steering power cylinder are widely used in Portugal，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed steering power cylinder for customers from Portugal.

Introduction to steering power cylinder:

steering power cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the steering power cylinder is placed for a period of time, the steering power cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

When installing the steering power cylinder, the axial ends of the steering power cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the steering power cylinder, there is axial expansion. If the two ends of the steering power cylinder are fixed, all parts of the steering power cylinder will be deformed. When disassembling the steering power cylinder, it is strictly forbidden to hammer the steering power cylinder and the piston surface, such as the steering power cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

When the steering power cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

When the steering power cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the steering power cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the steering power cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about steering power cylinder:

What is a hydraulic cylinder assembly?
Assembly, which means aggregate. A series of parts or products, formed to achieve a specific function of the whole, the general term for this system is assembly. The hydraulic cylinder assembly is not a single hydraulic cylinder part, which can be used by connecting the hydraulic hose.

What is the difference between hollow and solid oil cylinders?
Hollow solid cylinder, according to conventional understanding, refers to whether the piston rod is solid or hollow. General ordinary hydraulic cylinder, the piston rod is solid structure. Hollow hydraulic cylinder refers to a hollow piston rod structure of the hydraulic cylinder, see the attached figure. Piston rod hollow function: 1, the piston rod hollow, the middle can be threaded rod. For example, the clamping cylinder with a sawing machine, the piston rod center threading rod, part of the stroke through manual, part of the stroke hydraulic automatic walk. 2, the hollow hole of the piston rod can be used to direct the oil circuit to achieve special oil circuit. 3, the cylinder is relatively large, the piston rod is relatively large, and the stroke is longer, in this case, the piston rod is hollow to reduce the movement friction and lateral force.
