Leading the Way in Special Vehicles: Water Sprinkler Trucks by Hubei Sunny Special Automobile Co., Ltd (CLW Group)

Affiliation: Hubei Sunny Special Automobile Co., Ltd is part of the CLW Group.

A Water Sprinkler Truck is a specialized sanitation vehicle consisting of a chassis, a PTO (Power Take-Off), a water pump, and a tank. Under the manufacturing expertise of CLW Group, these vehicles are designed for:

• Sanitation: Dust suppression, road cooling, and surface washing.
• Greenery: Irrigation for trees and lawns, plus pesticide spraying.
• Construction: Site dust control and high-altitude building cleaning.
• Emergency: Water transport and Emergency Firefighting (equipped with standard fire-hose interfaces).

Equipped with high-power specialized pumps (e.g., Weilong Pump), these vehicles meet the following standards:

• Chassis: Typically built on Class II chassis from brands like Dongfeng, Jiefang, or Foton.
• Tank Construction: Made of high-quality carbon steel or 304 Stainless Steel for specialized requirements.
• Power Train: Engine to Gearbox to PTO to Drive Shaft to Sprinkler Pump.
• Piping System: Includes 4-way 3-point ball valves, filters, and various outlets (front flush, rear sprinkle, side spray).

The truck utilizes the engine's power via the PTO to drive the onboard pump. The pump uses an external-mix self-priming structure:

1. Start: The impeller rotates, creating negative pressure at the inlet.
2. Mixing: Air from the suction pipe mixes with the liquid inside the pump.
3. Separation: Air is discharged through the outlet while the liquid sinks.
4. Circulation: This continues until all air is purged, and the pump begins normal fluid delivery.

Technical Note: The liquid level inside the pump must be higher than the pump shaft. The centerline of the quick-coupling must be at least 300mm above the pump shaft centerline.

1. Suction (Filling): Set the 4-way valve handle perpendicular to the ground. Submerge the hose end at least 300mm. Engage the PTO in neutral.
2. Spraying (Discharging): Set the 4-way valve handle parallel to the ground. Open the desired valves and engage the PTO.
3. Safety: Once the tank is empty, the driver must immediately disengage the PTO to prevent pump damage.

Manufacturers like Hubei Sunny Special Automobile Co., Ltd are prioritizing Energy Saving and Emission Reduction. With government subsidies, the industry is shifting toward New Energy (Electric) sprinkler trucks and innovative environmental technologies.
