GB3216-89 Test methods for centrifugal pumps, mixed flow pumps, axial flow pumps and vortex pumps

The standard for testing centrifugal pumps, mixed-flow pumps, axial-flow pumps, and turbine pumps (GB3216-89) was released in 1989 by the People’s Republic of China and applies to the testing of these types of pumps in China. This article is an overview of the requirements of the standard and how they should be applied in practice.

1. General Principle

The general principle of the standard is to test and measure the performance characteristics of centrifugal pumps, mixed-flow pumps, axial-flow pumps, and turbine pumps. The tests should be conducted in accordance with the standard in order to accurately assess the performance of the pump.

2. Test Types

The types of tests required are generally similar regardless of the type of pump being tested. The tests include flow rate, head, efficiency, cavitation, and noise level. The tests must be conducted at multiple points, covering different speeds, and with different operating parameters such as pressure and temperature.

3. Equipment

The equipment needed to conduct the tests is standard laboratory equipment, including a flow measurement system, pressure measurement system, pump motor, power monitoring system, torque transducer, and pump tester. If the pump being tested is an axial-flow or turbine pump, then a power transducer must also be used.

4. Test Results

The results of the tests should be reported in a format that is easy to understand, including details such as the flow rate, head, efficiency, cavitation, and noise level. The results should also be compared to the manufacturer’s specifications or standards for centrifugal pumps, mixed-flow pumps, axial-flow pumps, and turbine pumps.

5. Conclusions

The GB3216-89 standard provides a method for testing centrifugal pumps, mixed-flow pumps, axial-flow pumps, and turbine pumps in China. It outlines the tests required, the equipment needed, and the reporting format. By following this standard, it is possible to accurately assess the performance of these types of pumps and compare them to the manufacturer’s specifications or standards.
