In the process of using screw air compressor, sometimes there will be a low pressure failure, so what is the reason for the low pressure of the screw air compressor?
1. The air release valve is faulty (cannot be closed when loading);
2. The pressure switch setting is too low (relay control unit);
3. Pressure gauge failure (relay control unit); replace the pressure gauge;
4. Pressure switch failure (relay control unit); repair, replace the pressure switch if necessary;
5. Air leakage in the control pipeline: air leakage in the control pipeline of the air compressor will prevent the intake valve from being fully opened, so that the unit load cannot be full;
6. The air demand is greater than the supply: check whether the valve on the air supply pipeline is open or whether there is air leakage on the system, and reduce the air consumption;
7. The air filter is blocked: the function of the air filter is to filter the inhaled air to ensure that the air entering the air compressor is clean and clean. If the air filter element is severely clogged, it will affect the air intake of the unit. Therefore, its filter element must be replaced in time;
8. Pressure regulator malfunction or damage: The function of the pressure regulator system is to automatically adjust the compressor according to the customer's gas consumption to achieve a balance between supply and demand. Therefore, the damaged pressure regulator should be replaced in time, and the failed pressure regulator should be adjusted in time;
9. Oil and gas separator blockage: Because there are more or less impurities in the oil circuit system, after the filter element works for a period of time, blockage will occur, which will increase the resistance of the compressed air through the filter element and affect the normal operation of the unit. Therefore, the operator should replace the filter element in time according to the signal displayed on the monitor panel;
10. The intake valve cannot be fully opened: The function of the intake valve is to control the amount of intake air. When the unit is running at full load, the intake valve is fully open. When the air consumption required by the user decreases, the air volume adjustment device inputs compressed air to the intake valve to reduce the opening of the intake valve, thereby reducing the air intake of the compressor. The failure of the intake valve will affect the load of the unit. How many.
