CO2 compressors have also been greatly developed, and it is not easy to choose a good CO2 compressor from many manufacturers. After the purchase, more attention should be paid to the maintenance of the CO2 compressor.


main:

CO2 compressor fault phenomenon: a certain level of pressure rises

CO2 compressor fault phenomenon: a certain level of pressure drop

CO2 compressor fault phenomenon: the displacement of the compressor drops significantly

CO2 compressor fault phenomenon: knocking sound occurs in the cylinder

CO2 compressor fault phenomenon: the knocking sound of the suction and exhaust valve

CO2 compressor fault phenomenon: noise at the rotating part

CO2 compressor symptom: Pressure gauge reading drops significantly or decreases to zero

CO2 compressor fault phenomenon: lubricating oil pressure is reduced

CO2 compressor fault phenomenon: oil pressure rises

CO2 compressor fault phenomenon: the oil quantity of the oiler is not normal

CO2 compressor fault phenomenon: the motor is humming and the speed is decreasing.

CO2 compressor symptom: The ammeter indicates that the abnormal motor is overheated.

CO2 compressor fault phenomenon: bearing overheating

CO2 compressor symptom: vibration or noise

 

CO2 compressor fault phenomenon: a certain level of pressure rises 

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 valves, coolers and pipes are dirty and fouled, blocking passages

Method of exclusion:

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

flat

2, cleaning the cooler and pipeline

3. Check the piston ring and insert the positions of the locks into each other.

 

CO2 compressor fault phenomenon: a certain level of pressure drop 

Cause Analysis:

1. This level of intake valve leakage

2. This stage piston ring wear leakage and piston ring wear and failure

3, the pipe connection is not sealed, causing air leakage

Method of exclusion:

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

2. The piston ring locks are misaligned and the piston ring is replaced.

3. Tighten the joint or replace the gasket

 

CO2 compressor fault phenomenon: the displacement of the compressor drops significantly

Cause Analysis:

1. Air valve and piston ring leak

2, the piping system gasket is not compacted

3, the intake pipe is too strong or insufficient gas supply

Method of exclusion:

1. Check the air valve and piston ring, but it should be judged according to 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

CO2 compressor 

CO2 compressor fault phenomenon: knocking sound occurs in the cylinder

Cause Analysis:

1, the piston and cylinder clearance is too small

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

3, water enters the cylinder

Method of exclusion:

1. Adjust the clearance between the cylinder and the piston with the adjusting washer

2, remove the dropped objects, such as cylinders and pistons "raw" should be repaired

3. Remove oil and water in time

 

CO2 compressor fault phenomenon: the knocking sound of the suction and exhaust valve

Cause Analysis:

1. Suction and exhaust valve flaps are broken

2. The valve spring is soft or damaged.

3. When the valve seat is installed in the valve chamber, it is not placed in the positive or the pressure on the valve chamber.

Bolts are not tight

Method of exclusion:

1. Check the air valve on the cylinder to replace the valve gas with severe wear or breakage.

2, replace the spring that meets the requirements

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

 

CO2 compressor fault phenomenon: noise at the rotating part 

Cause Analysis:

1. The connecting rod big head bush and the small head bushing are worn or burned off.

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

3, cross pin wear

4, the gap between the ends of the crankshaft is too large

5. Pulley key wear or axial movement

Method of exclusion:

1. Replace the large head bush and the small head bushing

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

3, replace the cross pin

4, replace the new bearing

5, replace the key and tighten the nut to prevent displacement

 

CO2 compressor symptom: Pressure gauge reading drops significantly or decreases to zero

Cause Analysis:

1. The pressure gauge pipe joint is not tightened.

2, the pressure gauge is faulty

3, there is oil and water in the pressure gauge

Method of exclusion:

1. Check the pipe joint and tighten

2, replace the pressure gauge

3, timely blow off oil and water

 

CO2 compressor fault phenomenon: lubricating oil pressure is reduced

Cause Analysis:

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

2. Lubrication system seals oil leakage into the oil pipe

3, the motor reverses or the speed is lower than the rated speed

4, the lubricating oil is too thick, the oil can not be sucked

Method of exclusion:

1. Carefully clean the core and blow it with compressed air to refuel the oil pool according to time.

2. Tighten the screws to replace the damaged gasket

3. Reverse the motor wiring and increase the speed

4, the lubricating oil is heated to reduce the concentration

 

CO2 compressor fault phenomenon: oil pressure rises

Cause Analysis:

Clogged the oil hole in the crankshaft or connecting rod

Method of exclusion:

Cleaning oil hole with compressed air

 

CO2 compressor fault phenomenon: the oil quantity of the oiler is not normal 

Cause Analysis:

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

2. The oil pump column and the pump body of the oiler are not covered by the required wear pressure.

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

Method of exclusion:

1. Clean the filter, tubing, and check the oil pipe for replacement and repair of the broken oil.

2. Repair or replace new parts

3. Re-adjust the process of the oil pump

 

CO2 compressor fault phenomenon: the motor is humming and the speed is decreasing.

Cause Analysis:

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

2. Motor rotor and stator friction

Method of exclusion:

1, parking immediately

2, check the motor

 

CO2 compressor symptom: The ammeter indicates that the abnormal motor is overheated.

Cause Analysis:

1, the main bearing burned out

2, the cross pin bushing burned out

3, the connecting rod big head bearing tile is broken

Method of exclusion:

1, for a new

2, replaced by new accessories

3, replaced by new accessories

 

CO2 compressor fault phenomenon: bearing overheating 

Cause Analysis:

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

2. The oil quantity is insufficient or the oil quantity is too high

Method of exclusion:

1, adjust to normal clearance

2, check the oil supply situation

 

CO2 compressor symptom: vibration or noise

Cause Analysis:

1, the main body is not solid

2, loose anchor bolts

3, the bearing is faulty

Method of exclusion:

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

2, tighten the nut

3, adjust the gap or replace

 

If you purchase other machines, such as oxygen compressors, hydrogen compressors, etc., be sure to repair them when problems occur, which will save you a lot of money.
