(Bolivia steering power cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to steering power cylinder:

When the initial action of the steering power cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the steering power cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

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

If the steering power 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 steering power cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow steering power cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the steering power cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the steering power cylinder includes the leakage caused by excessive wear of the steering power 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 steering power cylinder, and the phenomenon of "pulling the steering power cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The steering power cylinder is mainly composed of body, piston, piston rod, steering power cylinder head, steering power cylinder bottom, piston rod head and related auxiliary devices. The piston divides the steering power cylinder into two chambers, and moves reciprocally in the steering power 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 steering power cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the steering power 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 steering power 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 steering power cylinder bottom and the steering power cylinder head is serious, so the buffer deceleration should be set at both ends of the steering power cylinder The working medium of the steering power cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; steering power 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 steering power cylinder: The buffer structure of the steering power cylinder is to prevent the piston from colliding with the steering power cylinder head at the end of the stroke.

Answers to some questions about steering power cylinder:

Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.
