摘要
通过对奶山羊挤奶时的压力、挤奶频率的测试和分析,结果表明,较合适的山羊挤奶机脉动器的性能参数为: 脉动频率f=62(1/分);脉动真空Va.=350(mm Hg柱高),节拍比PR=50％.
After testing and analyzing the pressure and pulsating frequencies in goats milking, we obtained the results showing that the performance parameters of a pulsator would be more reasonable when the pulsating frequency(f) is about 62(1/minute), the degree of vacuum(Va) is about 350(mm mercury- column), the phase ratio (PR) is about 50%.
