Switzerland hydraulic cylinder,stacker cylinder manufacturer,stacker cylinder(Switzerland stacker cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stacker cylinder are widely used in Switzerland,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed stacker cylinder for customers from Switzerland.
How to repair the stacker cylinder body when it is damaged: When the stacker cylinder has trace deformation and shallow tensile marks, the stacker cylinder is repaired by strong honing process. The heavy honing process can repair stacker cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the stacker cylinder can meet the technical requirements.
stacker 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.
If it is found that the stacker cylinder lubrication is poor or the stacker cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the stacker cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the stacker cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the stacker cylinder center line. In this way, when the piston works in the stacker cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the stacker cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
The internal leakage of the stacker cylinder is an important indicator to measure the quality of the stacker cylinder: the internal leakage of the stacker cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the stacker cylinder, so that the stacker cylinder can not accurately and stably stop in a certain position of the stacker cylinder, so it is one of the main indicators of the stacker cylinder.
Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).
How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
