Pulse damper

Abstract

The ininvention discloses a pulse damper. The pulse damper comprises a pulse damping ball; a non-deformation side of the pulse damping ball is placed on a damping ball support, and a deformation side of the pulse damping ball is attached to a buffer plunger; a pressure-bearing medium area is formed between the buffer plunger and the inner side of a pressure-bearing shell through tight fit; a limiting baffle is arranged at the upper end of the buffer plunger; the limiting baffle and limiting columns on the outer sides of the pressure-bearing shell work together; and the pressure-bearing shell is provided with a channel connected to a pressure transmitter indicator to reflect the pressure change condition of buffer mediums in real time. The pulse damper has the advantages that firstly, the problem that a buffer part of an existing damper directly makes contact with buffer mediums can be solved; secondly, the problem that part of the deformation quantity of the buffer stored energy is unable to be indicated can be solved; thirdly, the problem that special tools are needed for specialized operation of secondary air inflation when a common buffer replaces a diaphragm can be solved; fourthly, the problems that the deformation quantity of a common damper is too large and the diaphragm is prone to get damaged due to the fact that the system pressure suddenly increases or energy storage gas leaks can be solved; and fifthly, the alarm function is added so that an operator can be reminded to check the pulse damper in time.

Description

technical field [0001] The invention relates to the technical field of smooth impact of a liquid system with pulse impact and water hammer phenomenon, in particular to a pulse damper. Background technique [0002] Conventionally, for the shock smoothing treatment of the liquid system with pulse shock and water hammer phenomenon, the air chamber type pulse damper and the diaphragm type pulse charge damper are generally selected. The air chamber type pulse damper uses the inside of the pressure chamber to seal the air. The pressure chamber is connected to the liquid system. The air directly contacts the liquid medium. The pressure of the gas sealed inside is the same as the atmospheric pressure, so its energy storage effect is poor. The pulse shock smoothing ability in the system is weak, and it can only be applied to the low pressure system. And because the air is in direct contact with the liquid medium, the air will be dissolved and taken away by the liquid medium during t...

Problems solved by technology

[0003] In order to solve the above-mentioned problems in the prior art, the object of the present invention is to provide a pulsation damper, which solves the problem that the existing air chamber-type pulsation damper and diaphragm-type pulsation damper cannot avoid the contact between the buffer energy storage gas and the system medium It also solves the problem that the damper needs to be inflated twice due to the rupture of the diaphragm during use, which reduces the requirements for the professional operation of the special tool box; the added damping alarm function solves the problem that the operator cannot work on the damper. The problem of judging normal and abnormal conditions has realized the problem of monitoring the working state of the damper under high-demand conditions
