I. Product Overview: QJ Type Submersible Pump for Well (Deep Well Pump)
The QJ type submersible pump for well use is a water lifting equipment that directly connects the motor and pump and operates submerged in water. It is suitable for extracting groundwater from deep wells, as well as for water lifting projects in rivers, reservoirs, canals, etc.: mainly used for agricultural irrigation and drinking water supply for humans and livestock in highland and mountainous areas, and also available for urban, industrial, railway, mining, and construction site water supply and drainage.
QJ Type Submersible Pump for Wells (Deep Well Pump) Product Features:
Motor and pump integrated, submersible operation, safe and reliable.
2. No special requirements for well pipes or pump pipes (i.e., steel well pipes, cement well pipes, earthen well pipes, etc. are all acceptable; under permitted pressure, steel pipes, rubber hoses, plastic pipes, and others can all be used as pump pipes).
3. Easy installation, operation, and maintenance; takes up minimal space; no need to construct a pump house.
4. Simple structure, material-saving.
The suitability of conditions for submersible pump use, and proper management, are directly related to its service life.
4. QJ Type Submersible Pump for Well Use (Deep Well Pump) Application Conditions:
The QJ type submersible pump for well use can be continuously operated under the following conditions:
Rated at 50HZ frequency and 380±5%V voltage, a three-phase AC power supply.
2. The pump's intake must be below 1 meter of the dynamic water level, but the submersion depth should not exceed 70 meters below the static water level, with the motor's lower end at least 1 meter above the bottom of the well.
Water temperature should generally not exceed 20°C.
4. Water Quality Requirements: (1) Sand content in water not to exceed 0.01% (by weight).
(2) pH range: 6.5~8.5
(3) Chloride ion content not exceeding 400 milligrams per liter.
5. The well must be straight and the wellbore smooth; no pipe misalignment is permitted.
