How does concrete pump maintenance?
Concrete pump maintenance can enlarge working life with good condition, reduce the risk of working condition, save replacement time and money in the future. Only treat concrete pump as a tool to make money and do not maintain concrete pump parts, or insist maintain it with regularly. These two cases have different life for the concrete pump.
Among the daily expenses, the replacement cost of wearing parts is the most, because most of the parts are in a worn state when the concrete pump is working. Therefore, the consumption of wearing parts is relatively large, including pipeline tubes, wear plates, cutting rings, pistons, S valve tube pipes, concrete cylinders, mixer systems, etc. Also electrical system should be inspected regularly careful.
Times for concrete pump maintenance
Check and inspect the concrete pump based on regularly and schedulely. Only in this way can ensure the concrete pump truck is efficient, safe, reliable with a long service life. For more information, click it.
Content of concrete pumping maintenance
The maintenance of concrete pumping is including chassis, electrical system, hydraulic system, distribution system and cleaning system.
The operator must perform maintenance with the instruction manual, and made maintenance plan for damage concrete pump spare parts. This will reduce the failure rate of the concrete pump truck. Good maintenance will make concrete pump with safe, efficient.
Tips for concrete pumping chassis maintenance
The chassis is a key to affecting the life of the pump truck. This is the factor that determines how long the pump truck will eventually work.
The chassis also supports and maintains the stability of the concrete pump truck. More importantly, the chassis is also the power source for the long-term and uninterrupted operation of the concrete pump truck. The maintenance of the chassis is essential. Although the vehicle is not running, the engine and transmission ware working when pouring.
The specified or recommended oil specification must be used for regular replacement.
Lack of coolant and lubricating oil is strictly prohibited.
Engine - the heart of chassis
The engine, which is the heart of the vehicle, provides driving and working power for the concrete pump truck through the connection with the transmission device and transmission system of the whole machine.
Check the oil level and condition of the engine oil.
Check the coolant level, coolant level and water temperature in the engine.
Check engine oil pressure.
Regularly replace the engine oil and engine oil filter element
Clean the crankcase regularly.
Add lithium grease regularly.
Proper battery maintenance can increase the battery life.
Transmission system—the aorta of the chassis
The transmission system of the concrete pump includes: gearbox, transfer case and transmission shaft, like the aorta of the human body, which continuously transmits power to the driving wheel and hydraulic pump.
Check tire wear and pressure.
Electrical system inspection (lighting, indicator lights, stop lights).
Inspection of rear view mirrors.
Check all guide lights.
Check for oil and gas leaks, if oil leaks, tighten the fittings.
Inspection of safety devices such as limit switches, safety latches.
Before the pump truck is moved, check that all moving parts (such as fixed outriggers, booms) are fixed in a fixed position.
Tips for concrete pumping electrical systems maintenance
Check that all electrical system components operate correctly and reliably.
Ensure complete insulation of wires, especially bundled or stressed wires, to avoid damage to components.
Check whether the connection of the wire is firm and free of oxidation.
Check that the electrical system is well grounded.
Clean all instruments and lamps regularly.Clean all instruments and lamps regularly.
The replacement of electrical components must, in principle, use the same accessories as the original price. If any replacement parts are required, they must be inspected products of the same grade and standard.
Tips for concrete pumping hydraulic system
The hydraulic system is the key to the concrete pump, because the hydraulic system is the power source, including the boom and the main cylinder. Once the hydraulic system has a problem, it is likely that some action on the concrete pump can not be completed, which is often referred to as the hydraulic fault. Therefore, the daily maintenance of the hydraulic system is also very important. For the hydraulic oil, as the transmission medium, is also very important in the entire hydraulic system.
Check the oil level gauge of the pump truck to ensure that the hydraulic oil level cannot be lower than the minimum working level when it works normally.
Check whether the cooling system of the pump truck works normally.
Check the hydraulic pipeline for oil leakage.
The mixing system and transfer case are prone to hydraulic oil leakage.
Concrete pumping distribution system
The distribution system is a very important component for concrete pumping.
After the pumping finished, the hopper should be cleaned and no concrete accumulation, otherwise the lower part of the S pipe will be corroded and worn.
After each pumping, the No.1 elbow must be opened to clean the inside of the S pipe to prevent pipe blockage in the next pumping.
Add concrete pumping primer before engine operation.
Adjust the clearance of wear plate and cutting ring every 5000 m3.
Rotate the cutting ring 90 degrees for each 10000 m3 of pumping.
Regularly replenish lubricating oil.
Tips for cleaning system
Clean water must be used. Impurities in the water are easy to block in the water pipe, especially at the connection with the water tank; and affect the service life of the pump. Filters, tanks must be cleaned regularly to remove dirt.
In the low temperature weather, after the end of each day's work, the water in the waterway system should be drained to prevent the water pump or other components from bursting due to water freezing.
In order to ensure the high efficiency, safety, reliability and long working life of the concrete pump, regular and correct maintenance is necessary and crucial, and avoid concrete pumping safety accidents.
