Germany stroke adjustable cylinder

(Germany stroke adjustable cylinder,produced by Hengyu Group)

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

Introduction to stroke adjustable cylinder:

The daily inspection of the stroke adjustable cylinder includes: checking the connection of the stroke adjustable cylinder and the pipe joint for leaks. Check the stroke adjustable cylinder rod for leaks. Check the stroke adjustable cylinder connection for leaks. When the stroke adjustable cylinder moves, the work is normal and smooth. Whether the stroke adjustable cylinder has internal leakage.

When the long-stroke stroke adjustable cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in stroke adjustable cylinder head seal damage, oil leakage, and piston sleep in the stroke adjustable cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the stroke adjustable cylinder; The piston and the piston rod are connected with a spherical joint.

The stroke adjustable cylinder is mainly composed of body, piston, piston rod, stroke adjustable cylinder head, stroke adjustable cylinder bottom, piston rod head and related auxiliary devices. The piston divides the stroke adjustable cylinder into two chambers, and moves reciprocally in the stroke adjustable 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 stroke adjustable cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the stroke adjustable 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 stroke adjustable 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 stroke adjustable cylinder bottom and the stroke adjustable cylinder head is serious, so the buffer deceleration should be set at both ends of the stroke adjustable cylinder The working medium of the stroke adjustable cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; stroke adjustable 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 stroke adjustable cylinder: The buffer structure of the stroke adjustable cylinder is to prevent the piston from colliding with the stroke adjustable cylinder head at the end of the stroke.

The stroke adjustable cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

Answers to some questions about stroke adjustable cylinder:

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
