1、操作前检查项目
1. Inspection items before operation
平口搅拌车空气系统运行前检查润滑油油位,保持油位在油尺上下线之间,接近下及时提高油位线。,油杯口密封圈完好。
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、添加润滑油的注意事项
2. Precautions for adding lubricating oil
①加油时,应无压力进行。作业前应将平口搅拌车周围的灰尘等杂物清理干净,以免进入注油器。
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注油器内的润滑油为普通柴油机油,可使用粘度为2.5-7度的润滑油或工业40#油。储油杯中的油应及时更换。储油杯容量以100ml计算,使用100小时为宜。

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.
3、维护
3. Maintenance
定期清洗空气平口搅拌车的滤芯。由于滤芯太脏,进入压缩机气缸的空气中含有过多的灰尘,会加速气缸和活塞环的磨损,容易形成积碳,影响气阀的密封性能;会造成拉缸和窜气,造成润滑油污染,影响润滑效果;当气体被窜气时,也会出现油污现象。如果气缸壁与活塞环之间的间隙过大,受污染的润滑油就会进入压缩室。并形成油雾,污染压缩空气。
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.
