Abstract
The utility model relates to a siphon intake technology, in particular to a vacuum pump-assisted siphon intake device which comprises a siphon pipe and a delivery pipe, wherein the top of the siphon pipe is communicated with a vacuum pump, and the outlet end of the delivery pipe is provided with a valve. The utility model solves the problems that large-pipe siphon intake is difficult to start and can not operate stably, raises the normal suction height of the siphon pipe and enlarges the application range of the siphon intake project. Thus, the original pumping station-dependent intake project can adopt the siphon intake mode, so that the construction cost of the pumping station can be saved. Compared with the construction of a pumping station, the vacuum pump-assisted siphon intake device in the utility model can save the construction cost and the energy consumption for operation by more than 90%.
Description
Technical field
The utility model relates to the siphon off water technology, and particularly a kind of vacuum pump is assisted the siphon off water device.
Background technique
At present common water fetching device has three kinds of water pump water intakings, artesian diversion, siphon off water.Water pump water intaking wide accommodation, but consumed energy is big; Artesian diversion is consumed energy not, but only is applicable to diversion from high to lower, and the place of flowing through must be lower than the water intake certain altitude in the way, and important and influential persons asks very high over the ground; Siphon off water also is diversion from high to lower, but can cross over the highland, does not consume energy, but starts trouble, moves scarcely stable.Theory thinks that the siphon height of siphon off water must be less than 7 meters, and in engineering practice, siphon height is also rarely found above 5 meters engineering.Siphon off water must be filled pipeline with water earlier, could start siphon then, thereby the siphon off water engineering still need be installed water pump mostly.There is the vacuum section in operating syphon tube, and the existence of vacuum is come out the air separation that is dissolved in the water.Along with the increase of degree of vacuum, the air separated can hurried increase, and the air accumulation of separating is to a certain degree making siphon destroyed and quit work.The siphonal mobile continuity of easier appearance was destroyed when degree of vacuum surpassed the 7-8 meter water column in large pipeline and syphon tube.
The model utility content
The utility model purpose provides a kind of low energy consumption, the auxiliary siphon off water device of siphon vacuum pump continuous, the increasing of siphon off water height.
Technical solutions of the utility model: a kind of vacuum pump is assisted the siphon off water device, comprises syphon tube, conduit pipe, is communicated with vacuum pump at siphonal top, is provided with valve in the waterexit end of conduit pipe.
0 meter≤siphon height h≤10 meters.
Connect vacuum gauge on the vacuum pump, the waterexit end valve of conduit pipe is a mortor operated valve.
The utility model good effect:
1, starts siphon conveniently.Existing large pipeline siphon off water engineering still will be built pumping plant as the pumping plant water intaking, relies on the water pump water intaking to fill the whole piece pipeline earlier, opens gate valve then and could start siphon.And the auxiliary siphon off water of vacuum pump directly uses vacuum pump to form vacuum, makes current fill pipeline and starts siphon, need not to install water pump.
2, stable and reliable operation.In the existing siphon off water engineering operation process, the air that syphon tube vacuum section is dissolved in the water is constantly separated and is gathered in the syphon tube top, siphonal flow is reduced gradually, until stopping.Make syphon tube recover proper functioning, must be earlier out of service, start water pump and again water is filled the whole piece pipeline, get rid of the air in the pipeline, just can restart siphon and recover water intaking, workload is big.The auxiliary siphon off water engineering of vacuum pump has been installed vacuum pump on the syphon tube top, air accumulation in the syphon tube arrives to a certain degree, when the syphon tube flow does not also obviously reduce, open the air that vacuum pump extracts the syphon tube top, syphon tube just can recover normal operation fully, can not make syphon tube out of service.
3, increased the height of siphon off water.Siphon height that it is generally acknowledged siphon off water must be less than 7 meters, and in engineering practice, siphon height is also rarely found above 5 meters engineering.The auxiliary siphon off water of vacuum pump can in time extract the air of separating, and has guaranteed the continuity of syphon tube work, at siphon height greater than 7 meters, even reach at 10 o'clock also can proper functioning.
4, save construction investment, energy efficient.The auxiliary siphon off water of vacuum pump does not rely on the starting mode of pump siphon, and the power of its vacuum pump is much smaller than pump power, thereby does not need to build pumping plant as the water pump water intaking, and required power supply capacity is low, can save the pumping plant investment significantly.In engineering operation, time that vacuum pump is opened and number of times seldom, the energy of consumption is very low, compares with the water pump water intake engineering, can save investment and operation energy consumption respectively 90%.
Description of drawings
Accompanying drawing is the utility model structural representation.
1 vacuum pump among the figure, 2 vacuum tubes, 3 syphon tubes, 4 eminence water levels, 5 lower water levels, 6 mountain regions, 7 conduit pipes, 8 valves, h are siphon height.
Embodiment
The utility model is to set up vacuum pump at siphonal top, at conduit pipe outlet port mounted valve (seeing accompanying drawing for details).Syphon tube and conduit pipe calculate by waterpower according to the water withdrawal of the water level discrepancy in elevation and needs to be determined, the size of vacuum pump according to syphon tube, more than the conduit pipe water surface the total measurement (volume) size and determine the working time of vacuum pump.
When starting siphon, with vacuum pump ducted air is exhausted earlier, water level rises and fills vacuum pump out of service behind the pipeline, opens the outlet port valve again and just can start siphon off water.When the build-up of air of syphon tube top, open vacuum pump and the air of assembling is taken away siphon off water is guaranteed hold continuously stable operation, never cutout in the running.It has solved the problem of large pipeline siphon off water startup difficulty and fluctuation of service, improved siphonal normal suction lift, enlarged the accommodation of siphon off water engineering, make the many engineerings that must build the pumping station water intaking can adopt siphon off water and save the pumping plant construction cost, compare with building pumping station, engineering cost and operation energy consumption all can be saved more than 90%.
Take the auxiliary siphon off water of vacuum pump with the obvious advantage in following situation:
1, in the big places of landform span such as cols, excavation irrigation canals and ditches diversion earthwork is very big, and it is big to the destruction of ecology to construct, and utilize water pump water intaking energy consumption big, and the auxiliary siphon off water of vacuum pump does not need earth excavation, and can save energy consumption.
2, water intaking can't the dewatering construction conduit pipe or during open channel, the auxiliary siphon off water engineering of vacuum pump is the most suitable in large-size lake, reservoir, and it does not need dewatering construction.Certain pumping station water intaking after tested, about every month power consumption 10000kwh, the remolding vacuum pump is assisted siphon off water, and power consumption only needed about 1000kwh in every month, and economic benefit is fairly obvious.
3, easy because of the auxiliary siphon off water engineering construction of vacuum pump, starting power is low, when the place of potential condition needs urgent precipitation to carry out stand-by service contentedly, as long as install pipeline, be equipped with vacuum pump and small generators and just can start big flow draining, can not be subjected to power limitations, strive for rescue time, as mine drainage rescue, flood-fighting, barrier lake draining etc.
