Actual discharge volume of reciprocating compressor
Thread Content
What is the typical difference between the theoretical and actual discharge volume of a reciprocating compressor?
I’m not sure about the specifics, but I think the exhaust pressure shouldn’t be too low. If the reading on the dashboard differs significantly from the actual value, it’s likely due to a drop in pressure in your subsequent systems. If you reduce the size of the outlet valve, you’ll find that the exhaust pressure will gradually increase
Generally, the flow rate at the manufacturing plant is determined by adding 3% to the exhaust volume required by the user or the design institute; this information is provided in the compressor data sheet
I’m just asking for clarification: should the theoretical displacement or actual displacement remain more or less constant under different operating conditions (such as changes in ambient temperature), right? I mean the volumetric flow rate or volume flow of inhalation.
The volumetric efficiency of a reciprocating compressor unit is related to factors such as the suction pressure loss of the unit, cooling conditions, sealing performance, the compressing medium, and the clearance volume of the unit.
