三台排水泵配电箱设计.doc

摘要
随着社会的发展,各种建筑也在不断地增加,排水系统的好坏会也成为决定一个建筑质量的关键因素,因此排水系统十分重要。对排水泵的控制方式有多种多样,我们需根据不同的要求采用不同的控制方式。民用建筑的排水,主要时用以排除生活污水、溢、漏水和消防废水等。
本设计排水系统采用三台排水泵,采用一备两用模式。排水系统由污水集水池,液位器、排水泵组成。正常运行时,两台主泵互为备用,高水位启泵,低水位停泵;如果一定时间内集水池中污水无法排空,第一备用泵投入运行,如发生溢流情况(如存在大量消防废水情况),则发出水位报警,同时投入第二备用泵。以此实现自动和手动控制。
关键词:一用两备、互为备用、自动控制。
Abstract
With the development of society, various buildings are constantly increasing, the drainage system will also e a key factor in determining the quality of a building, so the drainage system is very important. There are many ways to control the drainage pump, we need to use different control according to different requirements. Drainage of civil building, mainly used to exclude domestic sewage, overflow, water leakage and fire water.
The design of the drainage system using three drainage pumps, using a dual-use mode. Drainage system consists of sewage pool, liquid level, drainage ponents. Normal operation, the two main pumps are alternate, high water level Kai pump, low water level stop pump; if a certain period of time the pool of sewage can not be emptied, the first standby pump put into operation, such as the overflow situation (such as the existence of a large number Fire water situation), then issued a water level alarm, while the second standby pump. To achieve automatic and manual control.
Key words: One with two equipment, each other spare, automatic control
