Fig. 1, 2 show, this is novel, and the working method of high-order production facility is gone into with low-order salt thick liquid etc. to salt thick liquid pump body 1, and current salt thick liquid pump is identical completely, and it is no longer repeated here (initial state solenoid valve DC3, DC4 lose its inside case of electricity and open, have guaranteed in the spiral case of salt thick liquid inflow outflow salt thick liquid pump body M). After the 220V alternating current power supply enters the pins 1 and 2 of the stabilized voltage supply A1, the pins 3 and 4 of the stabilized voltage supply A1 can output stable 12V power to enter the power input end of the control circuit and the power input ends of the storage battery G, the control circuit is in a power-on working state, and meanwhile, the 12V power supply output by the stabilized voltage supply A1 carries out floating charging on the storage battery G, so that the storage battery G keeps good electrical storage performance and cannot be overcharged and damaged (after the stabilized voltage supply A1 is de-energized, a rear-stage circuit can also work normally). The operating personnel opens the switch of salt slurry pump body M at every turn, after the salt slurry pump body M got the electricity, when constant voltage power supply A1 power input both ends got the electricity, relay K1 can get the electricity actuation its control power input end and normally closed contact end open a way, the 12V power positive pole of battery G output can not pass through relay K1 control power input end and normally closed contact end like this, get into relay K2 anodal power input end and relay K's control power input end, follow-up time control switch A2 can not get the electricity work, salt slurry pump body M is in normal operating condition. The salt slurry pump body M is used up at every time, after an operator closes a power switch of the salt slurry pump body M, the power switch S1 (the internal contact of the power switch S1 is opened, the power input end of a stabilized voltage power supply A1 and the relay K1 lose power simultaneously, the 12V power anode output by the storage battery G can pass through the relay K1 control power input end and the normally closed contact end, the power switch S1 enters the relay K2, the positive power input end (and the control power input end) of the K, then, the relay K2, the K is electrified and attracted, the control power input end and the normally open contact end of the relay K2 are closed, and the control power input end and the normally closed contact end of the relay K. Because the normally open contact end of the relay K2 is connected with the positive power input end of the time control switch A2, the time control switch A2 can work electrically at the moment, after the time control switch A2 works electrically, under the action of the internal circuit of the time control switch A2 and the power output time of 3 and 4 pins set by technicians, the power of 3 and 4 pins can be output for 15 seconds and enters the two power input ends of four electromagnetic valves DC1, DC2, DC3, DC4 and the relay K3, so that the internal valve cores of the electromagnetic valves DC3 and DC4 are powered electrically and are closed, and salt slurry is prevented from flowing into and flowing out of a volute of the salt slurry pump body M; after the electromagnetic valves DC1 and DC2 are powered on, the internal valve cores are opened, so that tap water with pressure outside can flow into the volute from the water inlet branch pipe 102 and flow out from the water outlet branch pipe 103 into the wastewater tank, and the tap water flows in and out to flush the interior of the volute and the impeller; the relay K3 gets electric actuation back its three control power input end and three normally open contact end closed, and in 15 seconds like this, the 380V power can get into salt stuff pump body M's power input end, and salt stuff pump body M gets electric work, drives volute inner impeller and rotates, and the running water that flows in like this and flows out in the volute can play better cleaning performance to parts such as volute and volute inner impeller. Through above-mentioned circuit and mechanism combined action, operating personnel closes behind the switch of salt stuff pump body M at every turn, by the way open switch S1 (operating handle is located outside the trompil before the component box), this novel just can carry out 15 seconds clear water to wash in the spiral case automatically, 15 seconds after, time control switch A2 stops output power, four solenoid valves DC1, DC2, DC3, DC4 and relay K3 are whole to lose electricity, solenoid valve DC3, the inside case of DC4 is opened, solenoid valve DC1, DC2 case is closed, can normally use salt stuff pump body M again next time (before opening the switch of salt stuff pump body M next time, close switch S1 by the way).

In the prompt circuit shown in fig. 2, in an actual situation, if an operator does not turn on the power switch S1 after the salt slurry pump body M is shut down, the power output from the normally closed contact end of the relay K1 does not enter the positive input ends of the relays K and K2, and the relays K and K2 do not get powered on and pulled on, so that the positive electrode of the 12V power output by the storage battery G can control the power input end and the normally closed contact end through the relay K and perform voltage reduction and current limitation through the resistor R1 to charge the electrolytic capacitor C2, and when the electricity of the electrolytic capacitor C2 is not fully charged within 3 seconds from the beginning, the voltage of the positive electrode of the 12V power entering the silicon controlled rectifier VS control electrode after the positive electrode of the 12V power is subjected to voltage reduction and current limitation through the resistors R1 and R2 is lower than 0.8V, so that the silicon controlled rectifier VS is not. After 3 seconds, when the electrolytic capacitor C2 is fully charged, the voltage of a control voltage which enters the controllable silicon VS after the anode of the 12V power supply is subjected to voltage reduction and current limitation through the resistors R1 and R2 is higher than 0.8V, then the controllable silicon VS is triggered and conducted, and then the cathode of the controllable silicon VS outputs an anode power supply to enter one end of the buzzer B and the resistor R3, the buzzer B is electrified to make a loud prompt sound, the anode of the 12V power supply is subjected to voltage reduction and current limitation through the resistor R3 and enters the anode of the light emitting diode VL, and then the light emitting diode VL (the light emitting surface is positioned outside an opening in the front of the element box) is electrified and emits light, so that each time when an operator turns off the power supply of the salt slurry pump body M, when the power switch S1 is not turned on, the prompt circuit gives. The 3 second time delay is because operating personnel, after closing salt slurry pump body M, operation switch S1 needs certain time, before preventing normal operation switch S1, the sound production of siren B brought unnecessary interference to operating personnel. This is novel to the interior specific time of washing of spiral case, and operating personnel can be as required, select through 3 and 4 foot output power supply time of adjusting time switch A2.

It is shown in fig. 1, 2, through all above-mentioned circuits and mechanism combined action, this novel during operation, at every turn after the user closes the switch of salt stuff pump body M, can self-closing second and fourth solenoid valve case, open first and second solenoid valve case, like this, outside running water can get into the spiral case of salt stuff pump body 1 automatically, wash in the spiral case and impeller etc. and wash, and wash the in-process impeller and can rotate, can reach better washing effect, wash the back waste water and discharge from the waste pipe. In this is novel, the user shuts down at every turn and does not wash salt stuff pump body after a period, and the warning circuit can send warning signal automatically and give the user suggestion, has reduced salt stuff pump body stop work as far as from this, and salt thick liquid is to corruption, the occupy-place of spiral case and internals, has improved salt stuff pump body life and work efficiency as far as possible.
