The vibration range of Roots blowers usually varies depending on their power and usage environment. Here are some common ranges of vibration values for Roots blowers:
1、 Vibration value range classified by power
1. Low power fan: For fans with a power below 4kW, their vibration speed should be below 5mm/s. However, please note that there is information indicating that the normal vibration range of Roots blowers is generally 0.1mm/s to 0.3mm/s, and the out of limit vibration value is generally 0.5mm/s.
2. Medium power fan: For fans with a power between 4kW and 157kW, there may be a range of vibration speed standards, such as 5mm/s to 7mm/s (this value may vary depending on the specific manufacturer and application scenario, and is not a strict standard range, for reference only). But it is also necessary to refer to the normal vibration range of 0.1mm/s to 0.3mm/s and the over limit value of 0.5mm/s mentioned above.
3. High power fans: For fans with higher power (such as exceeding 157kW), the vibration speed limit may be more relaxed, but the specific value needs to be determined according to the manufacturer's regulations and actual application scenarios. Similarly, the standards for normal vibration range and excessive vibration should be followed.
2、 ISO standard vibration value range
According to ISO 10816-3 standard, the vibration speed limit of Roots blower should be below 2.8mm/s (measured on the vertical and horizontal plane of the blower). This is a universal vibration standard that is applicable to various types of mechanical equipment.
3、 Range of vibration values in practical applications
In practical applications, the vibration value of Roots blowers may be affected by various factors, such as installation environment, load conditions, operating time, etc. Therefore, the specific range of vibration values may need to be evaluated and monitored based on the actual situation.
4、 Vibration value detection and monitoring
To ensure the stable operation of the Roots blower, regular vibration value detection and monitoring are required. This usually requires the use of professional vibration sensors and data acquisition equipment to convert vibration signals into electrical signals for collection, analysis, and processing. By monitoring the trend of vibration values, potential faults and problems can be detected in a timely manner, and corresponding measures can be taken to deal with them.
In summary, the vibration range of Roots blower is a relatively complex parameter that needs to be evaluated and determined based on specific circumstances. However, in any case, the manufacturer's regulations and general vibration standards should be followed to ensure the stable operation of the fan.
