why a pressure of the screw air compressor does not increase?

There are more reasons for this, let’s eliminate them one by one first.First of all, you have to understand what is the flow of your air compressor , and whether it is proportional to your air consumption.If the screw air compressor itself cannot achieve the flow rate, what do you think is the problem?As the air compressor is old, the air output of the air compressor is far less than our air consumption.Or the air compressor has exceeded maintained  time and didn’t replaced the filter element , which may cause blockage.The pressure of this situation will naturally not rise.

There are several reasons why the pressure of the screw air compressor cannot rise

1.The screw air compressor uses too much air.It is recommended to check the pipeline for leaks;

2.The failure of the inlet valve of the screw air compressor resulted in insufficient valve opening. Remove the intake valve for maintenance first, or replace the repair kit;

3.The intake valve of the air compressor controls the air source to leak air, causing the valve to open insufficiently or unable to open.The leaking part needs to be eliminated;

4.The pressure switch setting of the air compressor is too low.The upper pressure limit should be adjusted upward;

5.The belt driven by the air compressor is too loose, causing the transmission efficiency to drop.The transmission belt needs to be adjusted, if it is damaged, replace it with a new one;

7.The air compressor's intake valve coupling is worn out and the opening is insufficient. The intake coupling needs to be replaced;

8.The reduced efficiency of the synchronous motor of the air compressor causes insufficient opening.Need to replace the synchronous motor with a new one;

9.The load solenoid valve of the screw air compressor is malfunctioning, and the air leakage causes insufficient air source.First remove the load solenoid valve for maintenance, if it cannot be repaired, replace it with a new one;

10.The air filter of the screw compressor is blocked.First remove the air filter for maintenance, if the filter is blocked, replace it with a new one;

11.The oil and gas separator of the screw air compressor is blocked.First check whether the pressure difference of the oil and gas separator has reached 0.8-1kg, if so, replace it with a new one;

12.The failure of the pressure switch of the air compressor caused the working pressure error.We need to overhaul the pressure switch, and replace it with a new one if it cannot be repaired;

13.The computer pressure setting value of the air compressor is too low or the pressure sensor is faulty.First adjust the computer settings and calibrate the pressure transmitter,If the transmitter fails, replace it with a new one;
