The product adopts special water-resistant wire for motor winding, with excellent characteristics such as high frequency shock resistance, pulse peak voltage shock resistance and high temperature aging resistance. The frequency conversion winding design ensures the motor to operate smoothly between 1Hz and 50Hz for a long time, making the frequency conversion deep well pump more energy saving and longer service life.

We are honored to introduce our products, this product provides three-phase AC 380V power supply (tolerance of ± 5%), 50HZ voltage (tolerance of ± 1%). At the same time, our products require strict water quality requirements: water temperature is not higher than 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 adopts closed or water-filled wet structure, which must be filled with clean water before use to prevent empty. Tighten the water charging and deflating bolts before use, otherwise, it is not allowed to use. The submersible pump must be completely immersed in water to work, the immersion depth shall not exceed 70 meters, and the distance between the bottom of the submersible pump and the bottom of the well shall not be less than 3 meters. The well water flow shall meet the output and continuous operation requirements of the submersible pump, and the output of the submersible pump shall be controlled at 0.7-1.2 times of the rated flow. The well must be vertical, and the submersible pump can not be used horizontally or inverted, but only vertically. The submersible pump must be equipped with cables according to requirements, and is equipped with external overload protection devices. It is strictly prohibited to conduct no-load tests on the pump without water. Our products guarantee to provide you with high quality and stable performance, while meeting your needs to ensure safe and reliable.

This well submersible pump is a pump suitable for clean water. Digging new wells and pumping sediment and turbid water are strictly prohibited. The voltage grade of the well pump is 380V/50HZ. Submersible motors with other voltage grades need to be customized. Underground cables must use waterproof cables and must be equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have common comprehensive motor protection functions, such as overload short circuit protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. In abnormal cases, the protection device should be tripped in time. During installation and use, the pump must be reliably grounded. It is prohibited to push and pull the switch when hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. The place where the pump is used must be set up with obvious "anti-electric shock" marks. Before going down the well or installation, the motor must be injected with distilled water or non-corrosive clear cold water in the inner cavity, and the intake/drain bolts must be tightened. When testing the pump on the ground, water must be injected into the pump chamber to lubricate the rubber bearings. The instant start time should not exceed one second to check whether the direction is correct. The same as the steering instructions. Pay attention to safety when the pump is upright to prevent tilting and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump flow at low lift or in high lift pull too large, resulting in extreme wear of thrust bearings and other components, the motor due to overload and burn. After put into the well, the measurement of the motor and the ground insulation resistance value, not less than 100M. After the start, regular observation of voltage and current, and check the motor winding insulation is in line with the requirements of the provisions. If the temperature of the storage site is below the freezing point, the water in the pump chamber should be drained to prevent the water in the motor chamber from freezing and damaging the motor due to low temperature.

• 1.After installing the submersible pump, recheck the insulation resistance and three-phase continuity switch, check whether there is any error in the connection between the instrument and the starting equipment.If there is no problem, you can start to test the machine. After starting, observe whether the indication reading of each instrument is correct.If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has noise or vibration.If everything is normal, it can be put into operation. After the pump runs for the first time for four hours, the motor thermal insulation resistance 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 five minutes to prevent the water column in the pipeline from completely reversing, which will cause the motor to burn out due to excessive current.
•  
• 2.After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the machine should be stopped immediately to troubleshoot.
• 1.Under the rated working condition, the current exceeds 20%.
• 2.The dynamic water level drops to the water inlet section, resulting in intermittent water.
• 3.The submersible pump has severe vibration or noise.
• 4.The supply voltage is lower than 340 volts.
• 5.A fuse is burned out.
• 6.The water pipeline is damaged.
• 7.The motor's insulation resistance to the geothermal state is lower than 0.5 megaohm.
•  
• 3.Unit disassembly:
• - Copot dasi kabel, copot bagean pipa, lan copot piring kabel.
• - screw down the water bolt, put out the water in the motor chamber.
• - mbusak Filter, ngeculke meneng tetep ing kopling kanggo mbenakake poros motor.
•  
• 4.screw down the bolt connecting the water inlet section 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) 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, and avoid bending and bruising 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 opposite 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.

 1, sijine metu banyu ing growong motor (utamané ing mangsa kanggo nyegah motor saka pembekuan), lan dasi kabel uga.

 2, simpen ing kamar njero ruangan tanpa zat korosif lan gas, kanthi suhu ing ngisor 40 °C.

 3, nggunakake long-term kudu mbayar manungsa waé kanggo Nyegah teyeng saka pumps submersible.
