self-locking hydraulic cylinder are widely used in Nigeria，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed self-locking hydraulic cylinder for customers from Nigeria.

Introduction to self-locking hydraulic cylinder:

When the self-locking hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the self-locking hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the self-locking hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

The self-locking hydraulic cylinder is mainly composed of body, piston, piston rod, self-locking hydraulic cylinder head, self-locking hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the self-locking hydraulic cylinder into two chambers, and moves reciprocally in the self-locking hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the self-locking hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the self-locking hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the self-locking hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the self-locking hydraulic cylinder bottom and the self-locking hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the self-locking hydraulic cylinder The working medium of the self-locking hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; self-locking hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the self-locking hydraulic cylinder: The buffer structure of the self-locking hydraulic cylinder is to prevent the piston from colliding with the self-locking hydraulic cylinder head at the end of the stroke.

Most of the failure of the self-locking hydraulic cylinder is because there is a foreign body in the self-locking hydraulic cylinder into the failure of the self-locking hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the self-locking hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

When producing oil self-locking hydraulic cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

Answers to some questions about self-locking hydraulic cylinder:

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.

How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.
