一、为什么要去掉解放牌汽车空压机的余隙容积目前在解放牌汽车上使用的空压机是气冷双缸活塞式空压机。在空压机缸盖上有一个空间——余隙容积(图1)。其作用是: (1)使贮气筒内的压力维持在额定限度以内,当贮气筒内压力到达9公斤/厘米~2时,空压机停止泵气; (2)使空压机的排气量随着需要改变,贮气筒内 First, why remove the clearance volume of Jiefang card car air compressor The air compressor currently used in Jiefang card car is air-cooled double cylinder piston air compressor. There is a space on the air compressor cylinder head - clearance volume (Figure 1). Its role is to: (1) to maintain the pressure within the gas cylinder within the rated limit, when the pressure in the gas cylinder reaches 9 kg / cm ~ 2, the air compressor to stop pumping; (2) the air compressor exhaust The volume changes as needed, inside the cartridge
