Standard vibration value for water pumps, in mm/s

Thread Content

The standards for vibration levels of water pumps vary depending on the type of pump and its operating speed. Below is a summary based on the information provided: 1. The normal vibration range for low-speed pumps (with rotational speeds below 1500 rpm) is 0.05 mm/s to 0.15 mm/s. 2. For medium-speed pumps (with rotational speeds ranging from 1500 rpm to 3000 rpm), the normal vibration range is 0.15 mm/s to 0.3 mm/s. 3. The normal vibration range for high-speed pumps (with a rotational speed of over 3000 rpm) is 0.3 mm/s to 0.5 mm/s. 4. The vibration value of ordinary water pumps should not exceed 0.2 mm/s. 5. The vibration value of high-speed water pumps should not exceed 0.4 mm/s. 6. The vibration value of long-axis-distance high-flow water pumps should not exceed 0.25 mm/s. 7. The vibration velocity of conventional centrifugal pumps must not exceed 2 mm/s, and the frequency must not exceed 10 Hz. 8. The vibration velocity of pressure boosting pumps shall not exceed 1.8 mm/s, and the frequency shall not exceed 10 Hz. 9. The vibration velocity of the submersible pump shall not exceed 1.5 mm/s, and the frequency shall not exceed 10 Hz. 10. According to the **standards, the vibration level allowed during the operation of the water pump is 0.28 mm/s. These standards provide the range of vibration values for different types of pumps under various operating conditions, which helps to determine whether the pumps are operating properly.
