ABSTRACT

The fan performance detect system is based on embedded ARM integrated system that detect and analysis the operational status of Fan performance.

CONT…..

It is realizing the fan system monitor each parameter real-time, reduce the traditional fan testing on the field personnel needs, and improve the fan detection accuracy of various parameters.

INTRODUCTION

In the detection of fan performance, the fan flow is an important index of the fan running status.

CONT…..

There are lots of measurement of fan flow methods to choose and the kinds of flow meters are also relatively rich.

For example, rotor flow meter, turbine flow meter, uniform tube flow meter, ultrasonic flow meter, waist wheel flow meter etc.

TYPES OF FAN

Common types: Tubeaxial vaneaxial propeller

CONT…..

Tubeaxial: impeller is inside a tube to guide airflow and improve perf

CONT…..

Vaneaxial: like a tube-axial except vanes either up or downstream of the impeller are used to reduce swirl and improve performance.

CONT…..

Propeller : It is a type of fan that transmit power by converting rotational motion into thrust.

FAN LAWSThe laws only apply to aerodynamically similar

fans at the same point of rating on the performance curve.

Under these conditions, the dimensionless parameters will be constants.

Be careful determine the fan speed change by fan law – you may move to a very different spot on the performance curve, which will invalidate your results.

CONT…..

Law 1 – relates to effect of changing size, speed, or density on volume flow, pressure, and power levelLaw 2 – relates to effect of changing size, pressure, or density on volume flow rate, speed, and powerLaw 3 – shows effect of changing size, volume flow, or density on speed, pressure, and power

FAN CURVESThe fan curves predict the pressure-

flow rate performance of each fan.

CORE MODULES DESIGN

DESIGN OF SYSTEM SOFTWARE

ADVANDAGE

• convenient and quick• Easy to implement• Accurate and correct• Performance will increase

APPLICATION

• Computer system• Ventilation • Blowers• Air craft

CONCULUTION

we must install "measurement integration device of temperature and pressure "on exhaust pipeline.

The test is completed this device can be convenient to take off, and the whole testing engineering convenient and quick.
