[Asia Fluid Network News] Dry-type screw vacuum pump, which uses a pair of screws in the pump housing for synchronous high-speed reverse rotation of the suction and exhaust air suction device. Its advantages make up for the lack of oil-sealed vacuum pump, we all call it an upgraded version of the oil-sealed vacuum pump. However, the cost of dry screw vacuum pump is also its inadequacies. Next, it mainly introduces the advantages and disadvantages: Dry-type screw vacuum pump Dry-type screw vacuum pump Advantages: 1, the working chamber and screw rotor surface anti-corrosion coating, can adapt to harsh conditions 2, the gas in the pump without compression, suitable for extraction Condensable gas 3, no fuel, no drip 4, simple structure, easy maintenance. 5, was pumping gas directly discharged from the pump body, do not pollute the water, no environmental pressure, gas recovery more convenient. Dry-type screw vacuum pump Disadvantages: 1, due to the difficulty of screw pump processing, screw pumps used in China mainly rely on imports, the price is very expensive. 2, not suitable for extracting explosive gas. 3, not suitable for pumping high oxygen gas. With the development of the industry in our country, the requirements for a clean vacuum environment are getting higher and higher in the manufacturing of semiconductors, liquid crystal displays and the like, and the traditional oil-vacuum pumps have not met such demands. Screw-type dry-type vacuum pump with its pumping speed range, simple and compact structure, suction chamber components without friction, long life, low energy consumption, oil-free pollution, more and more manufacturing and application units attention, dry Vacuum pump market occupies an important position. In developed countries such as Europe, America and Japan, screw-type dry-type vacuum pumps have replaced more traditional oil pumps in many fields.

Boron nitride ceramics have good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and are ideal heat dissipation materials and high temperature insulation materials. Boron nitride has good chemical stability and is resistant to most of the molten metal. It also has good self-lubricating properties. Boron nitride products have low hardness and can be machined with an accuracy of 1/100 mm. Boron nitride can be used in the manufacture of high-temperature containers for metallurgical melting, semiconductor heat-dissipating insulation parts, high-temperature bearings, thermowells, and glass forming dies.
