(Tunisia folding machine cylinder,produced by Hengyu Hydraulic Cylinder Factory）

folding machine cylinder are widely used in Tunisia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed folding machine cylinder for customers from Tunisia.

Introduction to folding machine cylinder:

folding machine cylinder can not drive the load troubleshooting: oil pressure is too low. folding machine cylinder selection specifications are too small. Leakage in folding machine cylinder or associated hydraulic system element.

The folding machine cylinder should be used correctly and maintained regularly. The folding machine cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the folding machine cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

When producing oil folding machine cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

When the folding machine cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the folding machine cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

Answers to some questions about folding machine cylinder:

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.
