(Canada reset cylinder,produced by Hengyu Group）
reset cylinder are widely used in Canada，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed reset cylinder for customers from Canada.
The "O" ring can be used as an auxiliary seal inside the reset cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the reset cylinder, and can be completely sealed.
After chrome plating of the piston rod of the reset 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.
Under normal circumstances, the reset cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the reset cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the reset cylinder and the end cover, the piston and the piston rod, the piston and the reset cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the reset cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
The main role of the reset cylinder: the reset cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the reset cylinder realizes reciprocating motion. The structure of the reset cylinder has three categories: piston reset cylinder, plunger reset cylinder, swing reset cylinder, piston reset cylinder and plunger reset cylinder to achieve reciprocating linear motion, output speed and thrust, swing reset cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the reset cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The reset cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
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.
