Republic of Lithuania hydraulic cylinder,loading cylinder manufacturer,loading cylinder
(Republic of Lithuania loading cylinder,produced by Hengyu Hydraulic Co., Ltd）
loading cylinder are widely used in Republic of Lithuania，because of no need for deceleration device，long service life，smooth movement.So our company has designed loading cylinder for customers from Republic of Lithuania.
The meaning of the loading cylinder model marked by the loading cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the loading cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the loading cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
In the case of serious wear on the inner surface of the loading cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the loading cylinder manufacturing process for replacement. The loading cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.
Repair method of small range wear of oil loading cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.
When the piston speed of the loading cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the loading cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.
Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
