As an efficient dust removal and cooling device, proper maintenance of the fog cannon machine after use is crucial for extending its service life and maintaining good performance. The following are the maintenance methods for the fog cannon machine after use:
1、 Comprehensive cleaning and basic inspection
Appearance cleaning
Wipe the equipment casing with a clean and damp cloth to remove surface dust, mud, and debris, paying special attention to areas that are prone to blockage such as the air inlet and outlet. Stubborn stains can be assisted by neutral cleaning agents, but it is necessary to avoid liquid infiltration into the electrical compartment or motor interior.
Spray system maintenance
Nozzle unblocking: Check the nozzles one by one for blockage, and use a fine needle or specialized tool to clean the nozzle holes to ensure even atomization effect.
Pipeline inspection: Check for leaks at pipeline connections, fix loose joints, and replace damaged sealing rings.
Water quality management: Drain residual water from the water tank, regularly clean the tank to prevent algae growth, and add antibacterial agents if necessary.
2、 Deep maintenance of core components
Fan system maintenance
Blade inspection: Observe whether the fan blades are worn, deformed, or cracked. If there is severe damage, they should be replaced immediately.
Dust cleaning: Disassemble the air duct components and use compressed air to blow away the internal dust, especially the gaps between the motor cooling channel and the guide vane.
Lubrication of transmission components: Apply high-temperature resistant grease to rotating parts such as bearings and gears to reduce friction losses.
Power system maintenance
Fuel powered models: Change the engine oil (use for 20 hours first, and every 50 hours thereafter), clean the air filter; Check the aging condition of the fuel pipe.
Motor type: Check the firmness of the power line connector, measure the insulation resistance value to be ≥ 2M Ω; clean the dust inside the electrical control cabinet to prevent short circuits.
Hydraulic and fastening structures
Check the hydraulic oil level of the pitch adjustment device and horizontal slewing support, and replenish or replace the anti-wear hydraulic oil.
Perform torque verification on all bolted connections, with a focus on reinforcing load-bearing parts such as tower bases and support pin shafts.
3、 Professional debugging and long-term storage
Functional Testing
Start the equipment for a short time to verify the smooth operation of the fan and whether the spray pressure is normal, and calibrate the pressure gauge to the standard range (usually 25-30kg/cm ²).
Test the response speed of remote control and automatic swing function to eliminate signal interference issues.
Winter storage
Drain the water pump and pipeline to prevent freezing and cracking; Disassemble easily corroded parts and store them separately.
Cover with dust cover and place desiccant, manually rotate once a month, and maintain bearing lubrication.
Scientific maintenance can not only reduce the failure rate, but also significantly improve the efficiency of equipment operation. Suggest developing a personalized maintenance plan based on the equipment manual and implementing remote monitoring through an IoT platform to provide early warning of potential faults.
