擠奶機中真空泵的選擇很重要，如何才能正確的選擇真空泵首先要了解擠奶機的原理，擠奶機由真空泵和擠奶器組成。真空泵主要包括電動機、真空泵、真空調節器和真空壓力表等;擠奶器主要包括擠奶桶、搏動器(或脈動器)、集ji乳ru器qi和he擠ji奶nai杯bei等deng。其qi基ji本ben原yuan理li是shi模mo仿fang犢du牛niu吸xi奶nai，由you真zhen空kong泵beng產chan生sheng負fu壓ya，真zhen空kong調tiao節jie器qi維wei持chi擠ji奶nai過guo程cheng所suo需xu的de真zhen空kong度du，脈mai動dong器qi控kong製zhi擠ji奶nai節jie拍pai，促cu使shi擠ji奶nai機ji內nei在zai壓ya力li下xia降jiang、奶牛乳頭管張開，從而完成奶的擠出過程。
