How to solve the problem of extremely high temperature in the air valve of a reciprocating vacuum pump?
Thread Content
For vacuum evacuation under reduced pressure, a combination of Roots and reciprocating vacuum pumps is used: ZJ1200 – ZJ600 – W300 – W5-1. At present, the temperature of the valve in the W5-1 vacuum pump is around 130 degrees; after operating for some time, the valve elements and springs get damaged. Is there any good solution to this problem?
There are usually several reasons for high temperatures in the valve: 1. Poor sealing, resulting in air leakage; 2. Overloading; 3. Problems with the valve itself, such as deformation of the valve elements, excessive or insufficient spring force, or broken springs. If the valve elements and springs in your unit break frequently, it is recommended to try using valves from another manufacturer, and also check whether the compressor meets the required specifications.
If the cooling system is functioning properly, a high temperature of the valve is likely caused by a poor seal.
That is because: 1> The intake and exhaust valves of the vacuum pump do not close properly, 2> There isn’t enough circulating water in the pump, and the water pipes may be severely scaled, 3> The pump’s seals are leaking air.:handshake
