How to solve the problem of insufficient gas production of screw air compressor?

2、 Air leakage problem
This is the most likely cause of this failure. You can start the oil free air compressor and stop it when the air storage tank has a certain pressure (slightly exceeding the atmospheric pressure). Then use your ears to listen for air leaks at connections such as external pipes, gas supply pipes, one-way valves, safety valves, and pressure switches. If there is a sound of air leakage, it needs to be repaired.
3、 Gas production standard
If the user adds equipment that requires gas, the gas consumption will exceed the gas production of the screw air compressor, indicating that the machine is overloaded. At this time, even if it continues to produce gas, it cannot meet your needs. You may think it lacks gas production. This type of case often occurs, so please carefully check whether your gas consumption has increased recently.
4、 Machine wear
Wear of the air compressor's male and female rotors: When there is significant wear between the male and female rotors and between the male and female rotors and the inner cavity of the stator, the internal leakage of the air compressor is very large, and the air compressor may be loaded without pumping air;
Air compressor lubricating oil: The price of screw type air compressor special oil is slightly higher. Some illegal suppliers provide users with non air compressor special oil, which causes emulsification of air compressor lubricating oil and fails to form an effective gas seal, resulting in very low efficiency of the air compressor and even no gas production. During this time, the compressor operator can hear that the noise of the vast majority of air compressors during actual full no-load and actual loading varies greatly, mainly due to the obvious noise at the suction end. When the internal leakage is large, there is a noise change at the suction end that does not generate pressure, which can confirm that the air compressor is slacking off and not pumping. Failure to pump air when loading an air compressor is a common air compressor fault. General professional air compressor maintenance personnel can help you quickly solve this problem.
5、 General reasons and solutions for non pumping of screw air compressor during loading
1. Intake valve not open:
After starting the air compressor, the internal pressure will first be slowly established. When the pressure reaches 5 Bar (this is the case for most air compressors, except for special cases), the solenoid valve controls the cylinder to open the intake valve, and the air compressor absorbs air into the loading state. There may be three reasons why the air compressor does not intake air. The solenoid valve (circuit, valve body, and pipeline), the cylinder (valve or membrane, seal, and pipeline), and the intake valve (valve or membrane, seal, and pipeline) have faults.
2. False loading of air compressor:
The false loading of the air compressor is mainly caused by a fault at the output point of the PLC, which is in the operating loading state. Due to the fault at the output point, there is no signal to the solenoid valve, resulting in the air intake machine not operating. The maintenance of the PLC requires a professional air compressor maintenance engineer, and non professionals are not recommended to disassemble it at will.
3. Minimum pressure check valve failure:
The minimum pressure check valve is the easiest to determine if there is a fault. When the internal pressure is high but there is no pressure output, it can be determined that the minimum pressure check valve has a fault. The best way to prevent the minimum pressure check valve from malfunctioning is to replace it.
6、 Cause of insufficient air pressure fault
Barometer malfunction
The oil water separator, pipeline, or air filter is clogged due to excessive deposits, requiring timely maintenance.
