Ghana hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder(Ghana single rack cylinder,produced by Hengyu Group)
single rack cylinder are widely used in Ghana,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed single rack cylinder for customers from Ghana.
How to repair the single rack cylinder body when it is damaged: When the single rack cylinder has trace deformation and shallow tensile marks, the single rack cylinder is repaired by strong honing process. The heavy honing process can repair single rack 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 single rack cylinder can meet the technical requirements.
The internal leakage of the single rack cylinder should be prevented when the single rack cylinder is used. The internal leakage of single rack cylinder includes the leakage caused by excessive wear of single rack cylinder block seal, piston rod and seal cover seal and 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.
single rack cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the single rack cylinder is placed for a period of time, the single rack cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.
The method of sleeve single rack cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the single rack cylinder can be significantly improved by rolling in the finishing of the inner holes of the single rack cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.
