At present, the equipment configuration of industrial and domestic water supply systems basically meets the requirements of energy-saving, safety and reliability. However, in the water-lifting and water-conveying systems, due to the aging of the equipment, the large power and high voltage of the pump units, to increase the investment in speed control facilities, the current can not do energy-saving economic operation. As most of the fluid equipment is durable product equipment, it is rare to upgrade and update it once invested and built. Therefore, it is suggested that the manufacturing units of fluid equipment should aim at the use of new technology in the whole process of R & D, design and manufacture, new Product Development, more user feedback to improve the product, such as the pump impeller, pump shell, pump seat wall using polymer super-slip metal anti-corrosion coating surface treatment, dynamic seal parts using high-efficiency packing. It is suggested that the construction and use units should have a sound and long-term consideration for the investment to ensure the energy-saving, economic, safe and reliable system. The fluid equipment in the water supply system is relatively simple and efficient, and can be used together with other mechanical and electrical equipment in the water supply project. As the water supply industry in the user to the frequency converter put forward the following requirements. (1) frequency converter efficiency to high frequency converter is used to control the pump unit. It is connected between the power supply and the motor, adding an additional energy-consuming device to the whole system. The water supply industry attaches great importance to efficiency. In the technical specifications of the inverter products say that the product efficiency is greater than 0.98. This is too general, because the frequency converters used in industry, in addition to the main body, have auxiliary auxiliary equipment, such as multiple phase-shifting transformers, PWM rectifiers for the incoming reactor, filters to suppress the harmonics after the INVERTER, pump equipment in the water-cooling system, etc. , they are all energy-consuming equipment and should be described in the technical specifications. (2) frequency converter should have low harmonic content. The input stage of frequency converter is rectifier,
