(Belarus steering cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to steering cylinder:

steering cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards steering cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the steering cylinder guide is determined by the length of the stroke. Check the strength of steering cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

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.

When the steering cylinder is installed, the piston and the steering cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the steering cylinder head boss is easy to cause scars when it hits the inner surface of the steering cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized steering cylinders, only careful and careful operation can be avoided.

steering cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the steering cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

Answers to some questions about steering cylinder:

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder 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 cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent 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 cylinder can be improved.

What causes hydraulic cylinder oil leakage?
1. Internal leakage (1) The wear ring on the piston is seriously worn, leading to friction between the piston and the cylinder liner, and finally strain the cylinder liner, piston and seal; 2) Seal long-term use failure, piston seal (mostly U, V, Y ring, etc.) aging; 3) The hydraulic oil is dirty, and a large number of impurities enter the cylinder and wear the piston seal to bad; 2. External leakage 1) cylinder inlet and outlet tubing joint cracking; (This I see in the actual work is still more) 2) The piston rod extension end with the piston rod seal damage, mostly due to the piston cylinder is caused by hair, but also caused by aging; 3) The seal between the extended end of the piston rod and the liner is damaged.
