For example: when the stroke is 300MM and the thrust is 4000KG, which model should be selected for the hydraulic cylinder?

Select the model of hydraulic cylinder, mainly the inner diameter and working pressure of hydraulic cylinder.

According to the 4 tons of thrust provided by you, it can be calculated that if the working pressure of 8MPA is used to design the oil cylinder, the inner diameter of the oil cylinder is 80, the oil cylinder model is 80 * 40 * 300-8MPA, and the pull rod oil cylinder can be used, which is cheap and easy to maintain.

If the working pressure of the oil cylinder is 16MPA, the inner diameter of the oil cylinder is 60cm, and the oil cylinder model is 60 * 35 * 300-16cm, which can be welded or pull rod type.

It is recommended that you first determine the pressure of the oil cylinder in combination with the system pressure of mechanical equipment. For finishing machines, the system pressure is lower, generally lower than 5MPA. For rough machining, the system pressure is larger.

Cycloidal hydraulic motor of agricultural machinery Measure the system pressure of the equipment, calculate the inner diameter of the oil cylinder, and then determine BMR cycloidal motor The connection mode and installation mode of the oil cylinder, the end thread of the piston rod, and the specific size. Of course, the installation method of the oil cylinder is also related to the calculation process. For example, the oil cylinder is installed vertically, horizontally, or at an angle.

One additional point here: the selection of hydraulic cylinder needs to first determine the system parameters: ① the weight to be moved and the force required; ② Nominal working pressure and working range; ③ Time needed to move this distance; ④ Oil medium.

Installation mode: select the appropriate installation mode according to the specific application.

Cylinder inner diameter and working pressure: determine the cylinder inner diameter and the necessary pressure required by the system.

4、 Piston rod: OMR cycloidal hydraulic motor Determine the minimum piston rod diameter required to withstand bending moment, and select appropriate piston rod end and end thread.

Piston: whether the sealing type is suitable for the application.

Buffering: select appropriate buffering requirements according to the situation.

Oil port: Go to the proper oil port ① Can they reach the required speed? B Is the standard position acceptable?

Piston rod seal: select the seal matching the oil medium.

Accessories: Do you need piston rod end accessories?

Special characteristics: installation, materials, environment and oil.
