As the structure and size of various hydraulic cylinders are different, the disassembly sequence is slightly different. Generally, drain the oil in the two chambers of the oil cylinder, remove the cylinder head, and finally remove the piston and piston rod. Sichuan Hydraulic machinery When disassembling the cylinder head of the hydraulic cylinder, special tools shall be used for the key or snap ring of the internal key type connection, and flat shovel is prohibited; Flange end caps must be pushed out with screws, and hammering or hard prying is not allowed. When it is difficult to draw out the piston and piston rod, do not force them out, Sichuan Hydraulic machinery Price The reason shall be found out before disassembly. Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being polluted by the surrounding dust and impurities.

1、 If the groove is too deep, two situations will occur: A. If the gap between the seal root and the groove becomes larger, the seal root will become unstable. B. The interference between the sealing lip and the sealing surface becomes smaller, Sichuan Hydraulic machinery The rebound force of the seal becomes smaller, and the failure rate of low-pressure oil leakage will increase when the piston rod jumps. 2、 If the groove is too shallow, two situations will also occur: A. The interference between the sealing lip and the sealing surface will increase, and the contact area will increase, which will lead to greater friction, Sichuan Hydraulic machinery Price The increased heat accelerates the damage of the seal lip. B. As a result, the clearance at the seal root becomes smaller, and the probability of the seal root being squeezed out when the oil cylinder is under high pressure increases.

The speed ratio refers to the same flow (volume of liquid entering the hydraulic cylinder per unit time), Sichuan Hydraulic machinery Price The ratio of the piston rod extension speed to the retraction speed. The calculation is equal to the inverse ratio of the large cavity area and the small cavity area of the cylinder. The speed ratio is related to the cylinder diameter and rod diameter of the oil cylinder. Main products: harvesting machinery series Sichuan Hydraulic machinery Flip plow series, press series, grader series, TGL, HG, SG, DG series vehicle oil cylinder, HSG series engineering oil cylinder mining machinery, ship oil cylinder, and various non-standard oil cylinders. Welcome to order!

The connection between the oil cylinder and the actuator and the connection between the oil cylinder and the oil pipe cannot be the same, because there must be some differences between the connection between the oil cylinder and different products. In addition, during the use of the oil cylinder, it is necessary to avoid scratches, Sichuan Hydraulic machinery Because if this problem occurs, it will affect the normal use of the oil cylinder. At present, there is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders, and it is necessary to design hydraulic cylinders according to these standards. So far, Sichuan Hydraulic machinery Price There is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders.

Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating movement, the reducer can be avoided, Sichuan Hydraulic machinery And there is no transmission clearance, smooth movement, so it is widely used in various mechanical hydraulic systems. Output force of the hydraulic cylinder is proportional to effective area of the piston and pressure difference on both sides; The hydraulic cylinder basically consists of cylinder barrel, cylinder head Sichuan Hydraulic machinery Price The piston and piston rod, sealing device, buffer device and exhaust device are composed.
