What is the ‘CHECK TRANS’ procedure? |
1. Do not select or change any gear 2. Notify workshops (MES) immediately via VKN8 - place vehicle out of commission 3. Drive vehicle to nearest fire station or as directed by workshops 4. Apply the handbrake and leave engine running. Do not select neutral |
|
|
What type of pump does the MKV Pumper have? |
Darley 1000 series mid-mounted single stage centrifugal pump with additional high pressure stage. Rated at 3800L/min at 1000kPa |
|
|
Auxiliary pump function: |
Allows operation of the high pressure reels without needing to engage pump master, main pump or second stage pump |
|
|
What is the procedure for engaging/disengaging the main and 2nd stage pump? |
1. Apply the park brake and place transmission in neutral 2. Switch on the pump master electrical switch in the cabin (pause) 3. Switch on the 2nd stage pump switch (pause) 4. Switch on the main pump switch 5. Listen to hear the pumps have engaged 6. Exit the appliance and check both main and 2nd stage pump lights are illuminated on primary pump panel
To disengage, do the same in reverse, pausing for lights to go off |
|
|
What are some pre-pumping checks to ensure problem-free pumping? |
-ensure engagement lights are on -check emergency shutdown hasn’t been activated (light illuminated) -throttle switch is on the setting you wish to use (manual/auto) -ensure the pump to tank valve is switched to open (unless you have already established a feed) -ensure the pressure relief valve lever is switched OFF |
|
|
Ideally, hose reels should be run above what pressure/flow? |
2000kPa, approx. 200L/min (Pumper has capacity to deliver 470L/min through 2 reels simultaneously = approx. 235L/min each) |
|
|
The delivery outlets (1-4) supply 38, 50 and 65mm firefighting lines. What is the safe flow rate and ideal operating pressure for these? |
450L/min 1000kPa (main/low pressure pump) |
|
|
What are the following capacities of the DeckMaster electric remote monitor (L/min)? Water: ? Foam (3%): ? Foam (6%): ? |
Water: 3800L/min Foam (3%): 3800L/min Foam (6%): 2650L/min |
|
|
Blitzfire portable ground monitor capacity and angle capability? Water: ? Foam (3%): ? Foam (6%): ? Elevation angle: ? Horizontal angles: ? |
Water: 2000L/min Foam 3%: 2000L/min Foam 6%: 2000L/min Elevation angle: 10-50 degrees above horizontal Horizontal angle: 20 degrees either side of centre |
|
|
Precautions for ground monitors: |
-must be manned at all times -should not exceed 1200kPa -should be tied off when possible -legs fully extended |
|
|
When relay pumping which pump needs to set the pressure relief valve? |
The delivering pump (this should be in manual mode) |
|
|
In relay pumping which pump sets the suction relief valve to prevent damage from a sudden increase in pressure? |
The receiving pump |
|
|
What does the suction relief valve do? |
Protects the receiving pump from excess pressure entering suddenly |
|
|
What does the pressure relief valve do? |
It is set by the delivering pump in order to prevent excess pressure from being delivered through a hose line when another one is closed suddenly |
|
|
What are some considerations when siting the Pumper? |
-wind direction -proximity to incident and water supply -direction the panel faces -oncoming appliances |
|
|
How does impeller cooling work? |
Constant bleed lines automatically ‘bleed’ a small amount of water from the main and 2nd stage pump discharge back into the water tank. This allows cool water to enter the pump. |
|
|
Why is priming necessary when pumping from open water? |
Impellers do not pump air. A primer is required to remove air from inside the pump and allow atmospheric pressure to push water into the system. |
|
|
What is the Pumper Tanker seating capacity? |
5 people |
|
|
What are the differences between the Pumper and Pumper Tanker? |
-Methods to engage the pump (PTO from driveshaft, not transmission) -The auxiliary pump can be operated from inside the cabin -Specifications -Cabin protection/deluge system (preset flow of 160L/min) |
|
|
What are the key differences between the Foam Pro and Foam major systems? |
The Foam Pro: -is used in conjunction with the hose reels and no.2 deliveries. -allows simultaneous delivery of both water and foam -injects foam concentrate AFTER the pump -can deliver a maximum of 3% concentrate -pump capacity 670L/min The foam major: -can deliver 0.1-10% concentrate -foam concentrate is added before the pump from either tank or bulk supply -delivers through any outlet that is open -pump capacity of 159L/min -max delivery 3800L/min |
|
|
What is the max delivery of 3% foam from the foam major system? |
3800L/min |
|
|
What is the max delivery of 6% foam from the foam major system? |
2650L/min |
|
|
What does IZMIF stand for? |
Isolate Zero Meter Induct Foam on |
|
|
Explain the MKV Pumper driveline: |
It’s a direct driveline. When operating on the road: Engine flywheel>Auto transmission>driveshaft>diff>rear axle and wheels When operating pump: Engine flywheel>PTO>Darley pump and 2nd stage pump |
|
|
Explain the MKV Pumper Tanker driveline: |
It’s a ‘split-shaft’ driveline - which as the name suggests draws power from the middle of the vehicle driveshaft via a PTO. The engine powers the pump instead of the rear wheels. |
|
|
Rules of thumb for calculating flow through high pressure hose reels: |
1000kPa = 80L/min 2000kPa = 200L/min 3000kPa = 270L/min (1 hose) 3000kPa = 470L/min (shared between 2 hose reels) |
|
|
For AdBlue diesel appliances on which side is the tank located? |
Nearside |
|
|
What 4 systems does the aux pump ignition switch activate? |
1. Auxiliary electrics 2. Foam Pro 3. Hose reel rewind 4. Scene lighting |
|
|
Why does the MFB use the Foam Major system and not the Foam Pro? |
The Foam Pro used both A and B class foams, but the A class foam is carcinogenic and has been known to clog injectors. The Foam Pro also only delivers up to 3% foam. |
|
|
Why is simulate mode important? |
For use with foam via the HP hose reels. The HP reels do not have automatic metering when used in conjunction with the Foam Major. It’s necessary to enter the flow rate manually in order to calculate the amount of foam required. |
|
|
When do CFA auto primers operate? |
When pressure drops below 150kPa. |
|
|
What are the key considerations for a pump operator? |
Branch operators: you should have accountability to them and know their general whereabouts. You should deliver the correct/safe pressure to them. Water supply: connect to and maintain supply sufficient for firefighting requirements |
