Abstract
An electromagnetic disc drive pump relates to electric pumps. A liquid inlet and a liquid outlet are arranged on a pump body, a stator is arranged inside the pump body, a fixed shaft is arranged in the center of the stator, a rotor is arranged on the fixed shaft on one side of the stator, an impeller is arranged on the rotor, the rotor is installed on the fixed shaft through a self-lubricating bearing, and a retaining screw is arranged at a fixed end and on one side of the rotor impeller, and a backpressure chamber is arranged between the rotor and the stator and communicated with a high pressure chamber. The bearing needs no additionally provided with lubricating oil since the rotor is installed on the fixed shaft through the self-lubricating bearing, and thereby the pump is simple in manufacturing and installation, and low in manufacturing cost. The backpressure chamber arranged between the rotor and the stator is communicated with the high pressure chamber, pressures on two sides of the rotor are balanced, axial moving force of the rotor can be automatically eliminated, no friction force exits between the rotor and the stator, and the rotor is low in rotation resistance, low in energy consumption and low in manufacturing cost and use cost and accordingly is applicable to various electromagnetic pumps.
Description
Technical field
The utility model relates to motor-drive pump, says it is the moving pump of a kind of electromagnetism disk in detail.
Background technique
We know existing electromagnetic pump, be on the pump housing, to be provided with liquid entering hole and liquid outlet, be provided with stator in the pump housing, stator center is provided with stationary axle, the stationary axle of stator one side is provided with rotor, rotor is provided with impeller, disclosed on February calendar year 2001 21 as State Intellectual Property Office, application number is 00123009.3, and name is called the application for a patent for invention of electromagnetic heat pump, be on rotor, to be provided with stuffing box gland, be provided with bearing in the stuffing box gland, be installed on the stationary axle, it is that bearing is carried arch lubricant oil that the stationary axle center is provided with center hole, be provided with shielding can between stator cavity and the pump chamber, be provided with damping ring between rotor and the shielding can.This electromagnetic pump is installed on the stationary axle through stuffing box gland because the bearing of rotor is installed, and it is that bearing is carried arch lubricant oil that the stationary axle center is provided with center hole, and the manufacturing process complexity is installed trouble, the manufacture cost height; Owing to be provided with shielding can between stator cavity and the pump chamber, be provided with damping ring between rotor and the shielding can, frictional force is big between rotor and the stator, and the rotor rotation resistance is big, and power consumption is high, the manufacturing cost and use cost height, and be difficult to eliminate the axial float power of rotor.
Summary of the invention
The technical problem that the utility model solves is, solves the bearing that rotor is installed and is installed on the stationary axle through stuffing box gland, and it is that bearing is carried arch lubricant oil that the stationary axle center is provided with center hole, and the manufacturing process complexity is installed trouble, the manufacture cost height; Be provided with shielding can between stator cavity and the pump chamber, be provided with damping ring between rotor and the shielding can, frictional force is big between rotor and the stator, the rotor rotation resistance is big, power consumption is high, the manufacturing cost and use cost height, and be difficult to eliminate the problem of the axial float power of rotor, provide a kind of easy to manufacture and install, zerofriction force between rotor and the stator, the rotor rotation resistance is little, and it is low to consume energy, manufacturing cost and use cost is cheap, and can eliminate the moving pump of electromagnetism disk of the axial float power of rotor automatically.
The technical solution of the utility model is, the pump housing is provided with liquid entering hole and liquid outlet, be provided with stator in the pump housing, stator center is provided with stationary axle, and the stationary axle of stator one side is provided with rotor, rotor is provided with impeller, the main structure characteristics are, rotor is installed on the stationary axle through self oiling bearing, and impeller of rotor one side, fixedly the termination is provided with stopping screw, be provided with back pressure cavity between rotor and the stator, back pressure cavity is connected with hyperbaric chamber.
The beneficial effects of the utility model are that because rotor is installed on the stationary axle through self oiling bearing, bearing does not need to provide in addition lubricant oil again, and is easy to manufacture and install, cheap for manufacturing cost; Because be provided with back pressure cavity between rotor and the stator, back pressure cavity is connected with hyperbaric chamber, the pressure balance of rotor both sides, can eliminate the axial float power of rotor automatically, zerofriction force between rotor and the stator, the rotor rotation resistance is little, it is low to consume energy, and manufacture cost and user cost are cheap.The utility model is applicable to that various electromagnetism disks move pump.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model, also is a kind of embodiment's schematic representation.
Embodiment
Electromagnetism disk as shown in the figure moves pump, and the pump housing 2 is provided with liquid entering hole 3 and liquid outlet 12, is provided with stator 11 in the pump housing 2, and stator 11 centers are provided with stationary axle 5, and the stationary axle 5 of stator 11 1 sides is provided with rotor 10, and rotor 10 is provided with impeller 7.Rotor 10 is installed on the stationary axle 5 through self oiling bearing 6, self oiling bearing 6 is silicated graphite bearings, the silicated graphite bearing does not need to provide in addition lubricant oil again, can realize selflubricating, rotor 10 impellers 7 one sides, stationary axle 5 terminations are provided with stopping screw 4, stopping screw 4 heads can prevent that rotor 10 and self oiling bearing 6 from deviating from, and are easy to manufacture and install, cheap for manufacturing cost.The rotor 10 of self oiling bearing 6 opposite sides and stationary axle 5 are provided with location self oiling bearing 8, and location self oiling bearing 8 can be rotor 10 location.Be provided with back pressure cavity 9 between rotor 10 and the stator 11, back pressure cavity 9 is connected with hyperbaric chamber 1, the pressure balance of rotor 10 both sides, can eliminate the axial float power of rotor 10 automatically, zerofriction force between rotor 10 and the stator 11, rotor 10 rotational resistances are little, and it is low to consume energy, and manufacture cost and user cost are cheap.
