175QJP Peep Well Submersible Pump

QJP series fountain pump is a special pump for fountain developed by our factory.The pump motor core is made of high quality cold rolled silicon steel, which makes the pump more efficient, good magnetic conductivity, and frequent start will not fever.Both ends of the motor rotor use water as lubricant alloy copper sleeve.Stainless steel sleeve instead of ball bearings, to avoid the problem of easy rust ball bearings and lack of oil wear and tear the motor.The most suitable for music fountain use, all models can be used.

This product is a three-phase AC 380V (tolerance + / - 5%), 50HZ (tolerance + / - 1%) power supply system. Applicable water quality conditions include water temperature not exceeding 20 °C, solid impurities content (mass ratio) is not greater than 0.01%, PH value (pH) is 6.5-8.5, hydrogen sulfide content is not greater than 1.5mg/L, chloride ion content is not greater than 400mg/L. The motor is a closed or water-filled wet structure. Before use, it must be filled with clean water to prevent false filling, and then tighten the water injection and exhaust bolts, otherwise it is not allowed to use. The submersible pump must be completely immersed in water, and the penetration depth shall not exceed 70m. The distance between the submersible pump base and the bottom of the well shall not be less than 3m. The well flow shall be able to meet the water output and continuous operation of the submersible pump. The water output of the submersible pump shall be controlled at 0.7-1.2 times of the rated flow. The well shall be vertical, and the submersible pump can not be used horizontally or upside down, but only vertically. The submersible pump shall be equipped with cables and external overload protection devices as required. The pump is strictly prohibited from no-load test without water.

1, well submersible pump for clean water pump, prohibit the new well, pumping sediment and muddy water,

2, well water pump voltage grade of 380/50HZ, the use of other voltage grades of submersible motors need to be customized. The underground cable must use waterproof cable, must be equipped with starting equipment, such as distribution box, start not ready should have commonly used motor comprehensive protection function, such as short circuit overload protection, phase protection, undervoltage protection, grounding protection, idling protection, in case of abnormal conditions, the protection device should be timely action trip.

3, the installation and use of the pump must be reliably grounded, prohibit the push and pull switch when the hands and feet are wet, the installation and maintenance of the pump must be cut off the power supply, the use of the pump place to set up "to prevent electric shock" obvious signs:

4, down the well or before installation, the motor cavity must be filled with distilled water or non-corrosive clean cold boiling water, tighten the / water bolt, the pump on the ground test run, must be to the pump chamber water lubrication rubber bearings, instant start not more than a second, see whether the steering is the same as the steering instructions. When the pump is upright, pay attention to safety, prevent overturning injury.

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.After installing the submersible pump, recheck the insulation resistance and the three-phase continuity at the switch, and check whether there are errors in the connection of the instrument and the starting equipment.If there are no problems, you can start to test the machine. After starting, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, observe whether the pump emits any noise or vibration. If everything is normal, it can be put into operation.
• 2. After the pump runs for the first four hours, the thermal insulation resistance of the motor should be closed and tested quickly.Its value should not be less than 0.5 megaohm.After the pump stops, it should be restarted after an interval of five minutes to prevent the water column in the pipeline from completely reversing and burning the motor due to excessive current.
• 3. 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, working current and insulation resistance are normal. If the following conditions are found, the machine should be stopped immediately to troubleshoot.

• Unit disassembly:
• 1.untie cable rope, remove the pipeline part, remove the wire plate.
• 2.screw down the water bolt, put the water in the motor chamber.
• 3.remove the filter, loose the fixed screw on the coupling to fix the motor shaft.
• 4.screw down the bolt connecting the inlet junction with the motor, and separate the pump from the motor (pay attention to the unit cushion when separating, to prevent the bending of the pump shaft)
• 5.the disassembly sequence of the pump is: (see figure 1) inlet junction, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, and avoid bending and bruising of the pump shaft in the process of disassembly.
• 6.the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nuts, base, shaft head locking nut, thrust plate, key, lower guide bearing seat and double head bolt from the bottom of the motor in turn, and then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
• 7.unit assembly: before assembly, the rust and dirt of the parts should be cleaned, and the mating surface and fasteners coated with sealant, and then assembled in the reverse order of disassembly (the motor shaft moves up and down after assembly for about one millimeter), after assembly, the coupling should be flexible, and then the filter screen test machine. Submersible pumps shall be taken out of the well for dismantling and maintenance according to Article 5 after a year of operation, or less than a year of operation but two years of diving time, and the worn parts shall be replaced.

This product adopts advanced design and provides advanced storage suggestions to ensure long-term use effect.First of all, in winter, it is necessary to exhaust all the water to prevent freezing. In addition, the wire rolls should be placed well and tied up.Secondly, when storing, the environment without corrosive action and gas should be selected and the temperature should be kept below 40 °C. Finally, when not used for a long time, attention should be paid to prevent rust of submersible pump.These storage requirements will ensure that the product can maintain its performance status and prolong its service life for a long time.
