Causes of valve seal failure
Classification:
Release Time：2017-10-26
Cause the valve seal failure mainly has the following several aspects: 1, natural failure because the seal is always in the medium, the sealing element to reach the service life of the valve seal failure. 2. Large fluctuation of pump inlet pressure may cause seal damage. When the pump inlet pressure is too small, the pressure in the pump cavity suddenly decreases, and the liquid in the sealing cavity returns to the pump cavity, resulting in dry friction of the sealing surface. The huge heat generated by the sealing surface in a short time cannot be taken away, thus causing the sealing surface to burn down and the seal to fail. When the pump inlet pressure is too high, the valve seal fails. 3. The seal failure caused by insufficient seal flushing mainly blocks the sealing cavity medium by forming a liquid film on the sealing surface. The function of the sealing flushing fluid is mainly to take away the heat on the sealing surface. When the sealing flushing fluid is insufficient or there is huge heat in the sealing cavity, which leads to the burning of the sealing surface and the failure of the seal. Pump chamber medium cut-off, seal chamber pressure suddenly reduced, seal effect ring sudden damage may cause seal flushing insufficiency. 4. Seal failure caused by bearing damage The position of the rolling body has changed after bearing damage, and the vibration of the pump has increased, resulting in valve seal failure.

The main causes of valve seal failure are as follows:
1. Natural failure
Since the seal is always in the medium, the valve seal fails after the sealing element reaches the service life.
2. Large fluctuation of pump inlet pressure may cause seal damage
When the pump inlet pressure is too small, the pressure in the pump cavity suddenly decreases, and the liquid in the sealing cavity flows back to the pump cavity, resulting in dry friction of the sealing surface. The huge heat generated by the sealing surface in a short time cannot be taken away, thus causing the sealing surface to burn and seal failure. When the pump inlet pressure is too high, the valve seal fails when the pressure in the sealing cavity rises and exceeds the limit that the seal can bear.
3. Seal failure caused by insufficient seal flushing
Sealing mainly through the sealing surface to form a liquid film on the sealing cavity medium to play a barrier role, the role of the sealing flushing fluid is mainly to take away the heat at the sealing surface, when the sealing flushing fluid is not sufficient or there is a huge heat in the sealing cavity, resulting in the sealing surface burned, sealing failure. Pump chamber medium cut-off, seal chamber pressure suddenly reduced, seal effect ring sudden damage may cause seal flushing insufficiency.
4. Seal failure caused by bearing damage
Bearing damage caused by the position of the rolling body has changed, the vibration of the pump increased, resulting in valve seal failure.
