45 kW Roots blower usage guide: a thoughtful guide from selection to maintenance
Pain point analysis: Why does your Roots blower always have problems?
Many users often encounter these problems when purchasing and using 45 kW Roots blowers: improper selection leads to low efficiency, non-standard installation causes vibration and noise, untimely maintenance causes equipment damage, high energy consumption increases operating costs Don't worry, today we will solve these troubles one by one!
1. Selection and Avoidance Guide
**Flow and pressure matching: The standard flow range of a 45 kW Roots blower is usually 30-60m3/min, and the pressure range is 9.8-58.8kPa. When making a purchase, it is necessary to choose according to the actual working conditions and avoid "big horse pulling small car" or overloading operation.
**Material selection * *:
-Cast iron shell: economical and suitable for general working conditions
-Stainless steel material: corrosion-resistant, suitable for special environments such as chemical and sewage treatment
**Brand comparison: The brand has a high cost performance ratio. Imported brands (such as) have stable performance but are expensive. It is recommended to choose based on budget and after-sales needs.
2 Key installation steps
**Basic construction * *:
-The thickness of concrete foundation should be ≥ 300mm
-Reserved anchor bolt hole position deviation ≤ 2mm
-The basic maintenance period shall not be less than 7 days
**Alignment adjustment * *:
-Radial deviation of coupling ≤ 0.05mm
-Axial deviation ≤ 0.02mm/m
-Fine tuning using a dial gauge
**Pipeline connection * *:
-Install flexible joints on import and export pipelines
-Pipeline diameter ≥ fan interface diameter
-Avoid sharp 90 ° turns and use a 45 ° diagonal joint
3 Daily Maintenance Calendar
**Daily must do * *:
Check the oil level (keep it at 1/2-2/3 of the viewing window)
Monitor for abnormal noise (stop the machine promptly if there is abnormal noise from bearings or gears)
Record operating parameters (current, pressure, temperature)
**Monthly Focus * *:
Replace lubricating oil (replace after 200 hours of initial operation, and every 2000 hours thereafter)
Check the tension of the belt (preferably with a sag of 10-15mm)
Clean the air filter (if the pressure difference exceeds 5kPa, it must be replaced)
**Annual major maintenance * *:
Disassemble and inspect bearings and gears
Check the rotor clearance (standard value 0.25-0.40mm)
Perform dynamic balance verification (vibration value should be ≤ 4.5mm/s)
4 energy-saving and consumption reducing tips
**Variable frequency transformation * *: Installing a frequency converter can save 20-35% electricity, especially suitable for working conditions with large flow changes.
**Heat recovery and utilization: The exhaust temperature usually reaches 80-100 ℃, and a heat exchanger can be installed to preheat the process water.
**System optimization * *:
-Shorten the length of the pipeline (for every 1 meter reduction in pipeline, the resistance decreases by approximately 150Pa)
-Expand the pipe diameter (flow rate controlled at 10-15m/s)
-Regularly clean the accumulated dust in the pipeline (3mm thick dust accumulation will increase resistance by 15%)
Remember: a properly maintained 45 kW Roots blower can have a service life of 10-15 years, while a poorly maintained one may be scrapped in 3-5 years. Spending a small amount of money on maintenance and saving a lot of money on repairing equipment, this account is worth it no matter how you calculate it!
