retractable cylinder are widely used in France，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed retractable cylinder for customers from France.

Introduction to retractable cylinder:

Repair method of small range wear of oil retractable 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.

The internal leakage of the retractable cylinder should be prevented when the retractable cylinder is used. The internal leakage of retractable cylinder includes the leakage caused by excessive wear of retractable 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 installing the retractable cylinder pipe, the pipe should be cleaned after installation, and should not pass through the retractable cylinder block, and the by-pass pipe must be installed in front of the oil port of the retractable cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the retractable cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the retractable cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

At the rated pressure, the thrust of the retractable cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the retractable cylinder is related to the diameter of the retractable cylinder, but not to the stroke of the retractable cylinder. Moreover, the larger the retractable cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the retractable cylinder.

Answers to some questions about retractable cylinder:

When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.
