Bolivia hydraulic cylinder,steering cylinder manufacturer,steering cylinder(Bolivia steering cylinder,produced by Hebei Hengyu company)
steering cylinder are widely used in Bolivia,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed steering cylinder for customers from Bolivia.
The repair method of the steering cylinder: the repair of the steering cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.
The internal leakage of the steering cylinder should be prevented when the steering cylinder is used. The internal leakage of steering cylinder includes the leakage caused by excessive wear of steering 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.
The steering cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the steering cylinder should pay attention to: the operation should be as far away from the steering cylinder as possible, to avoid falling objects, knocking, rubbing the steering cylinder coating. When cleaning the steering cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the steering cylinder when the oil temperature exceeds 70 ° C.
The machining accuracy of the steering cylinder depends on the level of equipment, production technology and testing means. steering cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.
What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!
How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
