6"High Air Pressure DTH Hammers QL60 Down Hole for rock drilling,water well,mining
Features:
- Valveless operation to maximize energy output, provide efficient air utilitzation and reduce service requirements
- Extra air-flow system allows for better hole cleaning in troublesome holes
- Reversible hardened wear sleeve for optimum wear resistance even in the most abrasive conditions
- Multi-start threads on back head and chuck ensure easy coupling/uncoupling of hammer
- Unique internal mount system gives positive make-up and eliminates the need for wear shims and special assembly tools
- All critical internal components are heat treatedunder strict control to maximize tool longevity
- An overall cost-effective and user-friendly tool for use in the most demanding conditions
The Characteristics of High Air Pressure DTH Hammers With Foot Valve:
It is a kind of valveless high air pressure DTH hammer with foot valve. It has the following advantages:
The main features are as following:
1. Valveless air distribution, more reliable.
2. Simple design of the piston. Long life span.
3. More efficient energy transfer, faster drilling speed, low air consumption and lower oil consumption.
4. Fewer internal parts, simple structure, long life span, less failure and easier to maintain because all the parts are heat treated.
5. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multiple steps thread.
