The controller is SCM Based control circuit or PLC programmable controller, as shown in figure 12, in water pump
When work, controller is respectively to three corresponding control electric currents of electromagnet input.Specifically, being pushed away the stage under piston, controller
It controls third electromagnet and the second electromagnet is powered and generates opposing magnetic field, piston moves downward for magnetic field repulsive force promotion, in the second electricity
When magnet is moved to extreme position(Electromagnet conduction time is set by controller), controller control third electromagnet temporarily break
Electricity, controller controls the first electromagnet and the second electromagnet is powered and generates opposing magnetic field, and it is downward that magnetic field repulsive force pushes piston to continue
Movement, when third electromagnet powers off, the guiding plush copper of the second electromagnet is stuck in the V-shaped positioning surface position on locating channel, will not
It moves up;The stage is pulled up in piston, controller controls the first electromagnet and the second electromagnet is powered and generates magnetic field in the same direction, magnetic field
Gravitation drives piston upwards, and the guiding plush copper on the second electromagnet is moved to the second positioning port position at this time, until the first electricity
Magnet and the second electromagnetic actuation to together when, controller control third electromagnetism iron channel generates the magnetic led to the second electromagnet
, gravitation driving piston in magnetic field continues up.
Due to pulling up the stage in piston, especially the second half forms stronger magnetic field since three electromagnet are powered simultaneously
Power can effectively drive piston upwards.The water pump is particularly suitable as suction pump, can be the water of lower position or other
Liquid is pumped toward a high position.
The signal of Hall sensor 97 there are one being installed in the lower part outer wall of the pump case, Hall sensor and controller is defeated
Enter end electrical connection.
The operation principle of the water pump is such, when the first electromagnet is moved down into extreme position, hall sensing
Device detects that signal, controller obtain the first electromagnet from the total time spent during the lowermost is topmost moved to, then
In next cycle, controller controls time of the driving current of each electromagnet according to being used as the total time with reference to being set
It is fixed.--- piston is from being topmost moved to the lowermost total time and the pressure size outside water pump water outlet valve is proportional.Such as water
When pumping just startup work, during piston moves downward, third electromagnet is driven, the current time of the first electromagnet is 3s, drive
The current time of dynamic second electromagnet is 6s;And Hall sensor detects that the first electromagnet is moved to the lowermost time and is
4s, then at next period, driving third electromagnet, the first electromagnet current time be changed to 2s, the second electromagnet of driving
Current time is changed to 4s;Piston during the upward movement, the first electromagnet, the second electromagnet be powered be also set to total time
It is identical as the time that piston moves downward.
