Vibrating inserts for pumps. Rubber compensator. Vibrating inserts VS series

Vibrocomponentials (vibration) refer to the auxiliary pipe fittings. The main purpose is to absorb the vibrations created by other equipment in the system: pumps, compressors. Also apply to compensate for thermal expansion of pipes and side, angular displacement within values, permissible design a specific rubber compensator (depending on the diameter - up to 22 mm side and 45 ° corner displacement). Help to reduce the noise from the work of equipment that creates vibration, protect against hydrowards. Their work is significantly prolonged by the service life of the pipeline system, so in obligatory Installed after equipment that creates vibration. The transverse and longitudinal displacement and stretching of the plots of highways. Installed next to the equipment creating large vibrations.

The need to use vibration when connecting units to the pipeline is due to safety measures to prevent factors of destructive various elements networks or leading noise levels and for purposes electroplating piping and equipment protection from devastating mechanical exposure. In addition, the use of such devices is necessary in seismic areas and at the risk of soil movements on which equipment is installed, provided that the displacement does not exceed the permissible values \u200b\u200b(at higher loads it is more expedient to use special devices based on bellows compensators). SNIPA 14.15 requirements say: "On inputs to measuring devices, as well as in the fields of joining pipelines to pumps and tanks, it is necessary to provide flexible compounds that allow corner and longitudinal movements of the ends of the pipelines." Flexible inserts for pumps should be installed when operating pumps with over-11kW electric motors (less power electric motors can also cause unwanted noise and vibration).
Rotation of engine and pump rotors, as well as the conducted medium in the pipeline cause noise and vibration. The degree of impact on the equipment and the surrounding space depends on how correctly the calculations and in which state are the remaining elements of the system. The most effective way to damage vibration and reduce noise level is the use of vibration on foundation Plate Units and connecting nozzles to pipeline through rubber vibration. This allows you to maintain stable pump operation, reduce the load on fragile cast iron elements of the structure, as well as minimize vibration and noise. In addition, the installation of compressors and pumps for vibrationoporas without the use of rubber inserts on suction and pressure pipes leads to the russis of equipment on the flanges and as a result of the destruction of the housing of the aggregates and fastening of the pipeline. Vibra watches for pumps allow you to protect the equipment and pipeline from vibration, as well as prevent the resonance of the system.
Depending on the material of the flow part, the vibrating pressure for the pump can be used in the systems of transporting hot and cold water, air, acid media with a concentration of less than 10%, organic and inorganic alcohols, solutions of salts and alkalis, as well as bulk products. The permissible nominal pressure can be from 1.0 to 1.6 MPa, and the operating temperature from -40c to + 90 / 110c (depending on the model).
The price of products remains sufficiently low, due to timely supply and maintenance in the warehouse in the presence of the most popular sizes.

Vibrating station flexible rubber is a simple and reliable design consisting of elastic flowing part and metal connecting elements. The elastic part is made of heat-resistant rubber, reinforced with nylon threads and steel wire. Material has sufficient resistance to ultraviolet and atmospheric influences, as well as weak resistance to petroleum products. Flanges are made of steel with galvanic coating. Due to the design features, metal parts are not in contact with the conducted medium, which allows you to install products to pipelines and pumps of any types transporting permissible media.
Anti-Vibration Insert is the conditional name of the standard rubber compensator. And although the product is initially intended to compensate for deformations arising in the pipeline (compensation of lateral, axial and angular displacements), the ability to compensate for transverse displacements and wear resistance at frequent responses, makes them most affordable tool To reduce dynamic loads in the system. These products are significantly cheaper than complex anti-vibration structures made entirely of metal, which allows the use of compensators as rubber vibration. Successful application experience, served to the widespread dissemination of this decision. Such a compensator - the vibration station allowed to reduce the transmission of mechanical vibrations, noise level, oscillation, vibration in pipeline systems, while compensating for thermal lengthening of the system within allowable deformations. The use of the product allows you to galvanically unleash the pipeline and protect the equipment from the devastating mechanical exposure, practically isolating vibration.
Depending on the types of materials used in the manufacture of materials, the flexible vibration can be used when transporting hot and cold water, air, acidic media with a concentration of less than 10%, organic and inorganic alcohols, solutions of salts and alkalis, as well as bulk products. For the transportation of hydrocarbons, the product is unsuitable. The permissible nominal pressure can be from 1.0 to 1.6 MPa, and the operating temperature from -40c to + 90 / 110c (depending on the model), which allows them to be used in housing and communal services, petrochemical, gas, food and other industries.
The price of such products as a vibrating station remains low enough thankstimely supply and maintaining in the warehouse in the presence of the most sought-after sizes.

The temperature differences caused by the seasonal change of climate or the change in the characteristics of the transported medium, as well as the dynamic loads created by the working equipment, can cause the pipeline offset relative to its initial position. Even if it is relatively small, regular loads significantly increase the risk of damage to pipe fittings, supports and other highways. Exclude negative impact In this case, allows the use of a vibration, or a viberompensor.

What is a vibrating station and where it applies:

Vibrating, or flexible insert, is a type of industrial pipeline fittings designed to compensate for side, angular and axial displacements of the pipeline. It consists of an elastic middle part, made predominantly made of reinforced heat-resistant rubber or similar to it of an elastic polymer, as well as two connecting metal (most often steel) elements. The latter can be presented in the form of a threaded shank or flange - it depends primarily from the diameter of the pipeline for which the product is intended.

In high-quality vibrations, the elastic element has a multilayer structure. The inner layer does not have seams and is manufactured mainly from materials that allow us to use in systems with clean water. Further, a reinforcing layer of the synthetic tissue impregnated with a rubber (nylon), and one more rubber layer is applied on top of it, providing resistance to ultraviolet and ozone. As for the connecting parts, they are coated with an anti-corrosion layer, which provides protection against external influences. With the medium flanges and couplings are not in contact.

Flexible insert is mounted on pipelines, which are most susceptible to spatial displacements and vibrations, for example, located near compressors, pumps and other technological equipment. Most often, the above-mentioned aggregates are on special supports compensating for vibration, but it is transmitted to the highway. Also, the installation of the vibration is justified when it is necessary to ensure the possibility of a minor bias of the pipeline due to temperature effects or direction changes. But to use the vibration to correct errors made by mounting the line, is not allowed - in the original position they should not be loaded. Certain constraints exist for transported media.

Standard vibrocomponentials are permissible to mount on pipelines intended for transportation:

cold water;
hot water with a temperature not higher than 100º C;
non-concentrated (up to 10%) acids;
organic and inorganic alcohols;
solutions of salts and alkalis.

The use of them in the transportation systems of petroleum products, very hot and aggressive environments is unacceptable. First of all, it is associated with low resistance to them elastic central part. For the same reason, it is impossible to use this reinforcement on highways passing in rooms, the conditions in which can destroy the outer layer of the insertion. In such cases, blasting applies special purposeResistant to these environments (if they exist) or more expensive metallic vibrarocompons.

Choosing a vibrator compressor and installation features:

When choosing a vibrator compressor for a particular object or section, you must first take into account the following points:

type and temperature of the transported medium;
the nature of the loads rendered (compensated deviations);
pipeline diameter;
possible mechanical and chemical external impacts on fittings.

Some of the above factors can affect not only the species of the product used, but also on the features of the installation of the vibration. In particular, in some cases it is advisable to apply the possibility of its deformation of the elements: restrictive rings, control rods or special thrust.

In order for the vibratory insert to not only work effectively, but also served during the estimated period, it is necessary to strictly comply with all the requirements relating to their installation. In particular, on the one hand from flexible insert A moving or moving support must be installed, and on the other - fixed. You should also avoid contact with a flexible part of the inserting bolts, studs and other fasteners, and the nuts are plans from the outdoor side of the flange. To install the vibrator components, it is preferable to use collar flanges, or thoroughly clean the welding seams of flat, in order to avoid damage to the elastomer sector in the connecting element when tie.

Installation instructions and installation of a flexible insert Abra-EJF-10 - rubber anti-vibration compensator

Mandatory to fulfill ""
It is necessary to strictly follow the parameters specified in the tables above, reasonably apply control rods.
!!! When installing rubber compensators of Abra in the pipeline system, additional seals are prohibited in the form of elastic interflabsey gaskets, a reliable hermetic compound is provided by the rubber protrusion of the Abra vibrocompressor itself.
Flexible inserts should be installed directly behind the fixed support. A flexible insertion should provide movable supports.

It is preferable to use the collar flanges, although in the presence of the necessary qualification of the installers and the installation of flexible Abra inserts is possible and between flat flanges. Do not forget at the same time to clean the inner welds from the burrs in order to avoid damage to rubber.
It is unwanted to install the viberompensor closer than 1.5 diameters of the pipeline from the suspending devices.
The maximum allowable tightening moments of bolts for flexible inserts (vibrarocomponnets) of any manufacturers must be monitored by applying dynamometric keys. In particular, for ABRA inserts to DU80, the maximum torque is 60 N * M, and for large doors is 80 N * m.
Flexible vibrator inserts can be mounted in any spatial position.
It is not allowed to use a compensator as a reference structure, that is, the installation of the compensator must be performed after fixing the pipelines. Pipelines with both ends of flexible inserts must be fixed in fixed supports quite close enough so that the operating range of pipe offset is out of the limits allowed to insert.
It is not recommended that the preliminary compression of the compensator for installation exceeds 3 - 5 mm. Stretching inserts during installation is unacceptable.
It is not allowed twisting a flexible element of the compensator when installing.
Before starting the installation, it is necessary to centen the substantive and reducing pipelines by fixing them at a distance of no more than three diameters of the pipeline from the compensator.
Neither the anti-virus compensator nor the control rods are intended to compensate for the error in the installation of the pipeline, such as the shift in the center of the flanges.
Damage to the compensator is not allowed sharp edges Pipes or surface of the connecting flange.
The contact of the bolts, nuts or spills with rubber is not allowed (for example, when connecting a bolt nut - nuts are installed on the side of the opposite rubber elements - on the side of the pipeline).
The simultaneous work of the compensator for stretching and shift is not allowed.
The insertion of the insertion is not allowed when installing at the entrance of the pump or when working under vacuum (negative instrument pressure).
Welding work is not allowed in close proximity to the compensator insert without its protection or dismantling.
It is not allowed to stain in the flexible element of the compensator insert or the coating of its insulation layer
Storing compensator inserts is carried out in an unloaded state in a dry cool place.
Storage and transportation should be carried out without shock loads at temperatures: -40 ... + 65 ° C.
The estimated life of rubber compensators is 3 years.
