Precision 860mm Carbon Steel Piston Forging 42CrMo4 Hydraulic Cylinder
The cylinder is also called hydraulic cylinder, the hydraulic energy into mechanical energy, to do straight reciprocating motion (or oscillating motion) of the hydraulic actuators. It has the advantages of simple structure, reliable working. Use it to realize the reciprocating motion, can avoid the reduction device, and there is no transmission clearance, the movement is steady, so it is widely used in the hydraulic system of all kinds of machinery. Hydrauli. Hydraulic cylinder output force and the effective area of the piston and the side pressure drop is proportional to.
The composition of hydraulic cylinder:
The hydraulic cylinder is basically composed of cylinder and the cylinder head, piston and piston rod, sealing and cushioning device and the exhaust device, device. Buffer device and the exhaust device depending on the specific applications, the other device is essential.
The working principle of:
Each cylinder's working principle is similar, with a manual Jack in its original work (Jack is also the most simple cylinder) by manual pressurization stalk (hydraulic manual pump) so that the hydraulic oil through a single valve into the tank, then enters the cylinder of the hydraulic oil can cause because of single valve then back up, forcing the cylinder rod upward, and then in the work to continue to make the hydraulic oil continuously into the hydraulic cylinder, so constantly on the rise, will open the hydraulic valve time to drop, the hydraulic oil back to tank.
The main oil cylinder to No. 45, 42CrMo based materials.
