You too from a closed container, from a dug well, maybe he gets his water from a cistern? If yes, you must have met the float switch. If you don't know, what is it for, stay with us, because today's article is about the operation of the float switch, it will talk about its structure and tasks.
What is a float switch?
The float switch usually controls the operation of the submersible pump, which helps in that, so that we can measure the water in the dugout from a well, or from a closed container. Float switches have several roles and designs, therefore, it can be used for any liquid.
What tasks do you perform??
The main function of the float switch is to, to start the pump between two water levels. By using a float switch, so-called dry running can be avoided, and its use also helps in that, to reach a pre-set amount of water. The float switch can be used to empty and fill the tank, it depends on the setting.
What types are there??
It's quite simple, to water, in addition to float switches that can be used for well water, there are also devices available, which for waste water, for liquids containing solid impurities, can also be used for liquids contaminated with oil. Float switches for pumping special liquids are also available, which can be used for acidic and alkaline solutions.
Structure of the float switch
The outer casing is usually made of polypropylene. This is sealed completely waterproof. Thanks to the material and the seal, the device is completely protected against dust, and more, mint 1 provides continuous operation even at a depth of meters under water -10 °C is 60 °C fokos környezeti hőmérséklet között.
There is a microswitch inside the device, which is switched on by a suitable lever, mechanically, with the help of a ball. The ball is affected by the tilt, i.e. it is, exactly where the float switch is on the water level.
The electrical cables inside are insulated by two materials, neoprene and PVC. The advantage of neoprene over PVC, that while PVC is a more rigid material, while neoprene is more resistant to physical effects, and the expansion coefficient is also better. Neoprene is resistant to chlorine, does not react with the medium, while chlorine dissolves from PVC.
What to consider when choosing?
Be sure to consider before choosing the right float switch, for what purpose we want to use it, and that too, in which liquid we want to use the device. Let's examine it, do we have special needs. There are also pieces available on the market, which are especially suitable for industrial use, they can also be easily used for thicker liquids. It can also happen, that someone is looking for such a float switch, which you want to place in a narrow container. Even this can be solved today, since nowadays the range of float switches is also wider, everyone can find a piece that suits them in terms of size and performance.
These would have been the tasks of the float switch, advantages and principle of operation, if additional articles is also curious about the subject, visit my website again next week, when we are waiting for you and all interested parties with another interesting topic!
