Mainly used for drilling water wells, monitoring wells, geothermal air condition ing hole construction, national defense projects,anti-floating anchor rod,cable anchor rod,high-pressure Rotary Jet Drilling Operations;At the same time, it is suitable for large diameter vertical hole construction in geotechnical engineer- ing such as hydropower station,railway,highway and city foundation, grouting reinforcement hole, small foundation pile holemicro-pile etc..
Construction Features:
1.The power head of drilling rig can change speed both mechanically and hydraulically. Suitable for down-hole Hammer,eel pipe, full casing and alloy rotary drilling methods.
2.Two large cylinders on the mast, lifting force up to 25 tons, eccentric with pipe drilling can be used to pull out casing,but also for small-scale non-excavation construction.
3.The rig uses inside and outside telescopic mast power head travel up to 7 meters, can drill 23 meters drill pipe at a time, reduce a time to add drill pipe, improve efficiency twice.

**FAQs:**
Q: Can water be pumped through my blower?
A: No, only clean and dry air is suitable.
Q: My blower is leaking around the cover—is this normal?
A: Standard blowers are not leak-proof, but we can provide a customized leak-proof version if needed.
Q: What kind of oil do I need for my blower?
A: Our blowers are oil-free and maintenance-free by design.
Q: Can I pump combustible gas through my blower?
A: For such applications, we recommend our explosion-proof ATEX blower (customizable).
Q: Are the foam pieces inside my blower for filtration?
A: No, they are for sound reduction. An inlet filter should be added separately.
Q: What will happen if I don't use a relief valve on my blower?
A: Without a relief valve, the blower may overheat, leading to thermal expansion and potential damage to the impeller and bearings.
