American Blowers Specializes In Pump and Blower Repair or rebuilding Offering Both OEM Parts
Pumps are used for raising a liquid – a relatively incompressible fluid – to a higher level of pressure or head; and compressors are used to raise a gas – a compressible fluid – to a higher level of pressure. Blowers are used to move volumes of a gas with moderate increase of pressure; and fans to move large amounts of gas with low increase in pressure.
In blowers lobes or impellers rotate in four positions during operation. The top lobe rotates clockwise and the bottom lobe rotates counter clockwise. As each impeller passes the inlet, a measured quantity of air is trapped between the impeller and the casing. As the shafts continue to rotate this “pocket” of air is transported around the casing to the discharge side of the machine where it is expelled against the pressure prevailing in the discharge line.
In positive displacement/rotary lobe blowers air or gas enters through an expanding section on one side and exits through a decreasing section on the other side. Positive displacement blowers maintain a constant speed and flow regardless of changes in pressure.
Helical screw blower has a main rotor with two lobes. This rotor fits into the flute of a second rotor. The two rotors turn in a helical pattern that is carefully timed so that they do not come in contact with each other. Helical screw blowers typically produce air at higher pressures than rotary lobe blowers do. They also perform more quietly than rotary lobe blowers.
Centrifugal blowers are the most common blowers used in ventilation systems. They’re also used to transport gas and control air pollution. When an air stream passes through this blower’s rotating impellers it increases in both speed and volume. Centrifugal blowers actually change the airflow’s direction as well. If you need a blower with a significantly high pressure and flow; look for a high speed blower. These electrical blowers run via a motor. They have impellers at each side of the shaft to provide double suction.
Regenerative blowers create pressure by displacing air molecules. The impeller spins to draw in and then capture the air between every blade. As the impeller continues to spin it pushes the air forward where it goes back to the bottom of the blade. These types of blowers are good choices if you need to move large air volumes at a low pressure.
The continuous transport of a liquid requires a pump. Pumps are required for the transport of liquid‐and‐gas mixtures and of slurries and suspensions of solids in liquid or gas. Positive displacement pumps work by mechanically trapping a volume of gas and moving it through the pump. Designed in multiple stages on a single drive shaft, the isolated volume is compressed to a smaller volume at a higher pressure, and finally the compressed gas is expelled to either atmosphere or the next pump. Centrifugal pumps transmit energy to fluids through the work of a field of centrifugal forces. Their main purpose is to transfer fluids through an increase in pressure. Centrifugal pumps can have different structures, but their operating principle and fluid dynamic characteristics are always the same. The difference between liquid ring vacuum pumps and rotary vane pump is that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression-chamber seal. Rotary Claw vacuum pumps have two claw-shaped rotors turning in opposite direction inside the housing. Due to the shape of these claw rotors, the air or gas is sucked in,
compressed and discharged. The claw rotors do not come into contact either with each other nor with the cylinder in which they are rotating and are synchronised via a precision gear.
Rotary screw pumps consist of two parallel, screw-shaped rotors, one with a right-hand thread and the other with a left-hand thread. Both screws turn in the compressor housing without friction and at very tight clearances. They are synchronized via a precision gear. The compression housing and the special shape of the screws from the compression chambers.
In the variable pitch models, the gas is compressed at each pitch change and cooled before the next pitch change thus resulting in greater efficiency. In Side Channel Blowers an impeller is mounted directly on the motor shaft for contact-free compression.
