What is a water aspirator vacuum?

A traditional way to produce vacuum in labs is the water-jet aspirator. A simple device, it attaches to the sink faucet and produces vacuum using Venturi effect principles when the cold water rushes through. Each aspirator requires water rushing through at close to 2 gallons per minute (GPM) to produce vacuum.

How does an aspirator work?

A water aspirator works when water from the tap is forced at a high velocity through a small nozzle. At the smallest part of the nozzle, a vacuum is created. A tube attaches to this portion and the vacuum draws fluid up through that tube. Also, the water needed to run a single water aspirator is 2 gallons per minute.

What is the purpose of a water aspirator?

An aspirator is basically a narrowing tube that hooks up to a hard-spraying water tap and has a sidearm fitting. The accelerating blast of water pulls the air in the tube along with it as it goes, creating a useful vacuum.

How do I keep water out of my vacuum pump?

Hot Pump: A hot pump handles condensables, such as water, by keeping them in the vapor phase. Elevating the oil temperature above the boiling point of the condensable, up to a maximum of 230ºF, can prevent condensing by pumping it through the pump and out the exhaust like any other gas.

What is the function of a water aspirator?

An aspirator, also called an ejector or filter pump, is a device that produces vacuum by means of the Venturi effect. In an aspirator, fluid (liquid or gaseous) flows through a tube which then narrows. When the tube narrows, the fluid’s speed increases, and because of the Venturi effect, its pressure decreases. Vacuum is taken from this point.

How does water aspirator pump works?

The water aspirator pump is essentially a pipe with a narrowing in it. As water flows through that narrowing, it speeds up and its pressure drops-it’s exchanging its pressure energy for kinetic energy. A tiny opening in the side of the narrowing allows water or air to enter the high-speed flow.
