Mixed flow pump types and structure:
Mixed flow pump is generally divided into two types: guide vane mixed flow pump and spiral case type mixed flow pump. Volute mixed flow pump system consists of a bearing body, a pump body, impeller, pump shaft seal device and pump cover etc.. Guide vane mixed flow pump is also called the diagonal flow pump. Vane type mixed flow pump and spiral case type difference mainly in the pump body, vane type mixed flow pump generally set a few usually twisted blade type space guide vane device. After the liquid flows through the impeller, the liquid flows along the axial direction. Pump body looks like a drum with a big belly drum shape, compared with the axial flow pump. This kind of pump is generally divided into two types: internal structure is basically the same vertical and horizontal,. General large diameter vertical more. Small diameter vertical guide vane mixed flow pump and centrifugal shallow well pump is similar, the pump is often referred to as the mixed flow type of agricultural drainage pump. Mainly because of simple structure, easy to move, suitable for farmland irrigation.
Mixed flow pump working principle:
Due to the mixed flow pump is composed of centrifugal and axial flow pump, so when the impeller in the prime mover driven by rotation, the force of liquid is two-way, both axial thrust and centrifugal force. So it is a kind of pump between the axial flow pump and the centrifugal pump. When the mixed flow pump speed is lower than the axial flow pump, higher than the centrifugal pump, usually between 300-500. At this time the head is higher than the axial flow pump, but the flow rate than the axial flow pump is smaller than the centrifugal pump. In addition to the use of mixed flow pump as agricultural irrigation, often is used in city drainage, can be used as the circulating water pump in thermal power station.
