(S.Africa steering cylinder,produced by Hengyu Group）

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

Introduction to steering cylinder:

What kind of process is used in the steering cylinder to make high-quality steering cylinder products: the body is the main component of the steering cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The steering cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the steering cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the steering cylinder increases by 25%. If the service life of the steering cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. steering cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the steering cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and steering cylinder are stuck or the steering cylinder is blocked. At this time, no matter how to manipulate, the steering cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the steering cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

At the rated pressure, the thrust of the steering cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the steering cylinder is related to the diameter of the steering cylinder, but not to the stroke of the steering cylinder. Moreover, the larger the steering cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the steering cylinder.

The material, shape and compression of the steering cylinder seal have a great impact on the service life and work efficiency of the steering cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

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

Answers to some questions about steering cylinder:

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.

How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.
