Vacuum pump system in vacuum transportation
Vacuum pump is a kind of rotary variable volume vacuum pump, which can be used only with the cooperation of the front pump. It has a large pumping speed in a wide pressure range and is insensitive to the dust and water vapor contained in the extracted gas. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries. It includes water ring vacuum pump, reciprocating vacuum pump, slide valve vacuum pump, rotary vane vacuum pump, roots vacuum pump and diffusion pump, etc. at present, these vacuum pumps are the essential main pumps in the application of vacuum pump technology in various industries of national economy.
Vacuum transport, absorption and lifting equipment all use the force generated by the pressure difference between vacuum and atmosphere to do work. Due to the fact that the pressure of this kind of mechanical energy is average everywhere, it can be applied to the plane of any shape.
At present, most of these vacuum equipment are used for sucking fish, grain, flour, coal powder, tobacco, cement, mud, pulp, powdered mineral powder chemical products, cement floor, prefabricated board, airport and highway cement road quick drying, workshop lifting, machine tool fixture, glass shipping, sucking milk and dust. Absorption of fetus by artificial abortion: suction of sputum, pleural effusion, pus, aspiration of intestine and absorption of radiation dust produced by atomic bomb explosion. These equipments are simple in structure, easy to operate, maintain, transport, no vibration in the process of lifting and absorption, high in consumption efficiency, safe and reliable in transporting easily damaged objects, and no pollution to the environment. Therefore, it has a wide range of applications and prospects.
Vacuum profile is also an important aspect of the application of differential pressure. In recent years, it has been widely used in plane military map, blind books, digital model, advanced ceramics, concrete prefabrication parts, refrigerator washing machine plates, toys, replica reliefs and cultural relics, fine-grained pillar forming in TWT and BWT, analysis room in mass spectrometer and waveguide manufacturing in microwave system This technology.
