hoister hydraulic cylinder are widely used in Ireland，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed hoister hydraulic cylinder for customers from Ireland.

Introduction to hoister hydraulic cylinder:

If the hoister hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the hoister hydraulic cylinder. The internal parts of the hoister hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the hoister hydraulic cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the hoister hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the hoister hydraulic cylinder bore processing is out of whack. Because the piston and hoister hydraulic cylinder, guide rail and piston rod are relative If the hoister hydraulic cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling hoister hydraulic cylinder weight composition and calculation. The weight of the hoister hydraulic cylinder is composed of the hoister hydraulic cylinder diameter, the outer diameter and weight of the hoister hydraulic cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

hoister hydraulic cylinder installation precautions: Before installing the hoister hydraulic cylinder into the system, the parameters on the hoister hydraulic cylinder label should be compared with the parameters when ordering. The base of the hoister hydraulic cylinder must have sufficient stiffness, otherwise the hoister hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The hoister hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the hoister hydraulic cylinder should pay attention to: the operation should be as far away from the hoister hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the hoister hydraulic cylinder coating. When cleaning the hoister hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the hoister hydraulic cylinder when the oil temperature exceeds 70 ° C.

When the hoister hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the hoister hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the hoister hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about hoister hydraulic cylinder:

Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.

What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
