(Sweden stroke adjustable cylinder,produced by Hengyu Group）

stroke adjustable cylinder are widely used in Sweden，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed stroke adjustable cylinder for customers from Sweden.

Introduction to stroke adjustable cylinder:

The body of the stroke adjustable cylinder on the processing process requirements: the body of the stroke adjustable cylinder is an important and essential part of the stroke adjustable cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the stroke adjustable cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

When the stroke adjustable cylinder is in use, ensure that the stroke adjustable cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

In order to ensure the service life of the stroke adjustable cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the stroke adjustable cylinder, causing damage to the seal and causing leakage in the stroke adjustable cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

The cavitation of the stroke adjustable cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the stroke adjustable cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

Answers to some questions about stroke adjustable cylinder:

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.

What is a hydraulic cylinder assembly?
Assembly, which means aggregate. A series of parts or products, formed to achieve a specific function of the whole, the general term for this system is assembly. The hydraulic cylinder assembly is not a single hydraulic cylinder part, which can be used by connecting the hydraulic hose.
