Libya hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder
(Libya supporting cylinder,produced by Hebei Hengyu company）
supporting cylinder are widely used in Libya，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed supporting cylinder for customers from Libya.
In order to ensure the service life of the supporting cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the supporting cylinder, causing damage to the seal and causing leakage in the supporting 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.
When the supporting cylinder is installed, the piston and the supporting cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the supporting cylinder head boss is easy to cause scars when it hits the inner surface of the supporting cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized supporting cylinders, only careful and careful operation can be avoided.
The method of sleeve supporting cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the supporting cylinder can be significantly improved by rolling in the finishing of the inner holes of the supporting cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
The body of the supporting cylinder on the processing process requirements: the body of the supporting cylinder is an important and essential part of the supporting cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the supporting cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.
