Development Of Pneumatic Dual Fluid Injection Pump Applied In Mines Industry

The method of using chemical grouting soft coal mine broken rock reinforcement, and permeable rock to water grouting, grouting methods to prevent combustion of spontaneous combustion of coal mine production to increase efficiency and safety of an effective method.This article discusses and describes several widely used in coal mine, tunnel and other underground works quickly and efficiently processing and controlling new chemical grouting surrounding rock consolidation, cavity filling and plugging materials and supporting application technology, and traditional Chemical grouting technology and materials, the performance characteristics of the materials and process technology is more scientific, standardized and stability, solving the key problems of underground works in targeted and obvious effect.However, the existence of chemical grouting technology behind the construction process, not grouting equipment, supporting technology problems, lagging behind the progress of grouting technology in the practice of grouting technology in chemical grouting technology has become the key to development. Grouting equipment selection applies or not, is directly related to the cost effectiveness and quality of grouting, grouting equipment, key equipment is composed of injection pump with the continuous development of grouting materials technology, grouting equipment for the more important.This article discusses in detail the technology is designed to promote the coal liquid with a series of air injection pump double research and development process, including the injection pump of the overall design scheme, and the cylinder design calculation, design and calculation of grouting cylinder, standard the choice of pieces, rendering non-standard pieces of drawings, grouting cylinder seat finite element analysis, matching accessories mixers, the design of sealing tubes. And through industrial experimental results and analysis of the design to verify the contents. The pump is also introduced in the domestic large-scale coal mine tunnel in the typical engineering project application.Currently, with the new aerodynamic package grouting technology dual fluid injection pump is only just beginning in China, developed the equipment for China in the coal industry by greatly improving production efficiency and safety of mine to provide a safety equipment. To promote the new chemical grouting material and grouting process provides equipment protection.New chemical grouting materials and supporting application of technology to achieve high quality of the performance of grouting materials, application of technical scientific, normative and accuracy of application and strong. That the application materials and supporting equipment to carry out combined research and extension is still a long term, actively introduce and promote advanced technology is the foundation to adapt to the rapid development of China's industry needs.
