State 53 discharge of constant temperature liquid outlet.The constant temperature liquid can be coolant liquid, be also possible to high-temperature liquid, so that in the electromagnetic pump
Conveying solution is maintained at the temperature of setting, prevents conveying solution boils or crystallization.
The cylindrical setting of the shell 50, and the shell 50 in the radial direction, the constant temperature liquid import 52 with
About the 53 constant temperature liquid outlet shifts to install.Specifically, from the point of view of direction shown in FIG. 1, the constant temperature liquid import 52 is leaned on
Nearly 2 side of the outlet pipe sleeve setting, and it is located at the top of the enclosure of pump head 1, the constant temperature liquid outlet 53 is close to described fixed
The setting of position 6 side of pressing plate, and it is located at the lower section of the enclosure of pump head 1, thus after constant temperature liquid self-constant temperature liquid import 52 flows into, it can be with
Entire accommodating chamber 51 is flowed through, then from 53 outflow of constant temperature liquid outlet, so set, constant temperature liquid can be made to be full of entire accommodating chamber 51,
And then the significantly more efficient conveying solution made in electromagnetic pump is maintained at set temperature.Certainly, the constant temperature liquid import 52 and constant temperature
The setting position of liquid outlet 53 can also be adjusted according to actual needs, as long as meeting keeps the conveying solution in electromagnetic pump
In this requirement of set temperature, not limited in this.
It please refers to shown in Fig. 3 to Fig. 5, below with reference to Fig. 3 to Fig. 5 to the feed liquor process of electromagnetic pump of the invention, out liquid
Process and constant temperature liquid flow process are described in detail.
Feed liquor process: as shown in figure 3, when magnet coil 41 be powered when, iron core slide bar 32 can under the action of electromagnetic force to
Right movement, power spring 31 are compressed, and limit spring 33 is stretched, meanwhile, import check valve 14 follows iron core slide bar 32 to the right
Movement, one end of import return spring 15 also follow import check valve 14 to move right, and import return spring 15 is stretched, this
When, between import check valve 14 and Outlet check valves 16 for receiving conveying solution accommodating cavity volume be gradually increased, chamber
Interior pressure is gradually reduced；When the pressure at the pressure in accommodating cavity is less than inlet 34, import return spring 15 can in pressure
It hauls import check valve 14 under the action of difference to move downward, import check valve 14 is opened at this time, work of the conveying solution in pressure difference
With lower by first cavity 30 and the second cavity 320, and enter in the accommodating cavity；When conveying solution is all introduced into
After in accommodating cavity, the pressure in accommodating cavity is identical as the pressure at inlet 34, at this point, import check valve 14 is in import return bullet
It is moved right again under the action of spring 15, until being connected with iron core slide bar 32, and seals the second sky of the iron core slide bar 32
One end of chamber 320.
Liquid process out: as shown in figure 4, when magnet coil 41 powers off, electromagnetic force disappears, and iron core slide bar 32 is in power spring
It being moved downward under 31 elastic force effect, 33 return of limit spring is simultaneously compressed, meanwhile, import check valve 14 and import return spring
15 also follow iron core slide bar 32 to move downward, and import return spring 15 is compressed, at this point, being located at import check valve 14 and outlet list
To the accommodating cavity volume for receiving conveying solution between valve 16 is gradually reduced, cavity pressure is gradually increased；When in accommodating cavity
When pressure is greater than the pressure at outlet 2 upper liquid outlet 22 of pipe sleeve, Outlet check valves 16 can be forced to the left under the action of pressure difference
Movement, Outlet check valves 16 are opened, and outlet return spring 17 is compressed, at this point, the conveying solution in accommodating cavity is in pressure difference
Effect is lower to be discharged by the third cavity 12 and the 4th cavity 21, and from the liquid outlet 22；When conveying solution is all discharged
Afterwards, the pressure in accommodating cavity is identical as the pressure at liquid outlet 22, at this point, bullet of the Outlet check valves 16 in outlet return spring 17
It is moved right under power effect, until being connected with the lateral wall of the pump head solution cavity 121, and seals the pump head solution cavity
121 one end.
Constant temperature liquid flow process: as shown in figure 5, constant temperature liquid enters the accommodating chamber 51 from constant temperature liquid import 52；Then, permanent
Warm liquid flows through entire accommodating chamber 51 along the inner wall of the accommodating chamber 51；Finally, constant temperature liquid is flowed out from constant temperature liquid outlet 53.It needs
Illustrate: in the flow process of constant temperature liquid, constant temperature liquid import 52 and constant temperature liquid outlet 53 are disposed as through type, so that
Constant temperature liquid is always flowing, to make the constant temperature liquid moment full of entire accommodating chamber 51, and then can use constant temperature liquid band
It walks motor and generates the heat for increasing loss with the extra heat in outside air or for conveying solution, make defeated in electromagnetic pump
It send the solution moment to be maintained at set temperature, prevents conveying solution boils or crystallization.
The addition time point design of constant temperature liquid: 1, feed liquor process progress before it first can be added constant temperature liquid and make constant temperature
Liquid stream moves up；2, constant temperature liquid can be added while feed liquor, make to convey solution flowing synchronous with constant temperature liquid.The skill of this field
Art personnel can select according to the actual situation, as long as can guarantee that conveying solution is maintained at set temperature.
On the one hand electromagnetic pump of the invention provides conveying power using electromagnetic coil mould group 4, be not only simple in structure, and
Substantially reduce the volume of entire electromagnetic pump；On the other hand, by the way that limit spring 33 is arranged in the first cavity 30, in third sky
Setting import return spring 15 and outlet return spring 17 in chamber 12, so as to greatly improve the linear essence of conveying liquid inventory
Degree and steady state accuracy.Electromagnetic pump of the invention can be designed to convey the model of smaller flow, super to meet type of researching and analysing
Critical extraction equipment pump, certainly, electromagnetic pump of the invention can be applied not only to supercritical extraction unit and refrigeration system, also
It can be applied in various mini domestic electric appliances, the scope of application is wider.
In conclusion electromagnetic pump of the invention by the outside of enclosure of pump head 1 be arranged thermostatic assembly 5, thus constant temperature liquid
It can be entered in the accommodating chamber 51 from the constant temperature liquid import 52, then by the accommodating chamber 51, finally from the constant temperature liquid
53 discharge of outlet, constant temperature liquid can take away motor generation and the extra heat or molten to convey in outside air while discharge
Liquid increases the heat of loss, makes electromagnetic pump keep solution in the temperature of setting in conveying easily vaporization or easy crystallization solution, prevents
Vaporization or crystalline polamer are generated, service performance and the service life of electromagnetic pump are substantially increased.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to preferred embodiment to this hair
It is bright to be described in detail, those skilled in the art should understand that, it can modify to technical solution of the present invention
Or equivalent replacement, without departing from the spirit and scope of the technical solution of the present invention.
