Abstract

本实用新型涉及一种能够定位泵轴结构的水泵进出水段，属水泵部件制造领域。它包括水泵进出水段，水泵进出水段腔体中心设有泵轴定位孔槽。优点：从根本上解决了背景技术存在的泵轴悬空而造成的泵轴摆动的不足，确保了泵轴的同轴度，确保了水泵的正常工作。

Description

具有泵轴定位结构的水泵进出水段
技术领域：
本实用新型涉及一种能够定位泵轴结构的水泵进出水段，属水泵部件制造领域。
背景技术：
授权公告号为CN2527757、名称“冲压不锈钢多级泵”，该泵中的进出水段的内腔没有泵轴结构，其不足之处：由于泵轴下端为悬空，位于泵轴上的多级叶轮在电机轴、泵轴的带动下，其旋转的同轴度根本无法保证，严重地影响水泵的正常工作。
发明内容：
设计目的：避免背景技术中的不足之处，设计一种既能够确保泵轴同轴度，又能够定位泵轴下端的进出水段。
设计方案：为了实现上述设计目的，在水泵进出水段的内腔内设计有泵轴下端定位孔槽，该孔槽内镶有滑动轴承，泵轴的下端与滑动轴承相匹配，使泵轴的上、下两端实现了定位旋转，避免了背景技术存在的泵轴下端悬空而产生的泵轴摆动的不足。其技术方案：具有泵轴定位结构的水泵进出水段，它包括水泵进出水段(1)，水泵进出水段腔体中心设有泵轴定位孔槽(2)。
本实用新型与背景技术相比，从根本上解决了背景技术存在的泵轴悬空而造成的泵轴摆动的不足，确保了泵轴的同轴度，确保了水泵的正常工作。
附图说明：
图1是具有泵轴定位结构的水泵进出水段的剖视结构示意图。
具体实施方式：
实施例1：参照附图1。具有泵轴定位结构的水泵进出水段，它包括水泵进出水段1，水泵进出水段腔体中心设有泵轴定位孔槽2且采用精密铸钢工艺铸造加工成型。泵轴定位孔槽2镶有滑动轴承3，泵轴4下端与滑动轴承3相匹配、上端通过联轴器与电机轴联接。
需要理解到的是：上述实施例虽然对本实用新型作了比较详细的说明，但是这些说明只是对本实用新型说明性的，而不是对本实用新型的限制，任何不超出本实用新型实质精神内的发明创造，均落入本实用新型的保护范围内。
