Abstract

The utility model discloses a submerged pump which drives by the magnetism. The utility model consists of a motor, a magnetic driving device and a two steps water pumping device. In the magnetic driving device, the magnetic steel cup is fixed and connected with the motor axis; a separating cover is positioned between the magnetic steel cup and the inner magnetic; an inner magnet is provided in the separating cover; the pressure adding blade of the two steps water pumping device is directly connected with the inner magnet; the upper water pipe is fixed with the motor shell through a pump cover and a connecting frame; and the water lead impeller is connected with the inner magnet through the main axis. When working, the motor axis drives the magnetic steel cup to rotate together; the inner magnet rotates with the magnetic steel cup with the same speed under the magnetism effect; and the pressure adding impeller is drived to rotate with the water lead impeller to reach the water pumping effect. The utility model completely avoids the erosion of the motor and the creepage problem caused by the liquid leaking of the motor axis; the utility model effectively lengthens the service life of the submerged pump and reduces the electricity creepage failure; moreover the two steps water pumping device utilizes the energy of the motor and enhances the effective power.

Description

The magnetic Ti underwater pump
Background technique
Existing Under Water Pumps, drawing liquid impeller all directly are connected with motor shaft, and when Under Water Pumps was worked, the motor shaft part that is connected with the drawing liquid impeller must be dipped in by in the drawing liquid body, and like this, some liquid can be penetrated into motor internal along motor shaft all the time.Owing to all is corrosive liquids,, shorten life-span of Under Water Pumps so can cause corrosion-damagedly to motor by drawing liquid body major part; And, because the electric action of liquid can make motor generation leak current fault, increase maintenance expenses.In addition, existing Under Water Pumps all has only an impeller, and the utilization efficiency of motor power is not high enough.
Summary of the invention
The purpose of this utility model is to provide a kind of Under Water Pumps that can avoid liquid (particularly corrosive liquids and gas) to be penetrated into motor internal by motor shaft fully and effectively improve the utilization efficiency of motor power.
The utility model is achieved in that the utility model comprises motor, magnetic transmission device and two-stage pumping device.In the magnetic transmission device, the magnet steel cup is fixedlyed connected with motor shaft, and the magnet steel cup is made by the magnetic steel material, interior empty circumferential, bottom opening.Be separation sleeve between magnet steel cup and the internal magnet, separation sleeve also is the interior empty circumferential of bottom opening, and its circumference external diameter is slightly less than magnet steel cup circumference internal diameter, and separation sleeve is fixedlyed connected with motor housing by link press span.Be internal magnet in the separation sleeve, internal magnet is the circumferential entity, and its circumference external diameter is slightly less than the separation sleeve internal diameter.One end of internal magnet is equipped with a bit of titanium axle, and the other end of titanium axle places in the interior aperture of separation sleeve; The other end edge of internal magnet directly is connected with pressurizing propeller in the two-stage pumping device, middle during by drawing liquid and work in main shaft and the two-stage pumping device, motor shaft drives the magnet steel cup and rotates, under the magnetic principles effect that south poles is attracted each other, internal magnet rotates with identical speed simultaneously with the magnet steel cup, rotates together thereby drive pressurizing propeller and draw the liquid impeller.Under the effect of drawing the liquid impeller, by liquid entering hole, go up the liquid pipe, arrived liquid outlet by the drawing liquid body, reach the drawing liquid purpose by the pressurizing propeller back of pressurizeing once more.
The beneficial effects of the utility model are: because separation sleeve will by the drawing liquid body and motor shaft is kept apart fully and separation sleeve, internal magnet, impeller, last liquid pipe and main shaft are all made with resistant material, so avoided corrosion and electric leakage problem fully, prolonged the life-span of Under Water Pumps effectively and reduced leak current fault because of the motor that causes from the motor shaft leakage; Simultaneously, the two-stage pumping device has utilized the energy of motor better, has increased useful horsepower.
Description of drawings
Accompanying drawing is a cross-sectional schematic of the present utility model.
Among the figure, 1 motor, 2 link press spans, 3 separation sleeves, 4 pressurizing propellers, 5 liquid outlets, 6 pump covers, liquid pipe on 7,8 tetrafluoro bearings, 9 draw the liquid impeller, and 10 draw the liquid mouth, 11 motor shafts, 12 magnet steel cups, 13 internal magnets, 14 tetrafluoro bearings, 15 main shafts.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Among the figure, the motor shaft 11 of motor 1 is fixedlyed connected with magnet steel cup 12, and magnet steel cup 12 is made by the magnetic steel material, interior empty circumferential, bottom opening.Be separation sleeve 3 between magnet steel cup 12 and the internal magnet 13, separation sleeve 3 also is the interior empty circumferential of bottom opening, and its circumference external diameter is slightly less than the circumference internal diameter of magnet steel cup 12, and separation sleeve 3 is fixedlyed connected with the shell of motor 1 by link press span 2.Be internal magnet 13 in the separation sleeve 3, internal magnet 13 is the circumferential entity, and its circumference external diameter is slightly less than the internal diameter of separation sleeve 3.One end of internal magnet 3 is equipped with a bit of titanium axle, and the other end of titanium axle places the internal diameter of separation sleeve 33.One end of internal magnet 3 is equipped with a bit of titanium axle, and the other end of titanium axle places in the aperture in the separation sleeve 3; The other end edge of internal magnet 13 directly is connected with pressurizing propeller 4 in the two-stage pumping device, middlely is connected by a mouth with the upper end of main shaft 15.The upper end of main shaft 15 is connected with internal magnet with the silk mouth, and the middle-end of main shaft 15 and lower end are fixing by tetrafluoro bearing 14 and tetrafluoro bearing 8 respectively, the lower end of main shaft 15 with draw liquid impeller 9 and fixedly connected.Last liquid pipe 7 in the two-stage pumping device is fixed with the shell of motor 1 by pump cover 6 and link press span 2.During work, motor shaft 11 drives magnet steel cups 12 and rotates, and under the magnetic principles effect that south poles is attracted each other, internal magnet 13 rotates with identical speed simultaneously with magnet steel cup 12, thereby drives pressurizing propeller 4 and draw liquid impeller 9 and rotate together.Under the effect of drawing liquid impeller 9, by liquid entering hole 10, go up liquid pipe 7,, reached the drawing liquid purpose by the drawing liquid body by the pressurizing propeller 4 back arrival liquid outlet 5 that pressurize once more.
Because separation sleeve 3 will be by the drawing liquid body with motor shaft 11 be kept apart fully and separation sleeve 3, internal magnet 13, pressurizing propeller 4, draw liquid impeller 9, last liquid pipe 7 and main shaft 15 and all use resistant material (industrially pure titanium or engineering plastics) to make, so avoided corrosion and electric leakage problem fully, prolonged the life-span of Under Water Pumps effectively and reduced leak current fault because of the motor 1 that causes from motor shaft 11 leakages; Simultaneously, the two-stage pumping device has utilized the energy of motor 1 better, has increased useful horsepower.
Emphasis of the present utility model is the manufacturing that magnetic transmission device and two-stage pressurization device is applied to Under Water Pumps, if only change the Placement of magnet steel cup and motor shaft or impeller and internal magnet, then all should be considered as invading right of the present utility model.
