» Ⅳ. Hydraulic Conveying Principle:
Equipped with a Weilong 80QZ60/90 centrifugal pump, the pump boosts pressure to circulate water.
• Impeller Rotation: Engine power drives the impeller at high speed, creating a negative pressure zone at the center of the impeller.
• Water Intake and Pressurization: Water is drawn in through the stainless steel pump inlet. After being accelerated by the centrifugal force of the impeller, it flows along the pump casing into the outlet, significantly increasing pressure (up to 0.8-1.2 MPa).
• Bidirectional Water Delivery: By switching the valve, the pump can achieve the full "pumping-storage-delivery" process, meeting the needs of various scenarios.

» Ⅴ. Application Scenarios
• Municipal Water Supply: Providing clean drinking water to remote areas or temporary water points.
• Emergency Rescue: Rapidly deploying mobile water sources after disasters such as earthquakes and floods, as well as firefighting at the scene of a fire.
• Engineering Support: Drinking water distribution to construction sites, mines, and field troop logistics support facilities.
• Municipal Greening: Can be used as a sprinkler for road washing and landscaping.
