✦Ⅱ.Fire Pump System Of HOWO Fire Water Truck «««

This is the true "heart" of the fire truck. The entire system consists of: engine → transmission → PTO (Power Take-Off) → driveshaft → CB10/40 XZ fire pump. The engine not only drives the vehicle but also diverts power via the PTO to specifically power the fire pump, pressurizing and outputting water for firefighting. Simultaneously, the HOWO light fire truck can also mix foam media for emergency rescue in special fire situations.

1.Power Matching Verification:The output speed of the PTO (Power Take-Off) must match the rated speed of the CB10/40 XZ pump.The power margin should be reserved to avoid insufficient power and the pump failing to reach its rated pressure under full load.

2.Driveshaft Coaxial Alignment:The three driveshafts (gearbox PTO, PTO fire pump) must be coaxial. Misalignment will cause vibration, rapidly wear down the driveshaft bearings and the pump's mechanical seal, leading to leaks and abnormal noises.

3.Sealing Surface Installation Specifications:Clean the old gaskets and impurities from the PTO-gearbox mating surfaces and the pump body flange surfaces. Apply sealant evenly and use brand-new sealing paper gaskets. Do not reuse old gaskets to prevent air intake and oil leakage.

4.Piping Layout:Keep the suction pipe as short as possible with minimal bends. Excessive bends in the pipe will increase suction resistance and directly reduce water intake capacity. All flange connections must be equipped with complete rubber sealing rings.

5.Electrical wiring:The circuits of the double piston priming device, pressure switch, and residual water switch must be reliably grounded. The residual water switch function must be properly connected and dry-run protection must be provided to prevent the pump from running dry and burning the seals.

✅After installation:Perform a sealing pressure test, a no-load test run, and a complete water priming test to confirm that there is no air leakage or seepage before putting it into use.

Centrifugal pumps cannot automatically draw water, the air inside the pump chamber must first be evacuated to create a vacuum before water is forced into the pump by atmospheric pressure. This process is called priming. This pump is equipped with an electric dual-clutch dual-piston priming device, supporting two operating scenarios:

Scenario 1:Drawing water from external water sources such as ponds and ditches (self-drawing water)

1. Park the fire truck securely, engage the PTO (Power Toll Collection) device, and close all outlet valves. Connect the suction hose to the water filter and place it in the water, ensuring the suction hose is not submerged in silt to avoid sucking in sediment that could damage the impeller.

2. Press the priming switch. The dual-piston vacuum pump will operate, removing air from the pump chamber and piping.

3. Once the pressure gauge indicates pressure buildup, priming is complete, and the priming mechanism will automatically disengage. Immediately shut off the priming and adjust the engine speed to output pressurized water.

✅Maximum self-priming depth:Do not exceed the priming depth, ≥5, otherwise priming will fail.

Scenario 2:Vehicle-mounted water tank / Municipal fire hydrant water supply (no vacuum priming required)

Water tanks and fire hydrants have built-in pressure supply. Simply open the corresponding valve, and water will naturally fill the pump chamber. Adjust the pump speed to dispense water; no priming device is needed.

❗Common problem for beginners:Priming fails repeatedly? 90% of the time, the problem isn't a faulty pump, but a leaking pipe joint. Air gets in and prevents a vacuum from being established. Check gaskets, connections, and valves for tight seals.

Operational Prohibitions:

❌ Engage PTO while the vehicle is moving.

❌ Start the water pump without putting it in neutral and engaging the handbrake.

❌ Never run the fire pump dry for an extended period without water.

❌ Forgetting to shut off the priming mechanism after priming is complete; continued operation will burn out the priming piston assembly.

❌ Do not allow silt to settle directly into the suction pipe; mud and sand will enter the pump body and damage the impeller and seals.

❌ Under high pressure conditions, rapidly and forcefully closing the outlet valve will cause water hammer, damaging the pump body and pressure gauge.

Routine Maintenance (Simple and Easy to Perform, Extends Lifespan Several Times)

1.After each operation, drain any residual water from the pump chamber (using the drain plug), especially in low-temperature environments, to prevent freezing and cracking of the pump body; flush the pump chamber to remove mud and impurities.

2. Oil Level Check: Before each use, check the oil level observation window on the pump body and gearbox; if the oil is emulsified and white, it indicates water has seeped into the seals, requiring immediate inspection and replacement of the seals. Change the gear lubricating oil according to the schedule.

Monthly Simple Inspection:

♦Check all interface gaskets for aging and cracking. ·

♦ Test the priming device to confirm that the priming speed is normal. ·

♦ Test the function of the pressure switch and residual water switch. ·

♦ Check for leakage at the pump shaft seal; slight dripping is normal, while heavy dripping indicates seal damage and requires replacement.

✅ Long-Term Storage: Drain and dry the pump chamber; apply rust prevention to flanges and metal parts; do not allow water to remain inside the pump for extended periods.
