自動(dòng)攪拌機遇到活塞敲缸可以采用以下方法處理:
When the piston knocks the cylinder in the automatic concrete mixer, the following methods can be adopted:
(1) 自動(dòng)攪拌機發(fā)動(dòng)機起動(dòng)后,低溫運行時(shí)有敲擊聲,溫度正常后,聲音消失,可以暫不處理,繼續運行。
(1) When the engine of the automatic mixer starts, there is a knocking sound when it runs at low temperature. When the temperature is normal, the sound disappears. It can not be handled temporarily and continue to run.
(2) 發(fā)動(dòng)機溫度正常時(shí),有明顯的敲擊聲,應盡量避免高速運行,盡快拆卸維修。
(2) When the engine temperature is normal, there is obvious knocking sound. Try to avoid high-speed operation and disassemble for maintenance as soon as possible.

(3) 拆下氣缸蓋,抽出活塞以后,發(fā)現氣缸嚴重失圓、拉傷,或者活塞和氣缸的間隙太大,應進(jìn)行更換,更換氣缸套、活塞及活塞環(huán)。
(3) After the cylinder head is removed and the piston is pulled out, it is found that the cylinder is seriously out of round, strained, or the gap between the piston and the cylinder is too large, so it should be replaced. The cylinder liner, piston and piston ring should be replaced.
(4) 如果發(fā)現(混泥土攪拌車(chē))連桿變形,應盡量更換。
(4) If the connecting rod of concrete mixer is found to be deformed, it should be replaced as far as possible.
