Belarus hydraulic cylinder,hinge shaft cylinder manufacturer,hinge shaft cylinder(Belarus hinge shaft cylinder,produced by Hengyu Group)
hinge shaft cylinder are widely used in Belarus,because of long service life,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed hinge shaft cylinder for customers from Belarus.
Disassembly hinge shaft cylinder: When disassembly hinge shaft cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the hinge shaft cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the hinge shaft cylinder.
When the hinge shaft cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the hinge shaft cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.
Regular maintenance of the hinge shaft cylinder includes: regular tightening, hinge shaft cylinder fastening screws and gland screws, hinge shaft cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the hinge shaft cylinder once a year. Clean regularly, the hinge shaft cylinder is cleaned every other year, and the seals are replaced while cleaning.
How to repair the hinge shaft cylinder body when it is damaged: When the hinge shaft cylinder has trace deformation and shallow tensile marks, the hinge shaft cylinder is repaired by strong honing process. The heavy honing process can repair hinge shaft 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 hinge shaft cylinder can meet the technical requirements.
What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.
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.
