according to the thrust of 4 tons given by you, it can be inferred that if the service pressure of the oil cylinder is designed to be 8MPA, the inner diameter of the oil cylinder is 8 MPa, the model of the oil cylinder is 8*4*3-8MPA, and the pull-rod oil cylinder can be used, which is low in price and convenient to maintain.
if the service pressure of the oil cylinder is 16MPA, the inner diameter of the oil cylinder is 6 MPa, and the model of the oil cylinder is 6*35*3-16MPA, which can be welded or pull rod type.
it is recommended that you first determine the service pressure of the oil cylinder in combination with the system pressure of mechanical equipment. Mechanical equipment for finishing, the system pressure is lower, usually below 5MPA, if rough machining, the system pressure is higher.
Determine the system pressure of the equipment, then calculate the inner diameter of the oil cylinder, and then determine the connection mode, installation mode, piston rod end thread, specific installation size, etc. Of course, the installation mode of the oil cylinder is also related to the calculation process, such as whether the oil cylinder is installed vertically, horizontally or at an angle.
