1. Description of GH sand and gravel pump
Naipu G series Gravel and sand slurry pump is
designed specifically for continuous pumping of extremely aggressive
slurries, with a wide particle size distribution. Capable of handling
large particles at consistently high efficiencies results in low cost of
ownership. The large volume internal profile of the casing reduces
associated velocities further increasing component life.

The expert group believes that this project has completed the requirements of various task indicators such as the development of two series of products identified by the task book, the declaration of two patents and the formulation of enterprise standards. Developed a new high-performance bonding agent, the choice of super-hard abrasives, grinding wheel manufacturing process and testing technology, grinding test, etc., and developed CBN grinding wheel and resin/metal composite for crankshaft, camshaft high speed, ultra-high speed grinding ceramic bond. The bonding agent diamond grinding wheel has realized the engineering application; it has broken through a number of key technologies in high-strength ceramic bonding agent and resin/metal composite technology, and has achieved a number of innovative achievements.
In the appraisal of the scientific and technological achievements of the “Development and Development of Superhard Material Grinding Wheelsâ€, the appraisal committee believes that this topic has made breakthroughs in the key technologies of ultra-high-speed ceramic CBN grinding wheel manufacturing. The self-developed high-strength ceramic bond and its preparation technology ensure that the subject product meets the requirements of ultra-high-speed grinding processing with a speed of up to 160 m/s; the complex profile grinding wheel working layer structure and forming technology are developed to solve the complex surface The uniform forming problem of the grinding wheel realizes uniform wear of different parts of the grinding wheel for precision forming grinding. This project has made breakthroughs in the key technologies of resin and metal compounding. It has successfully developed a resin/metal composite binder for the first time in China, effectively improving the wear resistance of the grinding wheel around the blade; and through working the surrounding diamond grinding wheel. The optimized design of the structure solves the technical problem that the grinding wheel for hard and brittle material such as ceramics cannot achieve high efficiency, high surface quality and high durability integration. The products have replaced imported similar products, and their technical achievements have reached the domestic leading level.
High-speed ceramic CBN grinding wheel and composite bond diamond grinding wheel are new type of super-hard material grinding tools, which are one of the essential and irreplaceable basic equipments for modern industrial advanced manufacturing technology. The successful development of this product not only solves the key technology of high-speed ceramic CBN grinding wheel and high-hardness blade CNC peripheral grinding wheel, but also develops high-performance ceramic bonding agent suitable for high-speed grinding and resin metal composite bonding agent with excellent comprehensive performance. And its preparation technology, to promote China's high-speed, high-efficiency, precision abrasive manufacturing technology breakthrough, enriching the type of bonding agent in China's abrasives industry. Camshaft, crankshaft processing high-speed ceramic bond CBN grinding wheel and composite bond blade peripheral grinding wheel three types of subject products, breaking the foreign monopoly on this field in China, played a leading industry technology development, promote industry technology progress, guide industry regulation Product structure and demonstration role of improving competitiveness, thereby enhancing the industry's ability to participate in international market competition. It provides strong support for the development of the industrial sector with priority support and priority development in China's equipment manufacturing, automobile industry and tool manufacturing industry, which is conducive to enhancing the supporting role of the equipment manufacturing industry for the development of the national economy and the guarantee role of national security.
