The utility model provides a water encapsulation device for a water drainage pump, including a water pump, a circulating water pump and a return pipe; the water tank is placed on the right horizontal plane of the main body of the pump, and the sealing cavity connected with the front end of the pump is connected through the water sealing pipe. The setting of the water sealing pipe and the defoaming pipe of the utility model keeps the position of the water sealing pipe and the sealing chamber under pressure all the time, guarantees the water sealing effect in the sealing chamber, and the top part of the bending part of the left end of the water sealing pipe is a downward concave bending pipe-like structure, and the downward fixing of the downward concave bending pipe-like structure of the water sealing pipe is provided with a drainage pipe, and a ball valve is arranged on the drainage pipe, which is easy to produce in the pipe. Bubbles, which in turn cause bubbles to move into the sealing chamber, destroy the seal of the feed pump, and the settings of the defoamer can just prevent bubbles from moving into the sealing chamber. When bubbles are generated in the water seal tube, bubbles will converge at the top of the low concave of the defoamer tube, and the ball valve under it can be opened to drain the bubbles.
【技术实现步骤摘要】
给水排水泵的水封装置
本技术属于水泵设备
,更具体地说,特别涉及给水排水泵的水封装置。
技术介绍
在热电厂给水泵的生产作业中,给水泵的驱动端和自由端均需密封水密封,以防止高压高温水从泵内向外泄漏,从低压侧漏入空气,目前普遍采用主凝结水作为密封水水源。基于上述,本专利技术人发现,现有的给水泵水封装置在使用时,首先因为水封管的特殊性,导致在长期使用过程中易产生气泡集聚,从而易引发气蚀,对水泵造成损害,此外,由于热电厂中给水泵始终处于高温状态,致使水封水温度也升高,而一般水封水都处于静止状态,难以进行冷却换热。于是,有鉴于此,针对现有的结构及缺失予以研究改良,提供给水排水泵的水封装置,以期达到更具有更加实用价值性的目的。
