The mechanical seal is made of silicon carbide, which is leak-proof and suitable for long-term operation.

• Corrosion-resistant pump (100-200KW) : The flow-through components (impeller, pump casing) are made of 304 stainless steel (for common corrosion) or fluoroplastic (for strong corrosion), with an acid and alkali resistance range of pH 2-12. The sealing parts are made of fluororubber and are suitable for the transportation of chemical waste liquid.

3. Intelligent Control System (KCPLC-04 Pump Exclusive Edition)

• Core functions:

① Fluid parameter monitoring: Real-time display of flow rate (turbine flowmeter) and head (pressure sensor), and alarm when exceeding the range (such as low flow rate indicating filter screen blockage).

② Safety protection: When operating without water (detected by the liquid level sensor), the machine will automatically shut down within 3 seconds (to protect the mechanical seal). When the engine has high water temperature and low oil pressure, it will automatically reduce the load and shut down.

③ Mobile adaptation: Medium and large-sized models support remote monitoring via mobile APP (4G network connection), allowing for location (GPS positioning) and operational status viewing, making it suitable for multi-vehicle dispatching.

④ Multi-vehicle linkage: Large models support parallel control of 8 vehicles, with a load balancing deviation of no more than 5%, meeting the demand for large-scale drainage.

4. Full-environment adaptation optimization

• Protection design: The small section is IP54 (rain splash-proof and dust-proof), and the medium/large section is optional IP65 (short-term immersion in a water depth of 0.5m). The surface of the vehicle body undergoes a triple anti-rust process of "acid washing and phosphating + galvanizing + powder coating" (salt spray resistance test ≥500 hours), making it suitable for humid and coastal environments.

• Low-temperature start-up: In environments below -25℃, an optional "oil preheater + coolant preheater + fuel heater" (three-preheating system) can be installed. The start-up success rate is ≥99%, and it can operate normally in northern winters.

• Quick deployment: The water pipe interface adopts quick couplings (DN50-DN200), and the water pipe connection can be completed within 10 minutes. Medium and large-sized models are equipped with folding water pipe racks (capable of storing 50-100 meters of high-pressure water pipes), eliminating the need for additional handling tools.

2.Power recommendation for typical scenarios

Usage Method (Exclusive operation for Mobile Water Pump trucks)

1. Pre-startup inspection (with a focus on moving and fluid components)

2. Startup operation (power distribution process)

(1) 20-50KW (small)

1. Trailer fixation: Park the vehicle on a flat ground. No support legs are needed (small ones do not). Pull the handbrake tightly.

2. Pipe connection: Connect the water inlet to the suction pipe (placed in the water source, with a depth of ≥1 meter), and connect the water outlet to the drain pipe.

3. Startup and operation: Open the fuel valve → Controller "manual" mode → Preheat for 30 seconds (low temperature) → Start the engine → Observe the rotational speed (1500r/min) → After the self-priming pump starts discharging water (about 1 minute), adjust the rotational speed until the flow rate meets the standard.

(2) 100-200KW (Large)

1. Trailer fixation: After the vehicle comes to a complete stop, extend the hydraulic support legs (operated with one button on the controller), lock the vehicle when it is level, and activate the ABS braking system.

2. Pipeline connection: quick joint docking suction/drainage pipe, check the seal (no leakage);

3. Start and run: "manual/automatic" mode of the controller → air start (press the starting valve) → check the oil pressure after the engine starts (≥0.3MPa) → start the water pump → graded loading (20%→50%→100%), and adjust the flow to the demand value through the controller.

3. Operation monitoring and shutdown

• Real-time monitoring: record flow rate, head, engine water temperature (≤95℃) and oil pressure (≥0.2MPa) every 30 minutes;For large vehicle models, the location and multi-vehicle status can be checked through the APP to prevent pipe disconnection and water shortage.

• Exception handling:

① Flow drop: stop to clean the water filter (impurity blockage), check whether the suction pipe is leaking (self-priming pump);

② Abnormal sound of water pump: stop and check the impeller (whether there is a foreign body stuck), bearing (wear needs to be replaced);

③ Trailer shift: large models immediately stop, readjust the support legs to ensure the level;

• Shutdown process:

① Unloading: reduce the speed to idle speed, turn off the water pump → turn off the inlet/outlet valve;

② Stop: press the "stop" button of the controller → close the fuel valve;

③ Finish: withdraw the support leg (medium/large), dish the water pipe, clean the filter impurities, and record the operation data.

Safety and Protection (Exclusive Specifications for Mobile Water Pump Trucks)

1. Driving safety (Core of the movement process)

• Traction requirements:

① Small vehicle models need to be towed by pickup trucks of ≥1.5 tons, and medium/large ones need to be towed by trucks of ≥5 tons. The towing ropes/rods must comply with the GB/T 25980 standard.

② Before driving, check the connection of the towing hook (locked in place), tire pressure (≥0.8MPa), and braking system (large ones with ABS self-check).

③ On rural roads, the speed should be no more than 30km/h; on expressways, it should be no more than 60km/h. When turning, slow down (no more than 20km/h) to avoid rollover.

• On-site safety

①When working, set up warning signs (triangular signs, warning lights) and prohibit non-operating personnel from entering within a radius of 5 meters.

When the suction pipe is placed in the water source, someone should supervise it to ②prevent it from falling into the water. The outlet of the drainage pipe should be kept away from people to prevent injury from high-pressure water spraying.

2. Operational Safety (Fluid and Mechanical Risks)

• Personnel requirements:

① Operators must hold a "Motor Vehicle Driving License" (C1 or above, for towing small vehicles) or B2 (for towing large vehicles), and pass the specialized training provided by Kecheng.

②When working, wear anti-slip shoes and waterproof gloves. When in contact with corrosive liquids, wear acid and alkali resistant gloves to avoid burns from the medium.

• Operating contraindications:

① Do not operate the water pump without water (even a short period of time will damage the mechanical seal).

② Do not start large vehicles when the support legs are not fully extended (the vehicle body is unstable and prone to displacement).

③ It is prohibited to convey media that exceed the capacity of the water pump (for example, if a regular pump conveys strong acids, a corrosion-resistant pump should be used).

• Emergency response:

① Water pipe burst: Stop the machine immediately, close the valve and replace the water pipe.

② Engine fire: Use dry powder fire extinguishers to put out the fire (water is prohibited), and evacuate people.

③ Leakage fault: Disconnect the power supply, wear insulating equipment to check the wiring, and do not touch electrical components without protection.

3. Maintain safety (Focus on moving parts)

• Preparations before maintenance:

① Disconnect the engine power supply, close the fuel valve, and hang a warning sign that reads "Under maintenance, Do not start".

②For large vehicles, the support legs should be retracted, the vehicle should be parked on a flat ground, and the brakes should be tightened.

③ Clean the residual medium in the water pump (for sewage pumps, rinse with clean water; for corrosive pumps, clean with neutralizing solution).

• Key maintenance:

① Trailer system: Check the tire wear (tread depth ≥1.6mm) and the oil level of the hydraulic support legs (up to the mark) weekly. Lubricate the traction hook (add grease) and check the thickness of the brake pads (≥3mm) every quarter.

② Water pump system: Clean the filter screen monthly, check the mechanical seal (without leakage) every 3 months, and replace the bearing grease (3# lithium-based grease) every 6 months.

③ Engine system: Change the engine oil (15W-40), oil filter and air filter regularly. Strictly use original parts from Kecheng to avoid losing the warranty.
