The mining operation environment is harsh and highly dangerous, and the pressure calibration pump has an extremely important role in ensuring the safe and efficient operation of mining equipment. In the ventilation system of a mine, the wind pressure of the fan needs to be precisely controlled and calibrated. The pressure calibration pump can calibrate the pressure monitoring and control system of the ventilation equipment, ensuring good ventilation underground, timely exhausting harmful gases, creating a safe working environment for miners, and ensuring the stable operation of the ventilation system under different working conditions and reducing energy consumption. In the drainage system of a mine, the drainage pressure of the water pump is crucial. The pressure calibration pump can calibrate the pressure device of the drainage pump, enabling the water pump to efficiently drain the accumulated water underground, preventing water disasters and ensuring the continuity of mining operations. In the hydraulic mining equipment of a mine, such as hydraulic rock drills and hydraulic loaders, the pressure calibration pump can calibrate the hydraulic system pressure of the equipment, ensuring the normal operation of the equipment under powerful and stable hydraulic power, improving mining efficiency, reducing equipment failure and maintenance costs, and promoting the safe production and sustainable development of the mining industry.
