Why is it so difficult to turn on the air energy compressor after it is turned off

There may be many reasons why it is particularly difficult to turn on the air energy compressor after it is turned off. The following are several possible explanations:

1. high starting pressure: After the compressor is stopped, the pressure in the system may gradually equalize, resulting in the need to overcome a higher initial pressure when starting again. This is particularly true in high pressure ratio systems.

2. Electrical problems: Starting the motor may require a large starting current. If the grid voltage is unstable or the power line is over-extended, the voltage drop will affect the starting torque of the motor and make starting difficult.

3. Mechanical friction: The mechanical parts inside the compressor may increase friction due to the loss of lubricating oil or cooling after shutdown, and these frictional resistances need to be overcome when starting again.

4. System air leakage: If the compressor system has air leakage, the pressure in the system will drop rapidly after shutdown, and the pressure needs to be rebuilt when starting again, which will increase the difficulty of starting.

5. Control logic: Some compressors are equipped with a complex control system, including pressure sensors, temperature sensors and start/stop logic. Improper or faulty control system settings can also cause difficulty in starting.

Question: How to avoid the laborious problem of turning on the air energy compressor after it is turned off?

Answer: In order to avoid the problem that the air can compressor is turned off and then turned on, the following measures can be taken:

1. regular inspection and maintenance: ensure that the mechanical parts of the compressor are in good condition, and the lubricating oil is sufficient and clean.
2. Stable grid voltage: to ensure that the power supply line voltage stability, to avoid the voltage drop caused by long lines.
3. Check the tightness of the system: regularly check the system for air leakage and repair it in time.
4. Optimize the control logic: ensure that the control system of the compressor is set up reasonably and trouble-free.
5. Preheating start: In a cold environment, you can consider using a preheating device to preheat the inside of the compressor to prevent the water from freezing inside the water-lubricated air compressor head and reduce the frictional resistance during startup.
