Reciprocating compressor
Thread Content
In reciprocating compressors that operate in a cyclic manner, due to the high pressures they are subjected to – around 250 kilograms – along with a pressure difference of six to seven kilograms, could it be that the flow rate cannot be increased because of leaks in the check valves? What other phenomena?
What is the medium compressed by the rotary compressor, what is its flow rate, what is the inlet pressure, and what are the required outlet pressure values? Only in this way can the appropriate compressor model be determined~~
It should be suitable, as it was able to maintain a certain flow rate in the past; lately, however, the flow rate has decreased by almost one-third. What I want to know is whether this reduction in flow rate could be caused by leakage in the check valves for inflow and outflow. If that’s possible, what are the signs of such leakage?
A leaky check valve can cause high exhaust temperatures.
Have there been any operations to switch compressors or reduce load recently? If any exist, it’s possible that some unloading devices are not doing any work. We have encountered this situation before
No, we only have one unit; it’s not possible to switch. The load hardly changes; it remains around one hundred.
Reply to 4# suihaiming: I’m sorry, but why does the leakage of a check valve cause the exhaust temperature to rise?
Are you a fatty alcohol factory? Is it compressed hydrogen?
Internal leakage in a check valve affects the flow rate, as leakage from either the outlet valve or the inlet valve causes some of the gas to be expelled and then drawn back in, without entering the system. The compressor does some unnecessary work.
Does a check valve refer to the one located at the compressor’s exhaust port? Is there a large pressure difference before and after the check valve? If the difference is large, it will have an impact on the air volume. There are many reasons that can affect the air volume, such as insufficient intake pressure or too high an intake temperature
