Damping compensator

Abstract

The invention discloses a damping compensator which is arranged on the inlet and outlet of a pump, and comprises an S-shaped corrugated pipe and connecting flanges which are movably sheathed on the straight sections of the two ends of the corrugated pipe; the wave trough of the corrugated pipe is provided with a rubber ring the cross section of which is in a tadpole shape; the connecting flange is in a hollow out structure; the straight section is welded with a V-shaped groove pad to be used as a connection seal element; the S-shaped corrugated pipe is adopted in the damping compensator; and a high-quality rubber ring is inlaid between the wave troughs, thus satisfying the requirements of damping, and preventing the extrusion deformation caused by the too-large deformation of the corrugated pipe; the V-shaped groove pad ensures the sealing quality and simultaneously reduces the energy transmission, thus enhancing the damping effect; and the connecting flange is in a hollow out structure, has the characteristics of simple structure, light weight, saved cost and good damping effect, and is easy to popularize and use.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to a shock absorbing compensator installed at the outlet of a pump for absorbing shock and noise. Background technique [0002] As we all know, installing a shock absorber at the inlet and outlet of the pump can reduce the vibration and noise of the pipeline system. At present, the traditional pump inlet and outlet shock absorbers generally use stainless steel corrugated compensators or rubber compensators. The axial direction of the stainless steel corrugated compensators The cross-section is corrugated and has a certain deflection, which can absorb vibration, reduce noise, and withstand high pressure and temperature. However, because the material of the bellows is made of metal, its shock absorption and noise reduction effect is not as good as that of the rubber compensator, and the rubber compensator There are fatal defects such as unhygienic, easy to age, delamination and tearing, and...

[0002] As we all know, installing a shock absorber at the inlet and outlet of the pump can reduce the vibration and noise of the pipeline system. At present, the traditional pump inlet and outlet shock absorbers generally use stainless steel corrugated compensators or rubber compensators. The axial direction of the stainless steel corrugated compensators The cross-section is corrugated and has a certain deflection, which can absorb vibration, reduce noise, and withstand high pressure and temperature. However, because the material of the bellows is made of metal, its shock absorption and noise reduction effect is not as good as that of the rubber compensator, and the rubber compensator There are fatal defects such as unhygienic, easy to age, delamination and tearing, and poor high-pressure resistance. Therefore, the market for rubber compensators has been shrinking in recent years, and it is not easy to be widely promoted.
