very large, and the products with obvious price advantages (mainly refer to centrifugal blowers and general-purpose centrifugal and axial compressors), and high-tech industries and newly developed high-tech products (mainly refers to centrifugal compressors for ethylene plants with a capacity of more than 600000 tons, natural gas pipeline transmission compressors, high-pressure oil field gas injection compressors and compressors for large air separation units) , it is not competitive. In the ber case, the impact will be small after the market is opened. However, the enterprises producing such products should have a sense of urgency, focus on improving the development and innovation ability, improve the technical content and grade of products, and narrow the gap with foreign countries. In the latter case, it will be greatly impacted after the market is opened. 鈶� generally used Small and medium-sized ventilators in transit are the vast majority of products in the fan industry, belonging to large quantities and a wide range of products. It is equivalent to the situation mentioned above that the products have low cost and price advantage. After China&锛�39;s accession to the WTO, it will be conducive to expanding exports, and the opening of the domestic market basically does not pose a threat. For example, the world&锛�39;s more famous Fan enterprises are mainly German TLT company Among them, Shanghai Blower Factory Co Ltd. has introduced German TLT technology, Shenyang Blower Factory has introduced Danish novenko technology, Chengdu electric machinery factory and Shenyang Blower Factory have introduced German k.k.k technology, and British Haodeng company has established a wholly-owned enterprise in China Enterprises have already participated in the domestic fan market competition. From the price comparison of such products, taking the prices of Japanese manufacturers as an example, the prices of Japanese manufacturers&锛�39; fans are now twice that of domestic fans. After China&锛�39;s accession to the WTO, the tariffs have been reduced, but their prices are still 50% ~ 60% higher than those of domestic products. This shows that such products will not be competitive after China&锛�39;s accession to the WTO It

With the rapid development of variable frequency speed regulation technology and programmable controller, as well as its wide application, powerful function and convenient use, it has become one of the main devices of modern industrial automation and is widely used in industrial production, applications in other areas, such as civil and Home automation, have also developed rapidly. Due to the flexible and convenient application of frequency conversion and programmable logic controller, it is also widely used in constant pressure water supply system. Using PLC as the central control unit, the working pressure of the water supply system can be quickly adjusted according to the system state by the combination of frequency converter and Pid, thus achieving the goal of constant pressure water supply and improving the working stability of the system, the good control effect and obvious energy-saving effect are obtained. 2. System Structure Frequency conversion constant pressure water supply system principle as figure 1, it mainly has PLC, frequency converter, pressure transmitter, liquid level sensor, power and control circuit and pump group comb. The user understands and controls the operation of the system by means of the indicator lights and buttons on the Control Panel and the transfer switch. Through the pressure transmitter installed on the outlet pipe network, the outlet pressure signal is changed into 4 ~ 20mA standard signal and sent to the PID regulator built in the frequency converter. By comparing the PID operation with the given pressure beter, the 4 ~ 20mA beter is obtained, 4 ~ 20mA signal is sent to frequency converter. The control system uses the frequency converter to control the pump speed in order to adjust the water supply. According to the different water consumption, the frequency of the frequency converter to adjust the pump speed is different, setting an upper limit frequency and a lower limit frequency detection in the frequency converter setting, when the water consumption is large, the frequency converter quickly rises to the upper limit frequency, at this time, the frequency converter outputs a switching signal to the PLC; When the frequency converter output reaches the lower limit frequency, the frequency converter also outputs a switching signal to the PLC; the two signals will not be produced simultaneously. When any signal is generated, the signal is fed back to the PLC, and the PLC can switch the AC contactor group by setting an internal program to drive the i/o switch output, so as to coordinate the number of pump motors put into operation, and the completion of the motor start-stop, frequency and power-frequency switching. By adjusting the number of motors put into operation and controlling the frequency conversion speed of one motor in the set, the working pressure of the system pipe network is always stable, and then the aim of constant pressure water supply is achieved. Working principle the system has two modes of operation: Manual and automatic. Manual Mode, press the button to start and stop the pump, according to the need to control the start and stop of 1 # ~ 3 # pump, this mode is mainly used for equipment
