1. Introduction
The series of mining crawler-type large-flow mud pump trucks is one of the core equipment of the complete set of equipment for underground directional drilling construction in coal mines. The pump truck integrates liquid-driven mud pump components, electromagnetic starters, control consoles, and other devices. It is used to provide high-pressure water to drive the bottom motor of the hole to achieve directional drilling when the power head drilling rig is drilling. It has the features of autonomous walking, good integration, advanced performance, easy operation, and safe operation, which can effectively improve the efficiency of gas drilling construction. It is mainly used in rotary steering and steering large-diameter coal seam drilling construction, or large-diameter directional drilling construction of complex rock formations on the roof. The core equipment for the application of "holes instead of tunnels" technology provides equipment guarantee and technical support for safe and efficient production of coal mines.
2. Technical Characteristics
1. The pump truck adopts an integral crawler structure, which is composed of a pump station, a crawler body, a control panel, a mud pump assembly, a locomotive light assembly, an electromagnetic starter, and other parts. Each part is connected with high-pressure hoses and fixed to the car body platform through bolts. It has a compact structure and high reliability. Significantly reduces auxiliary time, improves drilling efficiency, is flexible, and has strong applicability.
2. All types of hydraulic components of the pump truck adopt the Rexroth brand, including hydraulic pumps, hydraulic motors, multi-way valves, pilot control handles, manual reversing valves, and other hydraulic accessories, which ensure the reliability, controllability, and transmission efficiency of the drilling rig. significantly improved.
3. BLY800/12 pump truck adopts an open hydraulic control system with constant power control technology, which has the characteristics of high transmission efficiency, and simple and reliable control; the mud pump assembly adopts a three-cylinder reciprocating piston structure, which is driven by high-torque radial hydraulic pressure. Motor-driven, with the characteristics of high pressure, step-less speed regulation, reasonable parameters, advanced structure, and reliable performance.
4. BLY1000/16 pump truck adopts a closed hydraulic control system with load-sensitive and constant power control technology, which is suitable for larger flow output control characteristics. It has high transmission efficiency, simple and reliable control, a small system of ineffective heat loss, and significant energy saving. Advantages: The mud pump assembly adopts a five-cylinder reciprocating piston structure and is driven by a high-torque radial hydraulic motor. It has the characteristics of high pressure, step-less speed regulation, reasonable parameters, advanced structure, and reliable performance.
5. The pump truck is equipped with an electromagnetic starter with multi-parameter power output to facilitate multi-functional needs.
