704 successfully developed high-pressure internal gear pump

Recently, the high-pressure internal gear pump test developed by China Shipbuilding Industry Corporation's 7th Fourth Research Institute was successful. The test results show that the pressure and flow performance indexes of the four product prototypes have reached the technical level of similar foreign products.
High-pressure internal gear pumps are widely used in injection molding machines, bending and shearing machines, forging and die-casting industries. It is estimated that the annual demand for this product is about 1 million units, and the annual market capacity is about 3 billion yuan. In 2011, the company started the research and development of the product, and completed the prototype manufacturing and testing in October 2013. At present, the seven-fourth has formed a small-volume production capacity of 500 high-pressure internal gear pumps.

Synthetic Cryolite

Synthetic cryolite is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.95-3.01g/cm3, melting point about 1000°C, specific heat 1.056j/g°C at 18-100°C. It`s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800°C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Uses:

It`s mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for Resin and rubber-boned Abrasive wheels.
