Maintenance of Machine & Main Functioning Parts of Machine Maintenance of Machine & Main Functioning Parts of Machine Presentation Transcript

  • Presentation Report On Industrial Training “Maintenance of Machine & Main Functioning Part of Machine” By Rohit G. Sorte
  • Covering Area • About Industries • Manufacture of Wood pulps • PM-7 Machine Working Process • Maintenance (Shutdown/Breakdown) • Pumps • Bearing
  • Profile • Bilt is a flagship of the us$4 bn Avantha Group. • India`s largest manufacturer of Writing and Printing Paper. • Bilt is largest exporter of Paper. • Bilt(Ballarpur Industries Limited) name changes to BGPPL(Ballarpur Graphic Paper Production Limited.
  • Bilt Has Six Manufacturing Unit in India 1. Ballarpur, Maharashtra 2. Yamuna Nagar, Haryana 3. Kamalapuram, Andhra Pradesh 4. Bhigwan, Maharashtra 5. Ashti, Maharashtra 6. Gaganpun, Orissa
  • logs •Wood blogs from forest De-barking •Process of removing bark from wood Manufacture of Wood Pulp
  • Chipper & washing •Chipping of wood and washing of wood to remove unwanted material like Sand Refiner Defibration •Separating of cellulose fiber
  • Bleaching •Used for whitening of paper Paper Machine •Pulp is turn into Paper
  • About PM-7 • Capacity of PM7 155000TPA • Deckle at Pope Reel 5.46mts • PM operating speed 1100 mpm • Budgeted of machine 525crs • GSM Range 54-90 gm/meter • Production 519TPD(60GSM, 1100m/min)
  • PM-7 Machine Process Details Sil Hydraulic Headbox  Where many of the important paper properties are determined. Press Section Removal as much water as possible from the paper wet and compresses it. Wet pressing less a significant affect on paper properties(when the paper wet strength is good).
  • Dryer Section Water is removed from the paper by evoporation In dryer roll saturated steam is used There are 43 dryer rolls out of which 31 at predryer 12 at postdryer rolls. Vacuum Roll Water is removed from the paper by Vacuum pressure. There are 18 vacuum Rolls
  • Sizer The starch is applied on the both the side of paper to give properties for printing and writing paper. Steam consumption are achived
  • Soft Calender Roll Give surface properties like gloss, smoothness 2 sidedness monitoring & calliper profile. The machine is equipped with one heated cylinder and one (ACR) Adjustable Crown Roll.
  • “D” Reel It provide smooth reeling technique Winder The winder cut the reel into smaller rolls according to customer order.
  • Maintenance (Shutdown/Breakdown) • Job screening • Scoping • Availability • Planning • Schedule • Execution • Close-out
  • • Job Screening Priority of doing job Risk of doing job • Scoping Replace Repair Patch up Defer work
  • • Availability Availability of material Availability of man power • Planning Job tasks Labor management Cost estimate Safety
  • • Scheduling Time management Availability of material • Execution Work to do • Close-out Inspection of work Completing the job
  • Pumps • Pumps means conversion of mechanical energy to hydraulic energy. • Pumps are used to move Fluid.
  • • Dynamic pressure pumps ( thronging ) Centrifugal Pumps Fluid move from center to outer side
  • • Jet pumps Suction of fluid & rotation and discharge
  • Positive displacement Pumps It is Physical pushing
  • Positive displacement Pumps • Reciprocating Pump • Rotary Pump
  • Reciprocating Pump • Piston Pump • Diaphragm Pump
  • Piston pump  Where Piston is used to give motion to the fluid by crank mechanism
  • Diaphragm Pump
  • Rotary Pump • Gear pumps  A gear pumps which is used as a meshing gears, to pump the fluid by displacement.
  • Screw pump • A pump that raises water by means of helical impellers in the pump casing.
  • Lobe Pump
  • Bearing Basic principal of Bearing • Load Carrying Capacity and Life • Rigidity • Friction and Increases in Temperature • Speed • Lubrication • Design of Bearing arrangement
  • • Load Carrying Capacity and Life Rating life Load carrying capacity Operational reliability • Rigidity The Rigidity is determined by the type, size and operating clearance of the bearing.
  • • Friction and Increases in Temperature Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements. Sliding against each other increases in temperature • Speed The rate of change of its position
  • • Lubrication Important for reliable operation, long operating life, smooth working of bearing and to resist from corrosion. • Design of Bearing arrangement As per international standardization (ISO280) Requirement of machine.
