Selection and maintenance of hydraulic cylinder to prolong service life.

With regard to the selection of hydraulic cylinders, we usually choose according to the inner diameter, stroke, service pressure and installation form of products. In fact, besides these, there are also the following points that deserve our attention. First, when the operating speed of hydraulic cylinders reaches a certain standard or above after loading, it is necessary to select cylinders with buffer devices, or when higher speed is reached, it is necessary to install deceleration valves outside the hydraulic cylinders. At the same time, attention should be paid to selecting suitable hydraulic oil and oil seal, and oil seals made of different materials should be selected for different hydraulic oils to ensure the service life of hydraulic cylinders. Of course, it is necessary to properly maintain the hydraulic cylinders during use. Considering that the cylinders need to bear greater pressure, the heavier the load, the greater the pressure will be, so it will be the most important part of the maintenance of the entire hydraulic system. In fact, for the hydraulic system, the hydraulic cylinder is like the heart. If there is a problem with the heart, it is difficult to repair it. Therefore, its maintenance needs to be careful and meticulous. First, attention should be paid to rust prevention during the maintenance. This is because the piston part needs to extend out of the cylinder in the working state, which will naturally be eroded by oxide and acid gas of truck cylinder. Therefore, we need to coat it with a proper amount of grease to protect it, so as to avoid the piston as a load-bearing component being eroded and possibly broken during work. Secondly, with the extension of service time, sometimes some foreign matters may be mixed into the hydraulic oil cylinder, so that the friction will increase during its operation, and the hydraulic oil itself has a certain service life, so it is necessary to change the oil regularly, so as to avoid negative impact on the device. During use, it is necessary to take precautions in advance, and the running speed of the hydraulic cylinder needs to be properly controlled, which can prolong the service life of the hydraulic cylinder. In addition, in order to protect the mechanism and be safe, the internal buffer device is also very effective for the protection of the cylinder. In terms of prolonging the service life of hydraulic cylinders, several points are summarized. Firstly, reasonable maintenance should be carried out for hydraulic cylinder manufacturers, including checking whether fasteners are loose, so as to keep them in an effective tight state and keep the hydraulic oil clean. The dirt in the oil will damage the system components and keep the hydraulic oil flow. Lack of oil will cause air to enter and make the system unable to work normally. Pay attention to the oil leakage phenomenon, which shows that the hydraulic tilt cylinder with damaged seal is not replaced in time, which not only consumes oil, but also reduces the output. If it is serious, it will not act. Be familiar with the sound of system operation. Normal and difficult sounds are different. If you hear different sounds, you will know that there are difficulties and eliminate them in time, so as to avoid small troubles turning into big damages and causing big losses. The easily damaged O-ring in hydraulic oil cylinder, when the O-ring of oil cylinder is worn, the oil cylinder has a rod cavity but no rod cavity clearance increases, which means that the oil cylinder has a rod cavity to return oil. In practice, due to the interaction between the two cylinders, the pressure oil in the mechanical oil cylinder cavity often flows from the high pressure area to the low pressure area. Once the flow occurs, the piston will lose its balance and move to the rod cavity to find a new balance point, which will reciprocate until the piston is displaced. The above phenomenon has a great influence on the operation of hydraulic system. After replacing the O-shaped sealing ring of cylinder piston, the unstable operation of cylinder can be completely improved, and the service life of mechanical oil cylinder can be greatly prolonged. The oil cylinder produced by hydraulic oil cylinder manufacturer refers to a part of machinery, such as the hydraulic mechanical oil cylinder used in elevator, excavator, hydraulic press and other construction machinery that we want to guide daily. Our company specializes in producing all kinds of truck accessories, mainly including cab lifting oil pump, cab lifting oil cylinder, forklift tilting oil cylinder and steering oil cylinder. At present, our company mainly focuses on European truck accessories, such as VLVO Volvo truck, BENZ Mercedes truck, SCANIA Caina truck, Manman truck, RENAULT truck, IVECO Iveco truck and DAF Duff truck.
