According to sources, the Ministry of Industry and Information Technology is working out a "strategic plan for going out of the manufacturing industry" to strengthen overall coordination and guidance on the classification of enterprises. In order to cope with the increasingly globalized industry development, we must understand the status quo and development trend of the international pump and pump station.

The design and manufacturing level of the pump is increasing. The pump station will be automated With the continuous improvement of the design and manufacturing technology and application technology of the water pump, the manufacture and production of the water pump is increasing in size, capacity, high lift, high speed, serialization, and general use. Development and standardization. The automation level of the pumping station is getting higher and higher.
1. Large-scale and large-capacity In recent years in 2009, large-scale water pump technology has developed rapidly. The diameter of the giant axial-flow pump has reached 7m, and the diameter of the submersible pump impeller has reached lm. China's largest production capacity of axial pump 6000kW, mixed-flow pump 7000kW, centrifugal pump 8000kW; high pressure boiler feed pump unit capacity of 60000kW; new centrifugal submersible pump pumping flow has reached 1800m3 / h, the corresponding head llOm, the maximum water output of 28800m3 / h, and there is a trend of further expansion. In the area of ​​pumping stations, a large number of new large-scale pumping stations have also emerged, such as “egg†type pump stations, inlet and outlet pipes, and pool-building pumping stations. With the promotion and application of submersible pumps in drainage, a number of large and medium-sized pumping stations with small space, investment provinces and new structures have emerged correspondingly, such as the wet well pump room structure constructed of steel or reinforced concrete.
2. High lift, high speed With the continuous improvement of the pump cavitation, material strength and other issues, the speed of the water pump is also faster and faster. In the 1980s, the international level of multi-stage centrifugal pump speed was 7500r/min, which has now increased to 10000r/min. The increase in speed will inevitably increase the lift of the pump. In 2009, the single-stage lift of the boiler feed pump has broken the record of 1000m, and the lift of the multi-stage pump can reach more than 2000m. To further achieve high lift, it is imperative to increase the pump speed. After that, with the continuous advancement of technology, the rotational speed of the pump has been further developed toward higher speeds. In the water pump industry, this high-speed development trend is global.
3. Serialization, generalization, and standardization The serialization, generalization, and standardization of products (referred to as "three") are the inevitable requirements of modern industrial production processes. In 1975, the International Standards Association developed the main dimensions and specifications of a single-stage centrifugal pump with rated pressure of 720 kPa (ISO 2858-1975E). The performance range of this standard pump is: the flow rate is 6.3-400m3/h, and the head is 25-125m. In 2009, pumps that meet this specification in Europe have been sold as standard pumps. Since 1958 in China, we have done a lot of work in terms of uniform models, series classifications, and stereotyped dimensions. The main components of the pump brackets, suspensions, and bearing brackets have already been series of standards. "The degree continues to increase.
4. The automation level of the pumping station has gradually increased In recent years in 2009, the automation equipment of pumping stations has become more and more perfect, and the level of automatic control has become higher and higher. The modern pump station can realize automatic control from unit startup, monitoring operation, shutdown to multi-stage pumping station system adjustment, optimization dispatch, etc. Computer technology and network system are becoming more widely used in the automatic control of pump stations, and the management level is also Gradually improve.
With the development of science and technology such as atomic energy and fuel industry, it will further require the development of various special water pump products with high speed, high temperature and high pressure, high efficiency, and large capacity; and it also requires the continuous improvement of the quality of existing conventional products. Level. In order to achieve this goal, we must innovate in a series of links such as basic theory, computational techniques, model tests, measurement methods, material selection, and processing techniques. In terms of the design and operation management of the pumping station, measures should be actively taken to maximize the efficiency of the working pump and improve the automation level of the pumping station.
