ST260 Crawler Mounted Drilling Rig Features

 

1. The chassis of the drilling rig adopts a professional traveling motor with a gearbox, which has a longer service life.

2. The gearbox is integrally formed, double motors, stronger power, larger torque, more durable, and low maintenance cost;
3. It adopts professional excavator chassis, which is sturdy and durable, bears heavy load, wide chain plate, and has little damage to hard road surface;
4. Each hydraulic oil pipe is covered with a thick protective sleeve, which makes the oil pipe have a longer service life;
5. Dual systems can be installed: 1. Air power system with air compressor 2. Mud pump system with mud pump

 

Drilling method of pebble layer

 

1 conventional drilling methods and characteristics

At present, conventional drilling methods such as diamond drilling, clean water flushing, pipe reaming and mud circulation are generally used, while rotary drilling, dry drilling, pipe following, percussion, steel wire drill and other coring methods are used for core mining.

The disadvantages of these methods in drilling pebble layer are large drilling load, many accidents in the hole, low drilling efficiency and poor coring quality.

2. Drilling method and characteristics of diamond drilling tool combined with vegetable glue washing fluid

In order to meet the requirements of drilling in various hard and fragile formations, a series of single acting double barrel diamond drilling tools combined with vegetable gum washing fluid have been specially developed. It is also a relatively advanced method of drilling progressive cores in such formations at present. This method is a drilling process using vegetable gum as washing fluid and diamond as drilling tool.

The main characteristics of this process are small rotary resistance, high drilling efficiency, good coring quality, and strong ability to discharge sand and carry rock powder.

 

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
