2SK series water ring vacuum pump for vacuum evaporation, vacuum drying

2SK series water ring vacuum pump for vacuum evaporation, vacuum drying
Product Detailed
1.Easy to installation and save time .2. Reduce pollution 3.reduce the liquid consumption

Introduction:The water ring vacuum pump is widely used in chemical industry and pharmaceutical fields for its working principle and structural features. Under the normal application condition, the working liquid of water ring vacuum pump adopts the method of direct drainage. The water drain into the large cyclic pond or discharged out directly. This way of water supply and drainage is convenient and simple so it is used in the most practical situations. However, if the being pumped medium contains the organic solvents or toxic substance, directly drainage has some disadvantages as following: 1, When the water ring vacuum pump works, the being pumped gases and the working liquid are mixture, so the discharged water contains parts of organic solvent and toxic substance, the more discharged water, the heavier pollution to the environment.2,The water contain organic solvents or toxic substance will release the harmful gases and increase the environment pollution. 3, The being pumped organic solvents are not easy to recycle and lead to lots of waste.

For the above reasons, more and more chemical and pharmaceutical enterprises adopt 2BW series water ring vacuum pump closed circulation system.  

 Main features:1, This system is whole set to supply, including separator, heat-exchanger, pump frame, inside pipes and so on, it is easy to installation and save time.2, Working liquid can use water or various chemical reagents which can reduce the pollution to the environment. 3, If the working liquid is the suction medium, then the medium can be recycled. 4, 2BW series closed ring system is designed under the entrance conditions, cooling water conditions, exhaust port conditions and it belongs to the non-standard product.

 Operational principle:

The primary 2BW series liquid ring vacuum pump/compressor closed circulation system as the picture shows: The being pumped gas enters into the liquid ring vacuum pump/compressor through the suction port, the compressed gas and parts of working liquid flows to the separator. The gas and liquid are divided in the separator, the gas goes out from the exhaust port, and the working liquid through the heat-exchanger inhaled recycling by liquid ring pump/compressor for recycling.Liquid ring pump will produce heat in the process and the main heat includes: vacuum pump/compressor non-efficient power, the heat from the high temperature of the suction gas; the heat discharged from the compressed gas. The main function of the heat-exchanger is cooling water, in order to keep the temperature of the working liquid within the reasonable range.

Equipments: liquid ring vacuum pump/compressor closed circulation system main components include:    1, liquid ring vacuum pump/compressor   2, separator   3, heat exchanger   4, common chassis   5, internal pipesThe following accessories can be choose according to the practical situation:     1, Non-return valve     2, Vacuum meter or pressure transducer     3, The filter      4, Overflow port.     5, Replenish liquid port.    6, Level meter.      7, The pressure meter    8, Thermometer.     9, Booster pump.     10, Control valve.     11, Cavitation protection pipe.      12, If it works as the compressor, balance pipes and the relevant valve accessories should be installed between the suction and exhaust pipes.    13, Suction pipe, exhaust pipe, shutoff valve of the working liquid pipe.     14, Exhaust condenser      15, Other accessories can be installed for special requirements.    2BW series system is made up of 2BV or 2BE series liquid ring vacuum pump, separator, heat exchanger and other pipe accessories. Compared with the single liquid ring vacuum pump, the installation of the system is more convenient. Because of the liquid circulated to use the system can greatly reduce the liquid consumption and the environment pollution. So the advantages are outstanding when being pumped gases contain organic solvents and toxic substance. Actually 2BW series system is widely used in many conditions. The working liquid of the system can use various mediums .such as the water, methanol , alcohol, dimethylbenzene, anilin, acetone and other organic solvents etc.

The gas is inhaled by flange N1.2  The gas is compressed and part of working liquid are mixture, through the exhaust pipe (170)and flows to separator(080), the mixture is divided in the separator. The compressed gases go out the system through flange N2.2, Separator (080) is equipped with level meter (230) which indicates the liquid level. The normal level is limited from the max. to the min.(determined by the visible scope of the level meter). If the level is too low, the liquid will be supplied through the port N3.3.If the level is too high, the liquid will be discharged from the flow-off N4.2, So the level in the separator keeps a definite height by this way.  The drain port N4.6 is used to exhaust the liquid in the separator (080) and vacuum pump (010) completely.  The function of the working liquid is to form the liquid ring in the vacuum pump. The liquid passes through pipe (260) and the separator (080), and then flows into the heat exchanger. After cooling down, the liquid gets back to the pump through pipes (280). During the process, the heat produced from the compressed gases and accompanied with it is released. The closed circulation system is designed for two vacuum pumps(010) share a separator(080) and a heat exchanger(130)(one pump works, another prepares) .When one vacuum pump works, the prepared pump suction and discharge pipes of the butterfly valve must be closed. In general, the unit is made of one vacuum pump (010) and one separator (080) and one heat exchanger (130).
