At present, the most difficult problem is that the low temperature performance is not qualified, which is mainly manifested in the immature exhaust process. Many improvements have been made to the vacuum extraction process, but the effect is not ideal, and experts are urgently needed to guide. The emulsion drill studied in this topic has the following requirements: 1, filter components (valve core, valve stem, valve plate, meshing gear, etc.) using QPC surface treatment technology, improve the product corrosion resistance, wear resistance, prolong the service life of the product; 2. Set the inlet position of 15-25 casting manufacturers in the horizontal direction to accelerate the inlet speed, increase the inlet volume of gear meshing space, improve the volumetric efficiency of the rotary motor, and greatly improve the output power of the emulsion drilling machine; 3. The control valve of the emulsion drilling rig adopts the combined structure of pressure control and flow control, and the same inlet and outlet are designed. Easy to adjust, reduce pressure and flow pulsation, improve the efficiency of hydraulic transmission, and reduce the weight of the emulsion. The hydraulic mining drill car developed by our company is mainly used for mining operation under the mine, which requires the realization of hydraulic positioning and pushing operation at any Angle. Now the index design has been done, and relevant professionals are needed to complete it together. One of the company's R & D project principles is innovation. The enterprise mainly carries out original innovation large-scale casting production plant for electromechanical products with potential market prospects, and carries out digestion, absorption, promotion and re-innovation strategy for products already existing in the market. Enterprises regard innovative talents as the most precious wealth of enterprises. The company has a high-quality R & D team, pay more attention to the gathering of the whole society's innovative people, for rapid success, high quality success and form alliances, for China to create the trend and do their own responsibility.
