Description
Technical field
The invention belongs to the pump technology field, specifically, particularly a kind ofly use suction pump by speedily carrying out rescue work of driving of excavator.
Background technique
At present, at the scenes of speedily carrying out rescue work such as flood fighting flood control, colliery are permeable, need fast ponding is extracted out from the tunnel, with the rescue trapped personnel, reduce property loss.Existing suction pump is by motor driving, and power is little, and pump duty is little, and can not satisfy speedily carries out rescue work is pressed for time, the demand that the pump water yield is large.The on-the-spot non-transformer of speedily carrying out rescue work that has causes suction pump can not afford; Although some places have power supply, power supply is distant, and the time that the wiring of connecting up like this spends is longer, can incur loss through delay the best opportunity of speedily carrying out rescue work greatly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of suction pump that is driven, be can be used in rapid rescue by excavator.
technological scheme of the present invention is as follows: a kind ofly use suction pump by speedily carrying out rescue work of driving of excavator, comprise the pump housing (1), the inside of this pump housing (1) has main chamber (1-1), be provided with the water outlet (1-2) that communicates with main chamber (1-1) on all sidewalls of the pump housing (1), the bottom of the described pump housing (1) is provided with the chamber of drawing water (1-3), this chamber of drawing water (1-3) is positioned at the below of main chamber (1-1), and be connected with main chamber (1-1) by water channel (1-4), have lower water intake (1-5) on the diapire in the described chamber of drawing water (1-3), draw water and have the side water intake (1-6) that distributes by even circumferential on all sidewalls in chamber (1-3), the upper end of the described pump housing (1) fixes by supporting base (2) and connecting base (3), oil hydraulic motor (4) is installed at top at connecting base (3), the output shaft of this oil hydraulic motor (4) stretches into downwards in connecting base (3), and be connected with the upper end of pump main shaft (5), described pump main shaft (5) is supported by bearing, the lower end of this pump main shaft (5) is passed in the main chamber (1-1) that supporting base (2) stretches into the pump housing (1), end installation helical blade (6) in described pump main shaft (5) lower end, this helical blade (6) is positioned at main chamber (1-1), be fixed with two otic placodes that are parallel to each other (7) in the outside of described connecting base (3), connect the first scraper bowl axle (8) between the upper end of two otic placodes (7), this the first scraper bowl axle (8) is positioned at the side of oil hydraulic motor (4), connect the second scraper bowl axle (8 ') between the lower end of two otic placodes (7), this second scraper bowl axle (8 ') is positioned at the oblique below of the first scraper bowl axle (8).
