We provide Precision Machining Service Customized Turned stainless steel Mechanical Hydraulic cylinder parts.

The bad consequence of the scratch on the inner hole surface of the hydraulic cylinder block and the quick repair method: 1) the material debris extruded from the scratch groove will be embedded into the seal, which may cause new scratch area trace while damaging the working part of the seal during operation.

② The surface roughness of the inner wall of the cylinder is deteriorated, the friction force is increased, and the crawling phenomenon is easy to occur.

③ The internal leakage of hydraulic cylinder is increased, and the working efficiency of hydraulic cylinder is reduced. The main causes of scuffing on the surface of cylinder bore are as follows.

(1) Scars caused by assembling hydraulic cylinder

① Foreign matters mixed into the hydraulic cylinder during assembly cause scars. Before general assembly, all parts must be deburred and cleaned. When installing parts with burr or dirt, foreign matters are easy to be embedded into the surface of cylinder wall due to "strength difference" and self weight of parts.

② When installing the hydraulic cylinder, the piston, cylinder head and other parts have large mass, large size and large inertia. Even with the auxiliary installation of lifting equipment, due to the small specified fit clearance, they will be put into operation in any case. Therefore, when the piston end or cylinder head boss collides with the inner surface of the cylinder wall, it is easy to cause scars. The way to solve this problem is: for the small products with large quantity and large quantity, the autocratic assembly guide tools are used during installation; for heavy, thick, large large and medium-sized hydraulic cylinders, only careful and careful operation can avoid them.

③ When measuring the inner diameter of the cylinder body, the measuring contact is inserted into the hole wall of the cylinder body while rubbing. The measuring contact is mostly made of wear-resistant hard alloy with high hardness. Generally speaking, the slender scratch caused by small depth during measurement is slight, which does not affect the operation accuracy. However, if the size of measuring rod head is not adjusted properly and the measuring contact is embedded in hard line, it will cause more serious scar. To solve this problem, the first is to measure the length of the adjusted measuring head. In addition, a paper tape with a hole only at the measuring position is pasted on the inner surface of the cylinder wall, which will not produce the above-mentioned shape scratches. The slight scratch caused by measurement can be wiped off with the reverse side of old sand cloth or toilet paper.
