What is the reason for the high pressure of the screw compressor
- The exhaust valve or safety cover is not sealed and leaks, which increases the suction pressure of the screw compressor.
- The gas transmission efficiency of the compressor is reduced, the gas transmission volume is reduced, the gap is large, the sealing ring is worn too much, and the suction pressure is increased.
- If the heat load of the warehouse suddenly increases, the refrigeration capacity of the compressor is insufficient, which will cause the suction pressure to be too high.
- The expansion valve of the system is improperly adjusted or the temperature sensing bag is tightened, the oil suction pipe or throttle valve is opened too large, the float valve is faulty or the ammonia pump system is circulated too much, resulting in excessive liquid supply. The suction pressure of the compressor is too high. When the pressure of the screw compressor is too high or too low, check in time whether the intake valve is fully open, whether the current is within the normal range, whether the external useful air volume has increased, or whether there is any leakage.
