V, stricte secundum praescripta sentinae tollunt, profluunt usus, ne gravis fluat vel alte elidens vim levare, impulsum ferens et aliae partes induendi, motor oneris combusti 6, post puteum sentinam descendunt; Mensuratio motoris ad terram resistentiae velitae non minus quam 100M esse debet, post initium intentionis et currentis observandi, sisto motore sinuoso insito, sive secundum exigentias; sentinam repono locationis temperaturae si minus quam punctum congelatur, aquae motoris cavitatis aridae esse debet, ne aquae motoris cavitatis glacies per humilitatem damni causata sit.

The pump part is mainly composed of pump shaft, impeller, guide housing, rubber bearing, check valve body (optional) and other components. The motor part mainly includes base, pressure regulating diaphragm, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand discharging ring, water inlet section, lead cable and other components. The main characteristics of this product are that the motor is a water-immersed three-phase asynchronous motor, and the motor cavity is filled with water to cool the motor and lubricate the bearing. The pressure regulating film at the bottom is used to adjust the pressure difference of the water body in the cavity caused by the temperature rise of the motor. In order to prevent the sand from entering the motor, the upper end of the motor shaft extension is equipped with two oil seals and installed a sand discharging ring, forming a sand prevention structure. At the same time, in order to prevent the pump shaft from jumping when starting, the pump shaft is connected with the motor shaft by a coupling, and the thrust bearing is installed under the motor. The lubrication of the whole product is water lubrication, and the motor stator winding is made of high quality submersible motor winding wire with high insulation performance. In addition, the pump is designed by computer CAD, with simple structure and excellent technical performance.

7. Cable joint, cut off a 120mm rubber sleeve from one end of the outgoing cable and the matching cable with an electrician's knifethen stagger the length of the three core wires in a stepped shape, peel off a 20mm copper core, scrape of the oxide layer on theoutside of the copper wire with a knife or sand cloth, and insert the two connected wire ends in palirs.After tying the layer tightly with fine copper wire, solder it thoroughly and firmly, and sand of any. burrs on the surface. Then, forthe three joints, use polyvester insulation tape to wrap them in a semi stacked manner for three lavers. Wrap the two ends of thewrapping layer tightywith nyion thread,and then use a semi stacked method to wrap the tape for three layers. Wrap the outellayer with high-pressure insulation tape for three layers. Finally, fold the threestrands together and repeatedly wrap them for fivelayers with high-pressure tape. Each layer must be tightly tied, and the interlayer joints must be tight and fimm to prevent water frompenetrating and damaging the insulation, After wrapping, soak in water at room temperature of 20 ’c for 12 hours, and measurethe insulation resistance with a shaking table, which should not be less than 100M Ω

Eadem methodo omnes aquae fistulas in puteum alligant.
⑤Post funem plumbeum ad imperium transitum coniungitur, cum copia trium phase iungitur.

(4.) Notae in installation:
1. Si vallum phaenomenon in flantibus processum inveniatur, vertere vel fistulam aquam trahere, ut punctum vallum superetur. Si variae mensurae adhuc non operantur, quaeso Noli sentinam cogere ad vitandum damnum in sentinam electricam et puteum submersibilem.
2. In institutione, codex iuvantis ad cuiusque fistulae LABIUM collocari debet et aequaliter coarctari.
3. Cum aqua sentina in puteum demissa, in media fistula putei poni debet, ne sentinam contra murum putei diu curreret, sentinam pulsum et motorem verrere et comburere. .

7. Cum aqua currit sentina, aqua output continuum et par esse debet, currens sit stabilis (sub condiciones operationis aestimatae, plerumque non plus quam 10% currentis aestimatae), nec vibratio nec strepitus esse debet. Si qua deprauatio est, machina cessari debet causam cognoscendi et removendi.
8. Cum inaugurari, attende ad occasum filum fundationis motoris (vide Figure 2). Fistula cum aqua est ferrea tibia, a puteo fibulato duc; cum fistula aquatica fistula plastica est, eam a fundamento sentinae electrici notam duc.

The use of underwater pumps need to be carried out in strict accordance with the following steps: First of all, after the installation of the underwater pump, it is necessary to recheck the insulation resistance and the three-phase continuity of the switch, and check whether there are errors in the connection of the instrument and the start equipment. If there is no problem, you can start to test the machine. After the start, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has any noise or vibration. If everything is normal, it can be put into operation. The second step, after the pump runs for four hours for the first time, it should be closed and the thermal insulation resistance of the motor should be tested quickly. Its value should not be less than 0.5 megaohm. The third step, after the pump stops, it should be restarted after five minutes to prevent the water column in the pipeline from completely reversing, resulting in the motor burning due to excessive current. The fourth step, after the pump is put into normal operation, in order to prolong its service life, it is necessary to check the power supply voltage, operating current and insulation resistance regularly to see if they are normal. If the following conditions are found, the machine should be shut down immediately to troubleshoot:

1 the current exceeds 20% under the rated working conditions.

2 the dynamic water level drops to the inlet section, causing intermittent drainage.

3 the underwater pump vibrates violently or makes a lot of noise.

4 the supply voltage is lower than 340 volts.

5 a fuse burned. 6 water pipe damage.

7 the motor to the ground thermal insulation resistance is less than 0.5 megaohms.

The fifth step, the removal of the unit:

1 untie the cable tether, remove the pipe part, and remove the line protection plate.

2 screw down the water bolt and discharge all the water in the motor chamber.

3 remove the filter and loosen the fixing screw on the coupling fixed motor shaft.

4 screw down the bolt connecting the water inlet section and the motor, separate the pump and the motor (pay attention to make the unit level to prevent the bending of the pump shaft when separating)

5 the removal sequence of the pump is: (see Figure 1) water inlet section, impeller, shunt shell, impeller, check valve body. When removing the impeller, use special tools to loosen the cone sleeve fixed the impeller. In the process of removal, avoid bending the pump shaft and damage the various parts.

6 the removal process of the motor is: (see Figure 1) put the motor on the platform, and in order from the bottom of the motor bolt nuts, base, shaft head lock nut, thrust plate, key and lower guide bearing seat (iron rod bolt) on the connecting parts, and then take out the stator (careful not to damage the wire packet), and finally remove the connecting part and the upper guide bearing seat. Unit assembly: before assembly, rust and dirt on each component should be cleaned and sealant should be applied to each mating surface and fastener, and then the assembly should be carried out in reverse order of disassembly (the motor shaft moves about 1 mm after assembly), the coupling should be flexible after assembly, and then the filter should be put on for testing. Step six, after each use of the underwater electric pump operation for one year, or less than one year but immersed for two years, the disassembly and inspection should be carried out in accordance with the provisions of Article 5 to replace the worn parts.
