QJB Type Submersible Mixer Suitable for industry

QJB Type Submersible Mixer Suitable for industry

Product Description

QJB  type  Submersible  Mixer,a  key  equipment  used  in  the  water  treatment  technology,can  meet  the  technological requirement for homogeneity and ffuidity of solid-liquid two-phase flow and  solid-liquid-gas three phase  flow in biochemical course  of  the  water  treatment  process.It   is  composed  of  the   submersible  motor,impeller,and  installation  system  etc..The submersible mixer is in direct connection structure.Comparing with the traditional high-power electric motor that retards speed by  a  speed  reducer,it  is  highlighted  by  compact  structure,low  energy  consumption,facile  maintenance.The  impeller shaped   by   finishing   casting   or   punching,which   has   high   precision,forceful   thrust   as   well   as   simple,nice-looking   and streamlined profiling.The  series  of products  are  applicable  to  the  places  that  requires  for  solid-liquid  agitating  or  mixing.

QJBA type submersible mixer is a type of energy saving products,supporting by the  conventional  four-motor  and high-efficiency reducer,compared to Multi-motor can significantly reduce the power of burden,can be saving energy more than 15%.

QJBY type submersible mixer is a new product of ultra high efficiency.The self starting permanent magnet motor is used It is asynchronous start synchronous operation,simple structure,stable operation,high power factor,and easy speed regulation. Motor efficiency can meet I class energy efficiency of the national standard (GB18613-2012),or IE4 energy efficiency of international standards (IEC60034-30).

Scope ofApplication

The submersible mixers are mainly used for mixing,agitating and making ring flows in the process of municipal and industrial sewage treatment and can also be used for equipment maintenance of the landscape water circulation through agitation,they can achieve the function of creating water flow,improving water quality,increasing oxygen content in the water and effectively preventing the sedimentation of the suspended substances.

Conditions of Application

In  order  to  ensure  the  normal  operation  of the  submersible  mixer,please  make  correct  selection  of the  operating environment and the operating modes.

The highest temperature of the medium shall not exceed 40℃;

The scope of pH value of the medium:5~9;

The density of the medium shall not exceed 1150Kg/m³;

The depth of submersion shall not exceed 20m.

▲Special Warning:The submersible mixer must completely submerse in the water and cannot operate in the inflammable, explosive,highly corrosive and high-temperature environment.In line with the requirement of the special environment,our company can provide special design for the users.

Reference for Type Selection

The type  selection  of submersible mixer is a rather complicated job.The correctness of the type  selection will  directly  affect the  normal  usage  of  the  equipment.The  principle  for  the  type  selection  is  to  enable  mixer  to  give  full  play  to  its  mixing function  in the  appropriate  volume.This  standard  can  generally  be  determined  by the  flow  velocity.In  line  with the  different technological  requirement  of  the  sewage  treatment,the  optimum  flow  velocity  for  the  mixer  type  selection  shall  ensure  the velocity  range  of  0.15~0.3m/s.In  case  of  the  flow  velocity  lower  than  0.15m/s,the  effectiveness  of  agitation  or  mixing  can not  be  achieved.In  case  of  the  flow  velocity  bigger  than  0.3m/s,the  technological  effectiveness  will  be  affected  and  waste will be  caused.Therefore,before type  selection,it  is  necessary  to  determine what kind  of environment the mixer will be usedin,for  instance,sewage  ank,slag  pond  or  biochemical  pond.Secondly,the  parameters  of  the  medium  such  as  content  of  the suspended  substances,temperature,pH  value  as  well  as  the  shape  of the  pond,water  depth  and  even  the  mode  of  installation and so on will all influence the type selection.Meanwhile,it is also necessary to consider the energy-saving factor,because this will influence the operating cost of the users in the future.

For the purpose of fulfilling the optimum mixing function in different environments,we can supply multiple types of the submersible mixers to the users and provide type selection service as well.
