the engine can tan.
• You need to check the reliable connection of the electrical block. This uses an ammeter.
• It is also important to check the phases by supplying the voltage. You need to suspend the telpher and pressing the control buttons to check the direction of the hook and trolleys movements.

Electric telphers are connected to the power supply by a specific scheme specified in the equipment passport.

Important!

The network voltage must correspond to the Telfer parameters. When choosing a power cable, it should be borne in mind that voltage drops should not exceed 10%. The length and diameter of the cross section of the cable must coincide with the power of the telfer engine.

Safety requirements

Telfers should be operated by people who fully own all knowledge according to safety rules. In addition, specially designated people must regularly inspect the serviceability of the equipment.

Before the first exploitation, the telpher should be tested with loads weighing 25% higher than the nominal capacity. The test should last a maximum of 10 minutes.

Warning is prohibited to exceed the nominal capacity when working with the Telfers. In this case, all ropes, hooks must be appropriate. Failure to comply with the rules of security is dangerous to life near people and for the safety of cargo.

In the passport of the equipment should be indicated how many times you can use the telfer for an hour. You need to strictly follow this requirement to avoid engine overheating. When using the telfer, you can not leave the cargo in the suspended state. It is also not recommended to press multiple buttons simultaneously. After using the equipment, it needs to be disconnected from the power supply.

Inspection of equipment should be carried out at least once a month. During the inspection should be checked:

• the condition of all individual parts;
• reliability of fasteners;
• state of the rail track;
• brake work;
• the state of insulation of electrical wiring, etc.

The results of the check should be recorded in the inspection log. All detected faults are subject to immediate repair or replacement.

Requirements for service personnel

For controlling the electricity, certain responsible for this mechanism are assigned, and for maintenance and repair of them - locks and electricians. All of these individuals must undergo proper training in accordance with the "rules of the device and the safe operation of lifting cranes" and obtain a corresponding certificate. The results of certification and knowledge checks are issued by the protocol and are recorded in the knowledge verification log.

Working main professions to controlling the electricity from the floor or from the stationary console and hanging the cargo on the hook of electrotals are allowed after the appropriate briefing and checking skills in the order installed in the enterprise.

Re-checking knowledge of persons serving personnel (craners, electricians, locksters, plumbers) is carried out at least once every 12 months.

Workers of the main professions serving the hoists and the jokes of cargo to the hook should take re-instructing at least once every 12 months.

For the proper maintenance of lifting cranes, the owner is obliged to provide craners, locksters, electricians and landlords by instructions that determine their rights, duties and the procedure for the safe production of works, taking into account the type of electrotals, specific operating conditions, and maintenance and repair of electrical circulation and the requirements contained in the "Device and Safe Rules and Requirements operation of lifting cranes ".

Manufacture of work and safety

Workers, controlling Talut, must be from the side of the open part of the drum. Place of work should be well lit and have a free passage for service personnel.

The mechanisms of the hoists are included in the operation of the corresponding button on the push-button station, to stop the button is pressed.

Ropes, chains and other airproofing devices must be proper load capacity, have appropriate stigs and tags and fully respond to the requirements of the Gosgorthennadzor. Ropes and chains should be selected such a length so that the angle between the branches does not exceed 90 °, the increase in this angle can be allowed only in exceptional cases when the height of the hook lift does not allow to use longer chips and when it eliminates the possibility of moving chalks for cargo.

The cargo must be tied up so as not to slip with it racing adaptations. Charging ropes and chains should be superimposed without knots and loops; Under sharp ribs, it is necessary to put lining, protective ropes and chains from damage. Small cargoes need to be lifted and moved in specifically for this purpose.

The cargo moved in the horizontal direction must be raised by 0.5 m above the objects found on the way.

When moving, the hoists should eliminate the lunch of the cargo, when the hoist is stopped at the time when the cargo rope has a maximum deviation from the vertical, it is recommended to briefly turn on the tal so that its movement coincided with the direction of the departure direction.

For the reversal of long and bulky goods during their lifting or movement, special deficiations (hooks) of the corresponding length should be applied.

The moveable cargo is allowed to omit only to the place intended for this, where he could not fall, tip over or slip. The location of the cargo must be pre-laid appropriate lining strength so that the floating ropes or chains can be easily removed from under the cargo.

The cargo should fit on the platform and trolley and to be filmed from them without a malfunction.

When lifting the cargo, it must be pre-raised to a height of no more than 200-300 mm to verify the correctness of the trim and reliability of the brakes.

The performance of the pulse should be avoided (very often alternating inclusions), during operation it is necessary to monitor the health of both brakes that should work simultaneously. After completing or during a break in the operation, the electric power must be unloaded, the switch that feeds the tal must be disconnected and locked.

Do not:

• The surfaces on which the rollers are moving, roller rolling surfaces and a hints of the climb mechanism with the movement mechanisms to paint, as the paint interferes with a good clutch of rollers with a monorail road and increases the storage resistance of electrotal through the monorax.
• While working under load between cargo and wall of the house, column, machine, stack, etc.
• Raise a cargo whose weight exceeds the maximum lifting capacity of the hoist. When using electrotals for lifting and transporting molten metal, liquid slag The maximum weight of the cargo should not exceed 75% of the maximum load capacity and must be performed by the requirements of the rules of the device and the safe operation of load-lifting cranes.
• Exceed operation mode.
• At the same time, press the buttons that include opposite movements of the mechanisms, suddenly switch the mechanisms for the opposite.
• Use the end switches as working bodies to automatically stop the mechanisms, bring the tal to the terminal stops installed on the monorail.
• Using the tali foundations or cargoes, flooded land, approaching land, laid by other cargo or bolted strengthened; Release the floating ropes or chains hooked by cargo. Lift the cargo if the rope deviates from the vertical, lift loads suspended on the edge of the hook and in an unstable position, lift the goods in the container filled above the sides; Move the goods in those places where the cargo fall can cause an explosion, a fire or other dangerous consequences.
• Unwind weakened rope at Taly without a rod-layer when the suspension is at a lowered state; Align suspended or moving cargo weighing people.
• Operate the electric power with an open cabinet of electrical appliances.
• Installing end stops against rollers carts.
• Work with faulty limiters.

Maintenance

The frequency of inspections and the scope of work establishes the administration of the enterprise, based on the specific working conditions of the Tali. It is recommended to make inspections at least once a month and when conducting them must be checked:

• the state of the monorail path and tires;
• reliability of grounding;
• clean tali, presence and state of lubrication;
• the state of insulation of an electric vehicle according to the current standards of the safe operation of the mechanisms with an electric drive;
