Name: XB-type duct fabric compensator
Features:
1, the compensation inflation: can more than compensate for the direction, only a single type of compensation is much better than the metal compensator.
2, compensation installation error, due to pipeline connection, the system error is inevitable, better to eliminate fiber compensator Installation error.
3, the muffler vibration isolation: fabric, cotton itself with moisture absorption, vibration isolation, can effectively reduce the boiler, turbine and other system noise and vibration.
4, no reverse thrust: As the main material for the fabric, weak pass. Fiber compensator simplifies design, avoid using large bearings, save a lot of material and labor.
5, good high temperature corrosion resistance: the use of fluorine plastics, silicone materials, good heat and corrosion resistance.
6, sealing: a relatively complete production assembly systems, fiber compensator almost no leakage.
7, light weight, simple structure, easy installation and maintenance.
8, the price is lower than the metal compensator, the quality is better than imported products. Price of imported products 1/2-1/5. Compensator fabric duct installation requirements : 1, flange bolts should be tightened gradually uniform pressure, the screw bolt tightness as uniform as possible. Use of harsh conditions of the occasion, plus flat pad in addition to a weak spring washers can be added outside, to prevent the nut loose. 2, compensator and matching flat welding flange temperature should be between the first with the appropriate asbestos rubber gasket. 3, in the trial, should limit compensator screw to make appropriate adjustments to facilitate product elongation or compression. 4, pipe connections, should be the appropriate limit screw loose, to prevent the compensator plate bending or product limit deformation. 5, welding operations for cover rubber cover material (fabric) surface to prevent damage to welding slag products.
Duct fabric compensator range of applications:
1, boiler plant 2, 3 cement plants, steel mills, melting furnace, incinerator 4, 5 thermal power plants and nuclear power plants, air conditioning system 6, glass, mining, 7, 8 oil and chemical companies , empty the clean coal plant far as 9, 10 Blower, Aluminum and Carbon Plant
