GK 200 Crawler Mounted Borehole Drill Rig Advantages
1. It has a hydraulic automatic feeding mechanism to improve drilling efficiency and reduce labor intensity.
2. It adopts the ball card clamping mechanism instead of the chuck, and can implement the non-stop bar, easy to operate, safe and reliable.
3.The hoist is equipped with a frame to form a double-sided support star structure that can withstand strong impact.
4.Four sets of bearing positioning of the vertical axle box ensure that the gyrator has sufficient rigidity to deal with complex geological conditions such as gravel layer and pebble layer.
5.This machine adopts a taper clutch, which has the characteristics of large transmission torque, convenient operation and maintenance-free.

1.2 Geological core drilling, physical prospecting.
1.3 Small grout Confucius, drill hole drilling.
1.4 Small well drilling.
What is the reason for the high oil temperature in the drill?
The high temperature in the drilling rig is generally divided into the high temperature of the gearbox, the high temperature of the hydraulic oil, and some are the high temperature of the engine cooling liquid. In fact, the reason for the high temperature of the gearbox is very simple. The main reason is that the size and shape of the bearing or gear and housing are not standard or the oil is unqualified. Now let's give you a detailed analysis.
Hydraulic oil temperature is too high:
First of all, the temperature of hydraulic oil is too high. According to hydraulic theory and maintenance experience in recent years, the main reason for the high temperature of hydraulic oil is too fast heat generation and too slow heat dissipation. The oil inlet pipeline and hydraulic oil tank of the hydraulic pump are not sealed tightly, the oil inlet filter element is blocked, the hydraulic system pipeline is not unblocked, and the internal leakage of the hydraulic pump will cause a large amount of heat to be generated in the hydraulic oil, so that the temperature of the hydraulic oil will rise rapidly due to excessive heat generation.
The internal channel of the hydraulic oil radiator is blocked, the external dust of the radiator is too large, the wind force is not enough, and the hydraulic oil does not pass through the hydraulic oil radiator, which can lead to the high temperature of the hydraulic oil due to the slow heat dissipation
