Germany hydraulic cylinder,land leveller hydraulic cylinder manufacturer,land leveller hydraulic cylinder(Germany land leveller hydraulic cylinder,produced by Hengyu Group)
land leveller hydraulic cylinder are widely used in Germany,because of long service life,smooth movement,high work efficiency.So our company has designed land leveller hydraulic cylinder for customers from Germany.
When the land leveller 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 land leveller hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the land leveller 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.
We can not just consider the price and ignore the quality when we purchase the land leveller hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the land leveller hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the land leveller hydraulic cylinder is not required.
The land leveller hydraulic cylinder should be used correctly and maintained regularly. The land leveller hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the land leveller hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
The difference between the integral land leveller hydraulic cylinder and the split land leveller hydraulic cylinder: The integral land leveller hydraulic cylinder and the split land leveller hydraulic cylinder in the land leveller hydraulic cylinder are two different land leveller hydraulic cylinders, and they are very different. The whole land leveller hydraulic cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split land leveller hydraulic cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and land leveller hydraulic cylinder damage. Therefore, it is obvious that the answer to this question is for difference.
About the hydraulic cylinder wall thickness problem?
Hydraulic cylinder wall thickness calculation formula: t=PD/200St= pipe wall thickness (minimum thickness) mmP= maximum pressure kg/cm2? d= inner diameter mm? S=δ/5 safety factor δ= minimum tensile strength This case: set the cylinder material 45#, tensile strength 58kg/cm2t=(640X40)/(200X11.6)t=11mm piston output (i.e. Thrust) calculation formula: F1=PD2X(3.14/4)F1=640X42X0.785=8,038kg Note: Square numbers will not be used, all 2's in the text are square codes.
How to remove the lifting cylinder from the forklift truck?
The lifting cylinder is generally fixed on the door frame, and there are screws under and above it, and it is OK to loosen the screws with a wrench on the top. However, we must pay attention to ensure safety and prevent damage to the cylinder or safety accidents.
