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

Introduction to steering power cylinder:

steering power cylinders in series, parallel and series parallel. Series: In the steering power cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the steering power cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the steering power cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the steering power cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

The piston rod and guide sleeve function of the steering power cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

The steering power cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the steering power 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 steering power cylinder wall due to the stiffness and the weight of the parts, causing scars.

steering power cylinder installation precautions: Before installing the steering power cylinder into the system, the parameters on the steering power cylinder label should be compared with the parameters when ordering. The base of the steering power cylinder must have sufficient stiffness, otherwise the steering power cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

Answers to some questions about steering power cylinder:

How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.

What are the causes of hydraulic cylinder oil leakage?
First, between the piston rod and the guide sleeve: 1, the cylinder force is not good, there is a radial force between the piston rod and the guide sleeve there is a partial load, so that the oil seal is worn early, causing oil leakage. 2. The ambient temperature of the piston rod is high, especially radiant heat, and the oil seal aging is fast. 3. Whether the oil seal is selected correctly; Check whether the oil seal is damaged during installation. 4, guide sleeve and piston rod matching tolerance is correct. Second, between guide sleeve and cylinder: 1. Whether the O-ring on the guide sleeve is installed correctly, pay special attention to the O-ring can not "roll", especially some O-rings are die-pressed with a die-closing line. Third, common problems: 1, guide sleeve, cylinder, piston rod concentricity is poor. Fit tolerance is correct.
