【Q&A Question 105】August 03, 2016: What are the factors that affect the displacement of a reciprocating compressor? The answer key will be available after responding; scoring is based on addressing the key points. Clearance volume, leakage loss, resistance of the intake valve, temperature of the intake gas. 3
Inlet pressure, outlet temperature, the load on the compressor, whether the inlet filter is clogged, the clearance of the compressor, the leakage rate of the compressor itself, the compressor’s air valves, and so on.
1. Low intake pressure； 2. High intake air temperature ； 3. Excessive clearance between the front and rear dead centers of the piston ； 4. The piston rings are severely worn ； 5. Sealing filler has severe air leakage ； 6. The air valve is not working properly.
High inhalation resistance, high inhalation temperature, poor sealing of the air valve, excessive clearance volume, leaks in the pipes or cooler, etc
It is related to the cylinder capacity of the piston; of course, once a gas reservoir is added, it becomes related to time as well. Additionally, temperature and the accompanying power source are also factors that influence it
Intake pressure, intake temperature, piston clearance, piston rings, sealing gaskets, etc
1. Influence of clearance volume. 2. Impact of inlet and exhaust resistance losses. 3. Influence of heat exchange between air and the cylinder wall. 4. The impact of exhaust pressure levels.
Inlet pressure, system pressure, clearance size, whether the air valve has internal leakage
The size of the clearance chamber, the quality of the unloading valve, the sealing of the piston rod, the sealing of the stuffing box, the pressure of the intake air, the temperature of the intake air, and the composition of the intake air
The amount of intake air, back pressure! The quality of the exhaust valve! The opening degree of the return tank!
