Need

• Usual In Rural Areas Where Power Supply Is Not
  Sufficient
• Drawbacks in pump (Diesel Engine)
  
• Makes Noise Pollution
• Makes Air Pollution
• Require Costly Fuel
• Pumps (Electricity)
• Fail In Case Of Power Shortage
• Typical Circuit

Introduction

• Water Lifting Is Done By Using Manual Power From
  One Level To Another
• In Vertical Direction Closed Path Such As Pipe In
  Which a P.d Is Created
• Power Source Is Manual Work As We Aimed At The
  Need Of Rural Areas And Cheap Labour

Construction

• Mild Steel Rod Axel (25mm dia.)
• Larger Sprocket (87 teeth263.8mm dia)
• Smaller Sprocket (21 teeth68mm dia)
• Impeller (1/2 H.p)
• Rolling Contact Bearings (25mm bearing dia
  Single row deep groove ball bearing-light
  Medium series)

Mechanism

• It Consists Of Impeller Mounted On Shaft ,Driven
  By a CHAIN MECHANISM (pinion wheel)
• By Rotating The Wheel Manually Selecting The
  Proper V.R. ,Attain a Speed Of 720 rpm which Can
  Lift Water
• Impeller Is Driven By Chain Converts K.E. In Pr.
  Energy Water Is Lifted

Bush Roller Chain

• It Consists Of Outer (Pin link) Plates , Inner
  (Roller Link) Plates , Pins , Bushes Rollers
• Pin Passes Through Bush Which Is Screwed In Holes
  Of Roller Between The 2 Sides Of The Chain
• Rollers Are Free Two Rotate On Bush Which Protect
  The Sprocket Wheel Teeth Against Wear
• Materials Of Bushes , Pins , Rollers Is Alloy
  Steel
• This Chain Is Strong Simple In Construction

Ball Bearing

• Introduction
• In rolling contact bearing surface is rolling
  instead of sliding as in sliding contact bearing.
• In ordinary sliding bearing has a high
  coefficient of friction.
• It is an outstanding advantage of a rolling
  contact bearing over a sliding bearing that it
  has a low starting friction.
• So that these are called antifrictional bearing.

19
Advantages

• Low starting and running friction except at very
  high speeds.
• Ability to withstand momentary shock loads .
• Accuracy of shaft alignment.
• Low cost of maintenance as no lubrication is
  required .
• Small overall dimensions.
• Reliability of service.

20
Types of rolling contact bearing

• Ball bearings
• The ball bearing consists of an inner race which
  is mounted on the shaft or journal and an outer
  race which is carried by the housing or casing.
• In between the inner and outer race there are
  balls or rollers.
• The ball bearing are used for light loads and the
  roller bearing are used for heavier loads.

21
Types of radial ball bearings

• Single row deep groove bearing
• Filling notch bearing
• Angular contact bearing
• Double row bearing
• Self aligning bearing

22
Single row deep groove bearing

• The deep groove ball bearing are used due to
  their high load carrying capacity and suitability
  for high running speeds.
• The load carrying capacity of a ball bearing is
  related to the size and number of the balls.
