(Sri Lanka steering power cylinder,produced by Hengyu Group）

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

Introduction to steering power cylinder:

The coordination of the sliding parts of the steering power cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

When the steering power cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the steering power cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

How to determine the working pressure of the steering power cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, steering power cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

Do not regularly check the damage of the chrome layer of the steering power cylinder: completely extend the steering power cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the steering power cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the steering power cylinder seal. Welding slag is strictly prohibited on the surface of the steering power cylinder.

Answers to some questions about steering power cylinder:

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.

How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
