Precautions During the Pre-Operation Preparation Phase for Cooling Mist Vehicles

Pre‑operation verification of cooling‑mist vehicles is a critical prerequisite for preventing subsequent malfunctions. The prevailing industry standard mandates that all preparatory procedures be completed before power and water are connected. Drawing on 20 years of experience in misting‑equipment R&D, Guangzhou Aogong has distilled the following standardized checklist:

1. Verify the vehicle’s exterior and chassis condition, ensuring that tire pressure is normal and the braking system is functioning properly.
2. Verify the water lines of the spray system, ensuring that all fittings are leak-free and that the filter screens are unobstructed.
3. Prior to energizing the circuit system, verify that the voltage parameters are compatible and that the grounding protection devices are in good condition.
4. Verify the internal cleanliness of the water tank, ensuring that no foreign objects are present and that the water used for filling meets hygiene standards.

Key points to note during the water tank filling process of a cooling‑mist vehicle

When filling the water tank of a cooling‑mist vehicle, do not use unfiltered municipal wastewater or highly hard well water. Prolonged use of hard water can lead to scale buildup inside the nozzles, clogging the spray openings. According to industry test data from 2026, water with a hardness exceeding 300 mg/L can reduce nozzle service life by more than 40%. It is recommended to prioritize neutral‑pH water that has been settled and filtered. During refilling, verify that the tank’s water level gauge is functioning properly to prevent false readings.

Key Verification Points for Compatibility of Cooling Mist Vehicle Accessories

Before each operation, the cooling‑mist vehicle must verify that the nozzle type matches the intended application: for example, use a 100‑mesh atomizing nozzle for cooling and dust suppression, and a 200‑mesh ultra‑fine atomizing nozzle for disinfection. Using an incompatible nozzle not only compromises performance but can also cause abnormal pressure spikes, damaging the high‑pressure pump’s critical components. If you are unsure about the appropriate nozzle configuration, please contact the Guangzhou Aogong technical team for on‑site verification, or visit www.aoopo.com to consult the corresponding compatibility table.

Precautions for On-Site Operation of Cooling Mist Vehicles

Once the cooling‑mist vehicle enters the formal operation phase, the operator’s adherence to established procedures directly determines both operational efficiency and the rate of equipment wear. Industry experts generally agree that operators who have undergone systematic training exhibit a 75% lower incidence of equipment misoperation compared with those lacking experience.

Key Points for Starting the Cooling Mist Vehicle and Pressurizing It

When starting the cooling‑mist vehicle, first start the engine and let it idle for 3–5 minutes to warm up, then activate the misting system in no‑load mode. Once the system is running smoothly, gradually adjust the pressure to the operating range specified for the task. Do not immediately set the pressure to the maximum setting, as this can subject the high‑pressure pump to excessive instantaneous load and lead to component wear. Field‑operation data from 2026 show that adhering to proper pressurization procedures can extend the service life of the high‑pressure pump by more than two years.

Key Points for Dynamic Monitoring of the Operation of Cooling Mist Vehicles

During operation, the operator of the cooling‑mist vehicle must continuously monitor three key parameters: system working pressure, residual water level in the tank, and nozzle atomization condition. If sudden pressure spikes or drops, a water level falling below the alarm threshold, or individual nozzles failing to produce mist occur, operations must be immediately halted to identify and rectify the fault; the equipment must not be allowed to run for extended periods under abnormal conditions.

Precautions for Adapting Cooling Mist Vehicles to Different Scenarios

Cooling‑mist vehicles exhibit markedly different operational requirements across various application scenarios, making it impossible to apply uniform operating parameters. Drawing on 20 years of practical experience in deploying mist‑spraying systems, Guangzhou Aogong has compiled the following comparative table of optimized parameter settings for mainstream applications in 2026:

Key Adaptation Points for Open-Air High-Temperature Work Environments

When operating in outdoor high-temperature conditions above 35°C during the summer, cooling‑mist vehicles should have their continuous run time appropriately shortened. After every two hours of operation, pause for 15 minutes to allow the high-pressure pump to cool down. At the same time, avoid directing the mist directly at pedestrians to prevent ultrafine water droplets from entering the respiratory tract and causing discomfort. Operators should also wear basic protective masks to ensure their own safety.

Key Considerations for Dust Suppression in Mining Areas

When operating in mining areas, cooling mist vehicles should increase the spray system pressure as needed and be equipped with a secondary water‑quality filtration unit to prevent fine particulates in the local water supply from clogging the nozzles. The spray angle should be directed upwind of the dust‑generation source to enhance both dust suppression and cooling effects.

Precautions for the Daily Maintenance and Upkeep of Cooling Mist Vehicles

Routine maintenance of cooling‑mist vehicles is a key strategy for extending equipment lifespan. According to an industry report published in 2026, equipment that undergoes regular, standardized maintenance achieves an average mean time between failures more than three times longer than that of equipment receiving no such routine upkeep.

Key Cleaning Points After a Single Operation of the Cooling Mist Vehicle

After each operation, the cooling‑mist vehicle must drain any remaining water from the tank, rinse the tank interior with clean water, and then run the low‑pressure clean‑water mode for 3–5 minutes to flush out residual impurities from the piping, thereby preventing scale or foreign matter from accumulating in the lines and causing future blockages.

Key Points for Periodic Component Inspection of Cooling Mist Vehicles

For every 100 hours of operation, the cooling‑mist vehicle should have its nozzles disassembled to inspect for nozzle‑hole wear, verify that the high‑pressure pump’s lubricant level is within the specified range, and calibrate the pressure gauge’s accuracy. If any component shows signs of wear, promptly replace it with genuine OEM parts. Replacement parts can be purchased at www.aoopo.com to ensure stable equipment performance.

Precautions for Storing Cooling Mist Vehicles and Discontinuing Use During Seasonal Changes

When cooling‑mist vehicles are left idle for extended periods or stored during cold seasons, inadequate protection can easily lead to pipe freezing and cracking, component corrosion, and other issues—problems that account for roughly 38% of non‑natural equipment failures.

Key Points for Storing Cooling Mist Vehicles in Low-Temperature Environments

When a cooling‑mist vehicle is parked in temperatures below 0°C, all water must be completely drained from the water tank, piping, and the high‑pressure pump to prevent freezing and expansion from causing component cracks. If conditions permit, the equipment should be stored in an indoor, insulated garage; alternatively, insulating sleeves can be fitted over the exterior of the piping.

Key Protective Measures for Long-Term Storage of Cooling Mist Vehicles

When the cooling‑mist vehicle is expected to remain out of service for more than 15 days, all metal transmission components should be coated with anti‑rust oil, the vehicle’s main power switch should be disconnected, and personnel should be scheduled to energize the system and run it at no load for five minutes each week to prevent moisture‑induced degradation of electrical components.

Safety Precautions and Emergency Response Guidelines for Cooling Mist Vehicles

During operations, if a sudden abnormality occurs, operators must follow standardized procedures to carry out emergency response measures and minimize losses.

Key Emergency Procedures for Sudden Malfunctions of Cooling Mist Vehicles

If, during operation, the cooling‑mist vehicle experiences sudden incidents such as pipeline rupture or an abnormal surge in pressure, immediately press the emergency stop button to cut off the equipment’s power supply. Then, drain any pressurized water remaining in the pipelines before identifying and addressing the fault. Under no circumstances should components be disassembled while the pipelines remain pressurized, to prevent high‑pressure water from spraying and causing personal injury.

Key Points for Daily Safe Operation of Cooling Mist Trucks

Operators of cooling‑mist vehicles must undergo specialized training before commencing work. Minors and personnel without operational experience are prohibited from operating the equipment at will. During operation, the equipment must maintain a safety clearance of at least 3 meters from nearby high‑voltage power facilities to prevent electrical conductivity in the mist that could create safety hazards.
