1. selection of drilling tools and processes should be reasonable
Choosing appropriate drilling tools according to the construction geological conditions can not only save fuel but also protect the drill pipe. When drilling is difficult, the drilling speed can be improved by changing the drilling mode through different drilling combinations. In the process of large-diameter pile formation, small-diameter drilling tools are first used for drilling and then large-diameter drilling tools are used for reaming, which can effectively reduce resistance and improve drilling efficiency.
The drilling of hard stratum shall be of jog pressure type, the drilling of loose soil stratum shall be of long stroke pressure type, and the pressure raising and pressurizing method shall be selected when drilling floating stone. According to different geology and hardness, the reasonable pressure method shall be selected, which can also improve the construction efficiency of drilling rig and effectively reduce oil consumption.
After the drilling tool is filled, the power head shall be properly rotated during lifting, which can reduce the lifting resistance and fuel consumption.
The idle speed function of the 2. should be integrated, and the selection of drilling tools and processes should be reasonable.

3. use idle function to be reasonable
Avoid crawler drilling rig long idle, in the short-term shutdown when the use of automatic idle, these small details can achieve the purpose of saving fuel.
4. control the throttle position
A working cycle of the crawler drilling rig includes: lowering the drill pipe → drilling with the power head → reverse rotation of the power head → lifting the drill pipe → turning on the vehicle → throwing the soil → turning on the vehicle to reset; Under the same operating conditions, the low-speed engine is used. Low fuel consumption and high fuel efficiency.
It is suggested that the operator of the drilling rig should reasonably select the gear according to the comprehensive analysis of geological conditions, construction period and daily workload. The higher the engine speed of the drilling rig, the faster the walking speed and the more fuel consumption. It can be seen that the fuel efficiency of low-speed walking is higher than that of high-speed walking.
