The working principle of the Piston Rod is primarily dependent on its motion characteristics in a hydraulic or pneumatic drive system. The following is a detailed explanation of how the piston rod works:

1. Basic working principle

The Piston Rod is a key component that connects the piston to an executing part such as an oil cylinder or cylinder. In a hydraulic or pneumatic transmission system, when a high-pressure liquid or gas is injected into the cylinder or cylinder, these media will create pressure on the piston, pushing the piston to move in a straight line. The piston rod acts as an extension of the piston and transmits the movement of the piston to drive the working parts connected to it.

Second, the working principle of different application scenarios

Piston rod in hydraulic support: In hydraulic support, the piston rod is continuously contracted so that the top beam and the top plate are in real time contact. In this way, the roof pressure is dispersed, and then the protection of the roof is realized, so that the safety of use is effectively guaranteed. This is a typical application of piston rods in heavy equipment such as mining machinery.

Piston rod in hydraulic cylinder: The working principle of the piston rod in hydraulic cylinder is similar to that of the hydraulic support, but the specific structure and application scenarios may be different. For example, in a two-rod piston hydraulic cylinder, when the two pistons have the same diameter and the oil supply pressure and flow rate are unchanged, the hydraulic cylinder's action speed and output in the left and right directions are the same. In a single-rod piston hydraulic cylinder, because the effective area of the piston on both sides is different, the speed of the piston in the two directions may be different.

The working principle of the Piston Rod is based on the basic principles of a hydraulic or pneumatic drive system and enables the motion control of working parts through processes such as pressure transfer, motion conversion and load and transfer. In different application scenarios, the working principle of the piston rod may be different, but the basic principle is the same. Therefore, when designing and using the piston rod, it is necessary to fully consider factors such as its working environment, load conditions and movement requirements to ensure that it can work stably and reliably.
