Description
Technical field
The utility model relates to a kind of pump housing technical field, particularly relates to a kind of integral type magnetic drive pump.
Background technique
Magnetic drive pump (magnetic force driving pump) is primarily of pump head, magnetic driver (magnetic cylinder), a few part composition such as motor, connecting bottom board.Magnetic drive pump magnetic driver forms when motor drives outer magnet rotor to rotate by outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve, magnetic field energy penetrates air gap and namagnetic substance, in drive is connected with impeller, magnet rotor makes synchronous rotary, realize the contactless synchronous transmission of power, the movable sealing structure easily revealed is converted into the static seal structure of zero leakage.
The features such as magnetic force driving pump (abbreviation magnetic drive pump) is the new product working principle of permanent magnetism shaft coupling being applied to centrifugal pump, reasonable in design, and technique is advanced, has hermetically sealed, No leakage, corrosion-resistant.Magnetic drive pump is made up of pump, magnetic driver, motor three part.Critical component magnetic driver is made up of outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve.When motor drives the rotation of outer magnet rotor, magnetic field energy penetrates air gap and namagnetic substance, drives magnet rotor in being connected with impeller to make synchronous rotary, realizes the non contact transmission of power, motive sealing is converted into static seal.Because pump shaft, interior magnet rotor are completely closed by the pump housing, separation sleeve, thus thoroughly solve " run, drip, leak " problem, eliminate the potential safety hazard that oil-refining chemical industry is inflammable, explosive, poisonous, hazardous medium is leaked by pump seal.Magnetic drive pump is the branch belonging to water pump field, and magnetic drive pump is the new product that a kind of working principle by permanent magnetism shaft coupling is applied to centrifugal pump.Magnetic drive pump is mainly used in computer constituent, solar fountain, desktop fountain, artwork, coffee machine, drinking machine, soilless culture, water toothpick, water heater pressurizes, hot water circuit, swimming-pool water circulating filtration, foot bath surfing massaging basin, surf bathtub for massage, automobile cooling recirculation system, oil filler, humidifier, air conditioner, medical apparatus, cooling system, sanitaryware etc.Water pump is conveying liquid or the machinery making fluid pressurization.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to conveying liquid and comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.The technical parameter weighing pump performance has flow, inhales journey, lift, air horsepower, water-horse power, efficiency etc.; The types such as volume water pump, vane pump can be divided into according to different working principles.Displacement pump utilizes the change of its swept volume of a single chamber to carry out transferring energy; Vane pump utilizes the interaction of rotary vane and water to carry out transferring energy, has the types such as centrifugal pump, axial-flow pump and mixed flow pump.Centrifugal pump can be divided into interchange water pump according to control principle, have brush DC water pump, brshless DC motor formula water pump, the isolated water pump of brushless direct-current magnetic force.
The magnet of brushless direct-current magnetic force driving pump and impeller are injection molded into the rotor that one forms motor, the axle sleeve of direct molding and forming is had in the middle of rotor, fixing in the housing by high-performance ceramic axle, the stator of motor and circuit board section adopt epoxy resin glue embedding in the pump housing, one deck thin-walled is had to isolate between stator and rotor, without the need to being equipped with traditional mechanical shaft seal, because of but seal completely.The torsion of motor drives permanent magnetic iron (rotor) work running by producing magnetic field after the coil electricity on silicon steel sheet (stator).Carry out n (n is even number) level to magnet to magnetize the magnetic force systems making magnet part mutually form complete coupling.It is relative that the magnetic pole and the magnetic pole of magnet that produce when stator coil are in heteropole, angle of displacement Φ=0 namely between two magnetic poles, and now the magnetic energy of magnetic system is minimum; When magnetic pole turns to homopolarity relatively, the angle of displacement Φ=2 π/n namely between two magnetic poles, now the magnetic energy of magnetic system is maximum.After removing external force, because the magnetic pole of magnetic system repels mutually, magnetic force returns to the minimum state of magnetic energy by making magnet.So magnet produces motion, magnet rotor is driven to rotate.Brushless direct-current water pump passes through electronic commutation, without the need to using carbon brush, magnet rotor and stator silicon steel plate have multi-stage magnetic field, automatically pole orientation can be changed after magnet rotor relative stator rotates an angle, make rotor remain at the same level to repel, thus make brushless direct-current magnetic force separate pump have higher rotating speed and efficiency.
Current existing magnetic drive pump operates in use installs inconvenience, and operation stability is poor, and impeller uses for a long time and easily produces movement.
