stern plate hydraulic cylinder are widely used in Nepal，because of long service life，clever hydraulic energy conversion，no transmission clearance.So our company has designed stern plate hydraulic cylinder for customers from Nepal.

Introduction to stern plate hydraulic cylinder:

If the piston rod and stern plate hydraulic cylinder are stuck or the stern plate hydraulic cylinder is blocked, at this time, no matter how to operate, the stern plate hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the stern plate hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

Most of the failure of the stern plate hydraulic cylinder is because there is a foreign body in the stern plate hydraulic cylinder into the failure of the stern plate hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the stern plate hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

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

Answers to some questions about stern plate hydraulic cylinder:

What is st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.

How to design the guide sleeve of cylinder diameter 400?
The purpose of the guide sleeve is to guide and seal. Therefore, it is necessary to look at the speed of the piston rod, working pressure and radial force. High speed, medium pressure, no (or very little) radial force, with a Steseal. Low speed and heavy load, medium radial force, combined seal. High speed and heavy load, large radial force, sealed with DU sleeve + copper ring + combination. The combination seal must have a lubricating oil passage, and a seal must be added to the outside of the oil passage.
