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

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

Introduction to track steering cylinder:

When the hydraulic oil is not pumped into the track steering cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the track steering cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

The track steering cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the track steering cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the track steering cylinder wall due to the stiffness and the weight of the parts, causing scars.

How to repair the track steering cylinder body when it is damaged: When the track steering cylinder has trace deformation and shallow tensile marks, the track steering cylinder is repaired by strong honing process. The heavy honing process can repair track steering cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the track steering cylinder can meet the technical requirements.

track steering cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

Answers to some questions about track steering cylinder:

Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.

How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
