Design and Calculation of Hydraulic Pump Station for Narrow Crawler Directional Drilling Rig

Taking the hydraulic pump station of a narrow crawler directional drilling rig as the research object, the design and calculation method of the motor pump set, the type selection and assembly requirements of the coupling were expounded. According to the characteristics of the compact structure of the drilling rig, combined with the structure layout of the whole machine,hydraulic pump parameters and the temperature rise of the drilling rig,the volume of the oil tank and the cooler were calculated and carried out the type selection. The measures to ensure the cleanliness of oil were explained, and the installation positions and selection methods of various oil filters in the hydraulic circuit of drilling rig were put forward,which provides a strong guarantee for the stability of the hydraulic system of the drilling rig. Through the rig test-bed and field test, it shows that the designed hydraulic pump station can meet the requirements of normal operation and high reliability of the rig. Provide a reference for the design of hydraulic pump station of directional drilling rig.
