A: Diesel flow quantitative metering, which can be performed using the flow quantitative control cabinet system, while diesel flow measurement, which can be measured using ultrasonic flow meter, ultrasonic flow meter, measurement precision ...

1. First confirm the installation environment of the inverter I. Operating temperature. The inverter is a high-power electronic component, which is very susceptible to the influence of working temperature, and the product is generally required to be 0-55 °C, but in order to ensure the safety and reliability of the work, it should be considered to leave room for use, and it is good to control it at 4 ...

As we all know, coal enterprises are large consumers of electricity, and their electricity consumption costs account for a considerable proportion of their production costs. In coal mining enterprises, due to the fact that the production equipment generally meets the characteristics of long service life, the phenomenon of large horse-drawn trolleys caused by large model selection, serious waste of electric energy, and the operation efficiency of equipment is often ...

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 ...

Xu Shaoshi, Director of the National Development and Reform Commission, Gao Yan, Vice Minister of Commerce, Minister of Economy, Trade and Industry of Japan ...

The electromagnetic flowmeter is roughly said to be composed of two parts: a sensor and a converter, and the form of the flowmeter can be divided into two types: integrated and split. The detailed rules say that it is mainly composed of a magnetic circuit system, a measuring catheter, an electrode, a lining, a shell and a converter. Electromagnetic flowmeter ...

Frequency converters and soft starters are actually two completely different products. The inverter is mainly used in the place where the motor regulates the speed, and the inverter has the performance of soft starter and other starters, and at the same time, it also has great advantages over other starter devices in terms of starting characteristics. At the start of the current ...
