Slovenia extra long cylinder

(Slovenia extra long cylinder,produced by Hengyu Group)

extra long cylinder are widely used in Slovenia,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed extra long cylinder for customers from Slovenia.

Introduction to extra long cylinder:

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

The piston seal of the extra long cylinder is the main element to prevent leakage in the extra long 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.

How to repair the extra long cylinder body when it is damaged: When the extra long cylinder has trace deformation and shallow tensile marks, the extra long cylinder is repaired by strong honing process. The heavy honing process can repair extra long cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the extra long cylinder can meet the technical requirements.

When the extra long cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the extra long cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

Answers to some questions about extra long cylinder:

What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).

How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.
