FIRE HYDRALICS AND FIRE LOSS CONTROL

1. FIRE HYDRALICS AND FIRE LOSS
CONTROL

2. LESSON 1 PUMP
INTRODUCTION
PUMP
BASIC REQUIREMENT OF PUMP:
a) RELIABLE
b) PORTABLE
c) SUCTION
d) SUBJECTING WATER TO PRESSURE
e) DELIVERY

3. MAIN PARTS OF PUMP:
a) GENERATOR PART
b) SHAFT
c) PUMP ASSEMBLY
TYPES OF PUMPS:
a) DISPLACEMENT PUMP
i. RECIPROCATING PUMP
ii. DIAPHRAGM PUMP’
THE RECIPROCATING PUMP ARE FURTHUR CLASSIFIED AS:
i. FORCE PUMP
ii. LIFT PUMP
iii. BUCKET AND PLUNGER PUMP
iv. ROTARY PUMP

4. B. CENTRIFUGAL PUMP
i. CONVENTIONAL CENTRIFUGAL PUMP
ii. SELF PRIMING CENTRIFUGAL PUMP
iii. AIR OPERATED PUMP
DISPLACEMENT PUMP
RECIPROCATING PUMP
DIAPHRAGM PUMP
CENTRIFUGAL PUMP
SELF PRIMING PUMP
SUBMERSIBLE PUMP
AIR LIFT PUMP
VANE TYPE PUMP

5. BEFORE STARTING PUMP: THE FOLLOWING POINTS ARE TO BE ENSURED
BEFORE STARTING THE PUMP
a) PUMP IS TO BE KEPT CLOSE TO THE WATER ON STRONG BASE.
b) CHECK FOR FUEL AND OIL LEVEL IN CASE OF ENGINE DRIVEN AND
CORRECT ELECTRIC SUPPLY FOR MOTOR DRIVEN
c) KINKS AND BENDS IN HOSE ARE TO BE REMOVED
d) STRAINER SHOUYLD SUBMERGE IN WATER PROPERLY
e) PRIMING IS TO BE DONE IF REQUIRED
f) CHECK AND LOOK AT GAUGES
g) START THE PUMP AND OBSERVE FOR ABNORMAL SOUND IF ANY

6. REASONS FOR PRIMING FAILURE
a) DEFECTIVE GLAND PACKING
b) CHOCKED STRAINER
c) DEFECT IN PUMP CASING
d) STRAINER NOT SUBMERGED IN LIQUID
e) PUMP FILLER OR DRAIN PLUG IS LOOSE
f) FACULTY JOINTS IN SUCTION LINE
CAVITATION
BOOSTER PUMPS
JOCKEY PUMP

7. DISCHARGE OF WATER: THE DISCHARGE OF WATER WILL DEPEND ON
FOLLOWING FACTORS
a) PRESSURE OF THE PUMP
b) FLOW THROUGH PIPE
c) THE VOLUME OF THE IMPELLER CASING
d) THE ROTATION AND DESIGN OF THE IMPELLER
e) BRAKE POWER
f) SUCTION DEPTH AND DISCHARGE HEIGHT
g) THE TEMPERATURE AND VISCOSITY OF THE LIQUID
h) CONDITION OF SUCTION AND DISCHARGE HOSES
i) CONDITION OF STRAINER

8. SUCTION LIFT
DISCHARGE HEIGHTS
LESSON 2 – FLOW OF WATER
INTRODUCTION
ENERGY: THE LIQUID IS ALWAYS HAVING ENERGY IN IT. THE WATER WILL
HAVE FOLLOWING ENERGY
a) POTENTIALENERGY
b) PRESSURE ENERGY
c) KINETIC ENERGY

9. POTENTIAL ENERGY
PRESSURE ENERGY
KINETIC ENERGY
BERNOULLIS PRINCIPLE
TOTAL ENERGY
ENERGY LOSS:
a) LOSS DUE TO FRICTION OF THE WALL
b) LOSS AT THE ENTRANCE OF PIPE
c) LOSS AT THE EXIT POINT OF PIPE
d) LOSS DUE TO CHANGE IN SIZE OF THE PIPE
e) LOSS DUE TO VARIOUS PIPE FITTINGS
f) LOSS DUE TO TURNS AND CURVES
g) LOSS DUE TO BLOCKAGES AND POOR MAINTENANCE

10. PARALLEL PIPES: PARALLEL PIPES ARE USED FOR MOVEMENT OF LARGE
QUANTITY OF WATER OVER LONG DISTANCE. THIS REDUCVES ENERGY
LOSS AND EASY FOR MAINTENANACE
LAWS OF FLUID FRICTION: THE FLUID IN MOTION IS SUBJECTED TO
CERTAIN BASIC
FRICTIONAL LAWS
a) THE FRICTONAL RESISTANCE IS PROPOTIONAL TO THE VELOCITY.
b) THE FRICTIONAL RESISTANCE IS INDEPENDENT OF THE PRESSURE.
c) THE FRICTIONAL RESISTANCE IS PROPOTIONAL TO THE SURFACE
AREA.

11. d) THE RESISTANCE VARIES WITH TEMPERATURE AND VISCOCITY OF
LIQUID.
e) THE FRICITON IS INDEPENDENT OF THE NATURE (SMOOTHNESS) OF
SURFACE.
f) THE FRICTION IS PROPOTIONAL TO THE DENSITY PF THE LIQUID
CRITICAL VELOCITY
FLOW OF WATER: THE WATER FLOW VARIES IN PIPE DUE TO TYPE OF
PUMP , PIPE AND FRICTION . THE TYPES OF PIPE CAN BE CHARACTERISED
AS FOLLOWS:
a) STEADY AND UNSTEADY FLOW
b) UNIFORM FLOW
c) LAMINAR FLOW AND TURBULENT FLOW
d) ROTATIONAL FLOW
e) COMPRESSIBLE FLOW

12. STEADY AND UNSTEADY FLOW:
UNIFORM FLOW:
LAMINAR FLOW:
TURBULENT FLOW:
ROTATIONAL FLOW:
COMPRESSIBLE FLOW;
WATER HAMMERING:
a) THE SPEED AT WHICH VALUE IS CLOSED
b) THE VELOCITY OF FLOW
c) THE LENGTH AND DIAMETER OF THE PIPE
d) THE ELASTIC PROPERTY OF THE MATERIAL OF PIPE
e) THE RATE AND EFFICIENCY OF PUMP
SURGE TANK:
RESERVOIRE CONNECTING PIPES:
