What are the dangers of starting without pressure relief at the high-pressure end of the compressor?
It is very dangerous, just like the air conditioner cannot be started frequently, it will explode.
There is definitely a danger. Pressure relief is for light load startup. If the pressure is not relieved during startup, it will be heavy load, which may cause the instantaneous current of the motor to exceed the standard and the motor to burn out easily. Generally speaking, the motor has protection and is not a big problem. The most important thing is that the piston force of the compressor is relatively large during startup, which has a large impact on the transmission part, and the life of the wearing parts of the transmission part will be shortened!
If the pressure is not released, the starting force will increase a lot, which may damage the machine.
We are turbine driven and have started the syngas compressor twice like this. In order to shorten the driving time, the high-pressure end pressure is about 10MPA and the low-pressure end is about 2.4MPA. The anti-surge valve is fully opened and no abnormality is found.
