This article mainly introduces:
Colombia hydraulic cylinder,servo hydraulic cylinder manufacturer,servo hydraulic cylinder(Colombia servo hydraulic cylinder,produced by Hebei Hengyu company)
servo hydraulic cylinder are widely used in Colombia,because of no need for deceleration device,excellent fatigue and impact resistance,excellent temperature resistance.So our company has designed servo hydraulic cylinder for customers from Colombia.
In the process of using the servo hydraulic cylinder, sometimes such a problem will occur, the servo hydraulic cylinder can not act immediately after the instruction of the servo hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil servo hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.
servo hydraulic cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.
Under normal circumstances, the servo hydraulic 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 servo hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the servo hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the servo hydraulic 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 servo hydraulic 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 servo hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the servo hydraulic cylinder, causing damage to the seal and causing leakage in the servo hydraulic 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.
When does the cylinder rotate?
The piston rod inside the multistage plunger cylinder can be rotated, and it will rotate when it is subjected to tangential force.
What hydraulic valve is used to control a cylinder back and forth?
Direction valve is available. Direction valve includes electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve, the specific choice of which direction valve, you need to see the use of conditions.
