Abstract
The invention relates to a separating-type fan in a standard container of a flow test device. A permeable silicon steel plate is installed on a flange connector of the standard container in a sealed mode, a stator component and a rotor component are installed on two sides of the permeable silicon steel plate respectively, the stator component is located on the external of the standard container, and the rotor component is located in the standard container. A separating-type brushless electric machine structure is adopted in the fan, due to the fact that a stator is located on the external of the standard container, heat generated by operating currents of a winding of the stator cannot influence the temperature in the standard container, although rotor of the fan is located in the standard container, a permanent magnet is adopted in the rotor and generates a magnetic field, no currents exist in the rotor, and heat cannot be generated.
Description
Technical field
The present invention relates to a kind of flow calibrating device, particularly relate to a kind of stable interior separate type fan in internal temperature field that is beneficial to flow test volumetric standard.
Background technology
The stability of control of internal temperature field that improves the volumetric standard of flow standard device is that experimental rig promotes one of the most effectively assurance means of uncertainty.The fan using of current volumetric standard inside all has mechanical connection with external container, causes the heat transmission of internal tank existence and external container, has directly affected the stability in the temperature field of internal tank.The present invention is intended to by the characteristic of silicon steel magnetic conduction, makes the rotor portion of fan be isolated in internal tank, there is no direct heat exchange with outside, also can not bring blower fan additional heat into, can guarantee fully the stable of internal tank temperature field.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides separate type fan in a kind of device for testing flow volumetric standard, this blower fan has adopted the structure of the brushless electric machine of separated examination. because laundry is outside at volumetric standard, although the heating that the operating current on its winding produces can not have influence on the temperature of volumetric standard inside. and its rotor is in the inside of volumetric standard, but it adopts permanent magnet to produce magnetic field, its internal rotor does not have electric current, therefore can not produce heating yet.
For achieving the above object, the technical solution adopted in the present invention is: separate type fan in a kind of device for testing flow volumetric standard, comprise stator component, rotor part, magnetic conduction silicon steel sheet, be characterized in: the sealing of magnetic conduction silicon steel sheet is arranged on the flange connector of volumetric standard, stator component and rotor part are arranged on respectively the both sides of magnetic conduction silicon steel sheet, wherein, stator component is in the outside of volumetric standard, and rotor part is in the inside of volumetric standard.
Stator component contains two cavitys, places the control board of motor in the cavity of top, fixedly mounts the stator winding of motor in the cavity of lower end, and the lead-out wire of stator winding is guided on control circuit board through the housing of lower end cavity.
Rotor part comprises permanent magnet rotor dish, rotating shaft, the rotor case that is used to form rotor field and produces without rotor current, and in rotor case, by rotor bearing connection rotating shaft, rotating shaft upper end is fixedly connected with permanent magnet rotor dish, and lower end is fixedly connected with fan blade.
Between magnetic conduction silicon steel sheet and flange connector, by sealing ring, be tightly connected.
Compared with prior art, the invention has the beneficial effects as follows: this blower fan has adopted the structure of the brushless electric machine of separated examination. because laundry is outside at volumetric standard, although the heating that the operating current on its winding produces can not have influence on the temperature of volumetric standard inside. and its rotor is in the inside of volumetric standard, but it adopts permanent magnet to produce magnetic field, its internal rotor does not have electric current, therefore can not produce heating yet.
Accompanying drawing explanation
Fig. 1 is that the present invention is arranged on the schematic diagram on volumetric standard;
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, separate type fan in device for testing flow volumetric standard of the present invention, comprises stator component 1, rotor part 2, sealing ring 4, magnetic conduction silicon steel sheet 5 etc.
Stator component 1 and rotor part 2 are arranged on respectively the both sides of magnetic conduction silicon steel sheet 5.On the flange connector 8 that is arranged on volumetric standard 3 that magnetic conduction silicon steel sheet 5 is sealed.Be the stator component 1 of blower fan in the outside of volumetric standard 3, the rotor part 2 of blower fan is in the inside of volumetric standard 3.Between magnetic conduction silicon steel sheet 5 and flange connector 8, by sealing ring 4, be tightly connected.Rotating magnetic field stator being produced by a kind of magnetic conduction silicon steel sheet 5 is delivered on permanent magnet rotor dish, thereby promotes blower fan rotation.Owing to only having stator component 1 to produce heating, and laundry is in the outside of volumetric standard 3, and the rotor part 2 of volumetric standard 3 inside does not have electric current, can not produce heat, so can not interfere with the temperature of volumetric standard 3 inside.
As shown in Figure 2, stator component contains 2 cavitys, places the control board 7 of motor in the cavity of top, fixedly mounts the stator winding 6 of motor in the cavity of lower end, and the lead-out wire 9 of stator winding 6 is guided on control circuit board 7 through the housing of lower end cavity.
When control circuit board 7 is started working, to drive stator winding 6 to produce axial rotating magnetic field. this rotating magnetic field is through magnetic conduction silicon steel sheet 5, thereby promoting 10 rotations of permanent magnet rotor dish. this permanent magnet rotor dish 10 is connected with rotating shaft 12. when permanent magnet rotor dish 10 starts to rotate, driving rotating shaft 12 to rotate together, thereby drive fan blade 11 rotations that are arranged in rotating shaft 12. rotating shaft 12 is fixed on rotor case 13 by two rotor bearings 14.
