Abstract

本实用新型公开了一种用于液体输送、增压的紧凑型卧式离心泵。其主要由泵体、叶轮、泵盖、电机和泵座等组成,特点在于电机的轴与泵盖轴向定位连接后,直接通过键与叶轮相连。本实用新型结构紧凑,同轴度好,磨损小、噪声低、占地面积小、转动阻力小,转动扭矩小,且无漏油、漏水现象,减少了加工、装配、整修等工序,提高了泵的生产效率。

Description

紧凑型卧式离心泵
本实用新型涉及一种液体输送、增压的机械电器设备,特别涉及一种卧式单级离心泵。
目前的卧式单级单吸离心泵是靠电机高速旋转,通过联轴器带动泵的叶轮同速旋转,使液体从叶轮轴心区流入叶轮外沿边缘区加速离心而甩出。但因此类泵的电机轴与泵轴通过联轴器连接带动而同速旋转,故存在着结构松散,占地面积大,同轴度差,噪声大,电机轴、泵轴磨损严重等诸多不足。同时,以前此类泵均采用填料密封,还存在着易泄漏,泵房易积水,泵轴润滑系统易漏油,污染环境的缺失。上述种种不足,长久以来一直未能得到有效解决。
本实用新型的目的在于:提供一种能有效克服上述缺陷,占地面积小,结构合理的紧凑型卧式离心泵。
本实用新型的技术方案为:一种紧凑型卧式离心泵,主要由泵体、叶轮、泵盖、电机和泵座等组成,其特点在于:电机的轴与泵盖轴向定位连接后,直接通过键与叶轮相连,同时采用机械密封。
由于采用上述方案,不难得出如下结论:本实用新型结构紧凑,同轴度好,磨损小,噪声低,占地面积小,转动阻力小,转动扭矩小,大大提高了泵的性能参数。且无漏油漏水现象,故泵房环境清洁,减少了加工,装配、速修等工序,提高了泵的生产效率。
下面结合附图和实施例对本实用新型作进一步详细描述。
附图为本实用新型的结构示意图。
如图所示,一种紧凑型卧式离心泵,由泵体1、叶轮2、泵盖7、电机8和泵座9等组成,泵盖7后端由螺栓、螺母连接紧固于电机8端面,泵盖7前端由螺栓、螺母与泵体1连接紧固。电机8的轴5上紧配挡水圈6后,再紧配机械密封4,并与泵盖7轴向定位和紧配密封,再通过键安装叶轮2,之后再固定泵座9上,其中机械密封4定位用叶轮螺母3紧固。
