Green spraying vehicles play an important role in multiple aspects. Firstly, green spraying vehicles are used for road cleaning, which can wash various road surfaces, reduce dust accumulation, and improve urban hygiene environment. Secondly, it is also used for landscaping, providing irrigation for trees, green belts, lawns, etc., ensuring the healthy growth of plants, and preventing diseases and pests. In addition, green spraying vehicles also have significant effects in dust removal and cooling. They can water and remove dust on construction sites, reduce impurities in the air, and improve air quality. In terms of emergency firefighting, the green sprinkler truck is equipped with a dedicated firefighting interface, which can provide water sources to assist in firefighting work at critical moments. Finally, the green spraying vehicle also has the function of transporting water, which can transport water resources over long distances.
Specific application scenarios include:
1. Urban streets and large factory areas: Rinse and water the road surface to maintain cleanliness and water supply to the green belt.
2. Construction sites: Watering and dust removal to reduce dust and particles in the air and improve air quality.
3. Landscape greening: Provide irrigation for trees, green belts, lawns, etc., prevent diseases and pests, and ensure the healthy growth of plants.
4. Emergency firefighting: Equipped with a dedicated firefighting interface for temporary emergency firefighting watering.
5. Water resource allocation: achieve long-distance water transportation and transport water to the places where it is needed
The QHV5146GPSEB6 green spray wine car is an upgraded product developed by Qihang Automobile. The product adopts the chassis of Dongfeng Motor's cargo truck, equipped with high-altitude operation arm and low-voltage operation system, equipped with hanging blue, 360 "rotary mechanism and telescopic arm, widely used for garden greening pruning, cleaning operations of urban roads, highways, squares and ports, as well as watering operations of plants in green belts.
Green liquor spraying vehicle is a vehicle that uses the power of its engine to drive the on-board sprinkler pump through a power take-off. It adds water to the vehicle from the inlet or transports the water in the tank to various nozzles through pipelines, thereby achieving various functions.
Before the water pump of the green wine spraying truck starts working, the liquid inventory in the pump must be higher than the pump shaft. Therefore, an upward curved pipe must be connected to the pump inlet, followed by a horizontal pipe and a quick connector. The center line of the quick connector must be 300 millimeters higher than the center line of the pump shaft; The imported pipeline system must ensure no air leakage; The suction head of the suction pipe must be submerged underwater to prevent air from being sucked into the water pipe; When connecting the outlet pipeline to the pump outlet, it is necessary to ensure that the length of the straight pipe is ≥ 200mm before connecting the bent pipe.
The sprinkler pump of the green wine spraying vehicle adopts an external mixed self-priming structure, and the pump should contain an appropriate amount of liquid. After the pump is started, the impeller rotates, creating negative pressure at the impeller inlet. The gas in the suction pipeline mixes with the liquid inside the pump and enters the gas-liquid separation chamber through the extrusion chamber. Due to the difference in specific gravity between gas and liquid, the gas is separated from the liquid and discharged from the outlet pipe. The liquid sinks in the gas-liquid separation chamber and circulates multiple times until the gas in the suction pipe is completely discharged and filled with liquid, completing the self-priming process. The pump then begins normal infusion.
The sprinkler pump of the green liquor spraying vehicle can play a role in water absorption and pressurized drainage. The self-priming pump can directly suck the water from the pond into the tank, or connect it directly to the fire hydrant on the city street to inject water and spray water into the tank.
