The manufacture and difference of mine balanced non pressure damper and mine forward and reverse dampe

 
The manufacture and difference of mine balanced non pressure damper and mine forward and reverse damper do you want to know the manufacture and difference between mine balanced non pressure damper and mine forward and reverse damper? Don't worry, I'll explain it to you one by one! In fact, there is no difference in the manufacturing process between the mining balanced non pressure damper and the mining forward and reverse damper
They are both mining dampers
They are all non pressure dampers
There is no difference in the manufacturing process, whether in welding or blanking;
If there are differences, their principles and composition are different
Basically, there are two sets of balanced non pressure dampers for mining, forming a unified individual for use; The positive and negative dampers of coal mines are generally a set of four, consisting of two positive and two negative dampers, which is equivalent to four dampers can be used as a whole; Of course, there are also different principles
A set of mining forward and reverse dampers is equivalent to two sets of mining balanced non pressure dampers
Therefore, there are a lot of balanced non pressure dampers used in mining, and there are not many positive and negative dampers used in mining
