Why Lobe Blower Needs Acoustic Enclosure?

The acoustic enclosure for lobe blower has two functions: one is is to control the noise level of installation and another to protect the blower and its instrumentation from dust/ rain/wind in outdoor installations, As you are aware, a blower may produce a loud noise during its operation. In case of some installations, especially in environment compliant projects, there is a strict limitation in noise level, commonly restricted to under 85db(A). Where there is a requirement for large displacement volumes,…

Why Lobe Blowers Produce Vibration?

There are several reasons for lobe blowers to produce vibration , even small problem may cause vibration. Although vibrations may not affect the operating parameters of the blower initially, it is imperative to resolve this at the earliest. Here are some of the reasons/ causes of Vibrations: The foundation bolts get loose, it may cause vibration in vertical direction. The couplings don’t cooperate well with each other. (for roots blower having direct coupled drive) The concrete base of the blower or…

Blowers for Mining Industry

Roots Blowers are used in copper, nickel, gold, and diamond mines to name only a few. Principal applications: Pneumatic conveying of dry bulk materials. Air supply for oxidation processes waste water treatment / effluent treatment plants Corrosive Gas Boosting Pneumatic conveying of dry bulk materials: Pneumatic Conveying is a widely adopted means of transporting dry bulk material either by Vacuum or by Pressure of Air. Depending on the material to be conveyed, The air stream with specific velocity will carry…

Why one should insist for Continuous Process system over the kettle?

Let us see what happens in case of batch system. Typical step Pharma industry: Product concentration, after reaction or washings, to evaporate solvent used in the process. Conventional system used: Reaction kettle under vacuum to evaporate the solvent. Batch time: 5 hrs to 20 hrs. [The product gets heated unnecessarily for so many hours] Heating media used: Steam where possible or Hot water if product is much heat sensitive. [Hot water is poor heat transfer media, hence requires more heating…

Mechanical Vapour Re-Compression System

There is a law in Physics which states that no one can create or destroy energy. You can only convert one form of energy into another. Mechanical vapour recompression system is one such energy recovery process. Usually, you find substantial wastage of energy in industries. One of the prime examples is the wastage of steam through evaporation. Steam has tremendous power. James Watt realised the potential of steam to invent the steam engine. Therefore, wastage of steam is a criminal…
