300QJP Peep Well Submersible Pump

QJP series special fountain pump is a special fountain pump developed by our factory. The pump motor core is made of high quality cold rolled silicon steel, which makes the pump more efficient, has good magnetic conductivity, and does not produce heat when starting frequently. The two ends of the motor rotor are covered with alloy copper sleeves as lubricant. Stainless steel sleeves replace ball bearings, avoiding the problem of easy rust of ball bearings and burnout caused by motor lack of oil wear. Most suitable for music fountains, all models can be used flat.

The product is powered by three-phase AC 380V power supply, 50HZ pump, suitable for water temperature is not higher than 20 °C, solid impurities content is not greater than 0.01%, PH value between 6.5-8.5, hydrogen sulfide content is not greater than 1.5mg/L, chloride ion content is not greater than 400mg/L water quality conditions. The product adopts closed or water-filled wet structure of the motor, before use the submersible motor chamber filled with clean water to prevent the occurrence of virtual filling. The submersible pump must be completely immersed in water operation, penetration depth shall not exceed 70 meters, to the bottom of the well distance shall not be less than 3 meters. The water flow in the well must meet the water requirements of the submersible pump and continuous operation, and the water output of the pump is controlled between 0.7-1.2 times the rated flow. The well should be vertical and the submersible pump can only be placed vertically, not horizontal or upside down. The submersible pump must be equipped with cables and external overload protection devices as required. It is strictly prohibited to conduct no-load test of the pump 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.

5, nruj me ntsis raws li cov kev cai ntawm lub twj tso kua mis nqa, ntws ntau yam ntawm kev siv, los tiv thaiv qis ntws los yog siab nqa twj tso kua mis quab yuam, lub thrust bearing thiab lwm yam ntawm hnav, lub cev muaj zog overload hlawv.

6, after the pump down the well, the measurement of the motor to the ground insulation resistance should not be less than 100MΩ, after the start to observe the voltage and current, check the motor winding insulation, whether it meets the requirements; pump storage location temperature if less than freezing point, should be dry the motor cavity water, prevent the motor cavity water ice damage caused by low temperature motor

The pump parts of this product are mainly composed of pump shaft, impeller, shunt shell, 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 ring, water inlet section, lead cable and other components. The product adopts water immersion wet three-phase asynchronous motor, the motor cavity is full of clean water, used to cool the motor and lubricate the bearing. The pressure regulating diaphragm set at the bottom of the motor is used to adjust the expansion and contraction pressure difference of the water inside the body caused by the temperature rise of the motor. In order to prevent the sand particles from entering the motor, the upper end of the motor shaft extension is installed with two oil seals, and the sand ring is set to form a sand blocking 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 through the coupling, and the bottom of the motor is equipped with a thrust bearing. The motor and pump bearing are lubricated by water. The stator winding of the motor adopts high quality submersible motor winding with high insulation performance. The pump design adopts computer CAD, with simple structure and good technical performance.

(1) Kev npaj ua ntej installation:
1. Xyuas seb lub twj tso kua mis submersible puas ua tau raws li qhov kev siv thiab qhov tshwj xeeb hauv phau ntawv qhia.

6. Unscrew cov dej ntsia hlau thiab sau cov kab noj hniav nrog cov dej huv, tsis muaj corrosive (ceeb toom. Nco ntsoov sau nws), tom qab ntawd ceev cov dej screws. Tom qab 12 teev ntawm kev txhaj tshuaj dej, qhov rwb thaiv tsev ntawm lub cev muaj zog yuav tsum tsis txhob tsawg dua 150M Q thaum ntsuas nrog 500V co lub rooj.
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

Daim duab txuas cable thaiv txheej txheem yog raws li hauv qab no:

8. Siv multimeter los xyuas seb cov xov hlau peb-theem puas txuas thiab seb qhov DC tsis kam yog kwv yees li qhov sib npaug.
9. Xyuas seb puas muaj peev xwm ntawm lub Circuit Court thiab transformer yog overloaded, thiab ces txuas lub overload tiv thaiv hloov los yog pib cov khoom. Saib Table 2 rau cov qauv tshwj xeeb, thiab tom qab ntawd hliv ib lub thoob dej rau hauv lub twj tso kua mis los ntawm lub qhov dej twj tso kua mis kom lubricate cov roj hmab bearings hauv lub twj tso kua mis, thiab tom qab ntawd muab lub twj tso kua mis submersible fais fab tso ncaj thiab khov kho.Start (tsis pub ntau tshaj ib ob) thiab xyuas seb qhov kev taw qhia lub kauj tsheb puas zoo ib yam nrog lub kauj tsheb. Yog tias tsis yog, sib pauv ob qhov txuas ntawm peb-theem cable.Tom qab ntawd nruab lub lim thiab npaj mus rau hauv qhov dej. Yog tias siv rau lub sijhawm tshwj xeeb (xws li kwj dej, kwj dej, dej ntws, pas dej, pas dej, thiab lwm yam), lub twj tso kua mis hluav taws xob yuav tsum muaj kev ntseeg siab.
