Abstract
The utility model relates to an amphibious magnetic driving pump. An external magnetic rotor is directly connected with a motor shaft by a key and is axially fixed by a thrust washer and a bolt; a connecting body is directly connected with a motor shell by static seal; a casing in a water-cooling motor is completely closed; and the outside of the casing is provided with a cooling water jacket. A pump outlet leads out a cooling water inlet pipe and is connected with the bottom of the cooling water jacket; the top of the cooling water jacket leads out a cooling water outlet pipe and is connected with a pump inlet; and the cooling water inlet pipe and the cooling water outlet pipe are both provided with a valve. When in working, the water-cooling motor directly drives the external magnetic rotor, and the magnetic force passes through an isolating sleeve and is applied on the internal magnetic rotor, thus further driving the impellers to realize liquid conveyance. No matter on land or under water, the amphibious magnetic driving pump is not affected by the external working environment and can be applied to the operation in complex environments.
Description
Technical field
The utility model relates to fluid machinery, refers in particular to amphibious formula magnetic force driving pump, is mainly used in to carry poisonously, inflammable, explosive, and 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 in the utility model 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 utility model is taked 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 utility model 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 utility model 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 effects of the utility model are that the utility model is compared 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 utility model 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.
