(Republic of Lithuania trunnion cylinder,produced by Hengyu Group）

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

Introduction to trunnion cylinder:

Piston trunnion cylinder is widely used in hydraulic transmission. When the trunnion cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the trunnion 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 trunnion 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.

trunnion cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

Improve the service life of the trunnion cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the trunnion cylinder (such as the trunnion cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the trunnion cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the trunnion cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single trunnion cylinder exhaust.

In order to ensure the service life of the trunnion cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the trunnion cylinder, causing damage to the seal and causing leakage in the trunnion cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

Answers to some questions about trunnion cylinder:

What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.

How to repair the bent oil cylinder correctly?
If the bending oil cylinder leaks, the most direct way is to replace the seal ring. Most of the sealing rings used by domestic bending machines are made in Taiwan and Japan, so the service life of the sealing ring is still relatively long. If the bending oil cylinder used by the customer leaks oil, then when replacing the seal ring, be sure to choose a high-quality and durable seal ring. In this way, the replaced cylinder will not leak oil for a long time.
