The utility model is characterized in that the existing jacket cooling type motor is improved, a separable type cooler is arranged between a motor stator and a housing, flame-proof structures are arranged on a flame-proof housing and are respectively matched with a front and a back tube supporting plates, a drain hole, a screw plug and an observation window. Compared with the existing flame-proof type motor, the utility model has the advantages of convenient inspection, maintenance and scaling handling, strong heat exchange efficiency and high cooling efficiency; the shape of the housing of the flame-proof motor can be changed from a cylindrical shape to a box shape; the structure of the flame-proof housing is compact, etc.
Description
The utility model belongs to the explosion-proof type electric product technical field of using in the explosion hazard area, is a kind of flameproof motor with detachable water cooler.
Existing water jacket cooled flameproof motor, its type of cooling are in the motor stator-core outside ring-shaped water jacket to be set, and the flame-proof type shell is cylindric.The winding of stator during the motor operation, the heat that iron core and rotor produce is passed to recirculated water in the water jacket by the water jacket inwall, produce distinguished and admirable and circulating water flow takes heat outside the motor casing to and goes by the flabellum of rotor one end, thereby the temperature rise when guaranteeing the motor operation meet the nominal operation requirement.The shortcoming of the prior art water jacket cooling structure is: the water jacket volume of steel plate welding is big, heaviness, and processing and assembling are all complicated, and in a single day occur leaking when using, maintenance or to change water jacket very difficult, even may cause whole motor to scrap.In addition, water jacket leaks and can't monitor, condensed water and the collection of leaking and discharging difficulty.Incrustation scale is difficult to remove in the water jacket.
The purpose of this utility model is for a kind of flameproof motor of making water cooler easy to maintenance that has is provided.
Technical solution adopted in the utility model is improved existing water jacket cooled flameproof motor, be about to be arranged on the ring-shaped water jacket and the corresponding flameproof enclosure structure thereof of stator core outside, change at least one detachable water cooler is set between motor stator and flameproof enclosure, on existing flameproof enclosure, increase corresponding explosion separation structure.And flabellum all is set in two ends of rotor, constitute a kind of novel air water cooled flameproof motor.Its part of implementing heat exchange of this separate type water cooler is to adopt many cooling water pipes to rearrange, the cooling water pipe two ends are fixed on is in the charge of on the plate, and by cover plate with matching the water cooler parts are connected with motor casing, drip tray is set below cooler.The explosion separation structure of motor casing both kept original flame proof measure by prior art at following position: the explosion separation structure that the explosion separation structure that end cap and shell cooperate, rotating shaft and end cap endoporus cooperate, the explosion separation structure of connection box for motor parts.While is the connecting portion between water cooler and shell again, adopts corresponding explosion suppresion surface fit structure.Be in the charge of the position employing cylindrical shape explosion separation structure that plate or front and rear covers are connected with shell promptly; The osculum that on shell wall, is provided with, and the plug screw that cooperates with it is designed to the screw-type explosion separation structure; Be provided with observation window on the motor casing wall, this observation window also is designed to drum type brake or plane formula explosion separation structure.
The utility model can be dismantled taking-up easily owing to the water jacket with secure fit changes detachable water cooler in motor housing, check maintenance and removing incrustation scale or replacing.Because water cooler adopts the multichannel circulation waterway, and matches with the air path system of motor internal, thereby strengthened heat-exchange capacity, improved cooling effectiveness, under equal power condition, the cooler volume obviously dwindles, weight saving.Because water cooler is provided with observation window, is convenient to realize automatic monitoring, has improved running reliability of motor.Since be provided with drip tray and osculum, can be easily with the condensed water of cooler and the discharge shell that leaks.Because water cooler can be arranged on the stator top, the shell of motor can change box-shaped into by cylindrical shape like this, not only can reach the anti-explosion safety requirement, and makes the motor compact overall structure.
Below in conjunction with drawings and Examples structure of the present utility model is further described.
Fig. 1 is the utility model flameproof motor structure partial cutaway view, and Fig. 2 is the structure cutaway view of the detachable water cooler of the utility model flameproof motor.
With reference to Fig. 1, flameproof motor of the present utility model is except stator (3) with existing flameproof motor, rotor (1), support (8), end cap (2), bearing, terminal box etc., also above motor stator, be provided with detachable water cooler, according to heat exchange calculating and wind path design, arrange symmetrical two water coolers (5), horizontal or perpendicular being arranged in parallel adopted in the many cooling water pipes (19) of cooler inside, (20), also can arrange radially.The protecgulum of cooler (14) end face is provided with water-in flange dish (10) and water-output flange dish (9), connects outside inlet tube and outlet tube respectively.The below of water cooler (5) is provided with drip tray (7), is provided with osculum (11) with the corresponding shell wall of drip tray (7) and reaches the plug screw that cooperates with it.Shell wall corresponding to water cooler (5) is provided with observation window (4), and the shell of motor is a box-shaped.Being in the charge of the position that plate or front and rear covers be connected with shell before and after the water cooler (5) is employing cylindrical shape explosion separation structure (6), also the cooperation of one end can be changed into the plane formula explosion separation structure.Connect internal cavities and other outside position on the shell and all adopt the explosion separation structure of existing flameproof motor: the cooperation between End cover for motor (2) and the support (8) is a cylindrical shape seam explosion separation structure (12); End cap (2) endoporus is axle through explosion separation structure (13) with cooperating of rotor (1) axle; The motor connecting cartridge parts that do not show on the figure also are the flame-proof type structure.In motor when operation,, rotor (1) drives inner air by the fan blade on it and flows to stator (3) top by the air channel, divides stator and epitrochanterian heat two the tunnel to take on the cooler (5) and carry out heat exchange.
With reference to Fig. 2, be in the charge of on plate (15) and the consequence tube sheet (18) before being separately fixed at circle at the cooling water pipe (19) that water cooler (5) is arranged in parallel, (20) two ends, protecgulum (14) and before be in the charge of cavity between the plate (15) the middle part be provided with water-stop sheet (16), the water inlet cavity of water-stop sheet (16) bottom internally communicates with water inlet cooling water pipe water (19), and the water outlet cavity on top internally communicates with water outlet cooling water pipe (20).Cavity between the bonnet (17) of water cooler (5) and the consequence tube sheet (18) communicates with the not end of water inlet cooling water pipe (19) and the top of water outlet cooling water pipe (20).In order further to strengthen cooling effect, cooling water pipe should adopt the copper pipe or the aluminum pipe manufacturing of good heat conductivity, and the pipe outer wall is provided with radiating fin.
