Under What Circumstances Will Fuel Consumption Increase During The Operation of A Rotary Drilling Rig

If the fuel consumption of a rotary drilling rig suddenly increases during operation, it is necessary to be vigilant. This may be a signal of equipment abnormality or improper operation. The following are six common situations that lead to increased fuel consumption and their cause analyses:

1.Engine malfunctions: Poor atomization of fuel injectors, abnormal valve clearance or severe carbon deposits in the cylinder can lead to incomplete fuel combustion, resulting in a significant increase in fuel consumption. Timely inspection and maintenance are required.

2. Hydraulic system leakage: Aging and damage of hydraulic pipelines and seals cause oil leakage. The system consumes more energy to maintain pressure, which indirectly leads to increased fuel consumption. Regular inspection of leakage points is necessary.

3. Improper selection of drill bits: Using soft soil drill bits with worn tooth tips in hard rock layers or forcing drilling with overly large bucket capacity will increase drilling resistance, forcing the engine to operate at high load and resulting in higher fuel consumption.

4. Poor operating habits: Frequent sudden acceleration, prolonged idling, or blindly pursuing speed and slamming on the accelerator during drilling can all lead to fuel waste. It is necessary to standardize the operating methods.

5. Harsh construction environment: When working on muddy and soft ground, the equipment has high resistance during movement and requires continuous high-power output. In high-temperature weather, the increased load on air conditioners will all lead to higher fuel consumption.

6. Fuel quality issues: Using fuel with high impurity content or incorrect grade will lead to a decrease in engine combustion efficiency. Not only will fuel consumption increase, but it may also damage the components of the fuel system.

Conclusion: The increase in fuel consumption of rotary drilling RIGS is usually closely related to the equipment status, operation mode and construction conditions. Regular maintenance and upkeep of equipment, selection of appropriate drill bits, standardized operation habits, and the use of qualified fuel can effectively control fuel consumption. If the fuel consumption is abnormal and the investigation fails, it is necessary to contact professional technicians for maintenance in a timely manner to avoid losing more than you gain.
