Application of vacuum pump unit

News


The water ring vacuum pump unit is mainly composed of roots pump and water ring pump as the front pump in series. The water ring pump selected by the vacuum pump unit is more advantageous than other vacuum pumps, because the vacuum pump unit not only overcomes the shortcomings of the pressure difference of the limit pressure of a single water ring pump (the limit pressure of the unit is greatly improved compared with the limit pressure of the water ring pump) and the low pumping rate under a certain pressure, but also retains the advantages of the Roots pump that can work quickly and have a relatively large pumping rate. It can be adapted to pump a large amount of condensable steam, especially when the gas ballast oil seal mechanical vacuum pump has insufficient ability to remove condensable steam, or the solvent used

It can be adapted to pump out a large amount of condensable steam, especially when the gas ballast oil seal mechanical vacuum pump has insufficient ability to remove condensable steam, or the solvent used can deteriorate the pump oil and affect the performance, or the vacuum system does not allow oil pollution. If equipped with explosion-proof motor and electrical appliances and comply with the corresponding safety rules, but also able to pump out flammable and explosive gases.

Vacuum pump unitApplication

1, Pharmaceuticals and Chemicals

Vacuum pump applications include medicine, pesticides, cosmetics and wash hygiene products, soaps and synthetic detergents, surfactants, printing inks and their additives, adhesives, photosensitive materials, water treatment agents and polymer flocculants, paper additives, leather additives, mineral flotation agents, foundry chemicals, metal surface treatment agents.

Applicable products:Vacuum pump unitWater ring vacuum pump series, slide valve vacuum pump series, reciprocating vacuum pump series.

2. Vacuum coating, vacuum drying, surface treatment

The film layer prepared in vacuum includes plating crystalline metal, semiconductor, insulator and other simple substance or compound film. Although chemical vapor deposition also uses vacuum means such as reduced pressure, low pressure or plasma, in general, vacuum coating refers to the deposition of thin films by physical methods. Vacuum pump applications play a vital role in the coating industry, surface treatment and drying.

3. Vacuum smelting, brick and ceramic manufacturing

The use of vacuum pumps is reflected in vacuum technology. This is a very critical part of the metallurgy and brick ceramic industry. It can be used to prevent the metal from being oxidized due to high temperature during processing. The moisture and air inside the bricks and ceramics are removed by vacuum to ensure high quality.

4, food packaging, milking, beverage industry

Vacuum packaging technology originated in the 1940 s. In 1950, polyester and polyethylene plastic films were successfully used for vacuum packaging, and vacuum packaging has developed rapidly since then. Vacuum packaging is to extract all the air in the packaging container and seal it, maintain the bag in a highly reduced pressure state, and the thin air is equivalent to the low oxygen effect, so that microorganisms have no living conditions to achieve the purpose of fresh fruit and no disease and rot.
