Transmission to neutral


Engage HP pump


Engage main pump


Transmission to drive

Types of solar panels

Grid connect


Standalone

Disengage pump

Transmission to neutral


Wait 5 second


Disengage main pump


Disengage HP pump

What does the transfer case do

The transfer case directs power between the engine and the pump

Centrifugal pump

In a centrifugal pump energy is imparted by centrifugal force. Force is created by rotation of an object. The force drives outward from the centre of rotation.

Components of the pump

Impeller - heart of the pump, consists of the: Eye (water drawn in) and The vanes (water thrown out)


The volute - houses the impeller

Priming pump

Rotary vane pump.


To pump air out of main pump

Relief valve purpose

A safety mechanism to protect branch operators on 64mm hose lines.

When is the relief valve set?

Commencement of shift or before required operation.

Default position for relief valve

Off.


Only required when operating with 64mm hose lines.

How to set relief valve

Ensure throttle is at idle


Turn relief valve on


Wind pressure to HI


Open tank to pump


Open a 64mm delivery


Increase to 1000kpa


Wind back relief valve until green light comes on


Increase relief valve slightly to knock off.

Isolating solar

Next to panel


Next to inverter


In fuse box

When do you not use a relief valve

HP hose lines


Boosting


Relaying


38mm hose lines

Pump damage

Cavitation


Overheating


Water hammer


Also,


Water directed through relief valve


Operator error


Water quality

Advantages of water

Cheap


Available and plentiful


Absorbs heat


Expands 1700 to 1 to steam


Easily transported

Disadvantages of water

High surface tension


Reactive with certain chemicals and materials


Low viscosity


Will conduct electricity

5 principles of friction loss

Varies directly with length of hose


For the same velocity, Decreases with increase in diameter


Increases directly as the square velocity (m/s)


Increases with roughness of hose


Independent of pressure

Reduce friction loss by:

Eliminate sharp bends


Use adapters only when necessary


Keeling branches and valves fully open


Use proper size gaskets


Use short lines when possible


Use large hoses or multiple lines

Friction loss measurements

64mm - 100kpa


38mm - 200kpa


1m - 10kpa

MOW

Why use SOPs

To provide a number of known procedures that allow firefighting crews to operate in a manner which is - systematic, efficient and predictable

Why use SAPs

Provide administrative and protocol to staff
