Uganda hydraulic cylinder,hydraulic lifting cylinder manufacturer,hydraulic lifting cylinder(Uganda hydraulic lifting cylinder,produced by Hengyu Group)
hydraulic lifting cylinder are widely used in Uganda,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed hydraulic lifting cylinder for customers from Uganda.
The pressure of the sliding surface of the hydraulic lifting cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the hydraulic lifting cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
In the case of serious wear on the inner surface of the hydraulic lifting cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the hydraulic lifting cylinder manufacturing process for replacement. The hydraulic lifting cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.
When the hydraulic lifting cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the hydraulic lifting cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.
If the hydraulic lifting cylinder slips or crawls, please check whether there is astringency inside the hydraulic lifting cylinder, because the internal parts of the hydraulic lifting cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the hydraulic lifting cylinder changes with the different stroke position, and the slip or crawl occurs. 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 hydraulic lifting 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.
What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.
