New energy sanitation vehicles leverage technology to safeguard urban cleanliness, and scientific, standardized maintenance is the key to unlocking their green potential. Today, we are sharing maintenance tips for the 18-ton pure electric sprinkler truck to ensure optimal performance, extend its service life, and make every sanitation operation efficient, eco-friendly, and worry-free.
Daily Maintenance: A daily inspection should include checking the appearance and surface condition of the unit, as well as the tank’s exterior and sealing performance. Inspect pipelines for rust, check each nozzle for dripping and sealing issues, and verify whether nozzle surfaces and ball valves show signs of rust or cracking. Examine the exterior of side and rear protection, as well as the clearance lights, side marker lights, arrow lights, and plate lights. Inspect the appearance of fenders and brackets. Ensure that the upper-body control knobs are functional and that all control functions operate properly. Check the air circuit joints and their sealing, and confirm that the low-water-level alarm is working correctly.
Weekly Maintenance: Inspect the platform exterior weekly. Check all pipeline flanges and ball valve connections for leaks or looseness, and verify that all nozzles are securely fastened. Regularly inspect and clean the filters and three-way filter assemblies. Check the omnidirectional adjustment functions of the front sprayer and opposing spray nozzles, as well as the limit and fixing functions of the landscaping water cannon. Inspect the appearance of pneumatic valves and pipelines.
Monthly maintenance: checking the oil level in the pump bearing housing (the 4-line gauge should be above 2/3 of the sight glass; add oil if below 1/2) and replacing it with 20# mechanical oil; ensuring all ball valves operate smoothly and function properly; inspecting and tightening mounting bolts for the motor, electric control unit, and low-pressure pump; checking the motor and electric control cooling system pipelines and high- and low-voltage wire harness connections; inspecting the low-pressure pump drain balls and function valves; examining the tank for exterior condition, sealing, internal rust, and filter screen status; verifying liquid level gauge markings and seals; inspecting and tightening bolts for structural connections including tank-to-main beam, platform-to-chassis, handrails, pipelines, side and rear guards, lighting fixtures, mudguards and brackets, and splash guards; checking corrugated pipe/air pipe protection for wear; monitoring the vehicle body motor and pump for abnormal noise or vibration; and reviewing body information system data for proper operation.
Quarterly Maintenance: Inspect the unit nameplate, tank surface markings, notices, and rated capacity; check the platform condition; verify the functionality of lighting fixtures; and examine the exterior condition of splash protection devices.
Winter Maintenance: When operating the upper body unit at low temperatures (not below 0°C; operation of the water-spraying vehicle is prohibited below 0°C), inspect the tank, valves, pump, pipelines, and other components for ice before starting work. If ice is detected, it must be removed first. After winter operations, drain any remaining water from the pump, piping system, and tank to prevent freezing and damage to the equipment.
Long-Term Storage Maintenance: Before long-term shutdown of the mounted unit, drain all remaining water from the pump, piping system, and tank to prevent corrosion. At the same time, open all drain ball valves in the tank, pipelines, and pump to ensure the entire system is completely emptied.
