In this article, we'll explain how wireless mesh networks work, how they increase network access for a wide variety of industries, and how they might make our dream of a seamlessly connected world come true.
A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. (An electrically-operated pump for this purpose would usually be called a vacuum pump .).esoldering braid, also known as desoldering wick or solder wick, is finely braided 18 to 42 AWG copper wire coated with rosin flux, usually supplied on a roll. The end of a length of braid is placed over the soldered connections of a component being removed.
An example of a non-positive pump is a centrifugal pump. This type of pump will not pump gases and therefore requires a primer. Ejector Pumps These types of pumps do not use either mechanical pistons or plungers to increase or decrease the pressure but use a fast moving jet of liquid or gas to do the same job. This jet is called a propellant. The ejector pump uses a venture effect within the throat of the pump. At the throat an area of low pressure is created by the fast moving propellant, any movement outside this area being at a higher pressure will flow into the pump. This fluid and the propellant are discharged at the outlet.
