How To Maintain Concrete Pumps ?
Regular and proper maintenance is necessary and crucial to ensure the safety, reliability, efficiency and long service life of concrete pumps. As an important construction tool, concrete pumps bear the heavy responsibility of delivering concrete to the construction site. Without regular maintenance, the pump components may suffer from damage, wear, clogging and leakage, which may affect the efficiency of the pump and even lead to damage of equipment and personal injury accidents.
Therefore, regular maintenance of concrete pumps can ensure the normal operation of the equipment, reduce downtime, improve efficiency and construction quality, as well as extend the service life of the equipment and provide a more secure and reliable guarantee for the construction.
In order to maintain the concrete pump, all structural and wearing parts need to be checked for defects. This includes the piston, specification plate, cutting ring, stabilizer, electrical control device, hopper, moving arm, hydraulic control device, and all piping.
In terms of maintenance, the following points need to be considered:
Lubrication and oiling
Lubrication is considered to be the most important aspect of regular or routine maintenance of concrete pumps.
Most concrete pumps are equipped with an automatic lubrication system that automatically lubricates all parts that need to be lubricated.
However, it is vital to check the automatic lubrication system daily to ensure that it is always full. If the automatic lubrication system fails, the operator can manually lubricate the parts using the grease gun on the concrete pump.
Concrete pump operators should also check the water and oil levels in the wash tank daily.
Remember to check the overall condition of the vehicle, including the tires and oil, as industrial use of concrete pumps can cause extreme wear and tear on all parts of the vehicle.
What we know about the chassis has a major impact on the life of the pump truck. It is the determining factor in how long a pump truck will ultimately work.
The stability of a concrete pump truck is also supported and maintained by the chassis. More importantly, the chassis serves as the power source for the long-term uninterrupted operation of the concrete pump truck. The chassis must be kept in good working condition.
The engine is the heart of the vehicle and provides the driving and operating power for the concrete pump truck through the connection with the whole transmission and drivetrain.
Check the oil level and condition of the engine.
Check the coolant level and water temperature of the engine.
Check the oil pressure in the engine.
The transmission system of the concrete pump consists of gearbox, transfer case and drive shaft, which is like the aorta in the human body, distributing the power to the drive wheels and hydraulic pump continuously.
Check the wear and pressure of the tires.
Check the electrical system.
Check all the pilot lights.
Check for oil and gas leaks, and tighten joints if any.
Check safety devices such as limit switches and safety locks.
Check that all moving parts (such as fixed legs and boom) are in a fixed position before moving the pump truck.
Maintenance of structural parts
The alternating forces and severe vibration of the whole machine during pumping operation may cause the concrete pump to run poorly, resulting in loose structural parts or broken welds; therefore, inspection of the pump truck structure is especially necessary.
If the structural parts are loose or broken and are not found and repaired in time, a catastrophic accident may occur, leading to damage or even death of the machine. Therefore, operators must pay close attention to them when inspecting structural parts.
Electrical System Maintenance
Make sure that all components of the electrical system are working properly and consistently.
To avoid component damage, make sure that wires are fully insulated, especially those that are tied or stretched tightly.
Check that wire connections are secure and free of oxidation.
Make sure your electrical system is properly grounded. Theoretically, electrical component replacements must use the same parts as the original. Parts that need to be replaced must be inspected by goods of the same grade and standard.
Maintenance of concrete conveying pipes
After some wear and tear, the supply pipe can be rotated periodically. The elbow is rotated 180 degrees and the straight pipe is rotated 120 degrees clockwise.
The wear and tear of the conveying pipe must be checked regularly. If the thickness is less than the specified value, the pipe should be replaced. This can be verified using the empirical hammering method, which involves calculating the tube thickness based on the change in the sound heard. Of course, measuring with a thickness gauge is a more scientific method.
Use original fittings and do not add tubes after the boom is completed. Straight pipes and elbows with a staff distance of less than 3 meters must be replaced when the wall thickness wears out.
Maintenance of cleaning system
Clean water should be used. Impurities in the water are very likely to clog the water pipes, especially the connection with the water tank, affecting the life of the pump. Filters and tanks must be cleaned regularly to remove dirt.
Proper maintenance of the concrete pump is an important measure to ensure safe, efficient and reliable operation of the equipment. Maintaining concrete pumps can effectively extend the life of the equipment and reduce production stoppages caused by equipment failure, while improving construction quality and efficiency.
Regular maintenance can ensure that the pump components are in good condition and reduce damage and wear, thus improving the efficiency and reliability of the pump. Maintenance includes routine operations such as cleaning, lubricating and tightening of bolts, as well as inspection and maintenance of the pump structure, piping and electrical system.
