PM-46 pneumatic motor

Does the motor for the pneumatics have veins? One of ours gets up to pressure so it can start printing but then the motor just keeps chugging and chugging, it does sound a little weaker than our other PMs. It also has a rattle sometimes so I don’t know what that would be.

 

Hi sir
yes normally the pneumatic motor must have one or two pistons depending on the model.
but to know the cause of the problem please make sure that you do not have any leaks at the level of the machine, the piping and the cylinders but to have an idea on the compressor please put it in a closed circuit (close the valve towards the machine) and start it it must reach its pressure in 30 seconds like that you can know if the problem is in the machine or in the compressor
Good luck
