GY200 Engineering Drilling Rig Description

GY 200 drilling rig is a light multifunctional engineering project prospecting drilling rig..It was designed for geologic structure prospecting of industrial and civil constructions, such as railways, bridges and hydroelectric projects. The drilling machine could also being used for small calibre piling foundation works.

GY200 Engineering Drilling Rig Technical Information

GY200 Engineering Drilling Rig Advantages

1. It has an automatic oil pressure feeding mechanism to improve drilling efficiency and reduce workers' physical labor;
2. The ball clamping mechanism is used to replace the chuck,
3. Equipped with hole bottom pressure gauge to indicate the pressure, which is convenient to master the situation in the hole;
4. The handle is centralized and easy to operate;
5. Compact structure, drilling rig, water pump and diesel engine are installed on one base, occupying a small area of the airport;
6. Light weight, strong decomposability, easy to move, suitable for working in plain or mountainous areas.

7.The drilling rig is suitable for general survey, geophysical exploration, road and building exploration, etc.

8. Alloy, steel sand and steel particle bits can be selected for drilling according to different formations.

9. It can drill sandy clay and bedrock of grade 2-9.

Core Drilling Principle

The principle of core drilling machine is basically the same, and the main components are drilling machine, drill pipe, drill bit, etc. The drill provides power to drive the drill pipe and drill bit to drill and obtain deep core samples. According to different depths and strata, corresponding to different types of drilling rigs

Core tube - coring tool

1. Single layer core pipe

The single pipe drilling tool has simple structure and convenient processing. It is a common coring tool for hard alloy and steel particle drilling. The flushing liquid in the single pipe drilling tool is sent into the core pipe by the drill pipe. The drill accessories that directly rush to the top of the core, and the impact and friction of the core caused by the rotation of the core pipe, are very easy to wear and tear the core, so they are only applicable to relatively complete and stable formations.

2. Double core tube

The double-layer core pipe is formed by adding a core containing pipe (inner pipe) to the original core pipe (outer pipe). According to whether the inner pipe rotates during drilling, it can be divided into two types: double acting and single acting:

Double layer double acting core tube (double acting double tube) - the outer tube rotates and the inner tube also rotates.

Double layer single acting core tube (single acting double tube) - the outer tube rotates but the inner tube does not rotate.

The double-layer core pipe can isolate the scouring effect of the washing liquid on the core. Double acting double pipe water isolation without vibration isolation, used for soft, loose and easily eroded formations;
