Pump industry in the future will be how to develop?

in the development of science and technology, the age in progress, all products are updated in the iteration. In such circumstances, as our traditional water pump industry, how to development can not be eliminated? Following a brief introduction about pump industry development direction in the future.

1, large capacity, high lift.

after pump capacity increases, can reduce equipment and reduce the construction cost and save energy. Easy to use management and automation, and can also improve the technical and economic indexes and operation reliability of the unit. High speed

2.

in the 1960 s, due to cavitation and material problem, the speed of the pump are generally only to 3000 r/min, in recent years, with the continuous development of science and technology, the rotational speed of the pump is higher and higher. For pump, improve the speed of single-stage pump head can be improved. Therefore, in the total lift at the same time, can reduce pump series, shorten the length of the pump shaft, reduce the volume, weight, saving raw materials and the manufacturing cost. Feed water pump, such as the United States of 660 mw unit when the speed increased from 3000 r/min to 7500 r/min, the single stage Yang can reach 1143 m, series from phase 5 to level 2, three-quarters of the reduction in weight. After the speed increase, therefore, brought about by the economic benefit is remarkable.

3 high efficiency.

pump for general machinery products, its power consumption is objective. Therefore, improving the efficiency of pump to save energy is of great significance. Our country began in the early 1970 s to the low efficiency of pump, such as centrifugal pump efficiency is lower than 60% of products technical renovation, update, make the improved feed water pump efficiency reached 79%. Respectively introduced a new technology in China in the 80 s, the production of the third generation of high pressure boiler feed water water pump, its efficiency is above 82%.

it is worth noting that in 1995, the pump running status survey results show that the actual operation of centrifugal water pump in China efficiency 10% ~ 30% lower than the developed countries. Therefore, in addition to improve the efficiency of the pump itself, also needs to improve its efficiency in the system.

4 high reliability.

due to the pump to develop in the direction of large capacity, high speed, so more and more high to the requirement of reliability. Because suddenly, only the pursuit of high efficiency and reliability, the energy cost savings in operation can't more than offset due to stop the economic losses caused by the pump. Therefore, to improve efficiency at the same time, the reliability should be in first place. The reliability of the pump from the aspects such as design, manufacturing to installation operation should be guaranteed.

5 low noise.

like air pollution, water pollution, noise pollution is harmful to people's health. At present, many countries on the mechanism of noise control, noise detection technology, as well as to the noise limits, etc have made a lot of research, and formed an emerging discipline.

6 automation.

with the development and application of computer technology and network technology, now in more than 300 mw unit has fully realized computer network monitoring and control of DCS, the distributed computer control system or collecting and distributing control system. Abroad have to evenly into the DCS of power plant electrical part of the monitoring control system, so as to realize the computer network system of the whole power plant monitoring control and management, become a coal-fired power plant automation. In the DCS system, pump is no longer a single control, but the network monitoring and control. It can realize automatic start-stop of pump, to realize online real-time monitoring parameters such as flow, pressure, temperature, display and control, and automatic on-line fault diagnosis and chain and protection.
