The function of the lubricator in the mixer truck is to atomize the lubricating oil and inject it into the air flow into the parts that need to be lubricated with air. Therefore, the lubricating oil in the oiler must be kept in the normal position, neither too much nor too little. So what is the relevant content of inspection and maintenance before and after the lubricating oil of the oil atomizer of the mixer truck?
1. Inspection items before operation
Before the operation of the air system of the full-automatic mixer truck, check the lubricating oil level, keep the oil level between the upper and lower lines of the dipstick, and raise the oil level line in time when it is close to the lower limit., The sealing ring at the mouth of the oil cup is intact.
2. Precautions for adding lubricating oil
① When refueling, there should be no pressure. Before operation, dust and other sundries around the mixer shall be cleaned to avoid entering the oiler.
② The lubricating oil in the oiler is ordinary diesel engine oil, and lubricating oil with viscosity of 2.5-7 degrees or industrial 40# oil can be used. The oil in the oil cup should be replaced in time. The capacity of the oil storage cup is calculated as 100ml, and it is appropriate to use it for 100 hours.
Clean the filter element of the air mixer regularly. Because the filter element is too dirty, the air entering the compressor cylinder contains too much dust, which will accelerate the wear of the cylinder and piston ring, easy to form carbon deposition, and affect the sealing performance of the air valve; It will cause cylinder pulling and gas channeling, cause lubricating oil pollution, and affect the lubrication effect; When the gas is channeled, oil pollution will also appear. If the gap between the cylinder wall and the piston ring is too large, the contaminated lubricating oil will enter the compression chamber. And form oil mist, polluting the compressed air.
Regularly carry out the maintenance of the items specified in the maintenance procedures, such as cleaning, lubrication, refueling, etc
Before starting the mixer, check whether each controller is in good condition. After shutdown, pour water and stones into the mixing drum for 10-15 minutes for cleaning, and then remove the water and stones. If the operator needs to enter the mixing drum for cleaning, he must not only cut off the power supply and remove the fuse, but also lock the switch box.
It is forbidden to use a sledgehammer to remove the concrete accumulated in the mixer drum, and only a chisel can be used to remove it.
In the severe cold season, after the work of the full-automatic mixer truck is completed, the mixer drum shall be cleaned with water and the accumulated water in the water pump, water tank and water pipe shall be drained to avoid freezing damage of the water pump, water tank and water pipe.
If you want to prolong the service life of the mixer truck, you must operate in strict accordance with the correct method!
