To describe the present invention more fully with reference to following accompanying drawing now, demonstrate the preferred embodiment that does not limit this invention of the present invention in the accompanying drawing.
Fig. 1 shows a kind of according to flushingpump of the present invention to Figure 10.Flushingpump according to the present invention comprises motor (motor) 10, impeller 20, pump case 30, sealed base 40, shaft seal 50 and terminal cap 60.
In more detail; Packaging vehicle flushingpump of the present invention comprises: the pump case 30 that is provided with pump chamber 36 and motor chamber 38 integratedly; Embedding in this motor chamber 38 has motor 10 and is positioned at pump chamber 36 tops; The impeller 20 that is wherein rotated by motor 10 is installed in pump chamber 36 inside, and the inlet opening 32 that is communicated with can,douche is formed on the bottom intermediate portion of pump chamber 36, is formed on the side of pump chamber 36 through its exit orifice 34 of discharging washing solution; Sealed base, its pump chamber 36 tops that are inserted into pump case 30 are to separate pump chamber 36 and motor chamber 38; Shaft seal, it is inserted in the sealed base 40 to keep being exposed to the water-stop state of the motor 10 in the pump chamber 36; Terminal cap, it flexibly is attached to the top of pump case 30, is inserted with motor 10, impeller 20, sealed base and shaft seal 50 in this pump case 30.
Mark 70 in the accompanying drawing is electromagnetism cancellers, the 72nd, and terminal lead, the 80th, wherein be inserted with the ejector block of the flexible pipe that is connected to flooding nozzle, and 82 is diaphragms.
Different with traditional pump case, pump case 30 be characterised in that on the structure through the state that is interconnected with pump chamber 36 and motor chamber 38 form pump case 30 and within it portion form pump chamber 36 and motor chamber.That is to say that the bottom of pump case 30 is closed, and the top of pump case 30 is opened wide, and had roughly cylindric cup-shapedly, and pump chamber 36 and motor chamber 38 are provided in the upper and lower of pump case 30 respectively.
Pump chamber 36 form broad at an upper portion thereof and form in its underpart narrower, to be used for that the impeller 20 that is rotated by motor 10 is installed to its inside.The inlet opening 32 that is communicated with can,douche is formed on the bottom intermediate portion of pump chamber 36, and is formed on the side of pump chamber 36 through the exit orifice 34 of its discharging washing solution.Washing solution is discharged from through exit orifice 34 under the action of centrifugal force that rotation produced by impeller 20.
Be formed with the first claw 37a that embeds sealed base 40 and the second claw 37b that closely contact with the water seal O shape ring 42 in the outside that is inserted into sealed base 40 around the upper periphery of pump chamber 36.Motor chamber 38 is formed by same diameter up to the upper end of motor chamber 30 on the second claw 37b.
Sealed base 40 is spatially isolated pump chamber 36 and motor chamber 38.The outside of sealed base 40 be formed with respectively with the inner space that is formed on pump case 30 in the first claw 37a and the corresponding first outer radius portion 41a and the second outer radius portion 41b of the second claw 37b.Form the O shape annular groove 43 that wherein is inserted with water seal O shape ring 42 along the border between the first outer radius portion 41a and the second outer radius portion 41b.
Through hole 44 is formed on the core of sealed base 40.Shaft seal 50 is inserted in the through hole 44.The axle 12 of motor 10 can insert rotationally and keep the water-stop state simultaneously, and exposes from the side of pump chamber 36.Impeller 20 axially is attached to axle 12.
Shown in Fig. 1, Fig. 9 and Figure 10; In order under the situation that does not have independent instrument, terminal cap 60 to be bonded to pump case 30; Periphery at the top of pump case 30 forms capured keystroke pawl 31, and is formed for catching that this catches claw 31 catches groove 61 at the internal surface of terminal cap 60.On pump case 30 and terminal cap 60, form anti-rotation groove 33 and anti-rotation projection 63 respectively, rotate to prevent the terminal cap 60 that is bonded to pump case 30.
As shown in Figure 6, be formed with vent h and flow into motor chamber 38 neutralizations in the bottom of pump case 30 from motor chamber 38 outflows to be used for ambient air.Said vent h does not influence pump chamber 36; But as the path that motor chamber 38 is connected to the outside; Make ambient air flow out to the outside through motor chamber 38 even make motor 10 not drive; And especially when motor 10 rotates and makes motor chamber 38 overheated by the heat that motor 10 produces, prevent the overheated of motor 10 through the convection current that utilizes ambient air.
A kind of method that is used for assembling according to flushingpump as shown in Figure 1 of the present invention is: in order impeller 20, sealed base 40 and motor 10 are inserted into pump case 30; And assemble to accomplish at the top that terminal cap 60 flexibly is bonded to pump case 30, thereby under the situation unlike the complicated and time-consuming process of traditional welding process that kind, assemble flushingpump apace by the operator scene.
In addition, the present invention has formed the pump chamber 36 that is integrated into pump case with the one mode, and pump chamber 36 separates through sealed base 40 and shaft seal 50 and motor chamber 38 and keep the water-stop state, thereby has improved reliability of products.
The invention provides in pump case itself, to be provided with and isolate each other to keep the pump chamber and the motor chamber of water-stop state through sealed base.Through inserting impeller, sealed base and motor in order, and at last terminal cap flexibly is attached to the assembling of accomplishing flushingpump on the top of pump case.Therefore; Can increase productivity; This is because can be by operator's assembled on site flushingpump under the situation of such complicated and time-consuming technology unlike traditional welding process; And can realize improving the advantageous effects of reliability, this is because through pump chamber being integrated in the pump case and keeping the water-stop state through sealed base and shaft seal isolation pump chamber and motor chamber.
