The relationship between the inlet pressure and outlet pressure of screw compressors
Thread Content
Dear experts, I have a question: One of the instructions in the screw compressor manual states that under any operating conditions, the inlet pressure of the compressor must not be higher than the outlet pressure; otherwise, it may cause damage to the compressor. If the inlet pressure is higher than the outlet pressure before starting up, the inlet and outlet pressures should first be adjusted to be equal using the bypass valve before starting the machine. Why is it not allowed for the compressor inlet pressure to be higher than the outlet pressure? If this condition occurs, which part of the compressor will be damaged? Thank you!
This must be the instruction manual for the screw compressor of 711. Haha, as for the reason, it can’t be said casually
High outlet pressure, motor overload
