Abstract
The utility model discloses an infusion pump, which comprises a pump case, a pump cavity in the pump case, a main flow passage with an inlet and an outlet, and vanes arranged in the pump cavity, wherein the main flow passage is communicated with the pump cavity. The utility model is characterized in that a bypass flow passage is arranged in the pump case; the bypass flow passage passes round the pump cavity and is communicated with the inlet and the outlet; a triple valve is arranged at a meeting point of the two flow passages in the outlet position; the eccentric position inside the pump cavity is provided with a barrel shaft, and the diameter of the barrel shaft is smaller than that of the pump cavity; a power shaft penetrates through the barrel shaft and is fixedly connected with the barrel shaft; one end of the power shaft is connected with the pump case by a bearing, and the other end extends out of the pump case; the vanes are at least a pair of rectangular plates; the rectangular plates are movably inserted in opposite through slots which are arranged on the periphery of the barrel shaft; the rectangular plates in each pair are connected with each other by a pressure spring. The utility model has the advantages that when the infused liquid surface is higher than a liquid outlet, the infused liquid is discharged from the liquid outlet under the action of atmospheric pressure by using siphon principle; the utility model not only saves the energy, but also does not have pulse flow phenomenon.
Description
Technical field
The utility model relates to a kind of liquid sorption pump of pumping liquid.
Background technique
The liquid sorption pump that is used for liquid suction at present has driven by shaking and electronic two kinds, but existing deficiency is still to adopt motivational drive just can reach the purpose of pumping liquid when the liquid level that is sucked liquid is higher than liquid outlet, causes the waste of manpower, the energy.And liquid outlet flow rate of liquid instability, the liquid that is drawn out of has the effect of Fluid Pulsation phenomenon, easily causes the splash of liquid, and especially when suction was corrosive liquid, the splash phenomenon was very big to environment, personnel's harm.
Summary of the invention
The purpose of this utility model provides a kind of liquid sorption pump that power gets final product pumping liquid that need not when the liquid level that is sucked liquid is higher than liquid outlet.
For achieving the above object, the utility model can be taked following technical proposals:
Liquid sorption pump described in the utility model, comprise pump case, be opened in the pump chamber in the described pump case, with have sprue import and export, that communicate with described pump chamber, and be arranged on blade in the pump chamber, offer a bypass runner in described pump case, described bypass runner is walked around pump chamber and is connected with described import and export; Be provided with three-way valve being positioned at outlet port two runner joints; The eccentric tube axle of a diameter less than the pump chamber diameter that be provided with in pump chamber, line shaft run through described tube axle and are connected mutually with the tube axle; One end of described line shaft links to each other with pump case by bearing, and the other end extends outside the pump case; Described blade is at least one pair of rectangular plate, and described rectangular plate activity is inserted in and is opened in vertically in the groove relative on the tube axle side face; Link by pressure spring between every pair of rectangular plate.
The length of described rectangular plate is equal to or greater than the length of described tube axle.
Advantage of the present utility model just is to be opened in the bypass runner in the pump case, and is set in place in the three-way valve of outlet port sprue and bypass runner intersection.Make when being sucked liquid level and being higher than liquid outlet, by three-way valve the bypass runner is closed, the rotating power axle drive blade with the gas in sprue, the bypass runner after liquid outlet is discharged, open liquid outlet, utilize siphon principle, be sucked liquid and under the atmospheric pressure effect, discharge, not only saved the energy from liquid outlet, and flow of fluid is stable, the no pulse phenomenon that flows; And when being sucked liquid level and being lower than liquid outlet, by three-way valve the bypass runner is closed, realize the pumping liquid purpose by power, a pump is used more.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
As shown in the figure, liquid sorption pump described in the utility model, comprise pump case 1, be opened in the pump chamber 2 in the described pump case 1, import and export sprue 53,4, that communicate with described pump chamber 2 with having, and be arranged on blade in the pump chamber 2, and in pump case 1, offering a bypass runner 6, described bypass runner 6 is walked around pump chamber 2 and is connected with described import and export 3,4; Be provided with three-way valve 7 being positioned at outlet 4 places two runner joints; The eccentric diameter that is provided with runs through described tube axle 8 less than 8, one line shafts 9 of tube axle of pump chamber 2 diameters and is connected mutually with tube axle 8 in pump chamber 2; One end of described line shaft 9 links to each other with pump case 1 by bearing, and the other end extends outside the pump case 1; Described blade is a pair of rectangular plate 10, and described rectangular plate 10 activities are inserted in and are opened in vertically in the groove relative on tube axle 8 side faces; Link by pressure spring 11 between the rectangular plate 10.The length of rectangular plate 10 equals the length of tube axle 8.
