I recently purchased a cheap 1200 watt vacuum cleaner. in m-not "Traffic light" for only 1700 rubles. Cheaper, I have never met network dust cleaners with such a pulling force. The power tag in the second photo, turn to the right.
I began to find out why it is so cheap. Disassembled, appreciated. When I got to the engine, I was overcome by doubts. About the declared capacity. Looked at a Chinese site for the sale of all kinds of goods trash, aliexpress and was surprised. Engines with such characteristics cost more than 2,000 rubles. Then I also shared with readers that you can buy a vacuum cleaner just for the sake of the engine. After thinking a little, I decided to purchase a device for measuring power. Wattmeter. He has already arrived and is ready to check on his Chinese brother.
Wattmeter
A device that measures the energy consumption of the device connected to the electrical network. Power is measured in "watts". Also on the display of the wattmeter you can find out the current strength, mains voltage, mains frequency, maximum and minimum power consumption. This device can be configured to calculate energy consumption for a specific period of time. And find out how much money an electrical appliance "eats"
First, you should check the wattmeter itself, for this I use an ordinary 95 W bulb. As shown by the tests of the device, the lamp power is 99 W. Inconsistency with what is written on the lamp and the wattmeter reading, due to the cunning of Ilyich's light bulb manufacturers. By law, it seems that it is forbidden to produce 100 W incandescent lamps. Therefore, we will assume that my Wattmeter has a small error. Within a reasonable.
He signed each photo. For a general understanding of what a wattmeter can measure.
We proceed to change the power of the vacuum cleaner motor. How much good suction power will be on the nozzle depends on this characteristic. We connect the vacuum cleaner to our device... They shod me ...
This is how it happens, instead of 1200 watts, only 750 watts. If the real power was written on the unit itself, then I navryatli bought it. I remember thinking before buying: - "Something rather weak vacuum cleaner, okay buy, for cleaning the car interior" -.
Many who purchased this device were deceived. Or am I the only one so unhappy? And I came across a vacuum cleaner, "by accident", with a weak engine. In order not to be unfounded, I shot a video. Check it out.
Why did it happen that vacuum cleaners with a power of 750 W appeared on the counters of the "Traffic light" mall? instead of 1200 W.? Most likely, one of the first batches of these vacuum cleaners came with normal good 1200W motors. I am sure that suppliers to Russia are checking them for the declared characteristics. And when it came to large parties, the Chinese "brothers" decided to earn extra money. And they installed the power plants cheaper. Thus, they put into their pocket a not feeble difference in the price of components. They even glued nameplates to the engine with more power.
If you are interested in this device, then you can purchase it on aliexpress, with delivery from Russia - wattmeter. The review of the vacuum cleaner was here - link
