Vacuum pump system for vacuum transportation characteristics :
(1) the structure of the equipment is simple, manufacturing, processing, device is comparable to the convenience, control cost is less, the establishment time is short. The main component of vacuum conveying system is the welding structure of section steel plate, which is composed of the components of pipe and tank shape. The relative movement and maintenance operation of each component are relatively easy. If some control equipment is added, it is easy to complete automatic operation.
(2) recommended high efficiency, no return transport equipment. Other means of transport all have the defect that the transport wrist is free to return, and the transport medium of vacuum recommendation is air, only need to be discharged into the atmosphere at the terminal, in the recommendation process, the inlet can be continuously fed to complete continuous recommendation.
(3) good labor health conditions, vacuum recommended when the material in the pipe operation, pipe in the negative pressure, dust will not be released flying, material will not fly and damage the environment. In the process of recommendation, can also stop sorting, boring and other intermediate treatment. If the material is recommended under negative pressure, because water is easy to evaporate under negative pressure, so, even if other dry wrist is not used, the material with higher moisture in the process of recommended, will also get a certain dry role, the application of material particle weight is different, the design of the appropriate discharge port to the material sorting.
(4) in addition, vacuum recommended pipeline, easy to tailor to set up the pipe network, layout cumbersome sensitive, can fully apply the field air product, easy to comply with the operating environment.
Vacuum conveying application :
Vacuum transport, absorption and lifting equipment, are the application of vacuum and atmospheric pressure difference between the force generated by the force to do work. Since this mechanical energy has the property of uniform pressure everywhere, it can be applied absolutely and closely to the plane of any shape. At present, these vacuum equipment are mostly used in sucking fish, grain, flour, pulverized coal, tobacco, cement, mud, pulp, powder mineral powder chemical products, cement floor, prefabricated board, airport and highway cement run fast drying, workshop lifting, machine tool fixtures, glass shipping, sucking milk, dust. Abortion absorption fetus: sputum aspiration, pleural effusion suction, pus, intestinal absorption and absorption of atomic bomb explosion produced by the radiation dust and other consumer operations. These equipment have the characteristics of simple structure, easy operation and maintenance, transportation, no vibration in the process of lifting and absorption, high consumption efficiency, safe and reliable transportation of easily damaged objects, no pollution to the environment and so on. Therefore, it has a wide range of applications and prospects.
Vacuum appearance is also an important aspect of the application of differential pressure force, in recent years in the military map, number of books for the blind, and shown to touch type, advanced ceramics, concrete, refrigerator, washing machine parts, toys, copy panel is embossed and cultural relics, the traveling wave tube and backward wave tube in the pillar fine spinning forming, analyze the chamber in the mass spectrometer and waveguide manufacturing of microwave system, is widely adopted this technology.
Another category of application of vacuum mechanics is vacuum filtration and vacuum impregnation. At present, chemical industry, sugar, cement and other industrial departments have begun to use a large number of continuous vacuum filtration, it is easy to apply the viscosity of suspension pressure differential force action, through a fine sieve hole and the suspension of liquid and solid separation. Vacuum filtration can save a lot of cotton cloth in dye industry. Vacuum impregnation is a new technology that stops vacuuming and then impregnation and filling some new materials in the liquid. This process has been used in oil bearing, fishing net fiber, leather, non-electrolytic capacitor, transformer, motor stator coil and other products has significantly improved the production quality. In addition this kind of craft stops to get together fat resin to dip to loose and inferior lumber, stop to pencil wood wax kind dip makes its alter original natural property to change inferior the purpose that is high grade, had reached the effect that gives period.
