Kuwait hydraulic cylinder,tension cylinder manufacturer,tension cylinder(Kuwait tension cylinder,produced by Hebei Hengyu company)
tension cylinder are widely used in Kuwait,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed tension cylinder for customers from Kuwait.
In recent years, the processing process of the tension 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, shape and compression of the tension cylinder seal have a great impact on the service life and work efficiency of the tension cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.
tension cylinder installation precautions: Before installing the tension cylinder into the system, the parameters on the tension cylinder label should be compared with the parameters when ordering. The base of the tension cylinder must have sufficient stiffness, otherwise the tension cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
tension cylinder can not drive the load troubleshooting: oil pressure is too low. tension cylinder selection specifications are too small. Leakage in tension cylinder or associated hydraulic system element.
Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.
