(Spain single rack cylinder,produced by Hengyu Group）

single rack cylinder are widely used in Spain，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed single rack cylinder for customers from Spain.

Introduction to single rack cylinder:

The material of the sliding part of the single rack cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

If the single rack cylinder slips or crawls, please check whether there is astringency inside the single rack cylinder, because the internal parts of the single rack cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the single rack cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the single rack cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

In use, the single rack cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the single rack cylinder.

Before the single rack 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.

Answers to some questions about single rack cylinder:

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.
