Mixed flow pumps1. The working principle of the mixed flow pumpBecause the impeller shape of the mixed flow pump is between the centrifugal pump impeller and the axial flow pump impeller, therefore, the working principle of the mixed flow pump has both centrifugal force and lift force, relying on the combined effect of the two, the water flows out of the impeller at a certain angle with the shaft, and the water is lifted to a higher place through the volute chamber and pipeline.2. General characteristics of mixed flow pumps(1) Compared with centrifugal pumps, the head of the mixed flow pump is lower and the flow rate is larger, and compared with the axial flow pump, the head is higher and the flow rate is lower. It is suitable for drainage and irrigation in plains and lake areas.(2) Water is sucked in and outflowed at an angle to the impeller shaft along the flow direction of the mixed flow pump, so it is also called an oblique flow pump.Commonly used agricultural pumpscentrifugal pumpCentrifugal pump models, varieties and specifications and their variants are the most common among agricultural pumps. According to the way of water flowing into the impeller, the number of impellers, whether the pump body can be self-priming, and the size and variety of supporting power, centrifugal pumps include single-stage single-suction centrifugal pumps, single-stage double-suction centrifugal pumps, multistage centrifugal pumps, self-priming centrifugal pumps, electric motor pumps and diesel engine pumps.1. Single-stage single-suction centrifugal pump

The old pump models are BA, B type single-stage single-suction centrifugal pump, in the 80s, China according to international standards and the actual situation of drainage and irrigation machinery, the centrifugal pump products for upgrading and development work, and the production of IB type, IQ type single-stage centrifugal pump series products, has been listed as national professional standards and industry standards.Single-stage single-suction centrifugal pump, water enters the impeller from the axial single side, and the impeller has only one, so it is called a single-stage single-suction centrifugal pump. Its characteristics are, compared with mixed flow pumps and axial flow pumps, the head is higher, the flow rate is small, the structure is simple and it is easy to use.IQ type single-stage single-suction centrifugal pump (also known as light and small centrifugal pump) is designed for national conditions and to meet the requirements of simple structure, light weight, low price, good performance and convenient supporting equipment, a total of 84 products, divided into 3 derivative series, 413 specifications and models.
