Description

A kind of Novel vortex pump

Technical field

The utility model belongs to water pump technology, is related to a kind of peripheral pump, particularly a kind of Novel vortex pump.

Background technology

The characteristics of peripheral pump is small, light-weight is in shipbuilding, light textile, chemical industry, metallurgy, machine-building, aquaculture, fixation Departments such as fire-fighting voltage stabilizing, heat-exchanger, the long-range sprinkling irrigation of agricultural etc. are all widely used.Meanwhile peripheral pump is simple in structure, casting Make and processing technology is all easier to realize, with the rapid development of information industry, the application of intelligent peripheral pump is also more and more general And.A kind of reliable in quality, easy to operate, the appearance and popularization of long-lived peripheral pump are imperative.

A kind of intelligence low noise self-priming combination pump (application number as disclosed in Chinese patent literature：201710273761.8), Including the pump housing, impeller, injector, motor, pressure sensor, water flow sensing unit and control panel；Pressure sensor is used to detect multiple The pressure change in pump is closed to trigger motor operation or stopping；Water flow sensing unit is used for the signal for detecting the current in combination pump, Whether the water i.e. in the pump housing is flowed to trigger motor operation or stopping；Control panel is used to obtain pressure signal and/or water-flow signal Data judge the control instruction that output motor starts or stops, complete the start and stop intelligent control of combination pump.

When Intelligent Composite pump works on power, first time sucks into vain, after being full of water in pipeline：

When combination pump water supply terminal is closed, pressure sensor detects that pressure rises in pump, and reaches when setting the upper limit just Signal is sent to control panel；The water-flow signal that water flow sensing unit detects at this time disappears, and the signal equally is issued to control panel；Control Making sheet closes down motor after receiving the signal for coming white pressure sensor or water flow sensing unit, and Intelligent Composite pump reaches " Guan Shuiting Machine "；

During combination pump water supply terminal unlatching water, pressure sensor detects that pressure declines in pump, and reaches setting lower limit During value just signal is sent to control panel；Water flow sensing unit detects that water-flow signal rises to setting value, water flow sensing unit from 0 at this time Signal be equally issued to control panel；Control panel opens electricity after receiving the signal for coming white pressure sensor or water flow sensing unit Machine, Intelligent Composite pump realize " being started shooting with water ".

Common water flow sensing unit substantially uses the structure of carbon-point+magnet.When water pump operation, check-valves upsprings Rise, as check-valves moves up on check-valves, the magnetic flux between carbon-point and magnet changes correspondingly magnet, wiring board sensing To the signal of flow.But this structure drawback：Carbon-point easily adsorbs the impurity in water in the energization course of work, when accumulation During a certain amount, flow sensing failure is be easy to cause.
