How to correctly use the suction pipe of foam fire truck to absorb water? Operation process of Isuzu foam fire truck discharging water. Operation process of foam fire truck releasing foam

Isuzu foam fire truck has always been popular with older users, and is a popular chassis among Dongfeng fire truck and heavy truck fire truck. Isuzu foam models are divided into: Isuzu 3 ton foam fire truck, Isuzu 3.5 ton foam fire truck, Isuzu 6 ton foam fire truck, Isuzu 12 ton foam fire truck, Isuzu 18-20 ton foam fire truck, etc, These models are the main foam models of Isuzu series. In addition to being sought after by major fire brigades, it is also loved by businesses and communities in various regions. The stable chassis technology and power handling are the reasons for its success.

So the reason for the increase in sales of this type of vehicle is. Today, the editor will provide a comprehensive explanation of the operation steps for this series of models, so that users can have a deeper understanding of it. In fact, detailed operation and maintenance training will be provided when the fire truck manufacturer hands over the vehicles. Today we will fully introduce it. Friends who still don't know, please read carefully.

How to correctly use the suction pipe of foam fire truck to absorb water?

1. Park the fire truck next to the water intake point as close as possible to the water source to shorten the length of the suction pipe

2. Connect the suction pipe head and tail according to the distance of water intake, with one end connected to the fire pump and the other end connected to a water filter and placed in the water.

3. Start the fire pump and vacuum pump to absorb water.

Precautions for using a suction pipe:

1. Do not forcefully drag the suction pipe on the ground to avoid wearing the aluminum interface;

2. When using, the interface must be Tight junction to prevent air leakage and water absorption. When absorbing water from an outdoor water source, a water filter should be installed at the end of the suction pipe, and the depth of the water filter from the water surface should be at least 20ca "30C four to prevent vortices from appearing on the water surface and sucking in air. At the same time, it should be avoided that the water filter comes into contact with the mud surface of the water source to prevent a large amount of mud and sand from being sucked in and damaging the water pump. When there are many mud and sand debris in the water source, a water filter basket should be set on the water filter.

3. The suction pipe should be laid as short and straight as possible. When using coil type suction pipes, the fire truck should be positioned in a position where all coil suction pipes can be placed, to avoid the height of the bend of the suction pipe exceeding the pump's water inlet and creating an "air bag" that affects water absorption.

4. When the water suction pipe crosses the road surface, it is strictly prohibited for vehicles to drive over it, otherwise the water suction pipe will be crushed and cannot absorb water.

 Water outlet operation of Isuzu foam fire truck:

1. Open the rear inlet and outlet valves;

2. Engage the power take-off after pressing the clutch pedal:

3. Slowly release the clutch pedal before slowly filling the fuel door. Connect the water hose and water gun, turn on the water outlet switch, hang the power take-off, turn on the water inlet switch, and add oil. If the water comes out, you can also do it without adding oil, and the pressure is relatively low.

4、 Water suction operation process of Isuzu foam fire truck: the fire truck is equivalent to a water pump, and the fire truck is equipped with a water suction pipe. After the water suction pipe is connected, the water suction operation can be carried out directly

The water tank fire truck can be divided into four parts according to its function.

1. The front part of the fire truck is the driver's cab, where the driver and commander sit.

2. Behind the driver's cab is the location of other firefighters

3. Behind the first rolling shutter of the car body, various tools are placed, including faucets, fire hoses, etc

4. Behind these tools is a water tank for storing fire water. Near the rear of the fire truck is the water pump compartment, which is the place where the water pump is installed. Generally, there are rolling shutters on all three sides of the water pump compartment. When the rolling shutters at the rear are folded up, a display screen displaying the working status of the water pump can also be seen. In the water pump compartment, there are generally necessary tools for using the water pump.

Operation process

1 of foam fire truck releasing foam: start the vehicle, step on the clutch and press the power takeoff (commonly known as the water pump switch). After 3 seconds, slowly release the clutch. At this time, the engine sound is dull, which means that the water pump is hooked up.

2. Turn on the main power switch, the main air source switch and the monitor power switch

3. After confirming that the water outlet valve is open or operating the water cannon in place, open the rear water inlet switch

4. Pressurize to release water. Please note that the pressure and decompression must be slow, as sudden pressurization can easily cause water collapse and injury to people. Sudden decompression will cause water recoil in the hose and hurt people. If foam is needed, open the foam valve.

After the vehicle has discharged water, it is necessary to turn off the water pump switch first to avoid excessive water pressure and damage to the water pump. Then turn off the foam valve, flush the foam in the pipeline and water pump in turn, and then turn off the water. The power supply of the cannon, the main steam source, and the main power switch, and finally discharge the remaining water in the water pump and pipeline. It should be noted that no one should stand at the water outlet and hose connection. Water cannons and water guns cannot be used simultaneously, as the required water pressure for the two is different. Water guns usually have 5 or 6 pressures, while water cannons can reach 12 or 13 pressures.


The above makes it easy to master various operating methods. In fact, once you have a complete understanding of the vehicle, the operation is very simple and the steps are not too complicated! I hope that reading the editor's introduction will provide you with better assistance in operating firefighting vehicles.
