If the speed of the textile loom is 500 per minute, how to calculate the efficiency formula? 12 hours, 34 shuttles, 66 meters, how efficient is it?

Loom speed = 500 rpm

Actual loom output = 66m/12h = 5.5m/hr.

The weft density data provided by this unit is unclear; Weft density is usually expressed by the number of weft yarns in 10cm. You only gave 34 weft, and it is tentatively set as 1cm, which means the weft density is 340/10cm.

60 times the loom speed per minute

Theoretical output of loom =-.

10× weft density/10cm

60×500

=-= 8.8235 m/h

10×340

Introduce formula:

Actual loom output (m/hour. Taiwan Province)

Loom efficiency =-%.

Theoretical output of loom (m/h). Taiwan Province)

5.5 m/h

= - =62.33 %

8.8235 m/h

That is, the loom running efficiency is 62.33%.

(62.33% is inefficient. )

(If the weft density you provide is 1 inch, then the weft density should be 134/10cm, and the loom efficiency is only 24.57%, which is obviously too low; Therefore, it is considered that weft density is measured by the number of weft yarns in 1cm. )
