1. Inspection items before operation
Check the lubricating oil level before the air system of the flat-mouth mixer runs, 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 of the oil cup port is intact.
2. Precautions for adding lubricating oil
① Refueling should be carried out without pressure. Before operation, dust and other sundries around the flat-mouth mixer shall be cleaned to avoid entering the oiler.
② The lubricating oil in the oil injector is ordinary diesel engine oil, and the 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 100ml, and it is appropriate to use it for 100 hours.
Regularly clean the filter element of the air flat mixer. 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, easily form carbon deposits, and affect the sealing performance of the air valve; It will cause cylinder pulling and blow-by, cause lubricating oil pollution, and affect the lubrication effect; When the gas is blowby, oil contamination will also occur. 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 to pollute the compressed air.
