Libya hydraulic cylinder,tension cylinder manufacturer,tension cylinder
(Libya tension cylinder,produced by Hebei Hengyu company）
tension cylinder are widely used in Libya，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed tension cylinder for customers from Libya.
Factors that should be considered when selecting the oil seal in the tension cylinder: some specific factors should be taken into account when selecting the oil seal in the tension cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: tension cylinder diameter, piston rod diameter, piston rod and piston groove size, tension cylinder working pressure, tension cylinder movement speed, hydraulic system oil temperature and tension cylinder working environment.
Before the tension cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.
tension cylinder can not drive the load troubleshooting: oil pressure is too low. tension cylinder selection specifications are too small. Leakage in tension cylinder or associated hydraulic system element.
The piston rod of the tension cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.
The two cylinders of the bending machine are out of sync?
Check whether the sliding slide is worn, adjust its tightness, so that both sides are consistent, check whether the two cylinder tubing is connected, tighten the flow valve, pressure, let the cylinder air discharge.
What causes hydraulic cylinder oil leakage?
1. Internal leakage (1) The wear ring on the piston is seriously worn, leading to friction between the piston and the cylinder liner, and finally strain the cylinder liner, piston and seal; 2) Seal long-term use failure, piston seal (mostly U, V, Y ring, etc.) aging; 3) The hydraulic oil is dirty, and a large number of impurities enter the cylinder and wear the piston seal to bad; 2. External leakage 1) cylinder inlet and outlet tubing joint cracking; (This I see in the actual work is still more) 2) The piston rod extension end with the piston rod seal damage, mostly due to the piston cylinder is caused by hair, but also caused by aging; 3) The seal between the extended end of the piston rod and the liner is damaged.
