Abstract
The utility model discloses a one-shaft motor pump set. The one-shaft motor pump set comprises a motor integrated shaft, a motor main body and a pump main body, wherein the motor main body is connected with the pump main body through the motor integrated shaft. The front end of the motor integrated shaft is provided with a key groove, the one-shaft motor pump set further comprises a cylindrical key, the pump main body comprises a pump stator-rotor unit, the cylindrical key is installed between the key groove and the pump stator-rotor unit in a clamped mode, the motor integrated shaft is connected with the pump main body through the cylindrical key, and when the motor integrated shaft rotates, the cylindrical key drives a rotor in the pump stator-rotor unit to rotate. A motor front cover of the motor main body is connected with a pump front cover of the pump main body to form an integrated structure. The one-shaft motor pump set guarantees concentricity of products, the front cover of a motor is connected with the front cover of a pump, and noise of the products is controlled; and the one-shaft motor pump set is light in weight, small in size, compact in structure, long in service life and capable of greatly reducing noise, and as the motor and the pump are uniaxial, and the motor drives the pump synchronously, efficiency is improved, consumed energy is saved, and the purposes of national energy conservation and emission reduction are advocated.
Description
Technical field
The utility model relates to dynamo-electric field, and particularly an a kind of shaft motor pump group is applied on the conveyance systems such as lathe, lubrication system, wind-powered electricity generation, boats and ships, refrigeration equipment, hydraulic system.
Background technique
At present, in Hydraulic Industry, some high-precision requirement of meeting demand, the product in the squelch.Now on the market, the electric-motor pump set type mainly is that motor adds central cover to add coupling, motor-hollow axle and pump direct insertion.
Motor adds the combination that central cover adds coupling, can cause noise large, and concentricity is poor, takes up room large Heavy Weight.The combination that motor-hollow axle and pump are direct insertion also can cause noise large, and concentricity is poor, takes up room little, and the keyway of pump is easily bad, is easily battered down, and working life is short, and efficient is low.
The installation of domestic present existing electric-motor pump group combination generally is complex structure, carries and inconvenience is installed, and therefore designs a kind of lightweightly, and volume is little, and noise is low, and the product that is fit to environmental protection is particularly important.
Summary of the invention
The first purpose of the present utility model provides an a kind of shaft motor pump group, has guaranteed the concentricity of electric-motor pump group, raises the efficiency, and energy efficient is advocated the target that national energy-saving reduces discharging.
The second purpose of the present utility model provides an a kind of shaft motor pump group, thereby because the electric-motor pump group is lightweight, volume is little, compact structure has prolonged the life-span and greatly reduce noise.
For achieving the above object, the utility model provides an a kind of shaft motor pump group, comprises motor integral axle, motor main body and pump body, it is characterized in that, described motor main body be connected pump body and connect by described motor integral axle.
Further, establish keyway on the front end of described motor integral axle, a described shaft motor pump group also comprises round key, described pump body comprises the pumping rotor, described pumping rotor comprises stator and rotor, and described round key is fastened between described keyway and the described pumping rotor, and described motor integral axle connects described pump body by described round key, when described motor integral axle rotated, described round key drove described rotor and rotates.
Further, the front motor cover of described motor main body and the integral structure of the pump front cover of described pump body for linking to each other, described motor integral axle passes described front motor cover and described pump front cover.
In sum, the used axle of motor and pumping is that same single mandrel (being the motor integral axle) forms, and drives the rotor of pumping the inside by the motor integral axle, and the motor driving pump is synchronously, raise the efficiency, and energy efficient.Described front motor cover and pump front cover are integrally connected, and have made the smaller volume of pumping.
Compared with prior art, the utlity model has following advantage:
1, because front motor cover and pump front cover are the structure that is integrally connected, so electric-motor pump group noise is low, easy to use;
2, because motor and the used axle of pumping are same single mandrel, so that the electric-motor pump group has guaranteed the concentricity of product, performance accuracy is high;
3, because motor and the used axle of pumping are same single mandrel, and front motor cover and pump front cover be integrally connected, so the electric-motor pump group is lightweight, volume is little, compact structure.
Description of drawings
Fig. 1 is overall structure sectional view of the present utility model;
Among the figure: 10 shafts, 11 keyways, 20 motor main bodys, 21 front motor covers, 30 pump bodies, 31 pump front covers, 32 pumping rotors, 40 round keys.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made detailed explanation, but following implementation column is not for limiting the utility model.
Fig. 1 is overall structure sectional view of the present utility model.
Referring to Fig. 1, an a kind of shaft motor pump group comprises motor integral axle 10, motor main body 20 and pump body 30, it is characterized in that, motor main body 20 is connected with pump body by 10 connections of motor integral axle.
Establish keyway 11 on the front end of motor integral axle 10, one shaft motor pump group also comprises round key 40, pump body 30 comprises pumping rotor 32, pumping rotor 32 comprises stator and rotor, round key 40 is fastened between keyway 11 and the pumping rotor 32, motor integral axle 10 connects pump body 30 by round key 40, and when motor integral axle 10 rotated, round key 40 drove this rotor and rotates.
The front motor cover 21 of motor main body 20 and the integral structure of the pump front cover of pump body 30 31 for linking to each other, motor integral axle 10 passes front motor cover 21 and pump front cover 31.
In sum, the utility model has guaranteed the concentricity of product, and the protecgulum of motor and pumping is connected, and has controlled the noise of product; Also have lightweight, volume is little, compact structure, Durability long, greatly reduce noise, because electric-motor pump is an axle, the motor driving pump be synchronously, raises the efficiency, energy efficient is advocated the target of national energy-saving reduction of discharging.The utility model mainly is to be fit to wind power generation lubrication system, lubrication system, industrial refrigeration equipment, hydraulic system, the Machinery Tool Automation production line, require quiet occasion automatic production line, screw machine, the hydraulic pressure automatic fields such as auto production line, the utility model is realized the noise environmental protection index that country advocates all the time.
Described several embodiment gives an example for convenience of description, and the interest field that the utility model is advocated should be as the criterion so that claim is described, but not only limits to described embodiment.All equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
