The support body is fixedly mounted on a shell, and a motor front end cover is fixedly mounted on the support body; one end of a motor shaft is mounted on the support body by virtue of a bearing, the other end of the motor shaft is mounted on the motor front end cover by virtue of a bearing, a rotor is fixedly mounted on the motor shaft, a stator coil is fixedly mounted in the support body, an impeller is fixedly mounted on the motor shaft arranged on the outer side of the motor front end cover, a junction box cover is covered in the wiring position of the protective cover, a wiring block is arranged in the junction box cover, the wiring block is fixedly mounted at a wire outlet hole of the support body, one end of an outlet wire is connected to the stator coil, and the other end of the outlet wire penetrates through the support body and is connected to the wiring block. The three parts, namely the protective cover, the motor body and the junction box seat are made into a whole, thereby reducing the connection links to the least extent, improving the sealing property and improving the protection level of the whole fan. The axial flow fan is simple, reliable and convenient to assemble and maintain.
Description
Technical field
The utility model relates to a kind of blower fan, especially a kind of axial-flow blower that protective housing, motor body and three parts of junction box seat is integrated into a support.
Background technique
Along with country constantly improves the requirement of energy consumption, important means that subtract consumption reduction have been become as the motor frequency conversionization of power source.The continuous expansion of the scope that variable-frequency motor uses, it is increasingly high to require motor to adapt to the bad working environment ability.So just heat transmission blower fan on the supporting variable-frequency motor is proposed higher requirement of shelter, to adapt to rugged environment.
What the matched blower fan of current variable-frequency motor was commonly used is impeller of driven by motor of three-support, and the motor outlet method directly is that the RVV that adopts is directly connected in the terminal box, and security level can only reach IP54.Can not satisfy main machine operation environment requirement.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology; A kind of security level that can improve blower fan is provided, adapts to outside rugged environment, makes the security level of whole blower fan bring up to IP66, protective housing, motor body and junction box seat three are integrated into the axial-flow blower of a support.
The technological scheme that provides according to the utility model; The said axial-flow blower that protective housing, motor body and junction box seat is integrated into a support; Comprise casing, impeller, motor front cover, stator coil, rotor, support, outlet, tagblock and connector cover and mechanical seal; Hard-wired support on casing is installed with the motor front cover on support, described motor component is positioned at support and front cover; On support, the other end of motor shaft on the motor front cover, and stretches out front cover through rotating shaft after the mechanical seal with Bearing Installation to one end of said motor shaft with Bearing Installation; On motor shaft, be installed with rotor; At the support internal fixation stator and coil are installed, on the motor shaft in the motor front cover outside, are installed with impeller, on the wiring position of support, be stamped connector cover; In connector cover, be provided with tagblock; Described tagblock is fixedly mounted on support wire outlet place, and an end of outlet is connected on the stator coil, and the other end of outlet passes support and is connected on the tagblock.
Between described support and connector cover, be provided with the rubber pad envelope.Between protective housing and the front cover seal ring is arranged.Between front cover hole and motor bearings, there is mechanical seal to seal.
The mode that the utility model is made an integral body (being support) with protective housing, motor body and three parts of junction box seat makes connecting link reduce to minimum, improves sealing, improves the security level of whole blower fan, can reach IP66.
The utility model is simple and reliable, assembles easy to maintenance.

Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: this is combined into protective housing, motor body and junction box seat three the axial-flow blower of a support; Comprise casing 1, impeller 2, motor front cover 3, stator coil 4, rotor coil 5, support 6, outlet 7, tagblock 9 and connector cover 10; Hard-wired support 6 on casing 1; On support 6, be installed with motor front cover 3, described motor front cover 3 is positioned at casing 1; On support 6, the other end of motor shaft 11 on motor front cover 3, is installed with rotor 5 with Bearing Installation to one end of said motor shaft 11 on motor shaft 11 with Bearing Installation; At support 6 internal fixation stator coil 4 is installed; Described stator coil 4 and rotor 5 are installed with impeller 2 being to produce magnetic action under to rotate on the motor shaft 11 in motor front cover 3 outsides, be stamped connector cover 10 at the wiring position of support 6; In connector cover 10, be provided with tagblock 9; Described tagblock 9 is fixedly mounted on support 6 outlet positions, and an end of outlet 7 is connected on the stator coil 4, and the other end of outlet 7 passes support and is connected on the tagblock 9.
Between described support 6 and connector cover 10, be provided with rubber pad envelope 8, the rubber pad envelope is arranged between support and the front cover.Between front cover hole and motor bearings, there is mechanical seal 12 to seal.
The utility model is formed motor component by stator 4, rotor coil 5, motor shaft 11 with motor front cover 3 in order to improve the security level of blower fan; Form connecting part by tagblock 9 and connector cover 10;
The utility model adopts wind scooper, motor body and junction box seat is integrated into an integral body, reduces that the three connects and blow-by hidden danger that produce, raising sealing grade.Having integrated three functions like 6, one parts of the support in the schematic representation is cassette holder at the bottom of motor body, air intake protective housing, the wiring.The outlet 7 of motor is after from stator coil 4, drawing, and directly passes in the aperture in the middle of the supporting rib from support 6, is connected on the fixing tagblock 9 in the wiring position on top.As long as whole wiring position covers connector cover 10, take rubber pad envelope 8 to seal between connector cover 10 and the support 6.This device just can make the electrical equipment and electrical position and the external world play tight protection state.
The structure of employing the utility model can reach the security level of blower fan the standard of security level IP66 from IP54.
