(Saudi Arabia single rack cylinder,produced by Hengyu Group）

single rack cylinder are widely used in Saudi Arabia，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed single rack cylinder for customers from Saudi Arabia.

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.

When installing the single rack cylinder, the axial ends of the single rack cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the single rack cylinder, there is axial expansion. If the two ends of the single rack cylinder are fixed, all parts of the single rack cylinder will be deformed. When disassembling the single rack cylinder, it is strictly forbidden to hammer the single rack cylinder and the piston surface, such as the single rack cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

The difference between the plunger single rack cylinder and the piston single rack cylinder is that the piston in the single rack cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type single rack cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

single rack cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the single rack cylinder is placed for a period of time, the single rack cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

Answers to some questions about single rack cylinder:

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.
