Where the vibrocomponentials are used. Vibrocomponents. Technical data of rubber flange compensator

Workspace:from -10 to 105 ° C.

Operating pressure:8-10 bar. For some models allowed short-term overpressure cold water up to 1.5 MPa.

Requirements for mounting

The vibrocomponator can be installed in any position. Installation locations must be selected taking into account the operating conditions of the pipeline system (space space, the values \u200b\u200bof the amplitude of displacements, etc.) and maximum deformations of compensators.

When conducting mounting work Screening, compression, bending or stretching the flexible element is not allowed. Pre-compression should not be more than 5 mm.

During installation under the pipeline, supports must be installed in close proximity to the compensator. Maximum distance between supports and flexible insert It should not exceed the three diameters of the pipeline.

Before assessing the vibrocomponancetor, it is necessary to check that the surfaces in contact with the joint have been carefully cleaned and did not have sharp edges that could damage the surface of the joint.

Pads between the compensator and the piping flanges are prohibited, the use of lubricant is also not allowed, as this can lead to the exhausting of the rubber flap of the compensator from the connection.

Tightening bolts should be performed crosswise. Bolts. flange connections It is necessary to install heads towards the flexible element to prevent damage to the compensator.

When performing welding work, the vibrocompanator must be dismantled or reliably protected from the molten metal spray from entering it.

Flexible inserts (vibrocomponentials) share pipeline communications to functional sections. This is done for many reasons; Extension of the service life of laid pipes and connected equipment is one of the main. The vibrator components consist of metal connecting terminals and, actually, the body of the vibrations: the bellows steel jumper or rubber in the form of a corrugated cylinder or sphere (several spheres) with cord amplification and multilayer reinforcement in the middle.

Types of viberocompensators

Flexible inserts are divided by a compensating jumper material: stainless steel, heat supply steel, rubber (EPDM); And by type of compound: Rubber - couplings (threaded) and flange, indefinite - under welding. Flexible inserts differ in type working design and a method of passive compensation; Industry produces more than ten options.

Application area

The main functions of the vibrator compressors:

compensation of inconsistency and thermal deformations of pipelines;
reduction of mechanical stresses;
reducing vibration during equipment operation;
reduction of noise;
protection against hydroudar;
electroplating (rubber).

Selection of flexible inserts for pipelines

Select the vibrarocomponscients should be taken into account diameter and form of pipeline terminations. It is important to take into account chemical composition The material transported by pipes. To work with chemically aggressive mixtures it is necessary to install special flexible inserts. Of great importance is the difference of temperatures inside and outside the pipeline; It is also taken into account when choosing a vibrarchair.

Characteristics of the vibratorisators

Flexible inserts withstand strong internal pressure and retain tightness with axial displacement. Central element Of the reinforced wear-resistant rubber, it is designed for operation at a temperature of up to one hundred and twenty degrees. Steel bellows jumper from heat-resistant steel can withstand elevated temperatures and large internal pressure drops. The working resource of the vibrator detector depends on the proximity of the installation with the active equipment, creating vibration oscillations, on the method of laying the pipeline, from soil drawdown and shifting the soil horizons.

Features of flexible inserts for pipelines

The vibrator "" Save "" pipeline with transverse-longitudinal displacements, taking the resulting shifts. If the displacement turns out to be critical, then the flexible insert serves as a fuse; The replacement of the outstanding compensator will cost cheaper search for the breakdown site on the pipeline and its repair. The vibrocomponentials are shy noise, vibrations and reduce hydraulic blows.

Application of vibrarocomptors

Flexible inserts are installed at the joints of pipeline sections in the chemical, mining, processing industry, in heat grid, on trunk water pipes. Through them are connected pipes and active equipment. Application of the vibrationactors next to pump modules Significantly extends the service life of technical units.

Installation and installation of flexible inserts

To install the vibrate letters used hand tool, levers, keys, solid and adjustable sets. Welded elements are connected by autogen or electric arc welding. When installing overall inserts, various supporting and lifting mechanisms, jacks, cranes, winches.

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.
Warranty obligations.
The warranty period in compliance with the consumer of transportation, storage, installation and operation rules is set 12 months from the date of commissioning, but not more than 18 months from the date of sale. All issues related to warranty liabilities provide a seller enterprise.

To the ommpentials used to eliminate vibrations on pumping equipmentis placed on the distance from pump nozzles in the range from 1 to 1.5 nominee diameters of the compensator. In some casesthe installation of the rubber compensator is lowered directly to the pump nozzle (If the manufacturer of the product, in the technical documentation allows such installation). The work of the compensator with closed or partially closed valve is invalid.
Before the beginning of the work on the installation of the product,the vibrocomponator must be checked making sure hissurfaces in contact with the joint are thoroughly cleaned and do not have sharp edges that could damage the surface of the joint. When conducting installation works, twisting, compression, bend, either stretching the flexible product element. Previous compression should not be more than 5 mm.
During installation, the pipeline must be fixed in special Support oh, locatedimmediately proximity to compensator. The ashism between the supports and the flexible insert should not exceed the three diameters of the pipeline.
Pasters between compensator and pipeline flanges are prohibited since the design of the product already has a protruding part of the elastic element providing a hermetic connection. T.applying lubricant is not allowed, as it can adversely affect the properties of the materials of the product andlead to tighten the rubber flanging compensator from the connection.
Tightening bolts should be performed crosswise. Bolt holes must be accurately combined with the corresponding holes of the response flanges. Compensators are equipped with rotating steel flanges, which simplify the installation and reduce the risk of damage to the elastic element in a consequence of the occurrence of twisting deformation. If the nuts are strongly tightened, the sealing surface may be damaged, leading to the deformation, as a result, to the wrong product of the product. Flange connections must be installed In the direction of the flexible element, the Iki is installed on the side opposite to the elastic elements to prevent damage to the compensator. If this is not possible because of various reasons, the threaded part of the bolt should not perform more than 2-3 mm to prevent the bellows of the bellows.

Do not carry out no pressure tests or system leak proper Installation Fixed points guide supports, connections, devices and other system elements. The presence of sudden pressure drops in the system exceeding the calculated parameters are not allowed. In the performance of welding works, the flange vibrator must be dismantled or reliably protected from the molten metal spray from entering it. and is at a sufficient distance from the place of work, since the effect of increased temperature can damage the elastic element of the compensator.
