ATOS柱塞泵回油过程快ATOS柱塞泵出油阀关闭迅速 ATOS柱塞泵回油过程:柱塞向上供油,当上行到柱塞上的斜槽(停供边)与套筒上的回油孔相通时,泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通,油压骤然下降,出油阀在弹簧力的作用下迅速关闭,停止供油。此后柱塞还要上行,当凸轮的凸起部分转过去后,在弹簧的作用下,柱塞又下行。此时便开始了下一个循环。ATOS柱塞泵的泵油机构包括两套精密偶件:柱塞(plunger)+柱塞套(barrel)构成柱塞偶件(plunger and barrel assembly)(图5-11)、出油阀(delivery valve)和出油阀座(delivery valve seat)构成出油阀偶件(delivery valve assembly):华 : ATOS柱塞泵回油过程快ATOS柱塞泵出油阀关闭迅速 AGIR-10/210/V AGIR-10/350 AGIR-20/210 AGISR-20/210V AGIU-20/10/100/D/V-IN24DC WG AGMZO-A-010/100 AGMZO-A-010/210 AGMZO-TERS-PS-010/210/I AGMZO-TERS-PS-10/210 AGMZO-TERS-PS-10/210/I AGMZO-TERS-PS-10/210/I AGMZO-TERS-PS-32/315 AGRCZ-A-020/100 AGRCZO-A-010/100 AGRCZO-A-010/100/P AGRCZO-A-010/315 AGRCZO-A-10/210 AGRCZO-A-20/210/R AGRCZO-AE-20/210/P AGRL-10-2 AGRL-20/2 AGRLE-10 AGRLE-20 AQFR-10 ARAM-20/10/210-IN24DC ARAM-20/210 ARE-06/350 ARE-06/50 ARE-06/500/V ARE-15/15/44 ARE-15/50/V ARE-15/75 C-14128 CK-25/12*100-Z308-23 CK-32/14*0280-D901 CK-32/22*0250-L002D1Y1AW CK-32/22*0250-L002D1Y1AW CK-40/18*0182-D901 CK-40/28*160-D001A CK50/36*0200-E001 CK-63/36 X 0265-C601-30 DB-10/G DB-5/G DH-0113 DH-0143 DH-014450 DH-0151 DH-0431/2 DH-0914 DHA/UL-0611/A/NPT 24DC DHA/UL-0631/2/A/NPT 24DC DHA/UL-0631/2/NPT 24DC DHA/UL-0713/NPT 24DC DHA-0611/A/NPT 24DC DHA-0630/2/PA-GK DHA-0631/2/7NPT DHA-0631/2/A/NPT 24DC DHA-0631/2/NPT 24DC DHA-0631/2-1/2NPT DHA-0711/GK DHA-0713/NPT 24DC DHA-0713/PA-GK 24DC DHA-0713P/PA-GK-24DC DHA-1711/2/NPT 24DC DHI-0610-L3/15 DHI-0610-X24DC DHI-0611 DHI-0614-X230AC DHI-0630/2 DHI-0631/2- N230AC DHI-0631/2/A-N24DC DHI-0632/2 24DC DHI-0632/2-N24DC DHI-0639/0 X24DC ① ATOS柱塞往复运动总行程L是不变的,由凸轮的升程决定。
② 柱塞每循环的供油量大小取决于供油行程,供油行程不受凸轮轴控制是可变的。
③ 供油开始时刻不随供油行程的变化而变化。
④ 转动柱塞可改变供油终了时刻,从而改变供油量。 |
