In the above, we also talked about how to deal with the constant temperature and humidity test chamber when the exhaust volume is not enough, but it is not useful to tell the complete, let's talk about the problem.
1. The influence of the failure of the suction and exhaust valves of the compressor on the displacement. Metal fragments or other debris are dropped between the valve seat and the valve plate, resulting in poor closure and leakage. This not only affects the amount of exhaust, but also affects the change in inter-stage pressure and temperature. This problem may arise due to manufacturing quality problems such as valve warpage, and second, due to serious wear of the valve seat and valve disc. And a leak is formed.
2, the constant temperature and humidity test box packing letter is not strict, resulting in air leakage to reduce the gas volume. The reason is firstly that the stuffing box itself is not required to be manufactured; the second reason may be that the piston rod and the stuffing box center are not well aligned during installation, causing air leakage due to wear and strain; generally, lubricating oil is added to the stuffing box. It can function as lubrication, sealing and cooling.
The cylinder, piston and piston ring of the constant temperature and humidity test chamber are seriously worn and out of tolerance, which increases the relevant clearance and increases the leakage, which affects the displacement. In the case of normal wear and tear, it is necessary to replace the wearing parts in time. If the installation is not correct and the gap is not suitable properly, it should be corrected according to the drawings. Through the above, I believe that everyone knows how to solve the problem of insufficient exhaust volume. If you want to know more clearly, please come to our company for inspection.
