Stainless steel submersible pump product development direction is: continue to expand the use of pump products, and continuously improve the quality of pump products, as soon as possible the development of China's pump products to catch up with the world's advanced technology.
Stainless steel submersible Pump performance range is very large, large pump flow up to hundreds of thousands of m3 / h or more, while the micro-pump flow in the tens of mL / h the following. The pressure can be up to more than 1000MPa from the normal pressure, the temperature of the liquid can be transported to the lowest -200 ℃ below the maximum up to 800 ℃ or more. Pumps can be used to transport liquids (water, sewage, etc.), acids and alkalis, emulsions, suspensions, and liquid metals.
With the modern industrial production and the continuous development of science and technology, stainless steel submersible pump products are also toward the large-scale, high-speed and specialization. In recent years, the development of large foreign pumps more, such as 1500mm diameter submersible pumps, impeller diameter of 7m submersible axial flow pump, 2000kW shielded pump, flow 2000t / h of the marine screw pump. With the cavitation problem, material problems continue to solve, pump speed more and more to the direction of high-speed development. Large-scale high-speed pump economy is quite significant, both to reduce the volume, but also reduce the weight. Foreign marine boiler feed pump speed has reached 23000r / min, petrochemical industry has been with 34000r / min of the adjustment pump, 22000r / min axial piston pump and 30000r / min rotary piston pump also appeared one after another. With the development of industrial production, more and more requirements of the pump, the conditions are more and more special. Such as special-purpose corrosion-resistant submersible pumps, plastic pumps, shielding pumps, metering pumps, sewage submersible pumps, electromagnetic pumps will be developed rapidly
