Description
Technical field
The invention belongs to hydrotechnics field, more particularly to a kind of movable pump station.
Background technology
At present since China is manySewerage systemDesign standard is too low, drainability wretched insufficiency.City is improved as early as possible
City controls flood and drains flooded fields ability, it has also become Chinese Urbanization developmentThe task of top priority.Flood control draining department selects movable pump station to tackle
What flood season occurredFlood, emergency flood fighting movable pump station just plays the role of critical.
During flood season, without flood discharge capacity or the place of flood discharge capacity deficiency, particularly at the hypsography low-lying in city, ponding is more
It is more, or even non-transformer connection pumping equipment.
The suction head of pump is limited be subject to pump self character, and the datum level and the ultimate range of the water surface pumped in theory is
10m.Since some land-service roads in city are narrow, mobile pump vehicle can not reach scene of specifying, and only increase the length of pump water inlet pipe,
The resistance of water inlet certainly will so be increased, equivalent to the suction head of pump is increased, the maximum suction lift of pump may be exceeded,
Make pump cisco unity malfunction.
Continuous with liquid level reduces, and suction head is also increasing therewith, it is equally possible to which the maximum suction that can exceed pump is high
Degree, makes pump cisco unity malfunction.
With the continuous change of environment, extreme weather is more and more, and in certain areas, arid phenomenon often occurs, same right
Movable pump station proposes the requirement of higher.
The content of the invention
Stringent to water inlet suction head requirement present invention aim to solve movable pump station, the water inlet for improving pump is inhaled
Journey, so that under the conditions of in low water level and at a distance, realizes the requirement drained off floodwaters with drought resisting.
To achieve the above object, the technical scheme is that：A kind of movable pump station, including self priming pump（4）, the self-priming
