FAQ’s (Frequently Asked Questions):
- How do you decide Spindle Replacements ?
Decision for replacing spindles is based on various factors like speeds, load, mill conditions, maintenance, lubrication and of correct lubricating oils. But in general, the following signs indicate replacements:
(a) Life of spindle used
(b) Lubricating oil blackening or consumption increases
(c) Increase in power consumption
(d) Increase in yarn hairiness
(e) Wear out of bearings and high vibrations
- How do you decide correct spindle model choice?
To assist you in making the correct spindle model choice, the following factors have to be considered:
(a) Spinning speeds presently being run
(b) Spinning speeds considered to be run
(c) K-Factor (Load Factor)
We can recommend you the correct spindle model once you inform
- Spinning speeds
- Lift of spindle
- Ring diameter
- Yarn count to be spun
- How do I handle ENS Spindles when it is received at mills?
(a) Spindles when received at mills or department, boxes should be handled and moved with care.
(b) Do not throw or stock the boxes one over the other.
(c) Open boxes carefully.
(d) Spindles when removed from the plastic covers should be stacked carefully.
- How do I prepare ENS Spindle for Installation on Ring Frame?
For Bolster (Lower Part)
(a) Do not remove caps of insert bearing to prevent dust, fluff from entering insert bearing.
(b) Clean and wipe dry external housing of Bolster from anti rust oil applied at ENS factory, by soft muslin cloth.
(c) Install on spindle rail and tighten lightly using correct spanner size.
For Upper Running Part
(a) Take out from plastic cover and keep vertical on suitable rack
(b) Clean upper part complete of all anti rust oil applied at ENS factory, by soft muslin cloth.
- How do I Install ENS Spindle?
(a) Remove the cap from the bolster which is tightened lightly on the spindle rail
(b) Flush and Clean bolster completely to remove any foreign matter using our Spi- ra-clean oiling and cleaning device.
(c) Fill exact height of oil as per Insert bearing level required using Spi- ra-clean (for height suggestions refer to our instruction / maintenance manual) using correct oil level gauge as supplied by ENS SPINDLE.
(d)Ensure neck bearing is always lubricated.
(e)Avoid keeping bolster open too long. Insert the upper part inside ensuring that the bottom blade is completely clean from any foreign matter.
(f) Spindle gauging / Ring Centering to be done precisely to ensure spindle is vertical with correct center.
(g) Tighten the bolster completely to spindle rail – ensure tightening torque not to exceed 500 Kg-F-cm.
- Is Running in Required for ENS SPINDLE?
We do recommend initial running in as this ensures all running parts get smoother, which leads to a better life of the spindle. Running In procedures are explained in our instruction/maintenance manual.
- What is the recommendation for oil change and how to do it?
ENS SPINDLE recommends an oil change generally after 6 months – but this can vary as per spinning conditions and spindle bearing used. Customers are strongly advised to keep check at random frequency to ensure oil quality has not detoriated and most importantly oil height is not gone lower than recommended height.
ENS SPINDLE recommends Spi- ra-clean oiling and cleaning device to ensure perfect oiling and cleaning using separate devices for cleaning and oiling (not a single device) and ensures filling by height (not volume).
- How to choose correct Ring Bobbin for ENS new spindles?
(a) Ring Bobbin is extremely crucial to perfect running of spindle.
(b)Ring Bobbins are to be used as per correct ISO Specification to suit the spindle taper and dimensions.
(c) Clearance between Bobbin and Spindle at DUI should be 0.15 mm (Ring Frame / Bobbin Maker specification to be followed)
(d) Bobbin Inner Diameter should be such so as to enter the spindle smoothly at a load of 700 gms to 1000 gms. Taper to be decided by bobbin maker as per spindle drawing.
(e) Overhang of Bobbin over spindle top should not exceed 20 mm.
- Is Spindle Brake needed to stop the spindle or can the Spindle be stopped by hand?
Never stop the running spindle by hand, this can cause extreme injury to the operator and / or can damage to the spindle or bend the upper running part of the spindle.
It is strongly advised to use spindle brakes, either knee brake or finger brake.
