Less materials, thus saving costs.
【技术实现步骤摘要】
一种离心泵泵盖
本技术属于液体泵设备制造
,具体涉及一种离心泵泵盖。
技术介绍
离心泵是利用叶轮旋转而使水发生离心运动来工作的,水泵在启动前,必须使泵壳和吸水管内充满水,然后启动电机,使泵轴带动叶轮和水做高速旋转运动,水发生离心运动,被甩向叶轮外缘,经蜗形泵壳的流道流入水泵的压水管路。离心泵的基本构造是由六部分组成的,分别是叶轮、泵体、泵轴、轴承、密封环和填料函,现有的离心泵泵盖与外部的连接力度小,同时轴承容易发生轴向运动,造成磨损,从而影响泵盖的使用寿命。
技术实现思路
本技术旨在提供一种离心泵泵盖,与外部连接紧密,同时限制了轴承的轴向运动,磨损小,使用寿命长。按照本技术的技术方案,所述离心泵泵盖,包括盖体,盖体的中心处设有轴孔,轴孔的外壁与盖体形成泵盖,所述轴孔呈从内向外收缩的锥状;所述盖体的边缘设有定位孔并均布有一圈泵盖安装通孔,盖体的外端面设有一圈泵体安装孔;盖体的外端面贴近轴孔外壁处设有环形凹槽,环形凹槽内设有筋板;所述轴孔的外端设有密封环,轴孔外壁的端面设有密封盖安装孔,轴孔外壁的端部设有与轴孔相通的润滑液道。进一步的,所述润滑液道倾斜设置。进一步的,所述轴孔的锥角为5-7°。进一步的,所述密封盖安装孔为圆形孔,均布于轴孔外壁的端面。进一步的,所述环形凹槽的外壁为阶梯状。本技术的有益效果在于:轴孔呈从内向外收缩的锥状,限制了轴承的轴向运动,磨损小,使用寿命长;泵盖安装通孔、泵体安装孔和密封盖安装孔均为多个,外部连接紧密,结构可靠性高;润滑液道倾斜设置,更利于润滑液进出;设有环形凹槽和筋板,在不影响强度的同时减少了用材,从而节约了成本。附图说明 ...
