(Uruguay trunnion cylinder,produced by Hengyu Group）

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

Introduction to trunnion cylinder:

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the trunnion cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

trunnion cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the trunnion cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

The trunnion cylinder should be vented: when the trunnion cylinder is installed or parked for a long time to work again, the air will penetrate into the trunnion cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the trunnion cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the trunnion cylinder, the oil is best entered and discharged from the highest point of the trunnion cylinder. trunnion 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.

trunnion cylinder body inspection: The inner surface of the trunnion cylinder and the piston seal are the main factors causing the leakage in the trunnion cylinder, if the trunnion cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the trunnion cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Answers to some questions about trunnion cylinder:

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.

What hydraulic oil does servo cylinder generally use?
The medium used by the cylinder generally depends on the working condition of the use, including pressure, installation environment, sealing material, etc. I think the first thing to consider is the impact of the sealing material. Mineral oil is a good choice if it is not too fire-resistant or used in a high temperature environment. 1, servo cylinder features: closed-loop servo control, control accuracy of 0.01mm; Precise control of thrust, increase pressure sensor, control accuracy up to 1%; It is easy to connect with PLC and other control systems to achieve high precision motion control. Low noise, energy saving, clean, high rigidity, impact resistance, long life, simple operation and maintenance. 2, the servo cylinder can be fault-free in harsh environments, and the protection level can reach IP66.
