Problems solved by technology

However, it does not give a relatively perfect design formula, which brings a lot of inconvenience to the construction of the pumping station
The Chinese patent No. 201420795367.2 discloses a siphon outlet channel with excellent hydraulic performance, which only provides a design method, which reduces the hydraulic loss of the outlet channel to a certain extent, but it is not systematically perfect design formula

Abstract

The invention belongs to the application field of a pump station and particularly relates to a design method for a siphon outlet passage. The siphon outlet passage is designed mainly for the pump station. The hydraulic loss of the outlet passage is lowered by controlling main related parameters such as a diffusion section, a water outlet bending pipe section, an ascending section, a hump section, a declining section, an outlet section and the like of the outlet passage, so that the operational stability, efficiency and economy of the pump station are improved, and the maintenance period of the pump station can be prolonged. In addition, the design method also can be combined with modern equipment to enable parametrization design to be possible.

Description

technical field [0001] The invention belongs to the application field related to pumping stations, in particular to a design method of a siphon type water outlet channel. Background technique [0002] Generally speaking, vertical pumps are used in large pumping stations. Therefore, the flow channel from the outlet of the pump guide vane to the outlet pool, that is, the outlet flow channel is essential for it. Generally, the form of the water outlet channel can be divided into siphon type, straight pipe type, two-way water outlet type, knee-bending type, cat's back type, etc. [0003] The siphon phenomenon means that if an elbow is filled with water and then two different water levels are connected, the water flow will automatically flow from the high water level to the low water level. The siphon outlet channel is a curved outlet channel that uses the siphon principle, because it can cross the embankment without any impact on the safety of the embankment, and its way of cut...
