Rotary fan product features:

1, load change, the airflow stability (for example: sewage aeration tank pressure changes, load changes, but little air volume changes over pressure.

2, small volume, big air volume, low noise and save energy (rotary fan adopts the principle of operation of compressed air, although small, but the big air volume, energy saving, mute function is unmatched by other forms of the fan.

3, maintenance is simple, less failure, long life, low speed, small abrasion, long service life.

4, stable running, convenient installation, small model as long as the place is in order when working with vibration is very small, do not need to add vibration control device, convenient installation.

5, excellent material, structure, performance excellence (blower are all made of high quality materials, structure compact, strong and durable, performance is remarkable, the long-term use of fault.

6, with the air chamber, air smooth (all models with air chamber, can prevent the air pulse, smooth perforated.

Working principle of the rotary fan:

HC rotary fan structure is exquisite, the blower pressure range: 0.1 to 0.5 KGF/cm2, flow range: 0.19 to 10.2 m3 / min. Mainly from the following six parts: the motor, transition device, air blower, air chamber, the base of ontology () and fuel tank, drip nozzle. Blower run by cylinder offset in the rotor eccentricity, and between the blades of the rotor slot of volume change in air, compressed, spit out. Using the pressure difference between the blower in operation automatic lubrication to drip nozzle, drop into the cylinder to reduce friction and noise, and can keep the gas inside the cylinder does not return.

Rotary fan air volume and pressure conversion:

Rotary fan air volume Qs refers to breathe in standard state (absolute pressure of 101.325 kPa, temperature 20 ℃, relative humidity 50%), medium for the air inlet flow of rotary fan, conversion for non-standard state flow section.

Rotary fan flow conversion: when the inlet flow with the benchmark status (0 ℃ temperature, absolute pressure of 101.325 kPa) under flow Qn said, need to press the type conversion into the standard after inspiratory flow under the states of Qs, check the performance table (usually does not consider the humidity).
