1. is it necessary to check the cylinder seal before installation? If it is to be carried out, what are the specific ones?
The inspection of cylinder seals before installation is necessary from a professional point of view, so the answer to question 1 is necessary. Because, if not, once the problem, will affect the sealing effect of the seal, as well as the normal use of the cylinder, so careless. And in the specific content, mainly depends on whether the seal quality problems, as well as its size, whether it meets the use requirements.
2. how can the oil cylinder seal be passed through the oil hole?
Cylinder seals, if it has been through the oil hole, in fact, it is very simple, just the cylinder bore diameter and the oil hole through the connection, grinding into a circular arc, and in the installation, on the top of a suitable amount of lubricant, then, you can successfully complete the work. Moreover, it can avoid the problem of pulling or damaging seals.
3. if it is a low pressure hydraulic cylinder, which kind of cylinder seal should be selected? In addition, can the cylinder seal determine the cylinder coaxiality?
In the low-pressure hydraulic cylinder, in the specific types of cylinder seals, generally speaking, is the choice of O-ring, in the material, it can be for fluororubber and so on, as for the reason, it is because of its good sealing effect. In question 2, the answer is no, because there is no relationship between cylinder seals and cylinder coaxiality, so, there is no such saying, cylinder coaxiality is the determinant of this one.
