Blowers

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

Packages

A motor blower package is the ‘air mover’ in a pneumatic conveying system. In a pressure system, atmospheric air is filtered before entering the system, then that air is powerfully blown through pipes. … In negative pressure systems, the air is filtered from the system side and exhausts to atmosphere.

Accessories

Pressure Safety Relief Valve

Clogging of the pipeline, over feeding of bulk solid in pneumatic conveying system, incorrect adjustment of valves, high back pressures are some of the reasons that cause extra force on blowers. Safety relief valve protects the blower from over-pressurization. If the air or gas pressure in the pipeline exceeds the process limits, the valve opens and allows air to bleed off.

Vacuum Safety Relief ValveSimilar to pressure relief valves, vacuum safety relief valves protect the blower from under-pressurization. If the air or gas vacuum level in the pipeline exceeds the process limits, the valve opens and allows air to enter the pipeline and reach the desired vacuum level.

 

Silencer

The two lobes of positive displacement blowers cause continuous pressure fluctuation at each turn. This fluctuation causes high levels of noise. Blower inlet / suction silencers and blower outlet /discharge silencers are used to decrease the amount of this fluctuation and reduce the noise.

 

Inlet Filter

Dust built up and small particles will cause damage on blower impellers. Inlet filters of roots blower are critical components to maintain long service life. Depending on environment and process conditions, different types of blower inlet filters are used.

Enclosures

Sound Enclosure / Acoustic Enclosure

To decrease the noise coming from blower packages, sound enclosures are used. Any mechanical noise coming from blower, motor , mechanical coupling etc. are eliminated by these acoustic enclosures.

Advantages of Acoustic Enclosures

Low noise level Easy maintenance and easy access to internal equipment Efficient air circulation and cooling Optional fan for extra cooling and ventilation Optional built in control panel Robust construction suitable for outdoor operation and harsh environment

Inlet Air Cooler

Especially in pneumatic conveying of food materials such as sugar, plastic pellets etc, physical and chemical properties of conveyed material are negatively affected from elevated air temperatures. Air cooling systems are used in such kind of applications where the process air temperature is to be kept below a determined level.
