135QJP Peep Well Submersible Pump

Introducing the innovative QJP series fountain pump, a product of superior efficiency meticulously developed and researched by our factory. With a meticulously designed pump motor core crafted from premium cold rolled silicon steel, this fountain pump boasts exceptional magnetic conductivity, enabling seamless and heat-free starts. Unlike traditional fountain pumps, the 0JP series features motor rotor ends that utilize a unique water-lubricated alloy copper sleeve, replacing standard ball bearings. This innovative design not only mitigates issues of rust and wear caused by lack of oil but also ensures longevity and durability for the motor. Upgrade your fountain experience with the cutting-edge technology and superior performance of the QJP series fountain pump.

The product is a three-phase AC 380V (tolerance + / - 5%), 50HZ (tolerance + / - 1%) power supply, and has strict requirements for clean water: water temperature shall not exceed 20 °C; solid impurities content (mass ratio) shall not exceed 0.01%; PH value (pH) is 6.5-8.5; hydrogen sulfide content shall not exceed 1.5mg/L; chloride ion content shall not exceed 400mg/L. The product adopts a closed or water immersion structure motor, the submersible motor must be filled with clean water before use to prevent empty. In addition, the water can be used after filling and tightening the air release bolt. The submersible pump must be completely immersed in water to work, the diving depth shall not exceed 70m, and the distance between the bottom of the pump and the bottom of the well shall not be less than 3m. The well water flow should meet the water output and continuous operation requirements of the submersible pump, and the water output 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, and it must be installed vertically. The submersible pump must match the cable as required and be equipped with external overload protection device. It is strictly prohibited to do no-load test without water.

Well submersible pump is a clean water pump, it is strictly prohibited to dig a new well to extract mud and silt. The voltage grade of the well pump is 380/50HZ, and the submersible motor with other voltage grades needs to be customized. Underground cables must be waterproof and must be equipped with starting equipment, such as distribution box, etc. 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. In abnormal cases, the protection device should be timely tripping. When installing and using the pump, the pump must be reliably grounded, and it is prohibited to push and pull the switch when the hands and feet are wet. Before installing and maintaining the pump, the power must be cut off, and the place where the pump is used must be clearly marked "anti-electric shock". Before going down the well or installing the pump, the motor must be filled with distilled water or clean cold water without corrosion, and the intake/drain bolts must be tightened. When testing the pump on the ground, water must be poured 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. When using the pump, the lift and flow range specified by the pump must be strictly followed to prevent the pump from having a large flow at low lift or a large pull at high lift, which will lead to serious wear and tear of the thrust bearing and other parts and components, and cause the motor to overload and burn out. After the pump is put into the well, the insulation resistance between the motor and the ground should be measured, which should not be less than 100MΩ. After the start, the voltage and current should be observed regularly, and the motor winding insulation should be checked to see if it meets the requirements; if the temperature of the pump storage location is below the freezing point, the water in the motor cavity should be drained to prevent the water in the motor cavity from freezing and damaging the motor due to low temperature.
