(Indonesia trunnion cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to trunnion cylinder:

If the trunnion cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the trunnion cylinder. The internal parts of the trunnion 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 trunnion 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 trunnion 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 trunnion cylinder bore processing is out of whack. Because the piston and trunnion cylinder, guide rail and piston rod are relative If the trunnion 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 trunnion cylinder weight composition and calculation. The weight of the trunnion cylinder is composed of the trunnion cylinder diameter, the outer diameter and weight of the trunnion 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 trunnion 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 trunnion cylinder should pay attention to: the operation should be as far away from the trunnion cylinder as possible, to avoid falling objects, knocking, rubbing the trunnion cylinder coating. When cleaning the trunnion cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the trunnion cylinder when the oil temperature exceeds 70 ° C.

Regular maintenance of the trunnion cylinder includes: regular tightening, trunnion cylinder fastening screws and gland screws, trunnion cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the trunnion cylinder once a year. Clean regularly, the trunnion cylinder is cleaned every other year, and the seals are replaced while cleaning.

trunnion cylinder can not drive the load troubleshooting: oil pressure is too low. trunnion cylinder selection specifications are too small. Leakage in trunnion cylinder or associated hydraulic system element.

Answers to some questions about trunnion cylinder:

What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.

Do the collecting cylinder, distributing cylinder and distributing cylinder on the organic heat carrier boiler need to be notified separately as the pressure vessel for construction?
Do not need to be installed as a separate pressure vessel to inform, according to the organic heat carrier boiler can be informed. Write a "special equipment installation, renovation and maintenance notice" issued on it.
