Description

Electromagnetic water pump

Technical field

The utility model relates to a kind of Electromagnetic water pump.

Background technique

The working principle of Electromagnetic water pump is to utilize electromagnetic force to promote and the to-and-fro motion of generation pump core, cooperates related valve to realize the pump water function again under different closure or openness, and actual is exactly a kind of reciprocating pump, and motive force is electromagnetic force.Owing to generally be provided with unidirectional stop valve at delivery side of pump in actual the use, when output tube stops up or pressure is excessive fails timely release, or when big pressure appears in the connection internal tank of output terminal, offset with pressure in the pump, cause unidirectional stop valve to be difficult to be opened, water flow is less than normal; The extraordinary increase of pump internal pressure also causes accident easily, so safety in utilization is lower.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides that a kind of practicability is stronger, the better Electromagnetic water pump of Security.

The purpose of this utility model is achieved in that a kind of Electromagnetic water pump, comprise the pump main body that promotes control pump core back and forth movement by electromagnetism, the pump main body is provided with the inlet opening and is built-in with the output tube of unidirectional stop valve, and it is characterized in that: the output tube of described pump main body is provided with an overvoltage overflow mechanism.

Described overvoltage overflow mechanism is arranged at the outside of corresponding unidirectional stop valve position on the output tube.

Described overvoltage overflow mechanism comprises the spill pipe that communicates with output tube of being located at the outside, corresponding described unidirectional stop valve position, the spring that is provided with needle in the spill pipe and applies the power of pointing to the output tube direction to needle.

Described overvoltage overflow mechanism be run through the output tube tube wall often open the overflow micropore.

The pump core of described pump main body runs through in the pump chamber, and two ends are connected with spring, and pump chamber is arranged with field coil outward, and this field coil is connected with diode.

Also being provided with on the described pump main body can be for the fixing slot of controlling the automatic temperature control apparatus of on/off.

The utility model is by being provided with the overvoltage overflow mechanism, the working pressure of guaranteeing the pump housing is in the security clearance scope, prevent that because output tube stops up or pressure is excessive unidirectional stop valve fails timely release and contingent accident, Safety performance strengthens greatly, the utility model is movable sensitive simultaneously, pump core motion frequency is higher, and the specific discharge of pump is bigger.

Embodiment

As Figure 1-3, the utility model is a kind of Electromagnetic water pump, comprise pump main body by electromagnetic force control pump core back and forth movement, the pump main body is provided with the inlet opening and is built-in with the output tube of unidirectional stop valve, is made up of around axle 12, coil case 13, regulating ring 14, packing ring 15,

valve

16,22, fixing plug 17, valve gap 18, needle 19,

seal ring

20,21, field coil 23, diode 24 etc. housing 1, power pin 2,

spring

3,4,6,7,8, pump core 5, magnetic rings 9, pump chamber 10, output tube 11, coil.

Coil twines field coil 22 outside axle 12 after, the socket coil case 13 again, are installed on housing 1 inside.Pump chamber 10 passes the hollow channel of coil around axle 12, and fixing by magnetic rings 9 and regulating ring 14.Pump core 5 runs through pump chamber 10, and two ends are respectively equipped with

spring

3,4, and after the energising, pump core 5 is front-rear reciprocation movement (promotion) under the acting in conjunction of electromagnetic force and spring.Pump core 5 front end sleeves are connected to packing ring 15 and

seal ring

20,21, are used for location and sealing.Pump core 5 front ends stretch in the output tube 11.In the output tube 11 flange is arranged, the flange both sides are respectively equipped with rubber valve 16, spring 7 and rubber valve 22, spring 6.Spring 7 produces active force makes rubber valve 16 terminations prop up the outlet of pump core 5.Spring 6 produces active force makes rubber valve 22 terminations prop up output tube 11 inward flanges, forms unidirectional stop valve.

On the output tube 11 of pump main body, be provided with an overvoltage overflow mechanism, comprise the spill pipe that communicates with output tube 11 of being located at corresponding above-mentioned unidirectional stop valve position outer side surface, being provided with head in the spill pipe is the needle 19 of taper and the spring 8 that applies the power of pointing to output tube 11 directions to needle 19, through hole between spill pipe and the output tube 11 is closed by needle 19 heads, when pressure is excessive, needle 19 is backed down get final product release.The overvoltage overflow mechanism also can not be provided with needle and pressure spring, but only run through an overflow micropore of often opening at output tube 11 tube walls, output tube 11 is communicated with spill pipe, come pressure in the balance pump chamber 10 by the appropriate continuous overflow of overflow micropore of this pore size design, also can reach same relief function, make it to be in a safe condition.

On field coil 23, also be connected with diode 24, make field coil 23 added working powers be actually Ac, so the reciprocating frequency of pump core can reach (in mains frequency 50/60Hz) 50～60 times/second through the power supply after the one way rectifier.

The field coil shell 13 of pump main body also is provided with the slot of settling the automatic temperature-adjusting control unit; in order to whenever necessary; insert automatic temperature-adjusting control unit 25; be plugged in the slot between the two; can control on/off according to the temperature of setting, in the present embodiment, when temperature surpasses 105 ℃; control gear 25 makes the circuit disconnection make the pump outage and quits work, and can not burn because of overheated thereby play the protection pump.

When pump core 5 when the inlet opening direction moves, form the valve 16 that negative pressure is opened pump core front end, water is inhaled into pump chamber 10 short stays; When pump core 5 when output tube 11 directions move, pump core front end valve 16 is closed, the water storages in the pump chamber 10 are compressed, and wash the rubber valve 22 of output tube 11 open, unidirectional stop valve is opened, water is flowed out by output tube 11, has so just finished pump water process No. one time.Relating to parameters such as the capacity of the main and pump chamber 10 of the flow of pump, the number of turn of field coil 23 and working pressure; Also relevant with the influence of the action sensitivity of material of pump core (be desirably pure iron most, also can use material to replace) and respective valves and sealing effect with approximate speciality, can be according to actual conditions design and adjustment.

The utility model can vertically be installed or level is installed (as shown in Figure 2), and output tube leads to watering equipment; The inlet opening is by flexible pipe (as PVC, PE or silicon flexible pipe) water receiving case, and the overvoltage overflow mechanism also can connect recovery tank or other containers by flexible pipe.
