Ireland hydraulic cylinder,sanitation truck hydraulic cylinder manufacturer,sanitation truck hydraulic cylinder(Ireland sanitation truck hydraulic cylinder,produced by Hebei Hengyu company)
sanitation truck hydraulic cylinder are widely used in Ireland,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed sanitation truck hydraulic cylinder for customers from Ireland.
We can not just consider the price and ignore the quality when we purchase the sanitation truck 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 sanitation truck 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 sanitation truck hydraulic cylinder is not required.
When installing the sanitation truck hydraulic cylinder, the axial ends of the sanitation truck hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the sanitation truck hydraulic cylinder, there is axial expansion. If the two ends of the sanitation truck hydraulic cylinder are fixed, all parts of the sanitation truck hydraulic cylinder will be deformed. When disassembling the sanitation truck hydraulic cylinder, it is strictly forbidden to hammer the sanitation truck hydraulic cylinder and the piston surface, such as the sanitation truck hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
The material of the sliding part of the sanitation truck hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
The sanitation truck 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 sanitation truck hydraulic cylinder, bite. Elimination method: When installing the sanitation truck hydraulic cylinder, ensure that the axis position of the sanitation truck hydraulic cylinder is consistent with the direction of movement; Make the load borne by the sanitation truck hydraulic cylinder as far as possible through the sanitation truck hydraulic cylinder axis, to avoid the phenomenon of eccentricity.
Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
