The use of mechanical, physical, chemical, physical and chemical methods to pump gas, in order to obtain and maintain the vacuum device. Vacuum pumps and other equipment (such as vacuum vessel, vacuum valve, vacuum measuring instrument, connecting pipe, etc.), which is widely used in electronics, metallurgy, chemical industry, food, machinery, medicine, aerospace and other departments.
According to its working principle, basically divided into two types of gas delivery pump and gas trapping pump.
Gas pump: 1, liquid ring vacuum pump (water ring vacuum pump) 2, reciprocating vacuum pump 3, rotary vane vacuum pump 4, stator type vacuum pump 5, slide valve vacuum pump 6, trochoidal vacuum pump, dry vacuum pump 8, roots vacuum pump 9, molecular vacuum pump 10, traction molecular pump 11, compound vacuum pump 12 water injection vacuum pump 13, the gas jet pump 14, steam jet pump 15, diffusion pump
Gas capture pumps include: adsorption pump and low temperature pump, etc..
At present, the most widely used in industry is the water ring vacuum pump and rotary vane vacuum pump.
W type reciprocating vacuum pump
(ModelWPistonVacuumPump) is one of the main vacuum equipment to obtain a rough vacuum. Widely used in chemical, food, building materials and other departments, especially in the vacuum crystallization, drying, filtration, evaporation and other process is more suitable for.
2X type rotary vane vacuum pump (Model2XSlidingVaneRotaryVacuumPump)
One of the basic equipment used to pump the gas in a closed vessel. It can be used alone, also can be used as a booster pump, diffusion pump, molecular pump use of the first stage pump. This type pump is widely used in vacuum melting, vacuum coating, vacuum coating, vacuum drying, vacuum coating, vacuum coating, vacuum drying, etc..
2XZ type rotary vane vacuum pump (Model2XZSlidingVaneRotaryVacuumPump)
Has the advantages of compact structure, small size, light weight, low noise, small vibration and so on. Therefore, it is suitable for the use of the first - stage pump, and it is more suitable for precision instruments and laboratory use. For example: mass spectrometry instrument, refrigerator assembly line, vacuum freeze dryer, etc..
XD type rotary vane vacuum pump
(ModelXDSlidingVaneRotaryVacuumPump) can be used at any entry pressure, has been widely used in food packaging, vacuum packaging, plastic industry vacuum forming. Printing industry paper transport, vacuum fixture, and vacuum suction, etc..
SZ, SK series water ring vacuum pump
(ModelSZWaterRingVacuumPump) is mainly used for rough vacuum. In the process of extracting gas. It is mainly used for pumping air and other non corrosive, insoluble in water, containing a small amount of solid particles of gas, in order to form a vacuum in a closed vessel. A small amount of liquid is allowed in the gas mixture. It is widely used in machinery, pharmaceutical, food, petrochemical and other industries.
2SK, 2SK-P1 series two stage water ring vacuum pump
(Model2SK, 2SK-P1WaterRingVacuumPump) is mainly used to remove air and other corrosive, insoluble in water, allowing the gas containing a small amount of solid particles. Widely used in food, textile, pharmaceutical, chemical and other industries of vacuum evaporation, concentration, impregnation, drying and other process. This type of pump has the characteristics of high vacuum degree, simple structure, convenient operation, reliable operation and convenient maintenance.
JZJS type roots -- water ring pump unit (ModelJZJSRoots-WaterRingVacuumPumpSystem)
This unit is specially suitable for the process of pumping water with a large amount of water vapor and certain corrosive and can be found in the process of a certain amount of water vapor and a certain corrosive gas. Such as: vacuum distillation, evaporation, dehydration, crystallization, drying and other process.
JZJX type roots rotary vane pump unit (ModelJZJXRoots-SlidingVaneRotaryVacuumPumpSystem)
Roots pump is the main pump, and a rotary vane pump before the pump in series. Its compact structure, easy to operate. It is suitable for all kinds of real systems which need large pumping speed and high vacuum. Such as: vacuum smelting, power capacitors, transformers, vacuum impregnation, vacuum coating equipment, such as pre pumping, etc..
Zj roots vacuum pump series
(ModelZJRootsVacuumPump) is a kind of rotary type variable capacity vacuum pump to have before the pump with the side can be used in a wide range of pressure has a large pumping speed of the pumping gas in the dust and water vapor is not sensitive to widely used in metallurgy, chemical, food, electronic coating and other industries.
HIB--SZ series chemical resistance ceramic water ring vacuum pump
In the use of the process often encountered in the delivery of chemical gas, which requires the introduction of new concepts of corrosion resistance vacuum pump. It is by this special ceramic medium did part of the flow, the real line with the usual "wear resistant, acid and alkali resistance, high temperature resistance" requirements. This model is a new product recently introduced by Shanghai.
2BA series direct coupled water ring vacuum pump
2BA type water ring vacuum pump is a new generation of water ring vacuum pump, which is based on the original SKF type and 2FA type water ring vacuum pump. It has advanced design, novel structure, and is suitable for all kinds of hard and complex applications. It can be suction contains a lot of moisture, condensing medium, pumping flammable, explosive or toxic, corrosive gases when less prone to danger, so it can be widely used in machinery, petroleum, chemical, power, pharmaceutical, food, ceramics, sugar refining, printing and dyeing, metallurgy, plastics, tiles, leather and other industries, especially for use in matching plastic and 2BA type water ring vacuum pump were substituted SZ, SK, 2SK-3, 2SK-6, 2S-185, 2SK-230 and W type reciprocating vacuum
