200QJ Va'a Lo'o Fa'a'ele'ele Pamu

QJ series submersible pump is a kind of water lifting machine directly connected to the submersible motor and pump to work in the water. This series of pumps is vertical, small use area, compact structure, easy installation, easy maintenance and repair. Widely used in agricultural irrigation, municipal engineering, water conservancy engineering, urban water supply and drainage and industrial and mining enterprises, drought relief and flood drainage and other fields. Flow range of 5-500m3/h, lift of 4-800m, power 3-315KW. The QJ series submersible pump has stable and reliable performance, suitable for various needs of pump applications.

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

1. （1）After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon. If everything is normal, it can be put into operation.
2. （2） After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
3. （3） After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing the motor to burn out due to excessive current.
4. （4）After the pump is put into normal operation, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, running current and insulation resistance are normal.If the following conditions are found, the pump should be shut down immediately to eliminate the fault:
5. 1 under the rated working conditions, the current exceeds 20%;
6. 2 the dynamic water level drops to the water inlet part, resulting in intermittent drainage;
7. 3 the submersible pump vibrates seriously or emits huge noise;
8. 4 the supply voltage is lower than 340 volts;
9. 5 a fuse is blown out;
10. 6 the water pipe is damaged;
11. 7 the thermal insulation resistance between the motor and the ground is less than 0.5 megaohm. The discovery of these problems need to be handled in time to ensure the normal operation of the pump, improve its reliability, so as to ensure the stable operation of the equipment for a long time.

（5）unit disassembly:

 1 untie the cable tie, remove the pipeline part, remove the wire plate.

 2 vili i lalo le fa'amau vai, tu'u le vai i totonu o le potu afi.

 3 remove the filter, loose the fixing screw on the coupling to fix the motor shaft.

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

 5 pump disassembly sequence is: (see figure 1) water inlet section, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, avoid bending the pump shaft and each part in the disassembly process.

 6 motor disassembly process is: (see figure 1) place the motor on the platform, and remove the nut, base, shaft head lock nut, thrust plate, key, lower guide bearing seat, double head bolt from the bottom of the motor in turn. Then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and the upper guide bearing seat.

 7 unit assembly: Before assembly, the rust and dirt of the parts should be cleaned, and the mating surfaces and fasteners should be coated with sealant. Then they should be assembled in the reverse order of disassembly (the up and down momentum of the motor shaft is about 1 mm after assembly). After assembly, the coupling should be flexible, and then the filter screen test machine.

6. The submersible pump should be dismantled and repaired according to Article 5 for each operation year, or less than one year, but the submersible time has reached two years, and the worn parts should be replaced.

 1, tuu i fafo le vai i totonu o le afi (aemaise lava i le taumalulu e puipuia ai le afi mai le malulu), ma nonoa lelei le uaea.

 2, store in an indoor room without corrosive substances and gases, with a temperature below 40 °C.

 3, faʻaaogaina umi e tatau ona gauai atu i le puipuia o le ele o pamu submersible.
