The cause of the wound caused by the hydraulic cylinder in the assembly

What are the causes of the wound in the assembly of hydraulic cylinder:

Installation parts in the scars of the hydraulic cylinder installation, piston and cylinder head and other parts quality, large size, large inertia, even with auxiliary hoisting equipment installation, due to regulations with the gap is very small, no matter how will don't fresh investment. Therefore, the piston end or head convex in the bump wall surface, easily caused by scars. Methods to solve this problem: for a large number of small products, the installation of the use of an authoritarian assembly oriented tool; the heavy, thick, large and medium-sized hydraulic cylinder, only meticulous, careful operation can be avoided.

Instrument for measuring contact caused by scars usually adopts inner diameter dial indicator measuring inner diameter of the cylinder, measuring contact is edge side friction in wall of cylinder body of people, measuring contact is made of high hardness wear-resistant hard alloy. Generally speaking, when the measurement is not caused by the depth of the elongated shape of the scratch is minor, does not affect the operating accuracy, but if the measurement of rod head size is not adjusted, measuring contact hard line, will cause more severe damage. The countermeasures to solve this problem, first of all is to measure the length of the measuring head for regulating the degree. In addition, a only position measurement in open hole paper tape, paste on the cylinder surface, that will not produce the shape of scratches. Slight scratches caused by measurement, generally worn cloth opposite or strawboard can be wiped.

Assembly when mixing with foreign body caused by scar hydraulic cylinder in front of the general assembly, all parts must be sufficient to remove burrs and wash, parts with burr or dirt to install, due to the weight of "don't trouble" and parts, foreign matter embedded on the surface of the cylinder wall, causing injuries.
