1. when the device is used, the number of the impellers in the deep-well pump can be increased or reduced according to the requirements of the used well depth, when a second impeller is required to be increased, only the locking screw needs to be disassembled, then the second shell is separated from the third shell, then the required number of the second shell and the second impeller need to be increased at will, when the device is added, the clamping block is aligned to the clamping groove to be clamped, the second rotating shaft and the transmission shaft can be automatically in transmission connection, and then the second rotating shaft and the transmission shaft are fixed through the locking screw, the whole adding process is convenient and rapid, and the number of the first impeller and the second impeller can reach the required number;
2. according to the invention, when water flows enter the interior of the extension pipe, the flow rate of the water flow can be monitored in real time through the flow rate monitoring device, if the flow rate of the water flow can meet the target requirement, the first electromagnetic valve is opened, the second electromagnetic valve and the third electromagnetic valve are closed, and the third impeller does not need to rotate, so that unnecessary energy waste can be reduced;
3. according to the invention, large-particle impurities are prevented from contacting with the first impeller and the second impeller through the water inlet through the filter screen, so that the service life of the device can be prolonged, a large amount of impurities can be clamped on the surface of the filter screen along with long-time use of the device, the water inflow of the device is easily influenced, so that when the device is stopped to use, the pump body can be opened, so that high-speed water flow is sprayed out from the spray head, then the impurities clamped on the surface of the filter screen are washed away in a reverse direction through the high-speed water flow, and the subsequent use effect of the device can be improved.
4. When the deep well liquid level control device is used, if the liquid level in the deep well is lowered, the position of the floating ball is lowered, and the pressure switch can control the first motor to be turned off until the pressing block is contacted with the pressure switch due to the lowering of the position of the floating ball, so that the first motor and the impeller are effectively prevented from idling and generating inconvenient waste due to the fact that the liquid level in the deep well is low.

the first step is as follows: when the device is used, the first impeller 5 is driven to rotate by the first motor 7, so that water can be thrown to the obliquely upper part by the first impeller 5, a vacuum area is formed in the middle of the first impeller 5, so that external water can continuously flow into the first impeller 5 through the water inlet 2 and then be thrown out under the action of centrifugal force, the water pumping effect can be achieved by reciprocating, the second impeller 14 can be driven to rotate by the fixture block 16 and the clamp groove 15 while the first impeller 5 rotates, so that after the water flow is accelerated once by the first impeller 5, the water flow can be pressurized and accelerated again by the second impeller 14, the water pumping effect of the device can be improved, in addition, the number of the impellers in the deep well pump can be increased or reduced according to the used well depth, when the second impeller 14 needs to be increased, only the locking screw 21 needs to be disassembled, then the second shell 3 is separated from the third shell 12, then the second shell 3 and the second impeller 14 with required quantity are added at will, when adding, the clamping block 16 is aligned with the clamping groove 15 and clamped, so that the second rotating shaft 13 and the transmission shaft 8 can be automatically in transmission connection, and then the whole adding process is convenient and quick, so that the quantity of the first impeller 5 and the second impeller 14 can reach the required quantity;
the second step is that: the water flow pumped by the first impeller 5 and the second impeller 14 of the device can enter the extension pipe 24 through the discharge pipe 23, and the water flow can monitor the flow rate of the water flow at the moment in real time through the flow rate monitoring device 26 when entering the extension pipe 24, if the flow rate of the water flow can reach the target requirement at the moment, the first electromagnetic valve 27 is opened, the second electromagnetic valve 28 and the third electromagnetic valve 36 are closed, the third impeller 32 does not need to rotate, thereby reducing unnecessary energy waste, if the flow rate of the water flow can not reach the target requirement at the moment, the first electromagnetic valve 27 can be controlled to be closed, the second electromagnetic valve 28 and the third electromagnetic valve 36 are controlled to be opened, then the water flow can flow into the cavity 30, at the moment, the second motor 34 is opened, so that the second motor 34 rotates, and the second motor 34 can drive the third impeller 32 to rotate when rotating, thereby repressurizing the water flow in the cavity 30 through centrifugal force, so that the water flow reaches the target pressure and can be pumped to the target height;
the third step: when the device is used, large-particle impurities can be prevented from contacting with the first impeller 5 and the second impeller 14 through the water inlet 2 through the filter screen 50, so that the service life of the device can be prolonged, a large amount of impurities can be clamped on the surface of the filter screen 50 along with long-time use of the device, the water inflow of the device is easily influenced, so that when the device is stopped to be used, the pump body 51 can be opened, high-speed water flow is sprayed out of the spray head 48, then the impurities clamped on the surface of the filter screen 50 are washed away in a reverse direction through the high-speed water flow, and the subsequent use effect of the device can be improved;
the fourth step: if the liquid level in the deep well is reduced when the device is used, the position of the floating ball 45 can be reduced until the position of the floating ball 45 is reduced to enable the extrusion block 46 to be in contact with the pressure switch 44, and then the pressure switch 44 can control the first motor 7 to be closed, so that the situation that the liquid level in the deep well is low, the first motor 7 and the impeller are idle, and inconvenient waste is generated can be effectively prevented.
