PM-7 Machine Process Details
Sil Hydraulic Headbox Where many of the important paper properties are
determined.
Press SectionRemoval 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 SectionWater is removed from the paper by evoporationIn dryer roll saturated steam is usedThere are 43 dryer rolls out of which 31 at
predryer 12 at postdryer rolls.
Vacuum RollWater is removed from the paper by Vacuum
pressure.There are 18 vacuum Rolls
SizerThe starch is applied on the both the side of paper
to give properties for printing and writing paper.Steam consumption are achived
Soft Calender RollGive 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” ReelIt provide smooth reeling technique
Winder The winder cut the reel into smaller rolls according
to customer order.

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 LifeRating lifeLoad carrying capacityOperational reliability
• RigidityThe Rigidity is determined by the type, size and
operating clearance of the bearing.
• Friction and Increases in TemperatureFriction is the force resisting the relative motion of
solid surfaces, fluid layers, and material elements.Sliding against each other increases in
temperature
• SpeedThe rate of change of its position
• LubricationImportant for reliable operation, long operating
life, smooth working of bearing and to resist from corrosion.
• Design of Bearing arrangementAs per international standardization (ISO280)Requirement of machine.
