(France track steering cylinder,produced by Hebei Hengyu company）

track steering cylinder are widely used in France，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed track steering cylinder for customers from France.

Introduction to track steering cylinder:

When producing oil track steering 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.

The difference between the integral track steering cylinder and the split track steering cylinder: The integral track steering cylinder and the split track steering cylinder in the track steering cylinder are two different track steering cylinders, and they are very different. The whole track steering cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split track steering cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and track steering cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

The track steering cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the track steering cylinder, bite. Elimination method: When installing the track steering cylinder, ensure that the axis position of the track steering cylinder is consistent with the direction of movement; Make the load borne by the track steering cylinder as far as possible through the track steering cylinder axis, to avoid the phenomenon of eccentricity.

The piston rod of the track steering cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Answers to some questions about track steering cylinder:

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
