(S.Africa self-locking hydraulic cylinder,produced by Hebei Hengyu company）

self-locking hydraulic cylinder are widely used in S.Africa，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed self-locking hydraulic cylinder for customers from S.Africa.

Introduction to self-locking hydraulic cylinder:

The machining accuracy of the self-locking hydraulic cylinder depends on the level of equipment, production technology and testing means. self-locking hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

self-locking hydraulic cylinder use should try to avoid sealing belt into the self-locking hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the self-locking hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the self-locking hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

The definition of the minimum stable speed refers to the minimum movement speed of the self-locking hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the self-locking hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.

Answers to some questions about self-locking hydraulic cylinder:

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
