1. Analysis of common faults in the main circuit The main circuit is mainly composed of three-phase or single-phase rectifier bridges, smoothing capacitors, filter capacitors, IPM inverter bridges, current limiting resistors, contactors and other components. Many of these common faults* are caused by electrolytic capacitors. The life of an electrolytic capacitor is mainly determined by the ...

The people are the foundation of the country, the valley is the life of the people, diligence and thrift are the fine traditions of the Chinese nation, and food security is an important foundation for national security. At present, the security situation at home and abroad is complex, and the sudden outbreak of the epidemic has caused multiple challenges to global food security. October 16, 20201 is World Food Day.

Instrumentation spreads through all sectors of the national economy and penetrates into all corners of people's lives. For example, in the machinery manufacturing industry, the static and dynamic performance of the product is tested, the processing process is controlled and monitored, and the fault diagnosis in the operation of the equipment is diagnosed. In the electric power, chemical, petroleum industries, ...

Fujifilm portable ultrasonic flowmeter is used to check the flow rate at the outlet of a water pump in the field Error analysis in the flow measurement process Check for abnormal readings from the in-line flow meter Avoid process interruptions and the background of more expensive tube opening costs Waterworks are mainly used to treat water, and generally have the following processes.

From December 23 to 24, 2017, the 11th China-Japan Energy Conservation and Environmental Protection Comprehensive Forum, jointly organized by the National Development and Reform Commission and the Ministry of Commerce, the Ministry of Economy, Trade and Industry of Japan and the Japan-China Economic Association, was held in Tokyo. More than 800 government officials, experts, scholars, and entrepreneurs from China and Japan attended the event.

The source of AC converter interference comes from interference from the external power grid. Harmonic interference in the power grid mainly interferes with the frequency converter through the power supply of the frequency converter. There are a large number of harmonic sources in the power grid, such as various rectifier equipment, AC and DC interchange equipment, electronic voltage adjustment equipment, nonlinear loads and lighting equipment.

The main reason why the ultrasonic flowmeter replaces the traditional ordinary flowmeter is that it is more accurate in the measurement results, will not be disturbed and affected by any external factors, ensures more safe and reliable performance in the work, and the measurement range will be wider. In order to play better ...

On June 12, 2019, the 17th China International Environmental Protection Exhibition (CIEPEC2019) will be held at the China International Exhibition Center (Jing'an Zhuang Pavilion) in Beijing. More than 700 domestic and foreign exhibitors gathered together to showcase their environmental protection technologies and products. ...

Fujifilm ultrasonic flowmeter is a non-contact flowmeter that has only been applied with the rapid development of integrated circuit technology in the past ten years, which is suitable for measuring fluids that are not easy to contact and observe, as well as large pipe diameter flows. Together with the water level gauge, it forms an open channel flow meter for flow measurement of open water ...

The signal of the catalyst feed control valve of a company's DCS system (distributed control system) intermittently appears OOP (output signal line break) alarm, and the control valve is fully opened instantly, resulting in abnormal fluctuations in catalyst flow, which seriously affects the safe and stable operation of the device.
