What are the effects of the failure of the internal parts of the screw air compressor on the equipment

How can I quickly diagnose the cause of an air compressor failure? I think only by having a good understanding of the internal structure of the air compressor and understanding the functions and functions of each accessory can we find the cause of the failure in time. The following compressor editor lists the impact of each air compressor accessory failure on the air compressor equipment, so that everyone can determine the cause of the failure in time for timely handling.

　　 1. The influence of oil filter blockage on the machine

　　 1. Rotor outlet temperature 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 oil cooler and the oil temperature of the cooler. If the temperature difference is too large, it means the oil The filter is clogged.

　　(2) The oil temperature is often too high, which will cause the oil quality to crack faster (normal working temperature is 75-95℃).

　　 2. The result of the oil and gas separator blockage

　　 1. Oil tank pressure rises

　　 2. Reduced outlet pressure

　　 3. Motor current rises

　　4. Cause the air compressor to trip

　　 5. Caused safety valve exhaust and fuel injection

　　6. ​​The oil and gas separator will be damaged due to excessive pressure and the cooling oil will be lost. Replace the oil and gas separator (the normal pressure difference is within 0.8kg)

　　 3. What is the impact on the machine when the oil cooler radiator is blocked?

　　 1. The temperature at the outlet of the rotor rises, causing a trip.

　　 2. The main motor is overloaded and tripped due to high temperature.

　　 3. The fan motor tripped due to overload 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 rotor outlet temperature rises, causing high temperature tripping.

　　 2. The cause is motor overload.

　　 3. The fan motor is overloaded.

　　4. The increase in air outlet temperature causes the load of the refrigeration dryer to increase. It is recommended that customers add air ducts and exhaust systems.

　　 5. What are the consequences if the minimum pressure check valve fails to close?

　　 1. The oil tank cannot rise after the machine is started, causing the air compressor to fail to load.

　　 2. The oil content of the outlet air increases.

　　3. The 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 minimum 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. The oil tank pressure will drop to 0kg during operation and the output pressure will stop. Check the cause of the belt break and install a new belt.

　　 Seven. What consequences will the intake valve fail to close?

　　 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, if it fails, replace it with a new one

　　 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 blown out. Remove the starter for maintenance.

　　 Nine, the external power supply voltage of the air compressor is too low, too high or three-phase unbalanced, what effect 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.
