Engine is the main power source of a rotary drilling rig in various industries such as oil and gas exploration, geothermal drilling, and mineral exploration. These engines are usually large and powerful because they must generate enough torque and horsepower to drive the rig’s rotary table and rotary drilling equipment. The engines used in rotary drilling rigs are usually diesel engines, known for their durability, high efficiency and high power. The power generated by the engine is transmitted to the turntable of the drilling rig through a complex transmission system, turning the drill bit to drill into the ground. These engines are designed to withstand harsh operating conditions such as extreme temperatures, high altitudes and dusty environments. They also require regular maintenance to ensure peak performance and prolong their life. Rotary drilling rig engines play a vital role in the drilling process as they provide the necessary power to penetrate formations and extract valuable resources. Without reliable and efficient engines, the drilling process would be slow, inefficient and costly.
The engine of the rotary drilling rig is very important, but the hydraulic motor of the rotary drilling rig, as one of the actuators of the hydraulic system, is a hydraulic device that drives the rotation of equipment components, and is also an important part of the rotary drilling rig.
What are the requirements for hydraulic motor selection?
(1) Hydraulic motors have higher efficiency in medium and high pressure areas. When configuring the working pressure of the motor, taking into account its working life and power utilization rate, the motor of the rotary drilling rig should be operated near the medium pressure as much as possible.
(2) The hydraulic motor has higher working efficiency at medium speed.
(3) Reduce the motor displacement, and its efficiency will decrease, especially at low displacement and low speed, the efficiency is lower, and the working capacity is very weak. The motor can only guarantee high-speed operation when it has a large displacement.
In the actual design process, the motor and the pump have a matching relationship in terms of displacement. Generally, the displacement of the motor should be 1.2 to 1.6 times the displacement of the pump. Otherwise, the system pressure will be too high, the speed fluctuation will be too large, The motor speed is too high, the engine stalls and the work efficiency is low. Generally speaking, larger motor displacement is better, but larger motor displacement will make the manufacturing cost prohibitive.
