What's the impact of the piston on the impactor?
Aug 31, 2017

As we all know, impactor is a kind of drilling equipment which needs to be used. It is generally divided into pneumatic and hydraulic, which is convenient and flexible in use. Among them, piston is an important component of the impactor. What is the impact of the piston on the impactor?

The piston is the main moving part of the impactor. It has relative movement with the cylinder, the guide sleeve and the valve rod. Throughout the work cycle, the piston contacts and guides the bore inside the cylinder, but is in contact with the guide sleeve and the valve rod, and sometimes leaves. Therefore, manufacturers in the production should pay attention to the following points.

1.The clearance between the piston head and the cylinder block of the impactor shall be smaller than the piston rod and guide sleeve. 

2.piston and internal clearance is too large, front and rear cylinder will leak, affecting efficiency.

3, the gap is too small, it will easily stuck or abrasions. Therefore, it is a crucial step for manufacturers to pay attention to the gap between them.
