Abstract
The utility model relates to the technical field of gear wheel pumps, in particular to a magnetic force driving gear wheel pump, which comprises an outer magnetic cylinder component, a protective covering, a shielding can, an inner magnetic cylinder component, a front shell, a middle shell and a back shell. The magnetic force driving gear wheel pump is characterized in that: the osculum end of the outer magnetic cylinder component 1 is embedded into the cavity body of the protective covering 2 from the left side; a sealed end at the left side of the shielding can 3 is embedded into the cavity body of the protective covering 2 from the right side; the inner magnetic cylinder component 4 is embedded into the cavity body of the shielding can 3 from the left side; the right end of the inner magnetic cylinder component 4 is connected with the front shell 5 through a drive shaft, and the front shaft 5 is fixed at the right side of the protective covering 2 with a bolt. Compared with the prior art, the magnetic force driving gear wheel pump of the utility model is additionally provided with a magnetic force driving component; a transmission shaft does not need to penetrate the pump shell, and utilizes the magnetic field to permeate the air gap and the thin wall of the shielding can to drive the torquemoment and drive an inner magnetic rotor instead, thereby radically eliminating the leakage channel of the shaft gland and realizing complete sealing. Overloading protective function can be brought into play when transferring power, and workload of maintenance, examining and repairing of magnetic force pump is little.
Description
[technical field]
The utility model relates to the gear pump technical field, specifically a kind of gear pump driven by magnetic force.
[background technique]
Gear pump in the market directly connects motor by the outer driving shaft of fore shell mostly and realizes power transmission, unavoidably to produce leakage between the axle envelope thus, add be subjected on gear, axle and the bearing of gear pump pressure imbalance, radial load is big, has limited the raising of its pressure, so general working pressure is lower, flow pulsation is big, cause that pressure pulsation is big, make pipeline, valve etc. produce vibrations, noise is big.
[summary of the invention]
The purpose of this utility model overcomes the deficiencies in the prior art exactly, has set up the magnetic force assembly between axle and motor, and a kind of gear pump driven by magnetic force of design.
For achieving the above object, design a kind of gear pump driven by magnetic force, comprise outer magnetic cylinder component, protective housing, shielding can, interior magnetic cylinder component, fore shell, mesochite, back cover, it is characterized in that: outer magnetic cylinder component accent end embeds in the protective housing cavity from the left side, one of the sealing of shielding can left side in right side embedding protective housing cavity, interior magnetic cylinder component embeds in the shielding can cavity from the left side, and interior magnetic cylinder component right-hand member links to each other with driving shaft with fore shell, fore shell with bolt in the protective housing right side.Described shielding can right-hand member is provided with shade, and shade is positioned at the outer accent end of protective housing cavity, and shielding can shade and fore shell connecting part are provided with shielding can O ring.Sheathed bearing on the driving shaft at described fore shell place, and be fixed in fore shell initiatively in the axis hole with bearing dowel.
The utility model is compared with prior art; set up the magneto drive assembly; because transmission shaft need not penetrate pump case; but utilize magnetic field to see through air gap and separation sleeve thin-walled driving torque; therefore magnet rotor in driving has fundamentally eliminated the leakage way that axle seals, and has realized sealing fully; overload protective function is arranged during transferring power, and the maintenance and the maintenance workload of magnetic drive pump are little.
[description of drawings]
Fig. 1 is a STRUCTURE DECOMPOSITION schematic representation of the present utility model.
Appointment Fig. 1 is a Figure of abstract.
Referring to accompanying drawing 1,1 is outer magnetic cylinder component; 2 is protective housing; 3 is shielding can; 4 is interior magnetic cylinder component; 5 is fore shell; 6 are shielding can O ring; 7 bearings; 8 bearing dowels.
[embodiment]
Be described further below in conjunction with accompanying drawing.
Between the fore shell of original gear pump and motor, set up the magneto drive parts, be specially the interior two ends of protective housing 2 cavitys outer magnetic cylinder component 1 and shielding can 3 are installed respectively, magnetic cylinder component 4 in installing in shielding can 3 cavitys, shielding can O ring 6 is installed between shielding can 3 right-hand member shades and the fore shell 5 is played sealing and antifrictional effect, interior magnetic cylinder component 4 right-hand members and fore shell 5 link to each other with driving shaft, establish bearing 7 on the driving shaft in the active axis hole of fore shell 5, and fixing with bearing dowel 8, reduce the wearing and tearing between fore shell 5 and the driving shaft.
Magnetic drive pump utilizes the working principle of magnetic shaft coupling, promptly utilize the magnetic drives of permanent magnet to realize moment of torsion, and fully finish non contact transmission, the outer magnet rotor of driven by motor, when promptly outer magnetic cylinder component 1 forms rotation, the effect magnetic line of force by magnetic field passes magnet rotor in shielding can 3 drives, 4 formation of magnetic cylinder component and impeller rotate synchronously promptly, because the shade that shielding can 3 right-hand members are established is enclosed in the static shielding can 3 medium in the pump, leak the purpose of pumping medium thereby reach not have, thoroughly solved the shaft sealing leakage of mechanical pump.
The density of this magnetic drive pump fed sheet of a media is not more than 1300kg/m3, viscosity is not more than the liquid that does not contain ferromagnetism and fiber of 30 * 10-6m3/S, the rated temperature of conventional magnetic drive pump is metal material or F46 lining for the pump housing, and Maximum operating temperature is 80 ℃, and rated pressure is 1.6MPa; The serviceability temperature of High-temperature Magnetic Pump=350 ℃; For the pump housing is non-metallic material, and maximum temperature is no more than 60 ℃, and rated pressure is 0.6MPa.
Magnetic drive pump is hermetically sealed with it, do not have leak, corrosion-resistant characteristics, be widely used in oil, chemical industry, The departments such as pharmacy, plating, environmental protection, water treatment, video display developing and printing, national defence are used for pumping inflammable, easy Quick-fried, poisonous and precious liquid.
