(Greece automobile tailboard cylinder,produced by Hengyu Hydraulic Cylinder Factory）
automobile tailboard cylinder are widely used in Greece，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed automobile tailboard cylinder for customers from Greece.
Under normal circumstances, the automobile tailboard 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 automobile tailboard cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the automobile tailboard cylinder and the end cover, the piston and the piston rod, the piston and the automobile tailboard 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 automobile tailboard cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
In order to ensure the service life of the automobile tailboard cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.
The internal leakage of the automobile tailboard cylinder is an important indicator to measure the quality of the automobile tailboard cylinder: the internal leakage of the automobile tailboard cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the automobile tailboard cylinder, so that the automobile tailboard cylinder can not accurately and stably stop in a certain position of the automobile tailboard cylinder, so it is one of the main indicators of the automobile tailboard cylinder.
After the automobile tailboard cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.
How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.
