Description
Technical field
The present invention relates to a kind of pump, particularly a kind of vacuum turbine engine of self configuration that utilizes carries out diversion, and pump housing bottom is provided with the radially subdivision large-scale pump that singly spues of a plurality of suction inlets, also can be described as turbine parallel multiple-suction single-discharge vertical-type lifting pump.
Background technique
Large-scale elevator pump is widely used in factory, mine, urban water supply and sewerage, seawater and promotes, also can be used for power station, large hydraulic engineering, farmland discharging-irrigating etc.
The large-scale elevator pump of extensive use at present both at home and abroad has double suction middle-opening pump, one step single sucking submersible pump, mixed flow pump, axial-flow pump and vertical diagonal flow pump etc., now should be used as following some explanation with regard to above all kinds of large-scale elevator pump:
1, the double suction middle-opening pump belongs to the water pump of big flow, its necessary NPSH (NPSHR) is generally bigger, all very high because of the magna pump center line again to the footing height, so actual suction head is all very low, in order to overcome the low shortcoming of suction head, at present in use mostly taked to build the mounting type of underground pump house, the investment that has strengthened construction project thus.
2, submersible pump is the following equipment that is immersed in the medium of installing of a kind of liquid level, when it used in corrosion or temperature conditions of higher following time, as seawater or corrosivity sewage, can increase amount of maintenance because of equipment corrosion, and maintenance cost is higher relatively.
3, at present axial-flow pump, mixed flow pump and vertical diagonal flow pump promote in the engineering at big flow water and are extensive use of, because of its at big flow (10000M
3More than/the h) suct poor ability under the condition, the same with the double suction middle-opening pump self do not have suction capacity, so in use all taked to build at present the mounting type of underground pump house, strengthened land seizure, capital construction and the investment of dependent claims purpose thus yet yet.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of vacuum turbine engine of self configuration that can utilize to carry out diversion, pump housing bottom is provided with the turbine parallel multiple-suction single-discharge vertical-type lifting pump of a plurality of suction inlets, solved elevator pump waste resource, cost problem of higher when work in the prior art, and the present invention sucts the performance height, stable, the easy access maintenance.
Technological scheme of the present invention is as follows:
Comprise the pump housing and external suction pipe, at least 2 volute casings are set in the pump housing, the below of each volute casing is provided with suction port separately; Be separately installed with water pump vane in each volute casing, water pump vane is connected with motor by pump shaft; The pump housing is provided with output tube, and output tube all communicates with each volute casing; Vacuum interface is set on the output tube, and an end of vacuum interface and sucking pipe is tightly connected, and the other end of sucking pipe is connected with the vacuum turbine engine.
Described volute casing is arranged to any in two core parallel connections, the combination of multicore even number or the single-row combination of multicore.
Described suction port communicates with external suction pipe.
Described output tube is connected with at least 2 volute casings.
Described motor is arranged on the top of the pump housing.
Outside the described pump housing, the volute casing centerline is radially installed dunnage.
Working principle of the present invention is:
Well-known large flow single-stage single suction NPSH is all very big, causes it to suct vacuum height and reduces, and has therefore limited Applicable scope.The present invention selects the hydraulic model of net positive suction head the best, adopts parallel connection to be combined into a water pump, can be designed to the combination of two core parallel connections or multicore as required, has not only improved sucting vacuum height but also having enlarged flow of pump.Make it have very strong suction capacity again again with after the combination of vacuum turbine engine.
Advantageous effect of the present invention is as follows:
1, the present invention adopts the multicore parallel combination structure, has not only improved sucting vacuum height but also having enlarged flow of pump.
2, the structural type of the present invention's employing is vertical multicore combination, compact equipment, and floor space is little.
3, employing of the present invention and vacuum turbine engine combining form have had very strong suction capacity, can install more than liquid level, have broken through following install traditional the coolest of the necessary liquid level of large-scale elevator pump, have realized the revolution of installing and using more than the large-scale elevator pump liquid level.
4, the present invention installs the easy access maintenance more than liquid level.
5, the present invention can utilize the automatic diversion of turbine engine that self disposes before startup, shuts down the back and discharges vacuum automatically with the medium emptying in the equipment, has reduced the corrosion of medium to equipment thus, as seawater, corrosivity sewage, has prolonged service life of equipment.More therefore, make this equipment have in the winter time the open air and install and use, need not to be incubated the characteristics of companion's heat.
6, the present invention installs more than liquid level, has cancelled the necessary underground pump house of other pumps is installed, and has also just saved a large amount of infrastructure investments.
7, by the sea, beach area such as river bank, engineerings such as desalination of sea water, cooled with seawater need be built the dam that extends to lining, sea (river) or the caisson type pumping plant of submerged, construction investment is very big.Adopt the present invention then can save great amount of investment.
