(Cameroon steering cylinder,produced by Hengyu Group）

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

Introduction to steering cylinder:

The steering cylinder should be vented: when the steering cylinder is installed or parked for a long time to work again, the air will penetrate into the steering cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the steering cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the steering cylinder, the oil is best entered and discharged from the highest point of the steering cylinder. steering cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Piston steering cylinder is widely used in hydraulic transmission. When the steering cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the steering cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the steering cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

If the steering cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the steering cylinder. The internal parts of the steering 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 steering 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 steering 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 steering cylinder bore processing is out of whack. Because the piston and steering cylinder, guide rail and piston rod are relative If the steering 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 steering cylinder weight composition and calculation. The weight of the steering cylinder is composed of the steering cylinder diameter, the outer diameter and weight of the steering 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.

The meaning of the steering cylinder model marked by the steering cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the steering cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the steering cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

Answers to some questions about steering cylinder:

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.
