**Pneumatic Conveyor Roots Fan: A Practical Guide from Selection to Maintenance**
Are you also struggling with the efficiency of the pneumatic conveying system? For example, insufficient air volume, high energy consumption, or equipment failure? Don't worry, today we will talk about the "heart" of pneumatic conveying - Roots blower, helping you solve pain points from selection to maintenance in one stop!
---
1 * * Pain point analysis: Why does your Roots blower always "lose its chain"? **
-Unstable air volume: It may be due to inaccurate calculation of actual needs during selection, resulting in fans being "small horses pulling big cars" or "overusing talents".
-* * High noise and strong vibration * *: Improper installation or long-term overload operation can exacerbate bearing and gear wear.
-Soaring energy consumption: Unreasonable pipeline design (such as too many bends), aging seals and air leaks, wasting electricity costs.

2 * * Selection and Avoiding Pits Guide: 3 Steps to Get It Done**
**① Calculate the amount of fresh air and pressure**
-Air volume (m3/min)=material conveying volume x mixing ratio (material to air ratio).
-Pressure (kPa)=Pipeline resistance (horizontal+vertical+elbow loss)+Material suspension pressure.
*Tip *: Reserve 10-15 extra slots to avoid running at full capacity!
**② Identify the type accurately**
-Low pressure type (<50kPa): suitable for short distances and low-density materials such as flour and plastic pellets.
-High pressure type (>50kPa): used for long-distance, high viscosity materials such as cement and mineral powder.
**③ Brand and after-sales service**
-Choose manufacturers with on-site case studies and request performance curve graphs. Don't just rely on sales to deceive you!

3 * * Installation and Maintenance: The Secret to Extending Life**
**Installation points**
-The foundation should be stable: concrete base+shock-absorbing pad to avoid vibration transmission to the pipeline.
-The pipeline can be straight without bending: reduce 90 ° bends and use diagonal tees or flexible hoses for transition.
**Daily maintenance**
-* * Weekly inspection * *: Belt tightness, lubricating oil level (using ISO VG68 gear oil).
-* * Monthly cleaning * *: Blockage of the inlet filter will cause a decrease in air volume!
-* * Abnormal noise warning * *: The gear "clicking" sound may be due to poor alignment, stop the machine immediately for adjustment!

4 * * Advanced Optimization: Power saving and**
-* * Variable frequency drive * *: adjusts the speed according to the conveying capacity, saving more than 30% electricity compared to valve throttling.
-* * Muffler * *: Installing mufflers at the inlet and outlet reduces noise by 20 decibels, making communication in the workshop easier.

**Summary: Roots blower is used well and the conveying system is worry free! Starting with precise matching from selection, installation and maintenance are not lazy, coupled with energy-saving tips, your pneumatic conveying efficiency can be further improved!
