Centrifugal Multistage Water Pump
MD type centrifugal multistage water pump is a multistage and segmental centrifugal water pump, which is suitable for water supply and drainage in mines, factories and cities. It is designed for conveying without solid particles and abrasives,clear water without suspended solids or other liquids with physical and chemical properties similar to that of clear water. The temperature of the transported liquid is - 20 ℃ ~ 80 ℃.
The stage casing is one of the most important parts of the centrifugal multistage water pump. The main materials of the stage casing of the Centrifugal Multistage Water Pump are cast iron, cast steel or stainless steel. The stage casing of the centrifugal multistage water pump is made of cast steel and stainless steel, with a service life of up to 5 years. Better material also ensures the service life of the centrifugal multistage water pump.
The diffuser is the energy conversion device of centrifugal multistage water pump. Its function is to collect the liquid thrown out by the impeller, so as to reduce the flow rate of the liquid. After transforming part of the speed energy head into the pressure energy head, the diffuser can be evenly introduced into the next stage or discharged through the diffusion tube.
The function of diffuser is the same as volute, which is mostly used in centrifugal multistage water pump. According to its structure, it can be divided into radial diffuser and runner diffuser. The forward diffuser and reverse diffuser of runner type guide vane are cast together. There is a continuous flow channel in the middle, which makes the liquid flow in the continuous flow channel, and it is not easy to form dead angle and sudden diffusion. The speed change is relatively uniform and the hydraulic performance is good, but the structure is complex and the manufacturing process is poor.
