The electric pump is in particular suitable for an electric hot oil warming loop system and can make full use of heat generated in the electromagnetic core assembly, which saves energy and prolongs service life.
Description
Technical field
The utility model relates to motor-drive pump.The motor-drive pump used of the electric heating oil heating circulatory system particularly.
Background technique
Existing motor-drive pump is connected to form by motor and pump.Motor is the closed shape structure, and the electromagnetic core parts energising back of motor produces heat and can not discharge rapidly, can not obtain utilizing.The working life of this motor-drive pump is low.
Summary of the invention
Technical problem to be solved in the utility model is to make full use of the heat that the electromagnetic core parts produce, the saving energy, the motor-drive pump of long service life.
The technological scheme that solves its technical problem employing is: a kind of motor-drive pump, it comprises by housing 1, in housing 1, be provided with electronic chamber 10, in electronic chamber 10, be provided with electromagnetic core assembly 13, electromagnetic core assembly 13 places on the inner housing 17, rotating shaft 6 is set in inner housing 17, rotating shaft 6 is loaded in the inner housing 17 built-in bearing 14 and unilateral bearing 11, the motor that housing 1 and end cap 16 connect to form, by the pump housing 2, in the pump housing 2, be provided with internal tooth 4, gear 5 engagements in internal tooth 4 and the rotating shaft 6, be provided with filler opening 7 in the pump housing 2, the pump housing 2 is connected with pump cover 3, is provided with the gear pump that oil outlet 8 is formed on pump cover 3, and the pump housing 2 of gear pump is connected with the housing 1 of motor, its characteristics are: be provided with filler opening 15 on the end cap 16 of motor, the electronic chamber 10 of filler opening 15 and motor, the filler opening 7 of gear pump is communicated with the oily passage of forming of mistake.Filler opening 15 on end cap 16 is connected with filter 9.Or the oil outlet on pump cover 38 is connected with filter 9.
Motor-drive pump of the present utility model, because being communicated with, the filler opening of the interior electronic chamber of the filler opening of end cap and motor, pump formed oily passage, recycle oil is dipped in the electromagnetic core assembly, recycle oil stream can absorb the heat of electromagnetic core assembly during through oily passage, make full use of heat energy, save the energy, simultaneously, improved the working life of motor-drive pump.
Description of drawings
Fig. 1 is a motor-drive pump structure cross-sectional schematic.
Fig. 2 is an A-A generalized section among Fig. 1.
Fig. 3 is a B-B generalized section among Fig. 2.
Embodiment
With reference to Fig. 1-3, motor-drive pump is made up of motor and gear pump.Motor is by housing 1, in housing 1, be provided with electronic chamber 10, in electronic chamber 10, be provided with electromagnetic core assembly 13, electromagnetic core assembly 13 places on the inner housing 17, rotating shaft 6 is set in inner housing 17, rotating shaft 6 is loaded in the inner housing 17 built-in bearing 14 and unilateral bearing 11, and housing 1 and end cap 16 are connected by bolt, be provided with filler opening 15 and form on end cap 16.Electromagnetic core assembly 13 is made up of iron core 13 and coil 12.Gear pump is provided with internal tooth 4 by the pump housing 2 in the pump housing 2, gear 5 engagements in internal tooth 4 and the rotating shaft 6 are provided with filler opening 7 in the pump housing 2, and pump cover 3 is provided with oil outlet 8, and the pump housing 2 and pump cover 3 connect to form by screw.The pump housing 2 of gear pump and the housing of motor 1 are connected by bolt.Crossing oily passage is communicated with by the filler opening 15 of the electronic chamber 10 of the filler opening 15 of end cap 16 and motor, pump cover 16 and forms.Filler opening 15 on end cap 16 is connected with filter 9.Or the oil outlet on pump cover 38 is connected with filter 9.The housing 1 and the inner housing 17 of motor can integral productions.Rotating shaft 6 places a section of iron core 13 to make for permanent-magnet material.
The oil outlet 8 of motor-drive pump can be connected by external pipeline and electric heating oil heating installation, and the oily heating installation of electric heating connects to form the circulatory system with the filler opening 15 of motor-drive pump end cap 16 again.During motor-drive pump work, the electromagnetic core assembly 13 of motor is connected with Ac and produces alternate rotary magnetic field, under the effect of alternate rotary magnetic field power, rotating shaft 6 forward and reverse rotations, but because the effect of unilateral bearing 11, rotating shaft 6 can only unidirectionally be rotated, rotating shaft 6 driven gears 5 rotate, and gear 5 is meshed with the internal tooth 4 of the pump housing 2, make the pump housing 2 form filler opening 7 oil suctions, oil outlet 8 is pressed oil, and fluid absorbs the heat that electromagnetic core assembly 13 is produced in the electronic chamber 10 of flowing through.
