Troubleshooting methods for carbon dioxide compressor

Failure phenomenon of carbon dioxide compressor: pressure rise to a certain extent

Cause Analysis:

1. The intake valve of the next stage or the exhaust valve of this stage leaks, and the gas leaks into the cylinder of this stage.

2. Exhaust valve, cooler and pipe are dirty, blocking the passage

Removal method:

1. Clean the intake and exhaust valves, check the valve plates and springs, and repair the valve seats.

flat

2. Clean the cooler and pipes

3. Check the piston ring, and then insert the lock position into each other.

Carbon dioxide compressor failure phenomenon: a certain level of pressure drop

Cause Analysis:

1. Intake valve leakage level

2. Piston ring wear and leakage and piston ring wear and failure at this stage

3. The pipe connection is not sealed, resulting in air leakage

Removal method:

1. Clean the exhaust valve, check the valve spring and valve plate, and trim the valve seat surface.

2. The piston ring lock was misaligned and the piston ring was replaced.

3. Tighten the joint or replace the gasket

Failure phenomenon of carbon dioxide compressor: compressor displacement drops significantly

Cause Analysis:

1. Leakage of air valve and piston ring

2. The gasket of the piping system is not tightened

3. The air intake pipe is too strong or the air supply is insufficient

Removal method:

1. Check the air valve and piston ring, but make a judgment based on the pressure of each level in advance.

2. Replace the damaged gasket and tighten the joint

3. Check the gas supply pipeline and gas flow
