(Panama track steering cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to track steering cylinder:

When the piston speed of the track steering cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the track steering cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

If the track steering cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the track steering cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow track steering cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the track steering cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the track steering cylinder includes the leakage caused by excessive wear of the track steering cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials 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 operations should be done according to the installation instructions.

Causes and countermeasures of oil track steering cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the track steering cylinder will lead to premature wear of the piston seal, replace the piston seal; If the track steering cylinder is visibly scarred, the track steering cylinder must be replaced. It can be pressurized at one end of the track steering cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most track steering cylinder piston drift may not come from the track steering cylinder, the above method to determine the track steering cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

The track steering cylinder is mainly composed of body, piston, piston rod, track steering cylinder head, track steering cylinder bottom, piston rod head and related auxiliary devices. The piston divides the track steering cylinder into two chambers, and moves reciprocally in the track steering cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the track steering cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the track steering cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the track steering cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the track steering cylinder bottom and the track steering cylinder head is serious, so the buffer deceleration should be set at both ends of the track steering cylinder The working medium of the track steering cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; track steering cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the track steering cylinder: The buffer structure of the track steering cylinder is to prevent the piston from colliding with the track steering cylinder head at the end of the stroke.

Answers to some questions about track steering cylinder:

What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.

How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
