Several points are summarized in terms of extending the service life of the hydraulic cylinder. First of all, reasonable maintenance of the hydraulic cylinder should be carried out, including checking whether the fastener is loose. In order to maintain its effective compact state; Keep the hydraulic oil clean. Dirt in the oil may damage system components. Maintain the hydraulic fluid flow. Lack of oil will allow air to enter and prevent the system from working properly.

Pay attention to the oil leakage phenomenon shows that the seal damaged, not timely replacement, not only the cost of oil, but also the production decline, serious when not action. Familiar with the sound of system operation, there is a difference between normal and difficult sounds. When you hear different sounds, you should know that you have difficulties, and eliminate them in time, so as to avoid small troubles turning into big damage and causing big losses. 

The 0 seal circle in the hydraulic cylinder is easy to be damaged. When the "0" seal circle of the cylinder is worn, the cylinder has a rod cavity and the gap of the non-rod cavity becomes larger, which is equivalent to cutting off the cylinder and having a rod cavity to return oil. In practice, because of the interaction between the two cylinders, the pressure oil in the mechanical cylinder chamber often flows from the high pressure area to the low pressure area. Once flow occurs, the piston will lose balance and move to the bar cavity to find a new equilibrium point. This will reciprocate until an external force stops the piston.

The above phenomena have great influence on the operation of hydraulic system. After replacing the "0" seal ring of cylinder piston, it can completely improve the unstable working of cylinder and greatly extend the service life of mechanical cylinder. Hydraulic cylinder production cylinder refers to a part of the machinery, such as our daily guidance of the elevator, excavator, hydraulic machinery and other construction machinery will use hydraulic mechanical cylinder.

It is the lift in the whole process of the driving force from and transmission method, hydraulic transmission is inseparable from the hydraulic cylinder. The hydraulic transmission system is a key part of the hydraulic lifting platform. The hydraulic cylinder is the management mechanism in the hydraulic transmission system, which is usually composed of the engine cylinder block, cylinder rod and hydraulic seals. When feeding at one of the inlet ports, the piston rod will be promoted to make the other inlet pump oil, the piston rod will push the hydraulic cylinder to do the lifting exercise, and vice versa.
