(Germany steering cylinder,produced by Hengyu Hydraulic Cylinder Factory）

steering cylinder are widely used in Germany，because of excellent fatigue and impact resistance，no need for deceleration device，excellent temperature resistance.So our company has designed steering cylinder for customers from Germany.

Introduction to steering cylinder:

steering cylinder is the most important part of construction machinery, the traditional processing method is: broaching steering cylinder block - fine boring steering cylinder block - grinding steering cylinder block. The rolling method is: broaching steering cylinder block - fine boring steering cylinder block - rolling steering cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the steering cylinder block is about 1-2 days, rolling 1 meter of the steering cylinder 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 RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, 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 steering cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality steering cylinders, you must take the rolling production process. After the steering cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

steering cylinder piston rod material introduction: In general, we use 45 steel to produce steering cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

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

After the steering cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

Answers to some questions about steering cylinder:

What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.

What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.
