【技术实现步骤摘要】
一种水泵的进水段结构
本技术涉及轻型卧式多级离心泵的领域,具体涉及一种水泵的进水段结构。
技术介绍
水泵中的出水段收集水泵中叶轮流出的液体,并将液流引向泵的出口。现有水泵的不锈钢进水段都采用铸造、车加工成型的方法,铸件与冲压焊接件相比,有以下缺点:铸造件内部组织疏松,存在气孔、夹渣、裂纹等缺陷,易导致漏水现象,而冲压用的轧制板材内部组织细化均匀、抗拉强度高、不会出现漏水现象;铸造是一个高能耗、高成本的加工方法,铸造毛坯单价是板材单价的2至3倍;铸件的成型时间较长,人工时效处理时间长,交期相比冲压件会长3-4倍时间;铸件的成型工艺对环境影响相对较大。正因为铸造件存在上述缺陷、缺点,所以现有的水泵进水段成本高、漏水风险与故障高、产品交期长。
技术实现思路
本技术的目的在于克服现有技术存在的不足,而提供一种水泵的进水段结构。本技术的目的是通过如下技术方案来完成的:这种水泵的进水段结构,主要包括进水管、进水体,所述的进水体中间设置有向上凸起的凸台,进水管为圆管状,主要包括有螺纹段和无螺纹段,螺纹段上设置有内螺纹,无螺纹段设置有环形的凹槽,无螺纹段套装在进水体的凸台并焊接固定。所述的进水体上对称设有两个孔,进水体四角设有安装孔,进水体上还设有箭头标志。所述进水管由无缝钢管经过车加工后成型,所述进水体由冷轧钢板冲压成半成品。本技术的有益效果为:本技术进水段由原来的不锈钢铸造、车加工成型更改为板材的冲压、焊接成型,有效解决裂纹、夹砂、气孔等铸造缺陷,解决了零件因成型工艺造成的水泵漏水 ...
