Abstract
The utility model discloses an internal cooling type vortex pump. An improved design is made to an impeller and the pump body of the pump. Double-face vane type is adopted in the impeller. A slope angle is arranged between the vane and a wheel drum plane. An angle is leaned back by the vane along the direction of the radius of the impeller. A helical passageway is arranged in the pump body to cool a motor. The utility model has the advantages of small size, low power consumption, high lifting range, and good cooling effect. The utility model is suitable for shower water carriage, well water fetching, miniature irrigation. The internal cooling type vortex pump is also suitable for pressurizing water carriage when the hydraulic pressure of the city is low.
Description
The utility model relates to a kind of mini electric pump, particularly the inner-cooled peripheral pump.
Present normally used motor-drive pump generally adopts submersible type or additional cooling unit to come the cooling motor temperature inside, but this just requires certain environmental conditions or supplementary equipment to realize.Though having announced a kind of utility application number is 86204715 " inner-cooled motor-drive pump ", its technological scheme is for being provided with axial arranged cooling heat pipe in motor stator core, rotor iron core, by stator and rotor being cooled off to the heat pipe water flowing, but its processed complex, consume material, and because the other end water inlet is depended merely in the sealing of heat pipe one end, cooling effect must be affected.
It is little that the purpose of this utility model provides a kind of volume simple in structure, the lift height, and cost is low, the inner-cooled peripheral pump of good cooling results.
The purpose of this utility model is achieved in that at first, for improving the working efficiency of impeller, designed a kind of two-sided leaf type impeller, the impeller two sides all has blade to distribute, and the position of blade on wheel hub is staggered form at interval, and a tilt angle is arranged between blade and the wheel hub plane, in addition, blade is by the impeller radius direction angle that recedes, and She Ji impeller like this is owing to having adopted two-sided blade to play the effect of two stage pump; Inclination between blade and the wheel hub plane and blade by the impeller radius direction recede an angle strengthened current directivity, reduced the eddy current amount of water, thereby improved the effect of impeller.Secondly, the motor that is positioned at pump housing right-hand member has a peripheral seal wall, the motor seal wall has constituted the peripheral seal of motor with the two end cap of pump, a helical flow channel is set between motor seal wall and pump housing shell, this passage is extended by the side runner that is positioned at pump housing left end comes, be and revolve the spiral shell shape, end at the exhaust port of pump housing right-hand member along motor seal wall circumgyration setting.This helical channel is once molding formed manufacturing.Water boost pressure under the effect of two-sided blade impeller from pump housing left end income mouth is come in by side runner, enters helical channel.Discharge by exhaust port.Water is constantly taken away the heat of motor simultaneously.Because the water of cooling motor is working fluid all the time, so cooling effect is good.In order to reduce power consumption, the utility model inner-cooled peripheral pump adopts the suction port of the pump housing and the structural type that exhaust port is in same horizontal position basically.
The advantage of the utility model inner-cooled peripheral pump is simple in structure, and cost is low, and volume is little, lift height, good cooling results.The power of motor of this water pump adapted is little, and the efficient height is compared with general one-way pump (about 90 degree of feed angle between inlet/outlet), because feed angle is 180 degree between the inlet/outlet of inner-cooled peripheral pump, reaches same effect so can reduce the power consumption of a grade of motor.That the utility model inner-cooled peripheral pump is suitable for is supporting with domestic washing machine, also can be used for shower send water, extracts well water, the supercharging water feeding when small-sized irrigation and municipal water are forced down.
Below, in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the generalized section of inner-cooled peripheral pump.
Fig. 2 is the schematic representation of pump housing suction port one side.
Fig. 3 is the schematic representation of two-sided blade impeller.
(1)-suction port (2) among the figure-impeller (3)-wheel hub (4)-blade (5)-shafting oil envelope (6)-axle (7)-pump housing (8)-helical channel (9)-pump housing shell (10)-motor (11)-motor seal wall (12)-pump end cap (13)-exhaust port (14)-side runner.
The left end of inner-cooled peripheral pump shown in Figure 1 has suction port (1), in impeller (2) is housed, the impeller two sides respectively has 36 winged petiole sheets (4) evenly to distribute, the position of blade (4) on wheel hub (3) is staggered form at interval, each winged petiole sheet is all by the impeller radius direction angle that recedes, in addition, there is a tilt angle (seeing accompanying drawing 3) impeller to be contained on the axle (6) between each winged petiole sheet and the wheel hub plane, drives by axle and rotate.Shafting oil envelope (5) is to be used for stoping water to flow into motor (10) by the between centers crack, the material synthetic rubber of shafting oil envelope.Water enters the pump housing (7) from suction port (1), motion and generation vortex under the effect of impeller (2), water is supercharging at the volley, under the leading role of blade, water-jet is gone into side runner ［ 14 ］ and is pressed into the interior helical channel (8) of the pump housing ［ 7 ］, extrude from exhaust port ［ 13 ］ then, the seal arrangement of motor (16) is made up of motor seal wall (11) and two pump end caps (12), the helical channel (8) that is between motor seal wall (11) and the pump housing shell (9) is to pass through compression molding processing and fabricating, material selection cast aluminium.When water flow through in helical channel, the heat that is produced when constantly motor (10) being worked was taken away, and directly made the motor cooling.
Claims (1)
1, a kind of inner-cooled peripheral pump has impeller, pump cover, the pump housing, motor, and the left end of the pump housing has a suction port, and right-hand member has an exhaust port, and the suction port of the pump housing and exhaust port are in same horizontal plane basically, it is characterized in that:
A, described motor have a peripheral seal wall, and a helical flow channel is arranged between motor seal wall and pump housing shell, and this helical channel extends from the side runner of pump housing left end, is provided with along motor seal wall circumference, and end is positioned at the exhaust port of pump;
B, described impeller are two-sided leaf type impeller, the two sides of impeller all has blade to distribute, and the position of the blade on two sides on wheel hub is staggered form at interval, and a tilt angle is arranged between blade and the wheel hub plane, in addition, blade is by the impeller radius direction angle that recedes.
