Complete guide for purchasing and using 7.5kw Roots blower

Common pain point analysis
Many friends often encounter these problems when purchasing and using 7.5kw Roots blowers: improper selection leads to low efficiency, excessive noise affects the working environment, untimely maintenance causes equipment damage, and high energy consumption increases operating costs These issues not only affect production efficiency, but may also bring additional economic losses. Today we will talk about how to avoid these troubles.
Correct selection is key
The 7.5kw Roots blower is suitable for various scenarios such as small and medium-sized sewage treatment, pneumatic conveying, aquaculture, etc. When selecting, it is necessary to consider:
-Air volume requirement: Calculate the required air volume based on actual process requirements, leaving a margin of 10-15
-* * Pressure Range * *: The 7.5kw model is typically suitable for pressure requirements of 0.1-0.5kgf/cm2
-* * Medium characteristics * *: Transport clean air or dusty gas? This will affect the choice of sealing method
2 Installation precautions
Improper installation is one of the main causes of fan failure:
-* * Stable foundation * *: The thickness of the concrete foundation should be ≥ 300mm, and space should be reserved for the installation of shock absorbers
-* * Pipeline connection * *: Use flexible joints to reduce vibration transmission and avoid hard connections
-Ventilation and heat dissipation: Ensure that the computer room has sufficient ventilation and the ambient temperature does not exceed 40 ℃
3 daily maintenance points
Regular maintenance can significantly extend the lifespan of the machine:
-Lubrication Management: Replace gear oil every 2000 hours and check the oil level weekly
-Belt Adjustment: Check the tightness of the belt every month to avoid over tightening or over loosening
-* * Filter Cleaning * *: Clean or replace the air filter every 500 hours
-* * Abnormal monitoring * *: Pay attention to abnormal phenomena such as abnormal noise and increased vibration, and promptly investigate and troubleshoot them
4 energy-saving and consumption reducing techniques
The 7.5kw motor has great energy-saving potential for long-term operation:
-Variable frequency control: Adjust the speed according to actual needs, which can save 20-40% electricity
-Pipeline optimization: Reduce the number of bends and lower system resistance
-* * Waste heat utilization * *: High temperature exhaust can be used for winter workshop heating
-* * Regular maintenance * *: Keep the equipment in operation
5 Common Troubleshooting Methods
Don't panic when encountering problems, first self check these aspects:
-Insufficient air volume: Check if the filter is clogged and if the pipeline is leaking
-Abnormal noise: It may be due to bearing damage or poor gear meshing
-Motor overheating: Check if the voltage is stable and if the heat dissipation is good
-Excessive vibration: Check if the anchor bolts are loose and if the rotor has accumulated dust
Remember, choosing a 7.5kw Roots blower is not the end point, but the starting point of equipment lifecycle management. Choosing a reputable manufacturer, installing and using it correctly, and maintaining it regularly are essential to ensure the long-term operation of this' industrial lung 'and safeguard your production.
