供应dgmx2-3-pp-ah-b-40节流阀由于油液老化或受到挤压后产生带电的极化分子，而节流缝隙的金属表面上存在电位差，故极化分子被吸附到缝隙表面，形成牢固的边界吸附层，吸附层厚度一般为5~8微米，因而影响了节流缝隙的大小。以上堆积、吸附物增长到一定厚度时，会被液流冲刷掉，随后又重新附在阀口上。这样周而复始，就形成了流量的脉动。 dgmc2-3-at-cw-bt-cw-41 dgmc2-3-at-cw-bt-bw-41 dgmc2-3-at-gw-bt-bw-41 dgmc2-3-at-gw-bt-cw-41 dgmc2-3-at-gw-bt-gw-41 dgmc-3-bt-bw-41 dgmc-3-bt-cw-41 dgmc-3-bt-gw-41 dgmr 3 a1 fwa b1 fwa 50 dgmr1-3-pp-cw-b-40 dgmr1-3-pp-fw-s-40 dgmr1-3-pp-fw-b-40 dgmx1-3-pp-aw-b-40 dgmx1-3-pp-bw-s-40 dgmx1-3-pp-bw-b-40-en12 dgmx1-3-pp-bw-b-40 dgmx1-3-pp-cw-b-40 dgmx1-3-pp-fw-b-40 dgmx1-3-pa-bw-b-40 dgmx2-3-pp-aw-b-40 dgmx2-3-pp-aw-s-40 dgmx2-3-pp-bw-b-40-en13 dgmx2-3-pp-bw-b-40 dgmx2-3-pp-bw-s-40 dgmx2-3-pp-cw-b-40 dgmx2-3-pp-cw-s-40 dgmx2-3-pp-fw-b-40 dgmx2-3-pp-fw-s-40 dgmx2-3-pp-yw-b-40 dgmx2-3-pp-bk-b-40 dgmx2-3-pp-ah-b-40 dgmx2-3-pp-bh-b-40 dgmx2-3-pp-ch-b-40 dgmx2-3-ppl-fh-s-40 dgmx2-3-ppl-fh-s-40 dgmx2-3-pa-bw-b-40 dgmx2-3-pa-bw-s-40 dgmx2-3-pa-cw-b-40 dgmx2-3-pa-fw-b-40 dgmx2 3 pa yw b 40 dgmx2-3-pa-ch-b-40 dgmx2-3-pb-bw-s-40 dgmx2-3-pb-cw-b-40 dgmx2-3-pb-fw-b-40 kadg5v 7 2c180n ex h mf pd7 h1 11 kdg4v 5 33c50n z m u h7 30 kadg5v 7 2c180n t m f pd 7 h1 1 1 kdg4v 5 33c50n z vm u h7 30 kadg5v 7 2c180n x h m f pd7 h1 11 kdg4v 5 33c50n25 h vm u h7 30 kadg5v 7 2c180n x m f pd 7 h1 1 1 kdg4v 5 33c50n25 m u h7 30 kadg5v 7 2c180n x t h m f pd7 h1 11 kdg4v 5 33c50n25 z m u h 7 30 kadg5v 7 2c180n x t m f pd7 h1 11 kdg4v3 2c03f h m u h7 60 kadg5v 7 2c180n x vm f p d7 h1 11 kdg4v3 2c03f h m u ha7 6 0 kadg5v 7 2c180n100 e m f pd7 h 1 11 kdg4v3 2c03f h vm u h7 6 0 kadg5v 7 2c180n100 ex h m f pd7 h1 11 kdg4v3 2c03f m u h7 60 kadg5v 7 33c130n65 x h v m f pd 7 h1 11 kdg4v3 2c03f z vm u h7 6 0 kadg5v 7 33c130n65 x vm f pd7 h1 11 en40 kdg4v3 2c07n z m u g7 60 kadg5v 7 33c170n ex h m f pd7 h1 11 kdg4v3 2c13n vm u h7 60 kadg5v 7 33c170n h m f p d7 h1 11 kdg4v3 2c13n z m p h7 60 en47 kadg5v 7 33c170n x h m f pd7 h 1 11 kdg4v3 2c13n z m u g7 60 kadg5v 7 33c170n x h m f pd7 h 1 11 en40 kdg4v3 2c20n h m u g7 60 kadg5v 7 33c170n x h vm f pd7 h1 11 kdg4v3 2c20n h m u ha7 6 0 kadg5v 7 33c170n x m f p d7 h1 11 kdg4v3 2c20n m u g7 60 由于节流阀的流量不仅取决于节流口面积的大小，还与节流口前后的压差有关，阀的刚度小，故只适用于执行元件负载变化很小且速度稳定性要求不高的场合。 kbdg5v-5-2c90n-x-h-m1-pe7-h1-10 kbdg5v-5-2c90n-x-t-m1-pe7-h1-10 kbdg5v-5-33c80n-x-m1-pe7-h1-10 kbdg5v-7-2c180n-t-m1-pe7-h1-10 kbdg5v-7-2c180n-x-h-m1-pe7-h1-1 kbdg5v-7-2c180n-x-mi-pe7h1-10 kbdg5v-7-2c180n-x-t-m1-pe7-h1-10 kbdg5v-7-2c180n-x-t-m1-pe7-h1-10 kbdg5v-7-33c-130n65-x-m1-f-pe7-h1-10 kbdg5v-7-33c130n-65x-m1-pe7-h1 kbdg5v-7-33c170n-m1-pe7-h1-10 kbdg5v-7-33c170n-m2-pe7-h1-10 kbdg5v-7-33c170n-x-h-m1-pe7-h1-10 kbdg5v-7-33c170n-z-m1-pe-h1-10 kbdg5v-8-2c330n200-m2-pe7-h1-10 kbdg5v-8-2c330n-m1-pe7-h1-10 kbdg5v-8-2c330n-m2-pe7-h-10 kbdg5v-8-2c330n-t-m1-pe7-h1-10 kbdg5v-8-2c330n-x-h-m1-pe7-h1-10 kbdg5v-8-33c330n200-x-m1-pe7-h1-10 kbdg5v-8-33c330n200-x-m2-pe7-h1-10 kbdg5v-8-33c330nm1pe7h11 kbfdg4v-3-2c20n-z-pc7-h7-10 kbfdg4v-3-2c20n-z-pe7-h7-10 kbfdg4v-3-2c20n-z-pe7-h7-10 kbfdg4v-5-2c70n-zpe7h7-110 kbfdg4v-5-2c70n-zpe7h7-110 kbfdg4v-5-33c50n-z-pe7-h7-10 kbfdg5v-5-2c95n-x-m1-pe7-h4-10 kbfdg5v-5-2c95n-x-m1-pe7-h4-10 kbfdg5v-7-2c200n-x-m1-pe7-h4-10 f3-cvi-25-c10f-h-40 f3-cvi-25-d16-l-40 f3-cvi-25-d10-h-40 cvi-32-d10-l-40 cvi-32-d10-m-40 cvi-32-d10-h-40 cvi-32-d105-m-40 cvi 32 d20 2 l 10 cvi 32 d20 2 m 10 cvi 32 d20 2 h 10 cvi-32-d16-l-40 cvi-32-d16-m-40 cvi-32-d16-h-40 cvi-32-r16-l-40 cvi-32-r16-m-40 cvi-32-r16-h-40 cvi-32-dc16-m-40 cvi-32-c10f-h-40 cvi-32-x2-40 cvi-32-u-40 cvi-32-hfv-20-a-63-10 cvi-32-zd105-l-10 cvi-32-zd105-m-10 cvi-32-zdn105-l-10 cvi-32-zdn105-m-10 f3 cvi 32 d20 2 l 10 f3 cvi 32 d20 2 m 10 cvi-40-d10-m-40 cvi-40-d10-h-40 cvi-40-d10-c-40 cvi-40-d105-l-40 cvi-40-d105-m-40 cvi 40 d105v h 40 cvi-40-d105v-h-40-10 cvi-40-d16-l-40 cvi-40-d16-m-40 cvi-40-d16-h-40 cvi 40 d20 2 l 10 cvi 40 d20 2 m 10 cvi 40 d20 2 h 10 cvi-40-r16-l-40 cvi-40-r16-m-40 cvi 40 f 2 l 10 cvi 40 f 2 m 10 dbw30b2-5x/1006ag110nk4 dbw20b2-5x/1006ag110nk4 dbw10b2-5x/1006ag110nk4 dg5s-h8-2c-2-m-u-h5-50 dg5s-h8-2c-2-t-m-u-a5-50 dg5s-h8-2c-2-t-m-u-h5-50 dg5s-h8-2c-e-m-u-h5-60 dg5s-h8-2c-m-u-h5-41 dg5s-h8-2n-2-t-m-u-a6-41 dg5s-h8-3c-t-m-u-h5-60 dg5s-h8-4c-e-vm-u-a5-50 dg5s-h8-4c-e-vm-u-h5-50 dg5s-h8-521c-2-e-t-m-u-h dg5s-h8-6al-e-m-u-h5-60 dg5s-h8-6c-2-m-u-h5-50 dg5s-h8-6c-2-vm-u1-h5-70（带插头） dg5s-h8-6c-m-u-d6-41 dg5s-h8-8c-2-e-vm-u-h5-5 dg5s-h8-8c-2-s-vm-u-a5-50 dg5s-h8-8c-2-s-vmu-a6-41 dg5s-h8-oc-2-s-m-u-h5-50 丹尼逊 t6d-031-1r02-b1 t6d-031-2r02-b1 t6d-031-1l02-b1 t6d-031-2l02-b1 t6d-031-1r03-b1 t6d-031-2r03-b1 t6d-031-1l03-b1 t6d-031-2l03-b1 t6d-031-1r00-c1 t6d-031-2r00-c1 t6d-031-1l00-c1 t6d-031-2l00-c1 t6d-031-1r01-c1 t6d-031-2r01-c1 t6d-031-1l01-c1 t6d-031-2l01-c1 t6d-031-1r02-c1 t6d-031-2r02-c1
