(America track steering cylinder,produced by Hengyu Hydraulic Co., Ltd）

track steering cylinder are widely used in America，because of no need for deceleration device，smooth movement，long service life.So our company has designed track steering cylinder for customers from America.

Introduction to track steering cylinder:

If the seal of the track steering cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and track steering cylinder, and the phenomenon of "pulling the track steering cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Do not enter foreign bodies when installing the track steering cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

The definition of the minimum starting pressure of the track steering cylinder refers to the minimum working pressure of the track steering cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the track steering cylinder parts and the size of the sealing friction.

There are some honeycomb holes in the inner wall of the track steering cylinder, piston or piston rod surface. How is this formed? When we repair the track steering cylinder, we can see that there are some honeycomb holes on the inner wall of the track steering cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the track steering cylinder is targeted to prevent. Is very necessary.

Answers to some questions about track steering cylinder:

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.

Servo cylinder control principle
The electro-hydraulic pulse servo cylinder is composed of a stepper motor, a three-position four-way servo valve, a mechanical feedback device (a wire carrier) and an oil lever. When the stepper motor gets a pulse signal, its output shaft rotates 1.5 or 3 degrees, the servo valve spool drives the wire to rotate at the same time, the valve spool moves and opens the reversing cylinder to output pressure oil, the piston moves and drives the lead screw to reverse rotate the valve spool back to the original position, and the servo valve stops output pressure oil in the center. At this time, the cylinder moves 0.1 or 0.2mm stroke, and the displacement and speed of the cylinder travel are determined according to the given value of the electrical pulse.
