Argentina hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder(Argentina stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stroke adjustable cylinder are widely used in Argentina,because of no transmission clearance,simple structure and reliable operation,excellent temperature resistance.So our company has designed stroke adjustable cylinder for customers from Argentina.
When the initial action of the stroke adjustable cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the stroke adjustable cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.
When the stroke adjustable cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the stroke adjustable cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.
The scar on the sliding surface of the stroke adjustable cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the stroke adjustable cylinder wall. Therefore, before installation, these scars must be fully repaired.
The coordination of the sliding parts of the stroke adjustable cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.
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!
