Tlhaloso ea Sehlahisoa

The motor winding adopts special water-resistant wire for frequency conversion winding, which has excellent characteristics such as high frequency stamping resistance, pulse peak voltage stamping resistance and high temperature aging resistance. The frequency conversion winding design ensures the long-term stable conversion operation of the motor between 1HZ-50HZ, making the frequency conversion deep well pump more energy saving and longer service life.

Maemo a Tšebeliso

The product is supplied by three-phase AC 380V (tolerance ± 5%), 50HZ (tolerance ± 1%). 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 more than 1.5mg/L, chloride ion content is not more than 400mg/L. The motor adopts closed or water-filled wet structure. Before use, the internal chamber needs to be filled with clean water to prevent virtual filling. The pump needs to be completely immersed in water, the penetration depth shall not exceed 70m, and the distance from the bottom of the well shall not be less than 3m. The water inlet of the well shall meet the water output and continuous operation requirements of the pump, and the output of the pump shall be controlled at 0.7-1.2 times of the rated flow. The pump shall be used vertically, and the pump must be matched with the cable according to the requirements and equipped with external overload protection device. It is strictly prohibited to conduct no-load test of the pump, and it is necessary to avoid operation without water.

Litlhokomelo tsa Tšireletso

This well submersible pump is a pump suitable for clean water. It is strictly prohibited to pump sediment and turbid water in new wells. The voltage level of the pump is 380/50HZ. Other voltage levels of the submersible motor need to be customized. Underground cables must be waterproof and must be equipped with starting equipment, such as distribution box, etc. The starting equipment should have common motor comprehensive protection functions, such as short circuit overload protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. Under abnormal circumstances, the protection device should be tripped in time. In the process of installation and use, the pump must be reliably grounded. It is prohibited to push and pull the switch when the hands and feet are wet. The power must be cut off before installation and maintenance of the pump. The place where the pump is used must set up a clear "anti-electric shock" mark. Before going down the well or installation, the motor must be filled with distilled water or non-corrosive cool water, and the water inlet and outlet screws must be tightened. When testing the pump, water must be injected into the pump chamber to lubricate the rubber bearings. The instant start shall not exceed one second to check whether the direction is correct. It is necessary to pay attention to the safety of the pump when it is erected to prevent it from toppling and hurting people. Strictly in accordance with the provisions of the pump lift and flow range of use, so as not to have a large flow in the low lift pump or a large pull in the high lift, causing extreme wear of thrust bearings and other components, resulting in motor overload burn. After the pump into the well, the measurement of the motor and ground insulation resistance, not less than 100M. After the start, regular observation of voltage and current, and check whether the motor winding insulation meets the requirements; if the pump storage location temperature is below freezing, storage should discharge the water in the motor cavity, to prevent the water in the motor cavity due to low temperature and freeze damage the motor.

Likarolo tse kholo tsa sehlahisoa li kenyelletsa:

1.The motor is a water-filled wet submersible three-phase asynchronous motor, the motor cavity is full of clean water, used to cool the motor and lubricate the bearing, the pressure regulating film 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 change of the temperature rise of the motor.

2.In order to prevent the sand in the well water from entering the motor, the upper end of the motor shaft is equipped with two oil seals, and a sand ring is installed to form a sand prevention structure.

3.In order to prevent the pump shaft from running up when starting, the pump shaft and the motor shaft are connected by a coupling, and an upper thrust bearing is installed at the lower part of the motor.

4.The lubrication of the motor and the pump bearing is water lubrication.

5.The motor stator winding is made of high quality submersible motor winding wire, with high insulation performance.

6.The pump is designed by computer CAD, with simple structure and good technical performance.

Tlhokomelo le Tlhokomelo

1.submersible pump installation is complete, re-check the insulation resistance and three-phase conduction from the switch, check the instrument and start the equipment connection error, if there is no problem, can start the trial, after the start of the instrument indicating readings whether more than the nameplate stipulated rated voltage and current, observe the pump noise and vibration phenomenon, everything is normal can be put into operation.

2.pump operation for the first four hours, should be shut down quickly test the thermal insulation resistance of the motor, the value should not be less than 0.5 megaohm.

3.pump shutdown, should be started after an interval of five minutes, to prevent the water column in the pipe has not completely reflux caused by excessive motor current and burnout.

4.pump into normal operation, in order to prolong its service life, to check the supply voltage, working current and insulation resistance is normal, if found the following situation, should immediately shut down troubleshooting.

1.in the rated condition, the current is more than20%.

2.dynamic water level to the water inlet section, causing intermittent water.

3.submersible pump severe vibration or noise.

4.supply voltage is lower than 340 volts.

5.fuse burned out a phase.

6.water pipe damage.

7.motor to the thermal insulation resistance is less than 0.5 megaohm. 5. The product is a pump unit with easy disassembly function, with simple steps of disassembly, so that users can easily maintain and clean. The disassembly steps include unraveling the cable rope, taking down the pipeline part and the line protection plate, unloosening the water discharge bolt, excluding all the water in the motor chamber, removing the filter and loosening the coupling fixing screw fixing the motor shaft, unscrewing the bolt connecting the water inlet section and the motor, separating the pump and the motor (note that the unit should be leveled when separating to prevent the bending of the pump shaft), the disassembly sequence of the pump is: water inlet section, impeller, shunt shell, impeller, and cleaning the valve body. When disassembling the impeller, use special tools to loosen the conical sleeve fixing the impeller. In the whole disassembly process, avoid bending the pump shaft and damaging various parts. The disassembly process of the motor is: put the motor on the platform, and remove the nuts, base, shaft head lock nut, thrust plate, key, and lower guide rail from the bottom of the motor in order. Bearing seat, tie rod bolt, and then take out the rotor (be careful not to damage the wiring harness) and finally remove the connecting section and the upper guide bearing seat. Before assembling the unit, the rust and dirt of each part should be cleaned, and the sealant should be coated on each mating surface and fastener, and then the assembly should be carried out in reverse order according to the disassembly (the movement of the motor shaft after assembly is about 1 mm). After the assembly is completed, the coupling should be flexibly rotated, and then the filter should be put on for machine test. This pump unit is not only convenient and easy to use, but also has detailed instructions, which provides users with convenient maintenance experience. 6. Submersible electric pump every operation for one year, or less than one year but the diving time has reached two years, should be put out of the well according to Article 5 for disassembly and maintenance, and replace the worn parts.
