Roots Blower

Roots blower

A roots blower compressor is a positive displacement rotary lobe pump that operates by pumping a fluid with a pair of meshing lobes, not unlike a set of stretched timing gears.`

The fluid is then trapped in pockets surrounding the lobes and carried from the intake side to the exhaust.

Why is that the rotary lobe blower called a “Roots Blower”?

The positive rotary lobe blower was designed in the 1850s by the Francis and Philander Roots brothers. it had been later patented in 1860 by the brothers and therefore the Roots name became the name of the planning.

Identification of different names of root blowers

Roots blower is also known by other names like air blower, twin lobe compressor, twin lobe blower, air compressor, industrial blower, agriculture blower, etc…

Roots blower working principle

The roots blower working principle consists of the following: the process starts with air flowing from the inlet port into the element chamber.

The timed rotation of the rotors against the wall of the chamber creates a so-called “airflow direction”. At this point, there is still atmospheric pressure in these chambers.

As soon as the first lobe passes the opening to the pressure side, the system pressure is adjusted. This is called isochoric compression.

The rotors seal each other off to the inside, roots blower working principle which prevents a change of pressure.

How does a “Roots Blower” operate?

A Roots blower operates using the isochoric compression principle, also known as external compression. The pressure increase is achieved by intermittently transporting a gaseous medium (e.g. atmospheric air) into a system.

By forcing the medium from atmospheric conditions into a system with a given resistance (e.g. a water column, distribution network), the relevant pressure increase is achieved.

The roots blower will operate at a controlled output level to overcome this resistance.

What is the JD VACUUM SERVICE “Twin lobe Blower” series composed of?

The JD VACUUM SERVICE “Twin lobe Blower”; called JDVC, is composed of three conjugate lobe-shaped rotors that rotate inside a pre-machined chamber.

The chamber is sealed by the rotating rotors, and the rotors are synchronized by means of a timing 1:1 gear ratio, positioned at the end of the shafts.

all Bearings are positioned externally to the compression chamber with an oil-lubricated system. The driveshafts have labyrinth-style oil seals, so-called because of the labyrinth of grooves that the oil must pass through. The splash guard lubrication system uses a fine mist of oil for lubrication.
