How Do Vacuum Cleaners Work?

Saturday, May 13th, 2017

There are many different types of vacuum cleaners, from many different manufacturers, and despite some looking very futuristic, and others looking very minimal, they all work pretty much the same way.

A vacuum cleaner picks up dirt in a similar way to how a straw works.  Because there’s a difference in pressure at the top of the straw compared to the bottom, the liquid passes up the straw.  Another way to describe it is like the changing of the air pressure over a plane wing so that the plane can fly. 

Cheap Vacuum Bags

Sunday, July 3rd, 2016

In these days of hard economic times, everyone is looking to pinch a penny here or there, and there is often no better way to do this than to take an inventory of what you use on a regular basis and then go buy the cheap version. A little due diligence on your part will enable you to find cheap vacuum bags that are just as good as if not better than the name-brand ones you maybe have been relying on recently.

Something about Vacuum tube

Wednesday, June 24th, 2015

In electronics, a vacuum tube, electron tube (in North America), or thermionic valve (elsewhere, especially in Britain), reduced to simply “tube” or “valve” in everyday parlance, is a device that relies on the flow of electric current through a vacuum. Vacuum tubes may be used for rectification, amplification, switching, or similar processing or creation of electrical signals. Vacuum tubes rely on thermionic emission of electrons from a hot filament or cathode, that then travel through a vacuum toward the anode (commonly called the plate), which is held at a positive voltage relative to the cathode. Additional electrodes interposed between the cathode and anode can alter the current, giving the tube the ability to amplify and switch. recommend directory: 3528 SMD Flexible Strip with Non-waterproof 5 Meter 300 LEDS.
