(El Salvador unidirectional cylinder,produced by Hengyu Group）

unidirectional cylinder are widely used in El Salvador，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed unidirectional cylinder for customers from El Salvador.

Introduction to unidirectional cylinder:

When producing oil unidirectional 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.

When the hydraulic oil is not pumped into the unidirectional cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the unidirectional cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

If air enters the hydraulic system, the unidirectional cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

The unidirectional cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the unidirectional cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The unidirectional cylinder is basically composed of unidirectional cylinder and unidirectional cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

Answers to some questions about unidirectional cylinder:

How to determine the rated working pressure of the hydraulic cylinder?
Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.

What are the main technical parameters of the hydraulic cylinder?
Parameters are as follows: 1, cylinder diameter, inner diameter size; 2, import and export diameter and thread parameters; 3, piston rod diameter; 4, cylinder pressure, cylinder working pressure, calculation is often used test pressure, less than 16MPa multiplied by 1.5, higher than 16MPa multiplied by 1.25. 5, cylinder stroke; 6. Is there a buffer? According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7, the installation of the cylinder.
