GK 200 Soil Testing Drilling Rig Introduction

GK200 Core drilling rig is a kind of core drilling equipment, which is mainly used for the general survey and exploration of metal and non-metallic solid minerals. In addition, it can also be used for engineering geological exploration, hydrogeological investigation, general survey and exploration of oil and gas fields, water well drilling, etc. Since the core drilling rig requires to take out relatively complete formation rock samples without mixing and non deflection, the core drilling rig is a rotary drilling rig.gk 200 core drilling rig is mainly used for underground drilling of gas drainage (drainage) holes, water exploration holes, grouting fire extinguishing holes, coal seam water injection holes, outburst prevention and pressure relief holes, geological exploration holes and other engineering holes. It is applicable to various coal seams and rock formations with rock firmness coefficient f ≤ 10. The drill can drill arbitrarily within the azimuth and inclination range specified in the basic parameter table

GK 200 Drilling Rig Technical Data

Precautions during assembly and disassembly of coring rig:

a. During component disassembly, the locating pin shall be removed first and then other disassembly work shall be carried out. During installation, the locating pin shall be installed first after the position is aligned, and then other parts shall be installed.

b. Protect the joint when removing the oil pipeline.

c. The disassembly times of oil pipeline joints shall be minimized to avoid oil leakage.

d. During disassembly and installation, it is forbidden to strike the casting with force. When it is necessary to strike other accessories, wooden blocks or red copper blocks shall be padded

e. Before installation, the parts shall be cleaned with kerosene and coated with sufficient lubricating oil (or grease). The powder metallurgy shaft sleeve shall be carried out according to the provisions in the section of "use and maintenance".

f. Replace damaged or worn parts

g. When installing the diesel engine, pay attention to check the coaxiality of the crankshaft and the worm.

How about the features of it ?

1. With hydraulic automaatic feeding device, elevated drilling efficiency.

2. Large torque and drilling diameter.

3. With a spherial jaw holding mechanism and the rod replacement without breakdwn, high efficiency.

4. Compact structure, small volume, lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas.

5. Adoping large drive pipe, double guide rod, increase the stability.
