GB 10178-88 Site Test for Fans
A site test of a fan should be conducted in order to ensure that all components of the fan, such as its motor, drive, impeller, and housing are all operating correctly. This test will allow for easy troubleshooting of any issues that may arise. The following outlines the criteria and procedures for conducting this test.
1. Test Setup
The first step of setting up a site test of a fan involves deciding what type of fan will be tested. Typically, centrifugal, axial-flow, or mixed-flow fans are used, and the area with the fan should be monitored for the duration of the test. The area must have adequate ventilation and the fan must be securely mounted in place.
2. Test Instruments
To conduct a successful site test of a fan, the following test instruments and devices should be used:
a. Flowmeters: These should be used to measure the volumetric flow rate of the fan and the associated pressure, temperature, and humidity conditions in the test area. This will identify any potential problems with the fan’s performance.
b. Vibration Monitors: These should be used to check for any excessive vibrations due to the fan’s operation.
c. Voltage meters: These should be used to measure the voltage at various points, such as the motor, fan, and nearby components. This will help identify any problems with the fan’s electrical supply.
3. Test Procedures
Once the test instruments and devices have been selected, the test procedures should be followed in order to assess the fan’s performance.
a. Flow Test: This test will measure the volumetric flow rate at various air flow points near the fan. Measurements should be taken in order to identify any issues with the fan’s airflow.
b. Static Pressure Test: This test will measure the static pressure in the area of the fan. The measurements should be taken in order to identify any issues with the fan’s performance.
c. Power Consumption Test: This test will measure the power consumed by the fan. The measurements should be taken in order to identify any issues with the fan’s performance.
d. Vibration Test: This test will measure the vibration levels at various points in the fan’s operation. The measurements should be taken in order to identify any issues with excessive vibrations.
e. Electrical Test: This test will measure the electrical current and voltage at various locations. The measurements should be taken in order to identify any issues with the fan’s electrical supply.
4. Test Results
Once the site test of the fan has been conducted, the results should be recorded and compared to the established standards set for the fan. Any discrepancies should be identified and addressed in order to ensure that the fan is operating correctly.
Conclusion
The site test of a fan is an important step in ensuring that the fan is operating optimally. The proper test instruments and procedures should be followed in order to identify any potential issues with the fan. The results should be compared to the established standards set for the fan, and any discrepancies should be addressed.
