(Ⅱ) Equipment and Tools Installation

1. one set of hoist chain of a weight of over 2 tons, one tripod with aof no less than 4 meters, or any other hoistequipment
2. lifting ropes (steel wire) with endurance of over one tons weight(the weight of awhole set of water pump)
3. sets of lathe dog (clamp plate) installation
4. Spanner, hammer, screw driver, electric tools and other instruments etc

(Ⅲ) Installation of Water Pump:

1. submersible electric pump with pump increase of less than 30 meters can utilizeose, directly use steel wire or other rope with weight endurance of the whole machineand water pipe as well as all water in the pipe for hoist installation in the well.
2. apply steel pipe for pump with pump increase over 30 meters with the followingstall ation order:
(1) Use lathe dog to clamp the upper part of water pump, with electric motor and watepump connected, hoist it up and slowly drop into the water until the lathe dog hangson the well entrance and release the hoist chain.
(2) Clamp a pipe using another set of lathe dog, and hoist it using hoist chadistance of 15 cm to flange and slowly drop it down. Make sure cushions have beenplaced in pipe flange and pump flange, use bolts and nuts and spring cushions toevenly tighten the pipe and pump.
(3) Hoist the submersible pump slightly, take off the lathe dog on the upper side of thewater pump, and use plastic band to tighten cables to water pipes, and slowly dropdown to make the lathe dog hang on the well entrance.
(4) Apply the same method to deliver all water pipes into the well.
(5) After bringing out the cable and connecting the control switch, connect the 3 phasepower supply. (refer to the attached table in page 20 on submersible electric pumpsupplemental switch, cable parameters)

(Ⅳ)Caution during Installation:

1.Once locking occurs when dropping down the pump, switch or turn the water pipeand overcome the locking point, if various measures are still not effective, it is stricforbidden to force ably drop down the pump, so as to avoid submersible electric pumpocking up with the well or being damaged.
2. During installation, cushions should be placed at flange on each pipe, andevenly apply force to tighten.
3. According to conditions of drift sand and sludge in the water well, make sure thepump has reached a certain depth to the bottom of the well, it is forbidden tobury pump into sludge, the distance between well bottom and the pump isnormally keptno less than 3 meters(see fig. 2).
4. For the pumps water depth, the gap between dynamic water level and wateentry point is no lesan5 meters(see figure 2), otherwise, the watepump bearing could be easily damaged.
5. The pumps lift could not be too low, otherwater pipe at the well entrance to control pumps water flow at a rated flow point, to as to avoid motor overload and burning resulted from exceeding volume ofwater flow.
6. During pump operation, water drainage should be evenly and consistentelectric current should be steady (no more than 10% of the rated current), novibration and noise. If malfunctions occur, problems should be found and solvedn a timely fashion.
7. During installation, be aware of the setup of earth wire for the electric motor (see fia. 2), if water pipe is steel pipe, lead wire from the lathe dog at the welentrance; when the water pipe is plastic, lead wire from the screw at water pump's dust gauze.

6.Usage and Maintenance

1. After finishing the installation of submersible electric pump, check continuitysituation of the insulation resistance and three-phase again at the position of switchCheck if there is any error in the connection of instrument and starting equipment. Startd try the machine only if there is any problem. After starting, observe if the indicatinreadings of every instrument surpass the rated pressure and current described on thenameplate. Listen to make sure if there is any noise or libration phenomenon existing inthe pump Start operation if everything is normal.
2. After the first four-hour running of pump, stop the machine and test the insulationresistance of heat-stated motor rapidly with a value of =0.5MΩ
3. Restart the pump with a 5 minutes interval after the stop of pump to prevent highcurrent when start the motor and leading to burning caused by incompletecircumfluence of the water in the water-feeding pipe.
4. After the normal operation of pump, do periodical check on the power supplypressure, working current and insulation resistance to prolong its life time. If thefollowing situations are found, stop the pump and eliminate the faults instantly.
1) Under the rated working conditions, current exceeds 20%.
2）The moving water level decreases to water-in structure causing interval water out.
3) The submersible pump shakes violently or has a loud noise.
4) The power supply pressure is lower than 340V.
5) One-phase of fuse is burnt out.
6)The water transmission pipe is damaged.
7) The heat state insulation resistance of motor to ground is lower than 0.5 MΩ
5. Disassembly of Machine
1) Unfasten the tied rope ofthe electric cable, take down the pipeline part and wireprotection plate.
2) Screw down the water-discharging bolt to emit out the water in the motor cavity.
3) Take down the filter wire mesh and unfasten the fixing screw of the fixing motoraxis in the coupling.
4) Screw down the bolt connecting the water-in structure and motor. Divide thepump from motor (Notice that one should fill up the machine flat to avoidbending of pump axis during the division).
5) The disassembly order of water pump is: (Figure 1) water-in structeading shell, impeller.check valve. At the time of knock down the impeller,use special tool to loose the subulate slipcover of fixing impeller. And avoidbending of pump axis and damage of every part during the knock down process.
6) The disassembly process of motor is: (Figure 2) Put the motor on the platforand knocks down the nut of dual head bolt, pedestal, tight nut at the shaft endthrust disc, button, down leading bearing base, dual head bolt from the bottomof motor in turn.
