The working face of the suction cup is made of elastic, flexible material and has a curved surface. [3] When the center of the suction cup is pressed against a flat, non-porous surface, the volume of the space between the suction cup and the flat surface is reduced, which causes the air or water between the cup and the surface to be expelled past the rim of the circular cup.

Suction is the vertical distance between the fluid to be pumped and the centre of the pump, while lift is the vertical distance between the pump and the delivery point. [4] The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [ 5 ]
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. [1] (An electrically-operated pump for this purpose would usually be called a vacuum pump.)

It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
The self-sealing suction cup is a suction cup that exerts a suction force only when it is in physical contact with an object. Unlike most other suction cups, it does not exert any suction force when it is not in contact with an object. [1] Its grasping ability is achieved entirely through passive means without the use of sensors, valves, or ...
The suction excavator uses suction fans for the airflow to suck up the material that is then transported into the holding tank. Hydro excavation , a type of suction excavator using high-pressure water jets , is sometimes referred to as daylighting , as the underground utilities are exposed to daylight during the process.

The short tube and hose barb effectively act as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to the flask. The other end of the hose can be connected to source of vacuum such as an aspirator, vacuum pump, or house vacuum. Preferably this is done through a trap (see below), which is ...
