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
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.
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
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
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
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
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
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
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
Cause Analysis:
Clogged the oil hole in the crankshaft or connecting rod
Method of exclusion:
Cleaning oil hole with compressed air
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
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
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
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
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.
