Against the backdrop of the nationwide initiative to build civilized cities in the new era, local governments across China are actively advancing urban construction and placing greater emphasis on municipal sanitation—resulting in large-scale procurement of sanitation water-sprinkling trucks. Hubei Chengli Group, leveraging its mature technologies accumulated over many years and robust independent innovation capabilities, has consistently led the industry in the sprinkler truck segment. Orders from governments at all levels, corporate clients, and individual buyers continue to rise steadily. Chengli sprinkler trucks serve as “urban beauticians” across the country, operating on the front lines of urban aesthetic enhancement campaigns—working diligently every day on city streets. Ensuring these “urban beauticians” remain healthy, reliable, and long-lasting is therefore critically important. Below, we share essential daily maintenance and servicing guidelines for landscaping sprinkler trucks. 1. Water Source Requirements When using rivers, ditches, or ponds as water sources, the suction hose’s intake end must be fully submerged. To prevent ingestion of stones, excessive silt, or floating debris, a filter device is typically installed at the suction hose’s inlet—this filter must never be removed. It is recommended to refill from deeper water sources. If the water source is shallow, excavate the suction area deeper in advance to ensure it remains free of debris and air ingress. Different sprinkler trucks employ different types of pumps—clear-water pumps require virtually impurity-free water, whereas turbid-water pumps tolerate some sediment but must not draw in stones or excessive silt. 2. Vacuum Requirement for Suction Pipes The suction pipe system must maintain a certain vacuum level during water intake to successfully draw water into the tank. The entire suction system must be airtight and leak-free: rubber hoses must show no damage, and rigid pipes must have no cracks; otherwise, air leakage will occur, preventing effective water suction. 3. Priming Before Pumping Centrifugal-pump sprinkler trucks require priming—i.e., adding a specified volume of water into the pump before each suction cycle. After priming, the filler cap must be securely closed. Self-priming pumps require priming only upon initial use; subsequent operations do not require additional priming. 4. Draining Water in Winter Before winter arrives, all water must be completely drained from the pump and pipelines to prevent freezing and cracking. In northern China, where construction typically halts during severe winter months, water should be drained immediately after project completion to avoid potential damage. 5. Parking Brake Engagement During Operation Whether drawing water or spraying, the power take-off (PTO) gear must only be engaged when the vehicle is fully stopped and the parking brake is applied. 6. Post-Operation Maintenance After returning to base: – Thoroughly clean the sprinkler truck; – Check and replenish fuel, engine oil, and coolant; – Inspect fan and water pump drive belts for proper tension—adjust if necessary; – Check tire inflation pressure and sealing integrity of all gearboxes; – Inspect and organize onboard tools and accessories. 7. Regular Tank Drainage and Sludge Removal The water tank is equipped with a drain pipe whose inlet is located at the tank’s lowest point. After extended operation, periodically open the drain valve to flush out accumulated sediment and debris until the discharged water runs clear. As a member of China’s Top 500 Private Enterprises, Chengli Group stands confidently on its strong brand reputation—and remains committed to maintaining its leadership position in the industry.
