Characteristics of ZRC5A-DHD350 impactor
|
1. Mainly used in ground source, water well market and mine mining that require drilling operations above 135mm.
|
2. The matching drill bit does not require a nylon tail tube, so it saves the trouble caused by the fracture, damage and thermal expansion and contraction of the nylon tail tube;
|
3. The impact energy loss is low, the impact frequency is high, and the drilling speed is 15%-20% faster than the same type of impactor with tail pipe;
|
4. Low air consumption, saving wind and fuel, saving more than 10% fuel than the same type with tailpipe impactor;
|
5. The internal structure is simple and reasonable, and the maintenance is convenient; the parts have good consistency, high reliability, low overall failure rate, low disassembly frequency, long impact life, and low use cost.
