300QJP Peep Daradara Submersible fifa

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, ni ibamu si awọn ipese ti fifa fifa soke, iwọn lilo ti sisan, lati ṣe idiwọ sisan kekere tabi agbara fifa soke, gbigbe gbigbe ati awọn ẹya miiran ti yiya, apọju motor sun.

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.
