QJ series submersible pump is a kind of water lifting equipment directly connected to the submersible motor and pump to work in the water. This series of pumps are vertical, with small use area, compact structure, simple installation, convenient maintenance and repair. It is widely used in agricultural irrigation, municipal engineering, water conservancy engineering, urban water supply and drainage, industrial and mining enterprises water supply and drainage, drought relief and flood relief and so on. The flow range is 5-500m3/h, the head is 4-800m, and the power is 3-315KW. This product has stable and reliable performance, can meet the needs of various different uses of pumps, and is one of the excellent choices in the market.

This product is a three-phase AC 380V electric pump, suitable for various pump applications. The power supply requirements for ± 5% of the three-phase AC 380V voltage, 50HZ frequency fluctuation range of ± 1%. Water quality requirements include water temperature not higher than 20 °C, solid impurities content (mass ratio) is not greater than 0.01%, PH value of 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 a closed or water injection wet structure, before use must be submersible motor inner cavity filled with clean water to prevent empty, while fastening the water injection and pressure relief bolts, otherwise not to use. Submersible pump must be completely immersed in water work, immersion depth shall not exceed 70 meters, the distance from the bottom of the pump to the bottom of the well shall not be less than 3 meters. Well water inflow shall meet the water output and continuous operation requirements of submersible pump, pump output shall be controlled at 0.7-1.2 times the rated flow. The well must be vertical, submersible pump can not be used horizontally or tilted, only vertical use. Submersible pump must be equipped with cables as required, and equipped with external overload protection device. It is strictly prohibited to do no-load test without 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 common 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 pump must be reliably grounded in the process of installation and use. Prohibit push and pull switch in the case of wet hands and feet. Must cut off the power supply before installation and maintenance of electric pumps. Must install "electric shock prevention" obvious mark in the place where the pump is used. Before going down the well or installation, the motor cavity must be filled with distilled water or non-corrosive clean cold water, and must tighten the water inlet / outlet bolts.

4, when the pump is tested on the ground, water must be added to the pump cavity to lubricate the rubber bearing. The instantaneous start can not exceed one second, check whether the direction is the same as the direction indicated. When the pump is placed vertically, pay attention to safety to prevent overturning and injury.

(5)This product is a portable water pump, with the characteristics of easy disassembly, the user can disassemble and clean the various components according to the following steps to maintain the normal operation of the pump. First of all to untie the cable tie, remove the pipeline part and take off the line protection plate. Then unscrew the drain bolt, discharge all the water in the motor chamber. Then take off the filter, loosen the fixing screw on the coupling fixed motor shaft. Then unscrew the bolt connecting the water inlet section and the motor, the pump and the motor separation (pay attention to the device leveling when separating, to prevent the bending of the pump shaft). The sequence of disassembly of the pump is: water inlet section, impeller, guide housing, impeller, check valve body. When disassembling the impeller, use special tools to loosen the cone sleeve fixed the impeller. In the whole disassembly process, pay attention to avoid bending the pump shaft and damage various parts. The steps of motor disassembly are: put the motor on the platform, remove the nut, seat, shaft head lock nut, thrust plate, key, lower guide rail from the bottom in order (tie rod bolt), then remove the rotor (pay attention not to damage the wire packet), and finally remove the connecting section and the upper guide bearing seat. Before assembly, the rust and dirt of each part should be cleaned, and sealant should be applied to each mating surface and fastener, and then the assembly should be carried out in the opposite order of disassembly (the movement of the motor shaft after assembly is about 1 mm). After assembly, the coupling should be flexible, and then the filter should be put on for machine test. 6. Submersible electric pump should be taken out of the well for dismantling and maintenance according to Article 5 after operating for one year, or less than one year, but the diving time has reached two years, and the worn parts should be replaced.
