Japan hydraulic cylinder,unidirectional cylinder manufacturer,unidirectional cylinder(Japan unidirectional cylinder,produced by Hebei Hengyu company)
unidirectional cylinder are widely used in Japan,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed unidirectional cylinder for customers from Japan.
The unidirectional cylinder is not the same as the unidirectional cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the unidirectional cylinder can not be used as a high-power power component, but the unidirectional cylinder can be used as a relatively large power component, or the unidirectional cylinder system can be used.
The pressure of the sliding surface of the unidirectional cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the unidirectional cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
In order to ensure the service life of the unidirectional cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the unidirectional cylinder, causing damage to the seal and causing leakage in the unidirectional 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.
After chrome plating of the piston rod of the unidirectional cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
What is the material of the hydraulic cylinder slider?
Three parts of the hydraulic cylinder are essential, which are: cylinder - cylinder head assembly, piston - piston rod assembly, and sealing device. When you say slider, you mean piston. - Piston rod. Piston materials commonly used gray cast iron, wear-resistant cast iron, aluminum alloy (assembled), etc., can also be used 35 and 45 steel (integral). The piston rod is generally made of 35 and 45 steel. When the impact vibration is large, alloy steel such as 55 steel or 40Cr is used.
How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.
