The hydraulic cylinder is an indispensable actuator in the hydraulic transmission system, which can provide powerful and stable power output for all kinds of equipment by converting hydraulic energy into mechanical energy efficiently and realizing linear reciprocating motion or small angle swing.
Its basic structure is composed of cylinder barrel, piston, piston rod, end cover, sealing assembly and buffer device.As the main part, the cylinder is made of high-strength seamless steel tube by precision machining, and the inner wall finish is Ra ≤ 0.4 μm, which ensures the smoothness and sealing of piston movement.The piston is rigidly connected with the piston rod and moves along the axis of the cylinder barrel under the push of high-pressure oil. The output thrust or tension can be flexibly adjusted according to the working pressure. The maximum thrust of a single cylinder can reach hundreds of tons to meet the requirements of heavy-duty operations.
The sealing system is the key to the hydraulic cylinder. It adopts the design of imported polyurethane combination seal and dust ring, maintains excellent performance within the temperature range of -30 ℃ to 120 ℃, can withstand the high pressure of 31.5MPa without leakage, and effectively prevents oil loss and impurity intrusion.The surface of the piston rod is chrome-plated with a thickness of 0.05-0.1mm and a hardness of HRC60-65, which significantly improves the wear resistance and corrosion resistance and prolongs the service life.
According to different application scenarios, the hydraulic cylinder can be customized into piston type, plunger type, telescopic type and other types, with the stroke ranging from 100mm to 5000mm. The installation method supports flange, earring, pin and other forms, which is suitable for engineering machinery, metallurgical equipment, ships, machine tools, agricultural machinery and other fields.Whether it is the shovel loading operation of the excavator, the lifting action of the crane, or the stamping processing of the press, it can ensure the efficient and accurate operation of the equipment by virtue of its efficient energy conversion (efficiency of more than 95%), fast response speed (start-up time ≤ 0.3 seconds) and stable operation performance.

We use this hydraulic cylinder on metallurgical equipment, the working pressure is often around 30MPa, and there has been no problem in operation for more than half a year.The previous cylinder is always a little deformed under high pressure, but this one is not at all. The thrust loss is very small. It is very easy to drive the heavy mould. It can really carry the heavy load.
There is a lot of dust on the construction site, and the previous oil cylinder will leak oil in a short time.After changing this model, I observed it for more than three months. The piston rod was clean and there was no oil stain at all.The double dust ring really works, and there is no dust in the bearing when it is taken apart. The number of maintenance times is much less, which saves a lot of effort.
The hydraulic equipment of our production line requires high precision. This cylinder starts very fast, almost without delay, and runs smoothly. The processing error of the product is much smaller than before.The piston rod looks very smooth and slightly worn. It has been used for almost a year, and the accuracy is still very good.
