Belgium hydraulic cylinder,tilting furnace hydraulic cylinder manufacturer,tilting furnace hydraulic cylinder(Belgium tilting furnace hydraulic cylinder,produced by Hengyu Group)
tilting furnace hydraulic cylinder are widely used in Belgium,because of no need for deceleration device,high work efficiency,excellent fatigue and impact resistance.So our company has designed tilting furnace hydraulic cylinder for customers from Belgium.
The tilting furnace hydraulic cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the tilting furnace hydraulic cylinder, bite. Elimination method: When installing the tilting furnace hydraulic cylinder, ensure that the axis position of the tilting furnace hydraulic cylinder is consistent with the direction of movement; Make the load borne by the tilting furnace hydraulic cylinder as far as possible through the tilting furnace hydraulic cylinder axis, to avoid the phenomenon of eccentricity.
Under normal circumstances, the tilting furnace 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 tilting furnace hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the tilting furnace hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the tilting furnace 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 tilting furnace hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
If the tilting furnace hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the tilting furnace hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow tilting furnace hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the tilting furnace hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the tilting furnace hydraulic cylinder includes the leakage caused by excessive wear of the tilting furnace hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and tilting furnace hydraulic cylinder, and the phenomenon of "pulling the tilting furnace hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.
When the tilting furnace hydraulic 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 tilting furnace hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the tilting furnace hydraulic 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.
What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.
What is the valve on the hydraulic cylinder?
Oil valve, relief valve, overload valve, explosion-proof valve, etc., these are very convenient to insert! The oil valve, the overload valve and the blasting valve are very important for larger cylinders. Manufacturers will not offer you the selection. You need to choose the values by yourself according to your system, pump, cylinder, environment, working conditions and other comprehensive consideration!
