Bahrain hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder

(Bahrain spring return cylinder,produced by Hengyu Group）

spring return cylinder are widely used in Bahrain，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed spring return cylinder for customers from Bahrain.

Introduction to spring return cylinder:

The cavitation of the spring return cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the spring return cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

spring return cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the spring return cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

The spring return 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 spring return cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The spring return cylinder is basically composed of spring return cylinder and spring return 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.

The difference between the integral spring return cylinder and the split spring return cylinder: The integral spring return cylinder and the split spring return cylinder in the spring return cylinder are two different spring return cylinders, and they are very different. The whole spring return cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split spring return cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and spring return cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Answers to some questions about spring return cylinder:

How many kinds of cylinder seal repair kit are there?
Very much, a wide variety of imported and domestic, J type, UHS, DHS, O-ring, Sterseal, etc., as well as support bars, materials are different, according to the size of the pressure selection is different, the appearance of the structure is different, the size is a variety, maintenance is generally selected according to the needs of the cylinder.

Why does the hydraulic cylinder rebound after the rod cavity is extended into place?
The reason is that after the rod cavity is extended into place, the rod cavity and the rodless cavity are connected, so that the cylinder moves towards the rod cavity. After connecting, it is equivalent to the hydraulic oil directly driving the cylinder with an area equal to the piston rod. After the end of this problem, it is estimated that the seal is not very good, and the two cavities are connected after the pressure is increased to a certain extent; Or there is a problem in the valve, so that the two chambers are connected after reaching a certain pressure. Other phenomena: If the load is increased to a certain extent, no matter which side of the solenoid valve is energized, the cylinder will move to the rod cavity.
