The water pump is an electromechanical device widely used in civil and industrial fields, and mainly plays a role of pumping fluid at a low-level end to a high-level end when in work (for example, pumping a liquid working medium into a high-level processing device through the water pump and a pipeline). In industrial production, in order to satisfy the water level height and the pressure automatic control needs, current water pump generally sets up a pressure switch in its outlet pipeline side, and pressure switch's signal output part and signal input part such as PLC are connected, and the during operation, when the water pressure that goes out the pipeline side is less than the water pressure signal that PLC set for, the water pump work, the water pump stop work when being higher than the water pressure that PLC set for.

Because the PLC and the like are adopted to control the operation of the water pump, the PLC has the problem of high cost and can increase the cost of the whole equipment. And more importantly, the working mode that the PLC controls the water pump based on the water pressure switch is adopted, under the actual condition, if the water level switch has poor detection sensitivity due to quality problems or long service time, due to the fact that signals input to the PLC are abnormal, the water level and the water pressure pumped out by the water outlet pipeline of the water pump cannot be guaranteed to reach the required height and pressure, and further normal production is affected. For example, the water pressure switch works normally, the water pressure output by the water pump is 0.3Mpa, theoretically, the height of conveying water can reach 30 meters, when the water pressure switch works abnormally, the water pressure at the side of a water outlet pipeline of the water pump is only 0.2Mpa, but the detection sensitivity of the water pressure switch is poor, the signal voltage output to the PLC is large, and the representative water pressure is 0.3Mpa, under the actual condition, the water pump stops working when the water pressure at the side of the water outlet pipeline is about 0.2Mpa, and water is not pumped out any more (the water level height is in direct proportion to the water pressure, the water pressure is high, the water level is high, the water pressure is low, and the water level is low), so that water shortage of high-level production equipment. In addition, in the prior art, the working mode of controlling the water pump is generally manually controlled on site through a power switch, and the water pump cannot be controlled to work or stop working at a remote end by a user, so that the application has limitation.

In the application of the novel water pump, in the initial state, no water enters a high position in the pipeline 5 of the water equipment in the production area, or no water enters the pipeline 5 but does not enter the cylinder 101 (in this case, even though the water just enters the lower end in the rear cylinder 10, the magnet CT is pushed to move upwards less, but the magnet CT is not close to the reed switch GH, so the water pressure is not very large, namely the height of the water level pumped by the water pump is just higher than about 2 meters of the pipeline, the subsequent water level is not increased any more, so the water pressure is not very large, the electric energy is not wasted), the elastic acting force of the spring 102 can push the magnet 103(CT) to be positioned at the bottom dead center in the cylinder 101, so the magnet CT is just level with the position of the reed switch at the lower end outside of the cylinder 101, the magnetic acting force can act on the reed switch GH, the movable contact and the static contact inside the reed switch, like this, the anodal reed switch GH that the 12V power can be closed through the contact gets into the anodal power input end of relay J, and relay J gets electric actuation its control contact end and normally open contact end closure, because, two contacts under relay J control contact end and the normally open contact end and the first wireless signal transmission button S1 of wireless transmitting circuit finished product A3 connect respectively, so, wireless transmitting circuit finished product A3 can launch wireless closed signal this moment. In the novel water pump, when the subsequent water pump M works by power, water is pumped into the upper end of the pipeline 5 of the high-level production equipment, the water can also enter the cylinder body 101, when the water pressure is too high and the water flow is too large, and the water enters the pipeline, the water pressure can push the rubber piston 109 to overcome the elastic force of the spring 102 to drive the magnet CT to move upwards to be positioned at the upper part in the cylinder body 101 (the rubber piston 108 is positioned at a dead point position after the spring 102 is compressed and tightened, because the lower end of the cylinder body 101 is higher than the upper end of the pipeline by about 2M, the water pressure already pushes the rubber piston 109 and the magnet CT to the upper dead point in the cylinder body 10, namely, the water level is far higher than the height of the pipeline 5, at the moment, the water pressure is undoubtedly too large, the water pump M works continuously under the condition, or the water pump M is still in a working state after a water valve for the pipeline of the production equipment is closed, like this, magnet CT just maintains an equal level with the tongue tube GH1 position that is located barrel 101 outside upper end, and magnetic force can act on tongue tube GH1, the inside movable contact and the stationary contact of tongue tube GH1 are closed, and like this, the 12V power positive pole can get into relay J1 anodal power input end through contact closed tongue tube GH1, relay J1 gets electric actuation its control contact end and normally open contact end closure, because, relay J1 control contact end and normally open contact end and wireless transmitting circuit finished product A3 'S second wireless signal transmission button S2' S two contacts are connected respectively, so, wireless transmitting circuit finished product A3 can launch wireless open circuit signal at this moment.

As shown in fig. 1, 2, 3 and 4, in the novel application, in an initial state, a wireless transmitting circuit finished product A3 transmits a wireless closing signal, after receiving the wireless closing signal, a wireless receiving circuit finished product a2 outputs a high level, reduces the voltage and limits the current through a resistor R, enters a negative power input end of a relay J2, then the relay J2 is powered to work, three control power input ends and three normally open contact ends of the relay J2 are respectively closed, as the 380V three-phase alternating current power supply is respectively connected with the three control power supply input ends of the relay J2, the three normally open contact ends of the relay J2 are respectively connected with the three power supply input ends of the water pump M, therefore, in the initial state, the water pump M can work by electricity to pump water into the upper end of the pipeline 5 of the high-level production equipment, under the state that the water quantity is too little and the water pressure is too small, the water pump M can work electrically, and the water pump M can be ensured to pump water into the high-level production equipment 5. In the novel water pump, when a subsequent water pump M works with power, water is pumped into the upper end of the pipeline 5 of high-level production equipment, when water pressure is too high and water flow is too large, a wireless transmitting circuit finished product A3 transmits a wireless open-circuit signal, and after a wireless receiving circuit finished product A2 receives the wireless open-circuit signal, 4 feet of the wireless receiving circuit finished product A2 stop outputting high level, so that three control power supply input ends and three normally open contact ends of a relay J2 stop working after power failure, and the water pump M stops working, so that the water pump M is prevented from continuously working under the condition of too high water pressure and too large water flow, or after a water valve of the pipeline 5 of the production equipment is closed, the water pump M is still in the working state to cause electric energy waste (after the water valve is closed, because water in the pipeline 5 does not flow out any more, the water pumped out by the; when the water pump M stops working and the production equipment continues using water, and water level in the pipeline 5 is reduced and does not enter the cylinder 101 any more, then, the elastic acting force of the spring 102 can push the magnet 103(CT) to be located at the bottom dead center in the cylinder 101 again, the magnet CT is leveled with the position of a reed pipe GH located at the lower end of the outer side of the cylinder 101, a movable contact and a static contact in the reed pipe GH are closed again, a wireless closed signal is emitted again by a wireless emitting circuit finished product A3, the water pump M is electrified again to work, and production water is guaranteed. Through effects such as above-mentioned circuit and equipment, this is novel need not PLC and combines the working method of pressure switch control water pump, and whole equipment cost is low. Real-time water pressure in the pipeline 5 that links to each other with the water pump outlet pipe is gathered in real time through water pressure detection equipment, can also reach energy-conserving purpose under the high-order production facility water use prerequisite of fully provided (the water pressure of carrying is too high, the continuous operating time under the water pump high water pressure is longer, represents that the water pump is power consumptive big more, the electric energy will be wasted so), this novel water pressure detection equipment simple structure is compact, difficult break down, uses more reliably, provides favourable technical support to normal production. When the heights of two reed switches GH and GH1 arranged in a plastic shell 107 are adjusted before use, the reed switch GH is adjusted to the lowest position outside a cylinder 101 (no adjustment is performed later), the reed switch GH1 is adjusted to the highest position outside the cylinder 101, then a valve of a pipeline 5 of production equipment is closed, a water pump M pumps water into the cylinder 101, after a magnet CT and a rubber piston 109 overcome the elastic action of a spring and rise to a top dead center of a compression spring in the cylinder 101, the reed switch GH1 is slowly adjusted downwards along the outside of the cylinder 101, when the contact inside the reed switch GH1 is just adjusted to be closed, a wireless transmitting circuit finished product A3 transmits a wireless open-circuit signal, after the water pump M stops working, the position of the reed switch 1 is required, when the subsequent water amount is too large and the water level is too high, the wireless transmitting circuit finished product A3 transmits the wireless open-circuit signal, the water pump M stops working (if the reed switch GH1 is adjusted downwards, when the water pressure is relatively low, the water pressure pushes the magnet CT to rise to the position below the middle part in the cylinder body, and the water pump M stops working, so that the energy-saving purpose is achieved). After the novel primary adjustment, any adjustment is not needed under the general condition. This novel during operation can guarantee that water pump M pumped just is higher than the production area after water equipment pipeline 2M, water pump M just stop work, prevents to continue work and causes the extravagant electric energy of water pump M (when not having the water valve that links to each other with production area water equipment pipeline 5 after the production very much, energy-conserving effect is more obvious).

As shown in fig. 1, 2, 3 and 4, when a user needs to turn off the water pump M at a far end, the user can respectively send out control commands through the mobile phone APP and the wireless mobile network at any place of the far end through the existing mature mobile phone APP technology, when the user needs to control the water pump M to stop working, the user sends out a first wireless control command through the mobile phone operation interface, after the mobile phone remote control circuit module a4 receives the control command, the first control power output terminal pin 3 will output power to enter the positive power input terminal of the relay J3, so the relay J3 is powered on and opens the control power input terminal and the normally closed contact terminal thereof, because the control power input terminal of the switch power supply a1, the normally closed contact terminal and the positive power input terminal of the relay J2 are connected through the relay J3, the relay J2 is powered off and no longer closes the three control power input terminals and the normally closed contact terminals thereof at the moment, thus, even if the wireless transmitting circuit finished product A3 transmits a wireless closing signal, the water pump M does not work; when a user needs to control the water pump M to work, a first path of wireless open-circuit instruction is sent out through a mobile phone operation interface, after a mobile phone remote control circuit module A4 receives the control instruction, the 3 pins of the first path of control power supply output end stop outputting power to enter the positive power supply input end of the relay J3, then, the relay J3 loses power and does not attract the control power supply input end and the normally closed contact end to be closed, thus, the 12V power supply positive electrode output by the 3 pins of the switch power supply A1 passes through the control power supply input end of the relay J3 and the normally closed contact end enters the positive power supply input end of the relay J2, after a wireless transmitting circuit finished product A3 emits a wireless close signal, the relay J2 gets power to attract the three control power supply input ends and the three normally closed contact ends to be closed, and therefore. The water pump M can be controlled by a user at a far end through a mobile phone to work or not work, and the use is more convenient.

As shown in fig. 3 and 4, the resistance R is 1K; the model of the NPN triode Q1 is 9013; relays J, J1, J3 are DC 12V relays; relay J2 is a DC6V relay having two power inputs, three control power inputs, three normally open contact ends, and three normally closed contact ends (not used); reed switches GH and GH1 are normally open contact type reed switches with glass shells of Hengcw and ORT 233.
