Test method of air dynamic performance of GB1230-05 fans
1. Introduction
GB1230-05 fans are used to improve the air quality in the indoor environment by providing the air movement, circulation and ventilation. The GB1230-05 fans are widely used in industrial, commercial, agricultural and residential applications. Test method of air dynamic performance of the GB1230-05 fans is essential in order to ensure the quality of the product. This test method is used to evaluate the performance and ratings of the fan in order to measure the airflow rate, power consumed and efficiency of the fan. The following discusses the methodologies and processes involved in the test method of air dynamic performance of GB1230-05 fans.
2. Test Methodologies and Processes
A. Test Instrument
In order to carry out the test method of air dynamic performance of the GB1230-05 fans, a test instrument is required. A flow transmitter is used to measure the airflow rate (air volume per unit time). The fan is connected to the intake side of the flow transmitter and the exhaust side is connected to the atmosphere. The flowmeter should be calibrated before testing and installed in appropriate places.
B. Measured Parameters
The following parameters are measured in order to characterize the air dynamic performance of the fans:
• Airflow rate: This is the amount of air (in cubic feet per minute/hour) flowing through an infinite number of leak-free spaces at a given pressure in a given area. It is usually expressed in cfm (cubic feet per minute).
• Power consumed: This is the electrical power consumed by the fan motor in order to drive the fan.
• Efficiency: This the ratio of the airflow rate and the power consumed by the fan. It is usually expressed as a percentage.
C. Test Procedures
The test procedure of the air dynamic performance of the GB1230-05 fans involves the following steps:
• Place the fan in an airtight room and connect its intake side to a flow transmitter.
• Measure and record the airflow rate at different pressurizations.
• Connect the fan to a power supply and measure the power consumed by the fan.
• Calculate the efficiency of the fan by dividing the airflow rate by the power consumed.
• Repeat the above steps for multiple speeds and pressurizations.
3. Conclusion
The test method of air dynamic performance of the GB1230-05 fans is essential in order to ensure the quality of the product. It is used to evaluate the performance and ratings of the fan in order to measure the airflow rate, power consumed and efficiency of the fan. This test method involves the use of test instruments, measured parameters, and test procedures to accurately measure the air dynamic performance of the GB1230-05 fans.
