The QJ series well submersible pumps and submersible motors (hereinafter abbreviated as submersible pumps) produced by our company are based on national standards and incorporate advanced concepts of domestic and foreign submersible pumps and submersible motors, combined with the advantages of the company's mechanical processing, and fine workmanship Made from. With energy-efficient, high reliability, long life and other characteristics. The company's submersible pump market is positioned as: urban and rural tap water, industrial and mining, transportation, oil field water supply and other places that require higher product quality, but also suitable for agricultural irrigation.
I. Features of the company's production of submersible pumps
1. Advanced design concept. The structure design of submersible pumps and submersible motors draws on domestic and foreign advanced concepts; draws on the hydraulic model design of internationally advanced submersible pump companies such as Germany; and uses domestic famous electromagnetic electromagnetic calculation software to optimize the design of submersible motors.
2, excellent equipment, advanced and reasonable technology, perfect tooling, strict quality control system, well-trained and experienced staff, to provide product quality and quality assurance.
3, the product parts and materials, supporting materials (such as: motor silicon steel, water magnet wire, cable), standard parts and other selected IS9000 certified well-known manufacturers.
4, submersible pumps, submersible motors highlight the concept of green. Energy-saving and high-efficiency; long maintenance cycle; long service life; frictional sub-parts can be replaced as much as possible. Reduce unnecessary waste of social resources and reduce user's use and maintenance expenses.
Second, the use of submersible pumps
Submersible pumps can operate long-term under the following conditions.
Power: frequency: 50Hz; rated voltage: 380V (three-phase AC power).
Installation status: To submerge the submersible pump into the water, do not dive into the depth of 70 meters. Submersible pumps are installed vertically (some models can be mounted horizontally. See the sample description for details).
Operating flow: The flow of the submersible pump during operation should not be greater than 1.2 times the rated flow (refer to the flow corresponding to the high point of the submersible pump).
Water medium conditions:
(1) The temperature is not higher than 20 °C;
(2) The solid content (by mass) is not more than 0.01%;
(3) PH value between 6.5 and 8.5:
(4) The content of hydrogen sulfide is not more than 1.5 mg/L;
(5) The hydrogen ion content is not more than 400 mg/l;
Third, the use of submersible pumps outside the scope of conditions (if the conditions of use outside the scope of paragraph 2, please specify when ordering)
1, dry precipitation submersible pump:
The dry precipitation of open-pit mines, underground buildings, and pits is often reduced from a few meters above the surface to several hundred meters. The head of the selected submersible pump is related to the final precipitation level. Initial dry precipitation, the actual head is very low, the submersible pump's operating flow far exceeds the rated flow. The use of a standard-configured submersible pump will cause accelerated wear of the thrust bearings on the submersible motor, causing the motor to burn out. The company can provide solutions that enable users to safely and reliably use a submersible pump to dry out precipitation.
2, horizontal installation submersible pump
The following submersible pumps can be installed horizontally.
150QJ25-605/1 to 32.5/5
3, hot water submersible pump:
When the water temperature exceeds 20°C, the company may provide hot water submersible pumps for hot water applications such as hot springs.
4, under the suction submersible pump:
For pools and large wells, the submersible pump cannot pump water because the water level drops to the water inlet when the submersible pump is running. A water-absorbing cover can be installed on the submersible pump so that the suction port of the submersible pump is at the bottom of the motor (submersible pump with suction cover installed, and the water level should be higher than the inlet shell when starting).
5. Submersible pumps resistant to seawater and other corrosive media:
The company can change the surface protection of the submersible pump by changing the material of the submersible pump so that the submersible pump can be applied to different corrosive media.
6, sand submersible pump:
When the sediment concentration in water exceeds 0.01%, the standard configuration of the submersible pump will reduce the operating life and maintenance cycle. The company adopts the erosion protection technology to provide the user with a sand-resistant submersible pump (all products in the sample can be transformed into sand Submersible pumps).
7, can provide 60Hz and rated voltage of 220V, 660V submersible pumps.
In addition, we can provide complete solutions based on the user's other special conditions of use.
Four, selection instructions
When the user selects the order for the first time, please provide the following parameters.
User requirements for traffic;
Minimum well diameter and well completion depth; well static water level, dynamic water level and water inflow (provided by the well drilling team); height difference and outlet pressure requirement from wellhead to water delivery pipe outlet; diameter, material and length of surface water transfer pipe; The number of elbows, valves, voltage, frequency, and power capacity.
V. Complete range
Submersible pumps, submersible motors, cables, water pipes, elbows, seals, bolts, nuts, cable joints, splints, check valves (according to the approval of the factory)
The above can be supplied as a complete set according to the user's requirements, or it can be partially delivered. When ordering, please specify in the contract. (Our factory can also provide pressure gauges, gate valves, starters, protectors and water level pressure controllers, etc., according to user requirements)
