Uzbekistan hydraulic cylinder,hydraulic hollow cylinder manufacturer,hydraulic hollow cylinder(Uzbekistan hydraulic hollow cylinder,produced by Hengyu Hydraulic Co., Ltd)
hydraulic hollow cylinder are widely used in Uzbekistan,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed hydraulic hollow cylinder for customers from Uzbekistan.
In recent years, the processing process of the hydraulic hollow cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.
The material of the sliding part of the hydraulic hollow cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.
Disassembly hydraulic hollow cylinder: When disassembly hydraulic hollow cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the hydraulic hollow cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the hydraulic hollow cylinder.
How is the hydraulic cylinder selected in the mechanical design manual?
First of all, it is necessary to meet your work needs, and the second is to meet the structural space of the cylinder and accessories. Three to consider the other parameters of the cylinder.
How to change the seal ring of lift oil cylinder of forklift truck?
Remove the cylinder, put it on the vise, first screw off the big nut plug on the head, and then pull out the guide sleeve, you can directly pull out the core of the cylinder, if it is to change the seal of the cylinder head, the core does not need to be pulled out, if it is to change the seal inside, pull it out and see the oil seal, remove it and replace it, there are three seals of the cylinder head, the inner seal, The outer seal, dustproof, it is best to replace them all together, and be sure to keep them clean when changing, and you can lubricate them with clean hydraulic oil.
