Embodiment Construction

[0013] In the present invention, a vacuum pump is added on the top of the siphon pipe, and a valve is installed at the outlet of the water delivery pipe (see accompanying drawing for details). The siphon and water pipe are determined by hydraulic calculation according to the water level difference and the required water intake. The size of the vacuum pump is determined according to the total volume above the water surface of the siphon and water pipe and the running time of the vacuum pump.

[0014] When starting the siphon, first use the vacuum pump to exhaust the air in the pipeline, stop the vacuum pump after the water level rises and fill the pipeline, and then open the valve at the outlet to start the siphon to take water. When air accumulates at the top of the siphon pipe during operation, turn on the vacuum pump to suck out the accumulated air so that the siphon water intake pipe can maintain continuous and stable operation and never stop flowing. It solves the problems...

Abstract

The invention relates to the siphon water intaking technology, in particular to a vacuum pump-assisted siphon water intaking device and a method. The device comprises a siphon pipe, a water duct, a vacuum pump communicated with the top part of the siphon pipe, and a valve arranged at the water outlet end of the water duct. The method is implemented as follows: at the starting stage, air in the siphon pipe and the water duct is exhausted by the vacuum pump, the water level rises to tank up the siphon pipe and the water duct, the vacuum pump is stopped, and the valve at the water outlet end of the water duct is started to perform siphon water intake; and at the running stage, when air gathers in the siphon pipe, the vacuum pump is started to exhaust the gathered air so as to ensure continuous and stable operation of a siphon water intaking pipe without water interruption. The invention solves the problems of difficult starting and instable operation of siphon water intaking of a large pipeline, improves the normal suction head of the siphon pipe, and saves engineering cost and operation power consumption respectively by over 90% compared with the method of establishing a pump station.

Description

technical field [0001] The invention relates to a siphon water intake technology, in particular to a vacuum pump assisted siphon water intake device and method. Background technique [0002] Common water intake devices include three types: pump water intake, artesian water intake, and siphon water intake. Water pumps have a wide range of applications, but consume a lot of energy; self-flowing water diversion does not consume energy, but it is only suitable for diverting water from high places to low places, and the places that flow through the way must be lower than a certain height of the water inlet, which requires high terrain; Siphon water intake is also to divert water from a high place to a low place, but it can cross the high ground without energy consumption, but it is troublesome to start and the operation is mostly unstable. It is generally believed that the siphon height of siphon water intake must be less than 7 meters. In engineering practice, projects with a s...
