Abstract
The invention relates to an amphibious magnetic force driving pump. An outer magnetic rotor of the pump is directly connected with a motor shaft through a key, and is axially fixed by a thrust washer and a bolt; and a connector is directly connected with a motor shell by adopting a static seal. An internal enclosure of a water-cooled motor is fully closed, and the outside of the enclosure is provided with a cooling water jacket. A cooling water inlet pipe is led out from a pump outlet and is connected with the bottom of the cooling water jacket; a cooling water outlet pipe is led out from the top of the cooling water jacket and is connected with a pump inlet; and both the cooling water inlet pipe and the cooling water outlet pipe are provided with valves. During working, the water-cooled motor directly drives the outer magnetic rotor, and the magnetic force passes through an isolation sleeve and is acted on an inner magnetic rotor so as to drive an impeller to realize liquid delivery. No matter on the land or under the liquid, the amphibious magnetic force driving pump is not affected by the change of the external working environment, and can be applied to the operation under the complex environment.
Description
Technical field
The present invention relates to fluid machinery, refer in particular to amphibious formula magnetic force driving pump, be mainly used in and carry poisonously, inflammable, explosive, corrosion and various valuable medium can be easily worked in the environment on land with under the liquid.
Background technique
When common magnetic force driving pump is carried liquid medium, the operation of can only working on land.Under particular surroundingss such as cabin, need and can in terrestrial environment, work, can in environment under the liquid, move again.The motor of common magnetic force driving pump, carriage member have determined it to work in environment under the liquid, can not accomplish amphibious.Disclose a kind of magneto drive pump structure as Chinese patent CN200410091992.X, have the characteristics of anti-exhausting and anti-dry grinding, but internal structure has been provided with sliding bearing and carriage member, can't work in environment under the liquid.Chinese patent CN200830215786.4 discloses a kind of amphibious pump structure, be characterized in easily working in the environment under the land and liquid, but this pump can't accomplish not have leakage fully, be not suitable under liquid poisonous in conveying, inflammable, explosive, corrosion and various valuable medium.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing magnetic force driving pump because the structure of axle envelope, carriage member and common electric machine, the sealing deficiency, the shortcoming that can't move under liquid provides a kind of magnetic force driving pump of being furnished with water-cooled full closed motor, having special shaft extension structure.The motor cooling medium is the conveying liquid of pump, the influence that machine operation is not changed by external environment condition, thus accomplished amphibious.
For achieving the above object, the technological scheme that the present invention takes is: adopt Drive Technology to realize not having and leak, pump directly is connected by special shaft extension structure and static seal with motor; Motor housing design cooling jacket in complete closed utilizes and carries liquid as the motor cooling medium.
A kind of magnetic force driving pump, by the pump housing, impeller, interior magnet rotor, outer magnet rotor, separation sleeve, water-cooled machine is formed, and its China and foreign countries' magnet rotor directly is connected with the motor shaft extension by key, utilizes thrust washer and bolt axial restraint; Connecting body adopts static seal directly to be connected with motor casing.Its working principle is: water-cooled machine directly drives outer magnet rotor, and magnetic force passes through separation sleeve, acts on interior magnet rotor, and then drives impeller realizes the liquid conveying.
The water-cooled full closed motor that the present invention is equipped with, the inside casing of its motor is airtight fully, and the casing outside is furnished with cooling jacket, and the cable outlet place of motor all adopts static seal.Pump discharge is drawn the cooling water inlet pipe and is connected with the cooling jacket bottom; The cooling jacket top is drawn the cooling outlet pipe and is connected with pump inlet; Cooling water inlet pipe and cooling outlet pipe all are furnished with valve.Its working principle is: a part carries liquid to can be used as cooling liquid, flows into cooling jacket through the guiding of cooling water inlet pipe, takes away heat after the cooling outlet pipe imports to pump inlet, and can be by valve control cooling flow.
The magnetic drive pump pump housing of the present invention and motor are the full closed structure, adopt static seal to be connected between the pump housing and the motor, thereby complete and external working environment media isolated, and the cooling liquid of water-cooled machine is provided by the conveying liquid of magnetic drive pump, so can in terrestrial environment, work, can in environment under the liquid, move again.
The beneficial effect of type of the present invention is that the present invention compares with common magnetic force driving pump, has omitted carriage member, rolling bearing and oil sealing parts, has guaranteed its sealing, the operation of can working under liquid.Adopt the full closed motor, the present invention no matter be land or liquid under, the influence that not changed by external working environment can be applicable to the work under the complex environment.
