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

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. The exhaust valve, cooler and pipeline are dirty, blocking the passage

elimination method:

1. Clean the intake valve and exhaust valve, check the valve plate and spring, and then repair the valve seat.

flat

2. Clean the cooler and pipeline

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

Failure phenomenon of carbon dioxide compressor: a certain degree of pressure drop

Cause Analysis:

1. The degree of intake valve leakage

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

3. The pipeline connection is not sealed, causing air leakage

elimination method:

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

2. The piston ring lock is not aligned, and the piston ring is replaced.

3. Tighten the joint or replace the gasket

Carbon dioxide compressor failure phenomenon: the compressor displacement is significantly reduced

Cause Analysis:

1. Leakage of air valve and piston ring

2. The gasket of the piping system is not compressed

3. The intake pipe is too strong or insufficient

elimination method:

1. Check the air valve and piston ring, but judge in advance according to the pressure of each level.

2. Replace the damaged gasket and tighten the joint

3. Check the gas supply pipeline and gas flow

CO2 compressor malfunction phenomenon: knocking sound of cylinder

Cause Analysis:

1. The clearance between piston and cylinder is too small

2. Metal fragments (such as valve springs, etc.) fall into certain types of cylinders.

3. Water enters the cylinder

elimination method:

1. Adjust the gap between the cylinder and the piston with an adjusting washer

2. Remove the fallen objects, such as the \"health\" of the cylinder and piston should be repaired

3. Remove oil and water in time

CO2 compressor malfunction phenomenon: knocking sound of intake and exhaust valves

Cause Analysis:

1. The suction valve and exhaust valve valve are damaged

2. The valve spring is soft or damaged.

3. When the valve seat is installed in the valve cavity, it will not be at positive pressure or valve cavity pressure.

Bolt is not tight

elimination method:

1. Check the air valve on the cylinder to replace the severely worn or damaged valve gas.

2. Replace the spring that meets the requirements

3. Check if the valve is installed correctly and tighten the bolts

CO2 compressor failure phenomenon: noise from rotating parts

Cause Analysis:

1. The connecting rod big end bushing and small end bushing are worn or burnt.

2. The connecting rod screw is loose, the trip is broken, etc.

3. Cross pin wear

4. The gap between the two ends of the crankshaft is too large

5. Belt pulley key wear or axial movement

elimination method:

1. Replace the big head bushing and small head bushing

2. Check whether the split pin is damaged. If the screw is found to be elongated or damaged, it should be replaced.

3. Replace the cross pin

4. Replace with new bearings

5. Replace the key and tighten the nut to prevent displacement

Symptoms of carbon dioxide compressors: the pressure gauge reading drops significantly or drops to zero

Cause Analysis:

1. The pressure gauge pipe joint is not tightened.

2. Pressure gauge failure

3. There are oil and water in the pressure gauge

elimination method:

1. Check and tighten the pipe joints

2. Replace the pressure gauge

3. Dry the oil and water in time

Failure phenomenon of carbon dioxide compressor: lubricating oil pressure drops

Cause Analysis:

1. The oil net is dirty or the oil sump is short of oil.

2. The lubrication system seals the leaking oil into the oil pipe

3. The motor reverses or the speed is lower than the rated speed

4. The lubricating oil is too thick to absorb oil

elimination method:

1. Clean the core carefully and blow with compressed air to refuel the oil pool according to the time.

2. Tighten the screw to replace the damaged washer

3. Reverse motor wiring and increase speed

4. Heat the lubricating oil to reduce the concentration

Carbon dioxide compressor failure phenomenon: increased oil pressure

Cause Analysis:

The oil hole in the crankshaft or connecting rod is blocked

elimination method:

Clean the oil hole with compressed air

Fault phenomenon of carbon dioxide compressor: abnormal oil filling volume of oiler

Cause Analysis:

1. The oil suction net is blocked or the oil pipe is blocked or there is cracked oil in the oil pipe.

2. The required wear pressure does not cover the oil pump column and pump body of the oiler.

3. The oil adjustment is not suitable, so that the amount of oil is too much or too little

elimination method:

1. Clean the filter, oil pipe, and check the oil pipe to replace and repair damaged oil.

2. Repair or replace with new parts

3. The process of re-adjusting the oil pump

Carbon dioxide compressor failure phenomenon: the motor hums and the speed decreases.

Cause Analysis:

1. The phase fuse is blown, causing two-phase operation

2. Friction between motor rotor and stator

elimination method:

1. Stop immediately

2. Check the motor

CO2 compressor symptoms: the ammeter indicates abnormal motor overheating.

Cause Analysis:

1. The main bearing is burned out

2. The cross pin bushing is burnt out

3. The connecting rod big head tile is damaged

elimination method:

1. Change to a new one

2. Replace with new accessories

3. Replace with new accessories

Carbon dioxide compressor failure phenomenon: bearing overheating

Cause Analysis:

1. The radial clearance between the bearing and the journal is too small

2. Insufficient oil or excessive oil

elimination method:

1. Adjust to normal gap

2. Check the fuel supply

Carbon dioxide compressor symptoms: vibration or noise

Cause Analysis:

1. The main body is not strong

2. Loosen the anchor bolts

3. The bearing is faulty

elimination method:

1. Check the cause of vibration, strengthen the foundation and installation

2. Tighten the nut

3. Adjust the gap or replace

If you buy other machines, for exampleOxygen compressor,Hydrogen compressorWait, be sure to repair when there is a problem, it will save you a lot of money.
