1. Application and development of magnetic flap level gauge in liquid chlorine tank level detection Liquid chlorine is a high-risk and highly toxic substance, which is highly corrosive, and once it causes leakage, it will cause great harm to the environment and the human body, so it is particularly important to ensure the safe operation of the liquid chlorine tank. And accurate and reliable control ...

Fuji Electric inverter has many precautions during use. Here are some methods to learn. 　　The ambient temperature has a great influence on the service life of the inverter. For every 10°C, the service life of the inverter will be halved, so the ambient temperature and inverter dissipation must be solved.

The Semiconductor Industry Association (SIA) recently announced that global semiconductor sales in June 2017 reached $32.6 billion, up 2.0% compared with the previous month; This is a 23.7% surge compared to the same period last year. Semiconductor sales in the second quarter of this year were US$97.9 billion, up 5.8% quarter-on-quarter and 23.7% year-on-year; This year...

Why should the fan be equipped with a frequency converter? Today, I will discuss it with you. Factory boiler fans, industrial fans, hotel fume fans, etc. all use inverters, so why do fans use inverters? We all know that many air ducts will have a valve, control ...

In the summer, in terms of the inverter that is indispensable for equipment control and speed regulation, the scorching weather is the hard injury of the inverter's heating. A large number of existing studies and practices show that the failure rate of the inverter will increase with the increase of temperature, the service life will decrease with the increase of temperature, and the ambient temperature will rise.

A common phenomenon of frequency converter interference 1. As soon as the inverter of the heat exchange station is opened, the pressure transmitter jumps randomly; 2. In the water supply controlled by the inverter, the pressure transformer is used as the signal to collect the pressure, and the pressure transformer is interfered by the inverter; 3. When the inverter starts the motor, the voltage transformer signal is unstable and beats badly; 4. ...

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.
