In addition to the maintenance of large components in the daily maintenance of the screw air compressor, it is also necessary to check the various internal accessories during the daily routine. Are accessories that important? Yes, these large and small parts in the air compressor will have an impact on the machine when they are damaged, and it is very likely that this will cause a greater failure. This time we will take a look at the impact of the various parts on the air compressor. What impact.

Oil

1. The influence of oil filter blockage on the machine
1). The temperature of the rotor outlet rises;
2). The oil life is reduced.
(1) The normal oil filter pressure difference gauge is within 1kg. If it exceeds, it means the oil filter is blocked. The inspection method is: measure the oil temperature of the inlet oil cooler and the oil temperature of the outlet cooler. If the temperature difference is too large, it means oil filtration. The device is blocked.
(2) If the oil temperature is frequently too high, it will lead to faster oil quality cracking (normal working temperature is 75-95°C).

2. The result of the oil and gas separator blockage
1). Increased oil tank pressure
2). Reduced outlet pressure
3). Motor current rises
4). cause the air compressor to trip
5). Causes safety valve exhaust and fuel injection
6). It will cause the loss of cooling oil due to the damage of the oil and gas separator due to excessive pressure. Replace the oil and gas separator (the normal pressure difference is: within 0.8kg)

3. What is the impact on the machine when the radiator fin of the oil cooler is blocked
1). The temperature at the outlet of the rotor rises, causing the machine to trip.
2). The main motor is overloaded and tripped due to high temperature.
3). The fan motor is overloaded and tripped due to excessive negative pressure. Remove the cooler for cleaning and maintenance.

4. What is the impact of poor ventilation and heat dissipation of the air compressor station on the machine
1). The temperature of the rotor outlet rises, causing high temperature tripping.
2). Caused by motor overload.
3). Cause the fan motor to overload.
4). The increase in air outlet temperature causes the load of the refrigeration and dryer to increase. It is recommended that customers add air ducts and exhaust systems.

5. What are the consequences if the pressure check valve fails to close?
1). After the machine is started, the oil tank cannot rise, causing the air compressor to fail to load.
2). The oil content of the outlet air increases.
3). On-site air will be poured back into the machine, causing the oil tank pressure to fail to drop when the vehicle is empty and causing the air compressor to spray fuel after stopping. Remove the pressure check valve for maintenance. If it fails, replace it with a new one.

6. What are the consequences of a broken transmission belt?
1). The machine cannot load after starting.
2) During operation, the oil tank pressure will drop to 0kg and the output pressure will stop. Check the cause of the belt break and install a new belt.

7. What are the consequences if the intake valve cannot be closed?
1). It will cause the pressure of the air compressor to continue to rise after being empty and cause the safety valve to exhaust.
2). The oil tank pressure rises when the vehicle is empty.
3). Cooling oil is poured back from the air inlet when parking. Remove the intake valve for maintenance and replace it with a new one if it fails

8. What impact will the poor contact of the starter connection point have?
1). The motor working current increases and causes the motor to overload.
2). The starter heats up and causes a malfunction.
3) The fuse is burned out. Remove the starter for maintenance.

9. The external power supply voltage of the air compressor is too low, too high or three-phase unbalanced, what impact will it have on the machine
1). Too low supply voltage will cause motor overload.
2). Excessive supply voltage will cause the motor resistance to decrease and burn out.
3). The unbalanced three-phase supply voltage will cause the motor to overload.
