During the construction process of rotary drilling rigs, we encounter different geological structures, and the drilling rigs and operating methods used are also different. The amount of fuel consumed by the rotary drilling rig during construction is related to these factors. If we can master certain skills in daily construction and maintenance, we can not only save fuel and improve economic efficiency, but also reduce environmental pollution and play an environmental protection role. Below, the technical engineers of Shandong Liqiang Machinery Company will share some methods and techniques for saving fuel in the construction and maintenance of rotary drilling rigs.#drive rigs#
1. Fuel-saving operating methods
(1) The idling function must be used correctly. During the operation of the rotary drilling rig, in order to avoid fuel waste and damage to the engine, long-term idling should be avoided. When the rotary drilling rig is stopped for a short time, the automatic idling function can be used to save fuel.
(2) The selection of drilling tools and construction methods should be reasonable. According to the geology and the current condition of the rotary drilling rig, the drilling tools should be selected reasonably. This can not only reduce the load and increase the drilling speed, but also save fuel and play a certain protective role for components such as the drill rod. Using high-quality carbide cutting bits or roller cone bits for drilling into rock can not only reduce drill bit wear and replacement frequency, but also improve drilling speed and fuel efficiency. Selecting the appropriate drill rod model can effectively reduce fuel consumption during drill bit lifting and lowering.
(3) Properly control the throttle gear. Many operators, when performing rotary drilling, always set the throttle to the highest gear regardless of the operation. This is actually an incorrect operating method, wasting fuel and damaging the equipment. Extensive testing has shown that under the same rotary drilling conditions, using a lower throttle gear results in lower engine fuel consumption and higher fuel efficiency. In daily construction, operators should comprehensively consider geological conditions, workload, and project schedule to rationally select the appropriate gear.
2. Fuel-saving maintenance methods.#drive rigs#
(1) Keep the air filter clean. If the air filter is too dirty, it will cause high airflow resistance, incomplete combustion of the air-fuel mixture, and a decrease in engine power. Tests show that when the air filter is partially blocked, fuel consumption increases by 5%. Drivers should maintain the air filter as follows: Check and clean the air filter element every 100 hours, and replace it every 500 hours. During maintenance, do not clean the filter element by impact or vibration; use compressed air, pressurized water, or detergent instead. Ensure the cleaned filter element is completely dry before installing it into the filter housing.
(2) Regular Fuel System Maintenance
If the fuel filtration is ineffective, impurities in the diesel fuel can enter the fuel injection pump, accelerating the wear of precision components, leading to decreased engine power and increased fuel consumption. If moisture or gum in the fuel enters the cylinder, it will cause poor combustion of the combustible mixture, resulting in decreased engine power and increased fuel consumption. Therefore, it is essential to regularly replace the coarse and fine fuel filters and frequently check the fuel pump and injectors for internal leaks or damage. If the fuel pump or injectors leak or are damaged, they should be repaired promptly.
In addition, high-quality fuel should be used. Using inferior fuel will not only prevent the engine from reaching its rated power and increase fuel consumption beyond the specified limits, but will also lead to premature damage to fuel system components and shorten overhaul intervals.
(3) Regular Oil Changes: Failure to change engine oil at the prescribed time or using inappropriate oil will exacerbate wear on engine components, adversely affecting engine performance and lifespan, and increasing fuel consumption. Therefore, the same series, grade, and viscosity of engine oil should be selected strictly according to the instruction manual, and the oil should be changed regularly as specified in the manual.
(4) Other Maintenance: Properly adjusting track tension and promptly cleaning mud adhering to the walking device can reduce walking resistance and lower fuel consumption. In addition, keeping the hydraulic oil radiator and water radiator clean and maintaining the hydraulic oil and coolant temperatures within a reasonable range will help improve operating efficiency and reduce fuel consumption.
The operating conditions of rotary drilling rigs are relatively complex, and the load changes frequently and within a wide range during construction, resulting in relatively high fuel consumption. By rationally controlling fuel consumption and improving efficiency while completing the same workload, we can reduce our construction costs and greatly improve our economic benefits!#drive rigs#
