Luxembourg hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder(Luxembourg single rack cylinder,produced by Hengyu Group)
single rack cylinder are widely used in Luxembourg,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed single rack cylinder for customers from Luxembourg.
single rack 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.
The viscosity of the working oil used in the single rack cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
Under normal circumstances, the single rack 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 single rack cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the single rack cylinder and the end cover, the piston and the piston rod, the piston and the single rack 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 single rack cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
When the single rack cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the single rack cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the single rack cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.
The cylinder is moving too fast. I want to slow it down. What can I do?
The hydraulic cylinder is the execution action, and the power source is the hydraulic system. The cylinder speed is too fast, indicating that the system flow is large, the hydraulic system has a hydraulic valve responsible for speed control function, method: 1, by adjusting the speed control valve to reduce the speed; 2, the speed control valve has been adjusted to the lowest, indicating that the hydraulic system design flow is too high, the need to re-configure the hydraulic system according to demand, or the cylinder diameter is changed.
How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
