Description
Technical field
The utility model relates to chamber correlative technology field, specially a kind of low-atmospheric pressure test by strong Magnetic drive
Case.
Background technique
Currently, the fan drive of low pressure test chamber in the market, is all made of motor and directly drives fan rotation with axis.
This kind of drive requires to open a circular hole more slightly bigger than motor shaft diameter on cabinet, after motor shaft circular hole is passed through,
It is loaded on fan.Since the cabinet inside and outside differential pressure of low pressure test chamber is larger, and motor shaft will rotate, so motor shaft and circle
Gap between hole is difficult to be fully sealed, to cause the air-tightness of chamber bad, and can generate biggish noise.
Utility model content
The purpose of this utility model is to provide a kind of low pressure test chambers by strong Magnetic drive, existing low to solve
The fan drive of pressure box is all made of motor and directly drives fan rotation with axis, be easy to cause the airtight of chamber
Property is bad, and can lead to the problem of biggish noise.
To achieve the above object, the utility model provides the following technical solutions a kind of low-atmospheric pressure test by strong Magnetic drive
Case, including fan, cabinet, sealing plate, motor, internal rotor, sealing ring, outer rotor and strong magnets, the box outer surface are opened
It is mounted with sealing ring at hole, and is pressed with sealing plate on the outside of sealing ring, is mounted with motor on the outside of the cabinet, and install on motor shaft
There is outer rotor, the box inside is mounted with fan, and internal rotor is equipped on fan shaft, on the internal rotor and outer rotor
Strong magnets are installed, and together with internal rotor attracts each other with outer rotor.
Preferably, the axis of the axis of the fan and motor is arranged in same level height.
Preferably, the sealing ring is set as O-ring seal.
Preferably, the strong magnets are provided with two groups, and the strong magnets installation site in internal rotor and outer rotor and
It is highly all the same.
Compared with prior art, the utility model has the beneficial effects that should be adopted by the low pressure test chamber of strong Magnetic drive
With strong Magnetic drive, structure is simple, easy for installation, simplifies production technology, facilitates maintenance, without opening on cabinet to transmission shaft
Hole, ensure that the sealing performance of cabinet, and eliminate the noise generated at transmission by gas leakage, cabinet and sealing plate it
Between O-ring seal sealing is added, while using the pressure difference inside and outside cabinet, air-tightness of the cabinet at transmission has been effectively ensured.
Detailed description of the invention
