1、操作前檢查項(xiàng)目
1. Inspection items before operation
平口攪拌車空氣系統(tǒng)運(yùn)行前檢查潤(rùn)滑油油位,保持油位在油尺上下線之間,接近下及時(shí)提高油位線。,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、添加潤(rùn)滑油的注意事項(xiàng)
2. Precautions for adding lubricating oil
①加油時(shí),應(yīng)無(wú)壓力進(jìn)行。作業(yè)前應(yīng)將平口攪拌車周圍的灰塵等雜物清理干凈,以免進(jìn)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注油器內(nèi)的潤(rùn)滑油為普通柴油機(jī)油,可使用粘度為2.5-7度的潤(rùn)滑油或工業(yè)40#油。儲(chǔ)油杯中的油應(yīng)及時(shí)更換。儲(chǔ)油杯容量以100ml計(jì)算,使用100小時(shí)為宜。
順酐廠家
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、維護(hù)
3. Maintenance
定期清洗空氣平口攪拌車的濾芯。由于濾芯太臟,進(jìn)入壓縮機(jī)氣缸的空氣中含有過(guò)多的灰塵,會(huì)加速氣缸和活塞環(huán)的磨損,容易形成積碳,影響氣閥的密封性能;會(huì)造成拉缸和竄氣,造成潤(rùn)滑油污染,影響潤(rùn)滑效果;當(dāng)氣體被竄氣時(shí),也會(huì)出現(xiàn)油污現(xiàn)象。如果氣缸壁與活塞環(huán)之間的間隙過(guò)大,受污染的潤(rùn)滑油就會(huì)進(jìn)入壓縮室。并形成油霧,污染壓縮空氣。
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.
