Motor is electrically connected with heat protector.
Beneficial effect of the present invention: the electric motor temperature reduction of water pump of the present invention is realized by the flowing water of electrical machinery cover outside, thus make motor be in low-temperature condition for a long time, makes motor not fragile, add the working life of motor; And electrical machinery cover by motor seal wherein, short circuit of can not intaking when motor is used under water, can not burn out motor, uses and does not have narrow limitation, and the part of water process adopts stainless steel to make or adopt nylon material to make, and guarantees the safety at water source.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The water pump of a kind of land as shown in Figure 1 and under water double-purpose, it should be noted that, comprise shell 1, front cover 2 and rear end cover 3 is connected with respectively at the two end part of shell 1, what between two end cap, be positioned at shell 1 is externally connected to pull bar 4, two end cap and shell are locked by nut by pull bar 4 two ends, an airtight electrical machinery cover 5 is provided with in shell 1, motor 6 is installed in electrical machinery cover 5, the gap 7 flow through for liquid is provided with between electrical machinery cover 5 and shell 1, a screw blade 8 is provided with at the output terminal of motor 6, a screw rod gum cover 9 is coordinated at the front end of screw blade 8, screw rod gum cover 9 is pressed on a manger board 11 by a pressing plate 10, manger board 11 is connected with shell 1, front cover 2 is provided with water intake 12, at water intake 12 place, one one-way valve 13 is installed, rear end cover 3 is provided with water outlet 14, the power line sealing of described motor 6 runs through electrical machinery cover 5 and rear end cover 3.
It should be noted that further and be provided with multiple projection 15 at the inwall of rear end cover 3, electrical machinery cover 5 is provided with the positioning groove 16 with projection 15 clamping.Projection 15 is that limiting motor cover 5 rotates with the effect of positioning groove 16.
It should be noted that described shell 1 and electrical machinery cover 5 are stainless steel and make further.
It should be noted that described front cover 2 and rear end cover 3 are resistant to elevated temperatures nylon material and make further.
It should be noted that further to divide at motor output and be provided with stuffing box bearing 17 between electrical machinery cover 5.
It should be noted that further and be equipped with at the inwall of described front cover 2 and described rear end cover 3 annular groove 19 matched with shell 1, the two ends of shell 1 are connected in the annular groove 19 of front cover 2 and rear end cover 3 respectively, are equipped with O-ring seal 18 at the inner bottom part of two annular grooves 19.
