3. Water suction system
1) Floating pump
- Pump type: single-stage single-suction centrifugal pump
- Composition: large flow fire pump, hydraulic motor, pontoon,
filter, etc.
- Weight: ≤100kg
- Export caliber: 250mm
- Water inlet direction: water inlet at the bottom (the floating boat
pump works more stably)
- Flow rate: 200L/s, pressure 0.4MPa, with filter screen.
- Working temperature: -25℃ ～ +50℃
- Pump body material: pump body and impeller are cast high-strength
light alloy
- Application: It can float on the water to absorb water, the maximum
vertical water intake height can reach 20 meters, and the
horizontal water intake distance can reach 60 meters.
2) Independent engine
- Rated power: 275kW @ 2100rpm;
- Maximum torque: 1550N.m @ 1100rpm—1400rpm
- Intake form: turbocharged & air-to-air cooling
3) Hydraulic system
- System composition: The hydraulic system is composed of a plunger
pump, a control valve, a hydraulic oil tank, a hose reel, hydraulic
motor, etc.
- Power transmission: The system provides hydraulic power through the
engine-driven hydraulic plunger pump. Under the control of the
hydraulic valve, it is supplied to the hydraulic motor through the
hydraulic hose to drive the suction pump.
- Automatic hydraulic hose reel: The hydraulic hose reel is composed
of the main body of the reel, the 60-meter oil return hose (with
high-strength wear-resistant fiber sheath outside), the slewing
mechanism, the guiding mechanism, and the automatic pipe arranging
mechanism. The hydraulic hose reel can be freely released when it
is unfolded, and can be automatically rewinded when it is recycled.
4) Water intake hose
- The system is equipped with a DN250 hose of 120m, two each of 30m,
20m, and 10m, which are used for two sets of floating pumps to take
water.
- Material: Double-sided molding at one time.
5) Control system
The control system has a high degree of automation. It should adopt
a vehicle controller or be better than this system. It can manually
adjust the engine speed and the working pressure of the pump set,
and can display the speed, pressure and other parameters in real
time.
4. Booster system
The booster system can be used independently, either as an
independent system for boosting water supply, or in combination
with other remote water supply systems, as a two-stage or
three-stage booster module. The booster system is composed of
engine, booster pump, coupling, low water inlet and outlet
pipeline, control system, etc. The actual continuous operation time
is not less than 7 days. When 3 kilometers, ensure that the total
flow at the end is not less than 200L/s, and the end outlet
pressure is not less than 0.2MPa.
1) Engine
- Brand: Cummins
- Model number: P750
- Rated power: 750HP
2) Booster pump
- Model number: TBC08/400G
- Structure type: single stage double suction
- Rated flow: 400L/s
- Rated pressure: 0.8MPa
- Inlet pipe diameter: 2×250mm (matching with suction pump outlet
pipe)
- Outlet pipe diameter: 2×300mm (matching the diameter of the main
water supply line)
- Working temperature: -25℃ ～ +50℃
5. Truck-mounted crane
1) Function
- The truck-mounted crane is installed at the rear of the vehicle and
can rotate 90 degrees left and right;
- Equipped with two sets of winches, one of which is installed on the
boom head, used to lift two floating pumps when taking water
vertically, and the other is installed on the basic arm, equipped
with two sets of vertical water supply elbows, used for lifting
DN250 when taking water vertically Take the water hose.
- When taking water from the ramp, the hoist of the crane is used to
release and recover the suction pump.
- Vertical water supply elbow: It is used to hang on the crane boom
when taking water from the bridge deck and wharf to avoid the water
belt being smashed and the railing crushed when the water belt is
directly placed on the railing when taking water.
2) Performance parameters
- Lifting capacity: 18t.m
- Maximum working radius: 16 m
- Lifting capacity with maximum working radius: 500kg
- Rotation angle: 360°
- Hoist one: 0.5T/40m
- Windlass 2: 4T/20m
6. Internal purge system
- The internal purge system adopts compressor air supply and is
equipped with a large displacement compressor. The internal purge
system should be able to purge more than 85% of the accumulated
water in the water belt.
- Purge principle and operation: adopt the mature oil pipeline pig
principle, put the water-absorbent elastic purge device on the
surface into the hose before purge, connect the special interface
for purge, open the purge valve, compressed air pushes purge The
ball moves quickly in the hose, pushing the remaining water in the
hose and absorbing water stains on the inner surface of the hose.
