Croatia hydraulic cylinder,punch machine hydraulic cylinder manufacturer,punch machine hydraulic cylinder
(Croatia punch machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
punch machine hydraulic cylinder are widely used in Croatia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed punch machine hydraulic cylinder for customers from Croatia.
punch machine hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the punch machine hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the punch machine hydraulic cylinder. c. The punch machine hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the punch machine hydraulic cylinder seal, replace the punch machine hydraulic cylinder seal.
The internal leakage of the punch machine hydraulic cylinder should be prevented when the punch machine hydraulic cylinder is used. The internal leakage of punch machine hydraulic cylinder includes the leakage caused by excessive wear of punch machine hydraulic 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.
When the control pressure of the hydraulic system is too low, the punch machine hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
In order to ensure the service life of the punch machine hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.
What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.
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!
