Spiral Centrifugal Submersible Pump

Product use:
This product is widely used in chemical, petroleum, pharmaceutical, mining, paper, cement, steelmaking, power generation, coal processing industry and urban sewage treatment plant water supply and drainage system, municipal engineering, construction sites and other industries to convey particles and fibers of sewage and dirt, can also be used to pump clean water and corrosive media.
Product use conditions:
1. Three-phase AC power supply with rated voltage of 380V and frequency of 50Hz.
2. The temperature of the conveying medium does not exceed 40 ℃, the PH value is 4~10, the density is less than 1.1 × 103kg/m3, and the volume of the solid phase can reach 20%.
Product performance and structural characteristics:
1. The Q-H curve is steep, the smooth operation area of the pump is wide, and the curve drift is small in the case of pumping complex media.
2, high operating efficiency, high efficiency area wide, low operation and maintenance costs.
3. The net suction pressure head is low, and the anti-cavitation ability is strong; the shutdown water level is low, which greatly reduces the construction cost of the pool.
4. Smooth drooping power curve, no overload area.
5, no blockage, no winding.
6, soft transport, can be intact to transport live fish, fruits, vegetables and other fragile substances; in the sewage plant activated sludge reflux process, the destruction of the bacteria micelle is only 1/10 of other forms of pump.
7. Medium with high solid content can be transported, for example, mud with solid content as high as 20% can be transported.
8. Advanced Ansys-CFX software is used to optimize the design of hydraulic components, which improves the hydraulic performance of the pump and the pump efficiency reaches the advanced level.
9. The advanced Ansys software is used to scientifically calculate and analyze the pump structure, which improves the life of bearings and mechanical seals, and reduces the vibration and noise of the pump.
10. The cable outlet adopts a special structure, which eliminates water leakage, electric leakage, short circuit and stator coil burning caused by accidental factors such as artificial pulling, broken cable jacket and cable aging, and effectively reduces the probability of failure in the upper part of the whole machine.
11, built-in a number of early warning sensors, in the external control cabinet with lack of phase, short circuit, over-current and water level control and other protection, can achieve the entire system of remote control and monitoring.
12. The bearing adopts imported brand-name products with reliable structure.
13. The product uses a double-sealed structure to increase the reliability of the seal.
14. A self-circulating cooling system is applied to the high-power submersible pump, and the water outlet pressure of the impeller itself is used to ensure that the motor is always under the circulating cooling of the water when the pump is running.
15. The impeller of the water pump adopts a large channel non-clogging impeller, and the blade profile is designed according to the streamline to ensure the large channel flow and smooth operation.
16. A replaceable wear-resistant sleeve is installed between the impeller and the lower end of the volute to keep the pump running efficiently.
