(Ghana hydraulic lifting cylinder,produced by Hebei Hengyu company）
hydraulic lifting cylinder are widely used in Ghana，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed hydraulic lifting cylinder for customers from Ghana.
The quality of the hydraulic lifting cylinder can not be ignored in the purchase of the hydraulic lifting cylinder. The hydraulic lifting cylinder is the main component of the hydraulic lifting cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. hydraulic lifting cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of hydraulic lifting cylinder is deep hole processing, which has always troubled the processing personnel.
In order to ensure the service life of the hydraulic lifting cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.
The method of sleeve hydraulic lifting 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 hydraulic lifting cylinder can be significantly improved by rolling in the finishing of the inner holes of the hydraulic lifting cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
hydraulic lifting cylinder buffer valve inspection and maintenance: For the valve buffer hydraulic lifting cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.
Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
