Less noise and more health

Going out of the "official" and sticking to the people-oriented, can not forget this; less bureaucratic, more people, can gather popularity. Similarly, in the life of less noise, more clean, in order to be healthier. Noise pollution, water pollution, air pollution and garbage pollution are listed as the four major cities that must be controlled by the United Nations Human and Environmental Association. Noise pollution is often neglected in life because it is “invisible”, prompting it to become an invisible life killer. The kitchen has always been considered the most polluted place in the home. Nowadays, every household is equipped with a range hood, and the pollution of the soot has been largely removed. As everyone knows, just when the hood clears the visible fumes, it brings invisible noise pollution. Noise is an important indicator to measure the performance of the range hood. It refers to the A sound power level measured by the specified method when the range hood is operated at the highest speed and rated frequency. The national standard is not more than 74dB. If it is greater than 74dB, it will affect the health of human beings. Noise pollution firstly causes hearing, and secondly it can induce various diseases such as cardiovascular system, digestive system and nervous system. At the spiritual level, it will cause different levels of interference in working conditions and moods. In the home environment, the volume of more than 50 decibels will become a different level of noise pollution, becoming an invisible enemy of modern families enjoying quality life. The noise caused by the hood is very large, mainly due to the following two factors. The first is the installation problem. If the installation panel, the check valve, the impeller, etc. are improperly installed, the noise of the range hood will increase. Secondly, it is a problem of the exhaust pipe. The smoke exhaust pipe is too long or the phenomenon of "dead bend" will increase the noise of the hood. Therefore, if we want to solve the problem of noise from the hood, we can start from these two aspects. Only by minimizing noise, can we truly enjoy the health and tranquility brought by quality life!

Frequency Converter

These keywords represent critical components and applications within the electrical and industrial sector. Here's how they can be classified:

1. Frequency Converter: A frequency converter is a device that converts the frequency of an alternating current (AC) to match the requirement of a particular electrical device or system. This allows equipment designed for specific frequency to operate in regions where the electrical supply has a different frequency. For example, a frequency converter can be used to allow a device designed for a 60Hz supply to operate in a region with a 50Hz supply.

2. Variable Frequency Drive (VFD): A VFD is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. VFDs have significant applications in industrial systems and machinery, where they allow for precise control of motor speed and torque, leading to increased efficiency and longevity of equipment.

3. Pumps, Fans, Conveyors: These are common applications of motors controlled by VFDs. The variable speed provided by the VFD allows these systems to operate more efficiently and adjust to the specific demands of their task. For instance, a pump's flow can be controlled more accurately, fans can be speed adjusted according to the cooling requirement, and conveyor speed can be precisely managed based on the production line's needs.

4. Phase Motor: A phase motor refers to the type of electric motor, which operates based on the phase of the power supply. The most common types are single-phase motors and three-phase motors. Single-phase motors are usually found in lower power applications like household appliances, while three-phase motors are used in higher power applications, often in industrial settings. These motors can be controlled using VFDs for enhanced performance and efficiency.

These components play significant roles in various industries and are essential for efficient operation in many modern systems. The use of VFDs and phase motors, in particular, has revolutionized the way we control and optimize industrial processes, leading to substantial improvements in energy efficiency and system longevity.
