Description

一种渣浆泵叶轮与护板配合结构
技术领域
本实用新型涉及一种对渣浆泵叶轮与护板配合结构的改进，属于渣浆泵技术领域。
背景技术
从上世纪80年代至今，渣浆泵的叶轮与护板一直都是沿用锥面配合结构，其加工的精度低、间隙大、易磨损。因为在加工叶轮与护板时，端面加工完后才能重新对刀车削叶轮与护板的配合锥面，这时误差产生，使得锥面的配合误差大，间隙也较大，磨损快。
发明内容
本实用新型针对上述现有技术存在的技术问题，提供一种新型渣浆泵叶轮与护板配合结构，有效降低介质对叶轮进口处的磨蚀，减小介质经由叶轮与护板之间间隙的泄漏量，保证渣浆泵高效运行，并使整机安全、高效的长时间运行。
为实现上述目的，本实用新型采用的技术方案是：一种渣浆泵叶轮与护板配合结构，包括叶轮、护板，其特征在于：叶轮与护板的配合面采用平面结构。
本实用新型的优点是：本实用新型提供一种渣浆泵叶轮与护板平面配合结构，加工叶轮与护板的端面时一刀就可以车削过去，避免二次加工，保障了加工精度，平面配合结构简单，加工更容易，降低了加工成本。此结构可有效降低介质对叶轮进口处的磨蚀，减小介质经由叶轮与护板之间间隙的泄漏量，保证渣浆泵高效运行，并使整机安全、高效的长时间运行、性价比高。
附图说明
图1是现有叶轮与护板锥面配合结构示意图。
图2是本实用新型的结构示意图。
具体实施方式
下面结构附图对本实用新型做进一步描述。
如图1所示，现有渣浆泵的叶轮1与护板2配合面A处一直都是沿用锥面配合结构，其加工的精度低、间隙大、易磨损。
如图2所示，本实用新型的一种渣浆泵叶轮与护板配合结构，包括叶轮1、护板2，叶轮1与护板2的配合面A处采用平面结构，其加工一刀就可以车削完成，避免二次加工，加工更容易、更易保障精度，平面配合结构简单，加工更容易，降低了加工成本。此结构可有效降低介质对叶轮进口处的磨蚀，减小介质经由叶轮与护板之间间隙的泄漏量，保证渣浆泵高效运行，并使整机安全、高效的长时间运行、性价比高。
