Controls & Monitoring required for a
gassing machine:
- Speed
Control / tuning – Either with the
help of AC Variable Frequency Drive or Mechanical Variator Pulley is
required to get the required level of weight loss
- Flow
Meter – is essential to control and monitor the flow of gas and air
supplied in the machine
Above this
- Gas supply must be common control and must not have individual control
- In individual drum drive, speed variation between drum may cause variation in gassing. Hence group drum is best
- It
is better to cover the yarn passage by ceramic guides which will prevent
the generation of hairiness and some times it will control the elongation
of yarn
- Winding
tension variation may cause difference in firing hence effective tension device is required
- The
yarn must go throw the centre of the burner and it is better to keep the
bottom and top centering guide as a fixed one (Not a moveable)
- The
adopter bearing must rotate with out any disturbance other it will affect
the take up speed and cause loss variation
- The
cleaning of the burner and guide rollers must be done at proper interval.
Accumulation of scale (evaporated wax content presented in the cotton
yarn) inside the burner will increase the burner temperature and change
the loss %
- Accumulation
of carbon content in the guides will generate further hairs
