What You Need to Know About Vacuum Pumps
Vacuum pumps are among the few inventions that predominantly feature in our everyday life but very few understand what an important role they play. People rarely acknowledge their importance in their daily to day lives. That said, indeed for us to understand what a it is, we need to learn its history and its subsequent metamorphism. This can be sub-divided into:
Vacuum Pump History
Dating back to 1206, an Arabic engineer had invented a suction pump that set the foundation of the modern vacuum pump. And by the 15th century the sunction pump concept was widely in development in the form of a six-cylinder monobolic Pump that could generate partial vacuum through a series of weights. After that technology and innovation picked up.
Otto von Guericke is credited with designing the first original vacuum pump dated back in 1954. This equipment was able to create a vacuum by pulling gas molecules from sealed area. He conceptualized an experiment to demonstrate that if air was removed from a cylinder (whole) then there was no amount of energy that could separate the two halves of the cylinder. As a whole he was able to convince engineers and further experimentations were carried out till another engineer by the name Heinrich Geissler created a mercury displacement pump that proved more effective than Otto Von’s innovation.
A couple of few hundred years down vacuum pumps have become a norm and are advanced to handle every sort of gas, liquid removal. They are virtually being used in most manufacturing industries.
Types of vacuum Pumps
There are many types of vacuum pumps available today that meet the unique needs of the different industries. Below are some of them:
Positive displacement - They are primarily used to create low vacuums.It is inflate the cavity and allow gases to move out of the sealed container, then block the cavity and exhaust it to the atmosphere or environment.
Liquid ring -Pretty much every industry utilizes the different and diverse vacuum technologies currently found in the market. Vacuum systems are precisely used for extraction of gas, vapor, water, moisture from a sealed space.
Rotary vane - They have blades (vanes)T that support the impeller which spins insider the chamber. Used for pumping fresh non-corrosive gasses.
Molecular or momentum transfer - These pumps help accelerate the transmission of gas molecules from the vacuum side going to the exhaust side.
Entrapment -Just like the names suggests these equipments are used to trap gases in solid state.
Information you need to know and consider when purchasing Vacuum pumps.
Cost – Consider the cost of the machine and also look for the best retailer to sell you the same durable machine for a less cost.
Use - Liquid machine have different purposes and it is imperative to know which best suits your type of industry.
Efficiency -This should also be a priority when buying a vacuum machine.
Guarantee – Buying equipment worth thousands of dollars needs to be backed with a warrant and comprehensive assurance that incase of mishap; you can be reimbursed or replaced.
