【技术实现步骤摘要】
自冷却水泵
本技术涉及一种水泵,特别是涉及一种自冷却水泵。
技术介绍
在现有技术中,水泵有离心、轴流、混合、自吸、增压、潜水式的多种类型的水泵,通常水泵的设计为泵座、轴承室、泵壳为分体件,这样生产容易,制造简单,但因轴承转动发热后,空气不能将轴承室的热量散发掉,限定了水泵的连续工作时间和最高转速,影响了水泵功能的最大发挥,从而影响了设备整体功能。
技术实现思路
有鉴于此,本技术的主要目的在于提供一种自冷却水泵,通过本技术方案,将泵座、轴承室、泵壳设计为一体,使进水腔包围轴承室腔,通过水流将轴承室产生的热量带出形成自动冷却,从而可实现连续高速运行,延长使用寿命的目的。为了达到上述目的,本技术的技术方案是这样实现的:一种自冷却水泵,包括泵壳、蜗线腔出水道和叶轮,所述蜗线腔出水道设置在泵壳后端上,叶轮设置在蜗线腔出水道中,还包括泵座、水泵轴前支承、水泵轴后支承和水泵轴,所述泵座底部与泵壳内壁下部连为一体,泵座上部向上凸起,泵座前端沿径向与泵壳前端内壁连为一体,泵壳中间顶部设置有入水口,泵壳后部中心位置设置有蜗线腔入水口,所述水泵轴前支承和水泵轴后支承分别设置在泵座的前部和中部中,水泵轴分别设置在水泵轴前支承和水泵轴后支承中,水泵轴的尾部与叶轮相连。作为进一步的技术方案,所述泵座前部向上凸起与所对应的泵壳上部内壁相连为一体,泵座中水泵轴前支承和水泵轴后支承之间设置有呈环形空间的润滑室,泵壳前部上方和泵壳前部下方分别设置有注油孔和放油孔,注油孔和放油孔经泵座与润滑室相连通,在泵壳的注油孔和放油孔上分别设置有注油封和放油封。作为进一步的技术方案,所述水泵轴后支承后部的泵座上设 ...
