Side Channel Blowers

Posted on by

Side Channel Blowers

The side channel blower or exhauster increases the pressure of the aspirated gas by the creation, in the peripheral toroidal channel, of a series of vortexes caused by the centrifugal thrust of the impeller. While the impeller is rotating, the vanes force the gas forward and, because of the centrifugal thrust, outwards, producing a helical motion. During this motion, the gas is recompressed repeatedly with a consequent linear pressure increase along the length of the channel.

Applications and advantages
Side channel blowers are suitable for all those applications requiring considerably higher pressures than that which can be achieved using centrifugal fans. Side channel exhausters are used in all those applications requiring an operating vacuum higher than the one achievable by a fan, but not as high as to require the use of a vacuum pump. The rotating parts are not in contact with the casing. There is therefore no friction during operation and thus no internal lubrication is necessary. The gas moving through the machine therefore remains uncontaminated and completely oil-free. The other main advantages of using side channel machines are: easy installation;
low noise level;
no vibration and therefore complete dynamic stability;
pulsation free discharge;
minimal maintenance.

Electromagnetic air pump

Electromagnetic air pump

Operating principle
The activated electromagnets put a permanent magnet into oscillation movements. The magnet holder moves now at the same frequency as that of the power supply – normally 50 Hz respectively 60 Hz – back and forth between the electromagnets and sets a diaphragm going on both sides, which then changes the valve box volume. By discharging via the valves, both pressure and vacuum can be realized.

Advantages
Long life expectancy
Motor and pump parts are combined in one single construction. The compact and light construction form and the simple mechanism guarantee a long and reliable period of operation.
High degree of efficiency
The principle of electromagnetic oscillation, which practically has no mechanical friction, minimises power consumption and provides a high degree of efficiency.
Low noise level
The soundproof casing and the muffl er integrated in the tank base reduce operating noise.
Low vibration
Motor and pump parts are separated by a vibration-isolating rubber, so only low vibration consists.
Completely oil-free
The oil-free operation guarantees a dry and unadulterated air flow.
Pulsation-free air flow
Specially formed pump chambers and the muffl er integrated in the tank base provide an air fl ow, which is practically pulsation-free.
Weatherproof
All series with a housing (SLL, EL, JDK) are rainproof and weatherproof. However, they should not be exposed to direct sunlight, rain or snow.
Universal service kits
For each model series service kits are available. They are vacuum-packed in aluminium foil for better and longer life/ storage.

Positive Deplacement Blowers

POSITIVE DISPLACEMENT BLOWERS
AND EXHAUSTERS
Operating principle
MAPRO® Positive Displacement machines consist basically of a pair of Tri-lobe rotors, mounted on parallel shafts, rotating in opposite directions inside a properly shaped casing closed at the ends by side plates.
The two Tri-lobe rotors are synchronized by a pair of timing gears.
As the rotors rotate, air is drawn into the inlet side of the casing, is moved from the inlet to the outlet side by the free volumes between rotors and stator and finally is forced out of the outlet side against the connected system pressure.
The machines, being positive displacement type, do not develop pressure within the casing but the discharge pressure depends only upon the connected system resistance.

Technical and constructional features of the machine body
• Stators, rotors, side plates and covers are totally made of grey cast iron.
The covers of model ML175 are made of aluminum alloy so that to increase the efficiency of the cooling of the lubricating oil;
• shafts are in carbon steel and rotors are shrinked on the shafts;
• the timing gears are helical type with involute profile and made of alloy steel, with hardened and ground teeth;
• sealing of the conveyed gas on the rotor shafts is assured by labyrinth seals and segments;
• bearings and timing gears are lubricated by the oil splashed by disks fitted on the rotor shafts.

Technical and constructional features of the Packages
Standard Packages
• MAPRO® Positive Displacement Blowers are usually supplied complete with discharge silencer integrated in the supporting baseplate and with inlet silencer built-in into the inlet filter;
• the blowers are coupled tothe electric motor via belt drives; thanks to the hinged motor support the belt drive tensioning is automatic;
• the standard packages are complete with pressure relief valve, non-return valve, antivibration base mounts, outlet flexible hose and safety drive guard;
• on request the packages can be supplied fitted with manometer and filter restriction indicator.

Soundproofed Packages

• The standard packages can be supplied complete with acoustic enclosure;
• the package is fixed on the baseplate of the acoustic enclosure; and besides the enclosure is equipped with air extraction fan, manometer andfilter restriction indicator for a quick check of the working conditions of machine;
• on request the soundproofed packages can be supplied fitted with thermometers and temperature and pressure switches. And besides they could be equipped with system for the quick filling and draining of the lubricating oil.
