船用卧式离心泵内置降温式轴承座
本技术涉及一种轴承座,具体地讲,本技术涉及一种水泵内置轴承座,特别是一种船用卧式离心泵内置降温式轴承座。
技术介绍
卧式离心泵是一种常见的通用型泵产品,其市场保有量很大。卧式离心泵由轴承座支承泵轴,泵轴借助联轴器直联动力机械,此种常规传动结构十分简单,在陆地上运行很可靠。可是,应用到船舶上的卧式离心泵仍然沿用现有技术的轴承座,则使用寿命极短,究其原因是船用卧式离心泵安置在船舱中,空间相对狭窄,环境温度高,再加上自身散热条件差,持续运行易产生高温。轴承座升温一方面促成内置润滑油变稀,甚至汽化,另一方面加速密封件老化,从而造成内置的润滑油泄漏。润滑油流失结果是配套的轴承失去润滑条件而损坏,泵不能运行,对于船舶这种浮动的载体,航行中出现此类问题很难及时得到维修,由此影响配套船舶的正常航行。
技术实现思路
本技术主要针对现有技术的轴承座降温条件差的问题,提出一种结构合理、制作容易,降温效果明显的船用卧式离心泵内置降温式轴承座。本技术通过下述技术方案实现技术目标。船用卧式离心泵内置降温式轴承座,它包括前轴承孔、储油腔、回油槽、内水道、后轴承孔和肋片。所述前轴承孔和后轴承孔同轴相间排列,两只轴承孔底边分别设有轴向回油槽,在前轴承孔与后轴承孔之间设有向下凹入的储油腔。其特征在于:所述后轴承孔和储油腔的结合段底部外壁上设1~3道与水平线相平行且长度方向与轴线垂直的内水道,内水道两端面分别设有进水接口和出水接口,相邻内水道借助外接管道形成串通的内水冷结构。所述前轴承孔和储油腔上部外壁由均布且径向伸出的肋片组成散热结构。作为进一步改进方案,所述肋片等长 ...
