The outlet pressure of the reciprocating machine is low
Thread Content
The pressure in the first cylinder of SJ254 is normal, the inlet pressure of the second cylinder is normal, but what’s the reason for the low outlet pressure of the second cylinder? The unit was checked and there are no issues; the process is fine, and the outlet check valve is in good condition. Unit A is working properly, while Unit B is experiencing the problems mentioned above
“The unit is fine, and there are no issues with the process; but is there a problem with the instrument readings?
Valve leakage and worn piston rings can both cause low pressure.
Check the inlet valve and outlet valve of the secondary cylinder. First, determine whether the valve is leaking. If the valve is in good condition, then check whether the piston ring clearance is too large!
