Luxembourg hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder
(Luxembourg trunnion cylinder,produced by Hengyu Hydraulic Co., Ltd）
trunnion cylinder are widely used in Luxembourg，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed trunnion cylinder for customers from Luxembourg.
When using the trunnion cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the trunnion cylinder block. If the trunnion cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the trunnion cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the trunnion cylinder, so that the working efficiency of the trunnion cylinder is reduced.
The body of the trunnion cylinder on the processing process requirements: the body of the trunnion cylinder is an important and essential part of the trunnion cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the trunnion cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
When the trunnion 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 trunnion cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the trunnion 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.
If the seal of the trunnion cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and trunnion cylinder, and the phenomenon of "pulling the trunnion cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.
What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.
A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.
