Description

一种容积泵
技术领域
本发明涉及一种流体输送装置，特别涉及一种容积泵。
背景技术
现有技术的容积式泵中有一种叶片泵，其结构主要包括有泵壳，泵壳内 设有圆柱形的泵腔，泵腔内偏心设置有转子，转子上径向开设有若干槽，在 所述槽中一一对应插装有叶片，泵壳的一侧设有进油口，泵壳的另一侧设有 出油口，泵壳两端设有端盖，叶片与端盖相配合设置。其工作时，转子转动， 离心力使叶片甩出，叶片、泵壳和转子之间形成一个容积变化的空间，通过 进油口和出油口位置的设置，使进油口朝向容积逐渐变大的空间，出油口朝 向容积逐渐变小的空间，可实现从一侧吸油，另一侧排油。其不足之处在于： 该泵的叶片质量小，需要较高转速才能使叶片与泵壳内腔之间形成良好的密 封，叶片与泵壳之间容易过度磨损；此外，叶片两端、顶部形成多处密封面， 容易造成密封不良而影响泵的效率。
发明内容
本发明的目的是提供一种容积泵，使其内部泄漏小、运动件之间磨损 小。
本发明的目的是这样实现的：一种容积泵，包括泵壳，泵壳内设有圆 柱形的泵腔，泵腔内偏心设置有转子；泵壳的一侧设有连通泵腔的进油口， 所述转子上周向均匀开设有若干径向孔，径向孔中配合插入有柱塞，柱塞朝 向泵腔的端部设有滚轮，转子上设有与径向孔连通的轴向出油孔，所述柱塞 上设有轴向通孔，轴向通孔中设有单向阀，轴向出油孔中设有半圆柱形的配 油轴，转子转动时，配油轴遮挡在所述径向孔容积逐渐增大的一侧。
该装置工作时，转子单向转动，带动柱塞作圆周运动，离心力驱使柱塞 向外运动，滚轮贴靠在泵腔内壁上，柱塞运动时，在部分区域内会向外伸出， 此时，单向阀开启，同时配油轴遮挡径向孔内侧，泵壳内的油向径向孔内注 油，柱塞继续运动，柱塞径向向径向孔内侧移动，单向阀关闭，同时，径向 孔与轴向出油孔接通，可通过轴向出油孔向外排油；如此，循环运动，可不 断从进油口进油再从轴向出油孔排油。该装置运动平稳，进出油连续顺畅， 内部泄漏小，滚轮在泵壳能能得到良好的润滑，其噪音小、使用可靠；该装 置可制成小流量的油泵，可作为柴油机、汽油机等原动机的轴带油泵使用， 可显著减小运动噪音。
为减小泵腔内的磨损，所述泵腔内壁上设有耐磨衬管。耐磨衬管可以更 换，保证其工作可靠，使用寿命长。
为使得滚轮越过进油口对应的开口位置时，能无阻碍地通过，所述耐磨 衬管与进油口对应位置设有若干通油孔。也可以使滚轮直径远大于进油口的 孔径。
作为本发明的改进，所述单向阀包括设置经弹簧推挤安装在阀座内的阀 球，弹簧的另一端设有带有通孔的阀座，阀座螺纹连接在所述径向孔中。该 阀结构简单，制造安装方便。
附图说明

其中，1泵壳，2转子，3柱塞，4滚轮，5单向阀，6耐磨衬管，7配油 轴，8轴向出油孔，9通油孔，10进油口，11销轴。
具体实施方式
