What key points should be mastered when the piston air compressor starts?

When the piston air compressor is started, it is generally necessary to master the following key points:
1) first start the circulating oil pump, and check whether the running parts are filled with oil and whether the oil pressure is normal; start the high-pressure oil injector motor, and check whether the oil in each oil injector is normal; whether there is oil injection in the lubrication point of each cylinder.
2) open the cooling water valve, and check whether the return water of each cylinder and cooler is unblocked.
3) start the turning device or manual turning, check whether there is friction and abnormal sound between the motor stator and the rotor, whether there is barrier-free in all levels of cylinder, and whether the transmission mechanism is normal. Then turn the rotor disk to the driving position, take off the gear that the disc machine meshes with the rotor, and fix it.
4) Check whether the switch position of each valve is correct to start without any load.
5) check whether all indicating instruments are in good and normal indicating state.
6) get in touch with the front and back procedures and get ready to drive.
7) The pressure must rise slowly when driving and pay attention to the situation of pressure ratio at all levels.
