Introduction
Hubei Shengda Automobile Co., Ltd., located in the renowned automotive modification hub of Suizhou, Hubei Province, has been making significant strides in the production and sales of specialized vehicles. With a strategic location where multiple highways and railways intersect, the company benefits from excellent transportation connectivity, facilitating the efficient distribution of its products. This case study focuses on the company's cooperation in the production and supply of sprinkler trucks, highlighting the innovative solutions it has provided to meet the diverse needs of customers.
The Client and Their Challenges
The client in this case is a large - scale urban environmental protection service provider operating in a bustling city with a population of over 5 million. The city, like many others, faced several challenges in maintaining a clean and dust - free environment. With rapid urbanization, the construction activities had increased exponentially, leading to a substantial rise in dust pollution on the roads. The existing fleet of sprinkler trucks was outdated, with a low water - carrying capacity and inefficient spraying systems. These old - model trucks could only carry 5 - 7 cubic meters of water, requiring frequent refills. The spraying width was limited to about 8 - 10 meters, and the water pressure was insufficient to effectively clean the stubborn dirt and dust accumulated on the roads, especially in construction - heavy areas.
Moreover, the client was under pressure to meet the increasingly strict environmental protection regulations. The local government had set ambitious targets to reduce particulate matter (PM) pollution in the air by a certain percentage within a specific time frame. The client needed to upgrade its sprinkler truck fleet to not only improve the efficiency of road cleaning but also contribute to the overall air quality improvement in the city.
Hubei Shengda's Sprinkler Truck Solution
Vehicle Design and Construction
Hubei Shengda Automobile Co., Ltd. designed and produced a new generation of sprinkler trucks tailored to the client's needs. The trucks were built on a high - quality, durable chassis sourced from a well - known domestic manufacturer. The chassis was selected for its excellent load - bearing capacity and reliable performance, ensuring that the vehicle could operate smoothly even on rough urban roads.
The water tank of the sprinkler trucks was a key feature. It was constructed using high - strength, corrosion - resistant steel plates with a thickness of 5 - 6 mm. This not only increased the durability of the tank but also allowed for a larger water - carrying capacity. The new trucks had a water tank volume of 12 - 15 cubic meters, which was almost double the capacity of the client's previous vehicles. This larger capacity meant that the trucks could operate for a longer time between refills, reducing the time wasted on trips to water - filling stations.
Spraying System Innovation
The spraying system of the new sprinkler trucks was a significant upgrade. Hubei Shengda installed a multi - nozzle spraying system that could adjust the spraying width and water pressure according to different road conditions. The spraying width could be adjusted from 12 - 20 meters. For example, in wide arterial roads, the spraying width could be set to the maximum 20 - meter range, covering a large area in one pass. In narrower streets or areas with parked cars, the width could be reduced to 12 meters to ensure targeted spraying without wetting unnecessary areas.
The water pressure was adjustable from 300 - 800 kPa. In construction areas where there was thick layers of dust and mud on the roads, the water pressure could be increased to 800 kPa. This high - pressure water jet was powerful enough to wash away even the most stubborn dirt. The nozzles were designed with a special anti - clogging mechanism. Made from high - quality stainless steel, the nozzles had a fine - tuned orifice that could prevent debris and impurities from blocking the water flow. Additionally, the nozzles were arranged in a specific pattern to ensure uniform water distribution across the spraying area.
