A frequency converter – or variable frequency drive (VFD) – is an electric device that converts a current with one frequency to a current with another frequency. The voltage is normally the same before and after frequency conversion. Frequency converters are normally used for speed regulation of motors used to drive pumps and fans.
A frequency converter is an electric device that converts a current with one frequency to a current with another frequency. The voltage is normally the same before and after frequency conversion. Frequency converters are normally used for speed regulation of motors used to drive pumps and fans.
The following example shows how this works:
A fan is provided with a current of 400 VAC, 50 Hz. At this frequency (50 Hz), the fan can run at a certain speed. To get the fan to run faster, a frequency converter is used to increase the frequency to (for example) 70 Hz. Alternatively, the frequency can be converted to 40 Hz if the fan is to run slower.
You do not want to plug equipment into the wrong power source or you run the risk of allowing the smoke to escape from your equipment. And the smoke is like “a genie in a bottle”, once it escapes from the electronic device, you cannot put it back in……Larger and 3 phase equipment cannot operate on the wrong frequency as the incorrect frequency can cause damage or premature wear on the equipment.
Therefore, How to distinguish a real frequency converter applying on car wash machine that will be a principal purpose.
Actually, almost merchant allege that they have a converter and apply on the car wash machine. But it is not a real frequency converter which can change the voltage and moving speed of car wash machine. Usually, it is a 0.4 small motor applying on the moving body, and it can not set up various models which are Hi&low pressure of spraying water and Hi&low speed of fans. What’s worse, if it is not a frequency converter, when machine start to operation, the instant current is 6-7 times than general current, it will easy to cause circus damaged and electrical wasted.
CBK car wash machine adopts 18.5kw frequency converter technology to drive, and due to High&Low pressure of water spraying and High&Low speed of fans, the electricity consumption will be saved by more than 15%, which means owner can set up any process that he would like to. Therefore, CBK car wash machine can reduce the need for maintenance and the costs that come with it.
Typically,anything with a motor in it will need a frequency converter, and CBK car wash machine can do that.
