New design diamond core drill rig for sale

Product Description

I. General intrudution

DF-Y-4 Core Drill is a new type high speed diamond core drill, designed according to the development of geological work in China and developed to meet the requirements of clients.

DF-Y-4 Core Drill has been identified in 1976, and rewarded with the Chinese National Silver Medal in 1988. The DF-Y-4model has been sold all over the country.

DF-Y-4 Core Drill can be driven by Deutz F4L 912 diesel engine or Weichai diesel engine or 30KW electric motor. The drill has 8 rotary speed stage, the Max, speed 1588 rpm, the min speed 101 rpm, so it is suitable for various drilling for solid mineral deposits with diamond or tungsten-carbide tipped bit.

It is also suitable for engineering geological subterranean water explorations as well as explorations of shallow layer oil and natural gas, and can be used to drill holes for ventilation and drainage of main

Gallery.

II. Main Features

1. The rig is in higher rotational speed and rational range of rotational speed; large torque in low speed.

2. The drill is suitable in the mountain area because of light weight for easy transport and convenient dis assembly (to be disassembled into nine parts).

3. With compact structure and reasonable layout, and all exposed,non overlapped components, it is easier for maintenance and repair.

4. It is convenient for you to treat trouble with two reverse speeds. With low center of gravity, the rig is reliable and stable in high speed drilling.

5. The operation levers are concentrated, so the operations are reliable and convenient.

6. Fitted with meters, the circumstances can be controlled easily in hole.

7. The transmission is separately driven for drill rig and mud pump; it is easier for the location arrangement with less space occupying.
