What is a Roots Blower

You are currently viewing What is a Roots Blower

A roots blower pump 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.

Root blower working principle

The root 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, root blower working principle which prevents a change of pressure.

Why is the rotary lobe blower called a “Root 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.

How does a “Root Blower” operate?

A Root 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 root blower will operate at a controlled output level
to overcome this resistance.

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

The JD VACUUM SERVICE “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.

Roots Blowers Compressors

These Root Blowers compressors are designed in such a way that the same can have vertical or horizontal airflow.
Further, the Roots blower working with its standard accessories is being supplied together compact unit which makes it
very easy to put in. It is also available as a bare machine for replacement. Roots blower working principle pdf.

Roots Blower Pump

These Roots Blowers pumps are tested for performance as per BS-1571 Part II to work out capacity, pressure, and power
consumption. Stringent internal control tests are administered at each stage of production and every unit is given a test
run lasting several hours under increased load.
