Description

一种抗汽蚀水泵叶轮
技术领域
本发明涉及水泵配件领域，具体涉及一种抗汽蚀水泵叶轮。
背景技术
目前市场上针对大冷却水泵的叶轮叶片均设计为直线型，但直线性的叶片存在流量小、扬程低等缺点，不能满足各种应用需求。
另外，市场上的叶轮表面均采用镀锌处理，但在叶轮在高速运转中，表面镀锌层易脱落，叶轮易生锈，降低了使用寿命 ；表面镀锌层脱落后在冷却液中，使水封摩擦副早期磨损，水封漏水，影响使用寿命。
发明内容
本发明主要解决的技术问题是提供一种抗汽蚀水泵用叶轮，能够提高扬程，叶轮不易生锈，具有腐蚀后自动报警装置。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种抗汽蚀水泵叶轮，包括：叶片、固定叶片的轮轴以及固定轴孔，所述固定轴孔于所述轮轴的中央，叶片均布于固定轴孔外围的轮毂面上，所述叶片、轮轴以及固定轴孔表面均设有抗汽蚀锌镍层，其中，叶片上的抗汽蚀锌镍层下埋设有感应层，所述感应层与一监控装置连接。
作为优选，所述感应层为感应薄片，其厚度为1-2mm。
作为优选，所述抗汽蚀锌镍层为 4-5mm。
本发明的有益效果是：本发明抗汽蚀水泵用叶轮效率高、流量大、扬程高，叶轮在高速运转中，表面锌镍层不易脱落，叶轮不易生锈，当叶片被汽蚀后，通过感应层感应，并监控报警，延长了使用寿命；由于表面镀层不脱落，冷却液的清洁度好，水封摩擦副磨损正常，能相对延长使用寿命。
附图说明
图1为本发明的结构示意图。
具体实施方式
一种抗汽蚀水泵叶轮，包括叶片、固定叶片的轮轴以及固定轴孔，所述固定轴孔于所述轮轴的中央，叶片均布于固定轴孔外围的轮毂面上，所述叶片、轮轴以及固定轴孔表面均设有抗汽蚀锌镍层，其中，叶片上的抗汽蚀锌镍层下埋设有感应层，所述感应层与一监控装置连接；所述感应层为感应薄片，其厚度为1-2mm；所述抗汽蚀锌镍层为 4-5mm。
