To ensure long-term stable operation,
extend service life, and enhance construction efficiency, this systematic
maintenance and servicing guide provides comprehensive instructions covering
daily inspections, periodic maintenance, operational procedures, and
replacement of wear parts. It empowers users to keep equipment in optimal
working condition.
I. Daily Inspection and Maintenance
During routine operation, focus on core
components including the engine, chassis, boom, and hydraulic system.
For the engine and chassis, regularly
inspect engine oil, coolant levels, and electrical circuit functionality to
ensure stable power output. Simultaneously, check connections at the front and
rear axles and transfer case to prevent loosening that could compromise driving
safety.
The boom and outriggers require thorough
inspection for cracks or weld separation at joints. Outriggers must be securely
positioned to guarantee operational safety.
For the lubrication system, regularly apply
grease to the boom, turret, outriggers, and chassis transmission points.
Periodically replace gear oil to ensure smooth operation throughout.
Additionally, maintain proper hydraulic oil
levels and cleanliness. Promptly inspect high-pressure hoses and fittings to
prevent leaks.
II. Regular Maintenance
Regular maintenance is essential for the
efficient operation of pump trucks. Replace diesel, engine oil, air, and
hydraulic oil filters according to specified intervals to maintain system
cleanliness.
Rotate the boom delivery pipes periodically
to prevent localized wear. Monitor changes in pipe wall thickness and replace
pipes promptly when necessary.
For the electrical system, inspect the
electrical components in the control cabinet and cab to ensure the control
system operates stably. Keep the remote control batteries fully charged to
ensure responsive and reliable operation.
III. Construction Operation Precautions
Before operation, confirm that the pump
truck's outriggers are securely supported and all piping connections are correct
to prevent overturning or slurry leakage during work.
During pumping operations, adjust the
discharge volume appropriately based on site requirements to avoid equipment
damage from high-pressure impacts or low-load operation. Operators must monitor
equipment status in real time and immediately shut down for inspection upon
detecting abnormalities.
After completion, thoroughly clean the
pumping system and piping immediately to prevent concrete residue from causing
blockages or corrosion.
IV. Wear Parts Management and Maintenance
During prolonged use, components such as
delivery pipes, wear plates, cutting rings, and rubber springs are
high-frequency wear items. Familiarize yourself with their performance
characteristics and replacement cycles. Follow the “outside-in,
easy-to-difficult” replacement principle to ensure efficient and safe
maintenance.
During maintenance, use appropriate tools
to avoid secondary damage from improper operation. For complex or difficult
faults, promptly contact professional maintenance personnel or manufacturer
support to prevent escalation of issues.
Scientific and standardized maintenance is
crucial for ensuring the efficient and safe operation of pump trucks. By
implementing routine inspections, periodic maintenance, standardized operation,
and professional repairs, users can effectively enhance equipment reliability
and construction efficiency, providing solid support for project development.
