What is be connected enters aquaporin C.
The operation principle of the Electromagnetic water pump is as follows：
Its operation principle is as follows：When its work exchange power supply is connected to the pump housing, by coil inside or with coil string
The rectified action of the external one-way commutation diode of connection, a cycle for putting on the alternating current power supply of coil are changed into only positive current
Or the only half-cycle voltage of negative current.When the half period in positive current or negative current, the electromagnetic force that electromagnetic system is produced
Move downward the movable core 8 of the magnetic conductivity in its activity interval, as shown in Fig. 2 the reset bullet below movable core 8
Spring 10 is compressed, now, as 9 upper outlet of branch sleeve has the positive sealing of the second check valve, while inside branch sleeve 9
The increase of pressure chamber A volumes and pressure reduces (be less than normal atmospheric pressure), promote external fluid in the effect of atmospheric pressure
By the via in the middle part of the water inlet of 1 bottom of cylindrical tube and movable core 8 and overcome in 8 mesopore of movable core first unidirectional down
Valve, and then fill up the volumetric spaces that branch sleeve 9 increases because pressure reduces.When power of the electromagnetic force on movable core 8
Equal to back-moving spring 10 compression restoring force when, movable core 8 move to maximum state, as shown in figure 3, pressure chamber now
, in the maximum state of volume, its suction fluid is also maximum for A.When another currentless half period, electromagnetic force disappears, activity
The support that iron core 8 does not have electromagnetic force is just moved in the presence of the restoring force of back-moving spring 10 upwards, as shown in figure 4, now body
The maximum pressure chamber A of product due to movable core 8 motion upwards and volume reduces, pressure chamber A volumes reduce and pressure increase, living
First check valve on 8 top of dynamic iron core is in sealing state in the presence of extension spring 13, and so, the pressure of this increase is just promoted
Fluid inside pressure chamber A is discharged from the outlet of outlet pipe 2 after overcoming the pressure of its second check valve of upper outlet.It is so all
And the work for renewing, so as to constitute the process of Electromagnetic water pump water suction and draining.
The control principle of each outlet flow of the Electromagnetic water pump is as follows：
Because every group of water chamber is all joined directly together with pressure chamber, the function all having as main water flowing out structure.
1) when the check valve inside each group water chamber is all identical, then when main flow is M, when the water flowing out structure for having N groups same
When, per group of flow is then M/N.
2) when each group water chamber internal one-way valve pressure texture is different, then the flow of the pump housing can only be from check valve dynamics
Little water chamber water outlet.If the resistance in the maximum outlet of check valve dynamics is F, its rate of discharge is N0；Check valve dynamics
Resistance in little outlet is f1, and its rate of discharge is N1, wherein F ＞ f.
When the adjustable current-limiting apparatus of one dynamics fx of outlet external series in little pressure check valve,
As fx=0, because F is ＞ f1, flow is flowed out from little pressure export, N0=0, N1=M；
As fx+f1=F, i.e. fx=F-f1, so flow is averagely flowed out from big two outlets, N0=M/2, N1=M/2；
As fx+f1 ＞ F, i.e. fx ＞ F-f1, so flow is flowed out from big pressure export, N0=M, N1=0；
When fx 0 to take arbitrary value between F-f1 when, the flow of N0 can be from 0 to arbitrary value is taken M/2.
Analyze by more than, we can be such that the rate of discharge of main flow changes from 0 to arbitrarily adjustable M.So as to reach
From a cylinder tube inlet water inlet from the purpose of multiple outlet pipe water outlets in parallel.So when the flow of the pump housing itself is one
During definite value M, the design that we are exported by N groups can make us actual and accomplish below M arbitrarily our institutes from the flow of primary outlet
The value of needs.
The foregoing is only preferred implementation of the present utility model, it is noted that for those of ordinary skill in the art
For, under the premise of without departing from principle of the present utility model, various remodeling or improvement can be carried out to this utility model, such as,
The structure of each water chamber can be differed, and such as diaphragm type electromagnetic pump etc., other only have the pump of single water flowing out structure
Class, it is also possible to increase the water flowing out structure of multigroup parallel connection, these are regarded as within protection domain of the present utility model.
