威格士4520V-42A12/45A12/50A12/60A12-1AA-22R叶片泵,叶片泵分为双作用叶片泵和单作用叶片泵。这种泵流量均匀、运转平稳、噪音小、作压力和容积效率比齿轮泵高、结构比齿轮泵复杂。为了让大家更好的了解叶片泵,接下来将为你介绍双作用叶片泵有什么优点。双作用叶片泵的优点有以下几方面:1、流量均匀,运转平稳,噪声小。2、转子所受径向液压力彼此平衡〃轴承使用寿命长,耐久性好。3、容积效率较高,可达95%以上。4、工作压力较高。目前双作用叶片泵的工作压力为6. 86~10.3 MPa,有时可达20.6 MPa。5、结构紧凑,外形尺寸小且排量大。1.泵转向改变,则其吸排方向也改变叶片泵都有规定的转向,不允许反。因为转子叶槽有倾斜,叶片有倒角,叶片底部与排油腔通,配油盘上的节流槽和吸、排口是按既定转向设计。可逆转的叶片泵必须专门设计。2.叶片泵装配 配油盘与定子用定位销正确定位,叶片、转子、配油盘都不得装反,定子内表面吸入区部分最易磨损,必要时可将其翻转安装,以使原吸入区变为排出区而继续使用。3.拆装 注意工作表面清洁,工作时油液应很好过滤。4.叶片在叶槽中的间隙太大会使漏泄增加,太小则叶片不能自由伸缩,会导致工作失常。5.叶片泵的轴向间隙 对ηv影响很大。1)小型泵-0.015~0.03mm2)中型泵-0.02~0.045mm6.油液的温度和粘度 一般不宜超过55℃,粘度要求在17~37mm2/s之间。粘度太大则吸油困难;粘度太小则漏泄严重。作为泵产品,叶片泵更多地指滑片泵。只要你有兴趣在百度搜索发现,叶片泵几乎全部指滑片泵。
