In the process of motor starting (acceleration), the motor should not only bear the load torque of steady speed operation, but also bear the acceleration torque, if the production machinery has no special requirements for the starting (acceleration) time, the starting (acceleration) time can be appropriately extended to avoid the peak current. If the production machinery is ...

Introduction to the main products and functions 1.1 Water supply frequency conversion cabinet (1) Ordinary water supply frequency conversion cabinet: this product can control a water pump motor frequency conversion water supply and a water pump motor power frequency water supply at the same time, and the power of the water pump motor is between 0.75KW and 5.5KW. The water supply capacity of the product can meet the needs of ...

After the inverter runs uninterrupted for a long time, the high temperature generated inside has serious hidden dangers to the operation of the inverter, especially in summer. The ultimate operating temperature of the inverter inside the inverter is generally 125 °C, and the temperature of the inverter inverter module and IGBT can sometimes reach 110 °C.

As the cornerstone of modern industry, manufacturing is one of the important factors that distinguish the development level of various countries and regions. The manufacturing industry includes a wide range of materials, energy, equipment, tools, capital, technology and manpower, etc., which can be said to be inseparable from the manufacturing industry. ...

As the two most important forms of flow meter in the current flow measurement field, how to choose? Xiaobian elaborates on the characteristics of the following two from the following aspects, hoping to provide some suggestions on selection. 1. Ultrasonic flowmeter Measuring principle of ultrasonic flow meter: ...

1. The working principle of Fujifilm ultrasonic flowmeter A complete set of Fujifilm ultrasonic flowmeter is composed of ultrasonic generator, ultrasonic receiver, electronic circuit, flow display, accumulation system and other structures. The principle of ultrasonic flowmeter is shown in Figure 1. As you can see from Figure 1, ...

With the conclusion of the 19th National Congress of the Communist Party of China, the spirit of the major conferences has been newly conveyed. Among them, General Secretary Xi Jinping said that in order to practice the concept of green development, we must establish and practice the concept that lucid waters and lush mountains are invaluable assets, and to protect the ecological environment is to protect productivity, and to improve the ecological environment is to develop the ecological environment.

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.

Handheld ultrasonic flowmeter is an essential tool instrument for flow detection. It is designed to improve the convenience of measuring the flow rate, with high measurement accuracy, large range ratio, no pressure loss, no moving parts, and small size, light weight, only need to install the sensor on the outer wall of the pipe.

The measurement of urban pipe network flow is an important task of water supply enterprises in pipe network management. In the past few years, our company has used Japan Fuji portable ultrasonic flowmeter to measure water consumption for large water users, and persuaded and alleviated the "supply and demand" contradiction between these enterprises and companies with scientific data; Especially...

With the increasing shortage of water resources, the requirements of water supply enterprises for the metering performance of water meters are gradually increasing. In order to meet the measurement requirements of the water supply industry, various metering instruments have been continuously improved, from the traditional mechanical water meter to the electronic water meter. In recent years, electronic technology, computer technology and network communication technology ...

1. Why is the leakage circuit breaker easy to trip when using the inverter? This is because the output waveform of the inverter contains higher harmonics, and the motor and the cable between the inverter and the motor will generate a leakage current, which is much larger than that when the motor is driven by the power frequency. ...

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 ...

Following the last release of the circuit breaker Q&A, we have received new circuit breaker inquiries one after another, and this time we have selected the questions about the "protection function" with a high interest rate for answers: (1) What exactly is a "protection function"? (2) How should I look at the "action characteristic curve"? (3) When selecting, facing ...

Fuji Electric inverter inverter fault code fault code fault after the corresponding treatment method is given. 　　OC alarm. Keyboard board LCD display: add, subtract, constant speed overcurrent. For the OC alarm with high current in a short time, under normal circumstances, there is a problem with the current detection circuit of the driver board, and the module may also ...

1. Method errors It refers to the error caused by the imperfection of the measurement method used, the imprecise theoretical basis, and the inappropriate modification and simplification of some classical measurement methods, that is, all the factors that are not reflected in the expression of the measurement results, but in fact these factors play a role...

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. ...
