Solve the problem of insufficient displacement of constant temperature and humidity test chamber

Solve the problem of insufficient displacement of constant temperature and humidity test chamber:

1. The common faults of the suction valve and automatic exhaust valve of the refrigeration compressor in the constant temperature and humidity test chamber are harmful to the exhaust volume. Metal material fragments or other dirt fall between the high-pressure gate valve of the air valve and the pump housing, leading to incomplete shutdown and steam leakage; This not only damages the displacement, but also damages the variation of working pressure and temperature between stages. Such problems can be caused by quality problems of the product to be manufactured, such as expansion and contraction of pump housing, steam leakage caused by severe damage to high pressure gate valves and pump housing.

2. Common faults of air inlet filter element: scale blockage, reduction of displacement; The breathing tube is too long and the pipe diameter is very small, which leads to the expansion of respiratory friction resistance and endangers the gas supply, so people should clean the filter element on time;

3. The yellow force of the valve does not match well with the steam force; If the elasticity is weak, the pump housing will not close immediately, while if the elasticity is too strong, the pump housing will slowly open, which will not only endanger the air supply, but also the increase in output power, the service life of the valve pump housing and changes in air pressure and temperature.

4 stuffing box closed is not tight, resulting in steam leakage, reduce air supply; The first reason is that the stuffing box itself does not meet the requirements when it is manufactured. Secondly, because the installation process, the hydraulic cylinder and stuffing box management center is not in place, resulting in damage, contusion, steam leakage. Normally, the stuffing box is filled with grease and has the function of wetting, sealing and water cooling.
