Cote d 'Ivoire trailer hydraulic cylinder,trailer hydraulic cylinder manufacturer
(Cote d 'Ivoire trailer hydraulic cylinder,produced by Hengyu Group）
trailer hydraulic cylinder are widely used in Cote d 'Ivoire，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed trailer hydraulic cylinder for customers from Cote d 'Ivoire.
The method of sleeve trailer hydraulic 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 trailer hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the trailer hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
When purchasing the trailer hydraulic cylinder, try to clarify the following parameters of the trailer hydraulic cylinder: A. trailer hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or trailer hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right trailer hydraulic cylinder type can be found accurately and quickly.

trailer hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the trailer hydraulic cylinder is placed for a period of time, the trailer hydraulic cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.
What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.
Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.
