一、流量调节板的调整(如图1所示) (1)在机器开动前,先调整联动座上的限位螺钉,使之在落闸后流量调节板与慢辊的间隙处于既不漏粮,也不摩擦的位置,此时限位螺钉应正好顶着流量调节拨叉。 (2)改变流量调节板与慢辊之间的间隙,可以控制流... 一、流量调节板的调整(如图1所示) (1)在机器开动前,先调整联动座上的限位螺钉,使之在落闸后流量调节板与慢辊的间隙处于既不漏粮,也不摩擦的位置,此时限位螺钉应正好顶着流量调节拨叉。 (2)改变流量调节板与慢辊之间的间隙,可以控制流量的大小。在机器开动前,先根据要求,把流量调节滑块调到一定位置,此位置宜小不宜大,以免流量过大发生闷车。在机器开动后,再合上闸,由于物料重量和流量调节拉簧的力量。 展开更多

1.喂入量的调节:喂入量是通过改变流量调节板与慢辊之间的间隙来调节的。 2.磨辊间距的调节:两磨辊的间距由压簧来调节,一般将压簧压缩8~10毫米为宜。 3.壁板和长滑板的调整:当磨辊直径变小时。

AIM To investigate the distribution and function of interstitialcells of Cajal(ICCs) and platelet-derived growth factor receptor-α positive(PDGFRα+) cells in the proximal and distal colon.METHODS The comparison of colonic transit in the proximal and distal ends was performed by colonic migrating motor complexes(CMMCs). The tension of the colonic smooth muscle was examined by smooth muscle spontaneous contractile experiments with both ends of the smooth muscle strip tied with a silk thread. Intracellular recordings were used to assess electrical field stimulation(EFS)-induced inhibitory junction potentials(IJP) on the colonic smooth muscle. Western blot analysis was used to examine the expression levels of ICCs and PDGFRα in the colonic smooth muscle.RESULTS Treatment with NG-nitro-L-arginine methyl ester hydrochloride(L-NAME) significantly increased the CMMC frequency and spontaneous contractions, especially in the proximal colon, while treatment with MRS2500 increased only distal CMMC activity and smooth muscle contractions. Both CMMCs and spontaneous contractions were markedly inhibited by NPPB, especially in the proximal colon. Accordingly, CyPPA sharply inhibited the distal contraction of both CMMCs and spontaneous contractions. Additionally, the amplitude of stimulationinduced nitric oxide(NO)/ICC-dependent slow IJPs(sIJPs) by intracellular recordings from the smooth muscles in the proximal colon was larger than that in the distal colon, while the amplitude of electric field stimulationinduced purinergic/PDGFRα-dependent fast IJPs(fIJPs) in the distal colon was larger than that in the proximal colon. Consistently, protein expression levels of c-Kit and anoctamin-1(ANO1) in the proximal colon were much higher, while protein expression levels of PDGFRα and small conductance calcium-activated potassium channel 3(SK3) in the distal colon were much higher.CONCLUSION The ICCs are mainly distributed in the proximal colon and there are more PDGFRα+ cells are in the distal colon, which generates a pressure gradient between the two ends of the colon to propel the feces to the anus. 展开更多
