Not only to hammer hammer to repair
Understand the working principle of electric hammer, hammer check why not rotating hammer is much easier. I saw it yesterday, after simple treatment, hammer returned to normal work, make a concrete wall with easy fix, easy.First of all, I was on the Internet, looking for a "just turn, not hammer maintenance" video, this video is really good, with animation introduced very clearly. I just watched this video and did it myself.
I thought the hammer and hammer is one thing, to know the master said, a family of percussion drill, impact drill, you know you are not telling the impact drill, but hammer. Later on the Internet to check, there is indeed the essential difference between the two work principle is not the same.Although the impact of drilling and hammer are gearing rotation while the driven reciprocating hammer drill, and a direction perpendicular to the drill hammer motion, but the fundamental difference is: the impact drill is composed of a transmission mechanism of direct transmission of reciprocating hammer drill, depends on the interaction between the gear form the impact force to work the hammer, and is driven by a transmission mechanism and a piston in a cylinder of reciprocating air cylinder air pressure cycle drives the cylinder hammer blow in reciprocating drill to work, the brand specific structure is different, but the same principle, because there are a set of pneumatic structure, impact hammer general to be much higher than the impact drill.
The hammer is now home in frequently used tools, used to make a wall. Good use for electric hammer is very fast and convenient, not good for half a day, get out of a hole, is very laborious, tired out.I think this is a hammer broken, is the quality problem, superstition foreign hammer so that, in fact the quality of domestic has been passed, as long as the correct use and careful maintenance, hammer together with the effect is very good.
