France unidirectional cylinder

(France unidirectional cylinder,produced by Hengyu Group)

unidirectional cylinder are widely used in France,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed unidirectional cylinder for customers from France.

Introduction to unidirectional cylinder:

The piston seal of the unidirectional cylinder is the main element to prevent leakage in the unidirectional cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

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

When the unidirectional cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the unidirectional cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil unidirectional cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical unidirectional cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the unidirectional cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

Because of the slightly complex structure of the buffer unidirectional cylinder, sometimes there will be problems, such as when the unidirectional cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Answers to some questions about unidirectional cylinder:

Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.

What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.
