Description
Technical field: the utility model belongs to the ex electrical product of using in the explosion hazard area, is a kind of improvement to existing water-cooled flameproof motor.
Background technology: existing water cooling formula flameproof motor generally adopts two kinds of structural designs.First kind is the water leg formula, the shortcoming of this kind structure is, ring-shaped water jacket requires high when welding, processing and assembling are complicated, and the ring-shaped water jacket failure welding in use very easily occurs and cause the recirculated water partial short circuit, and motor radiating is bad, temperature rise, and in case occur leaking, the maintenance of water jacket and change extremely difficultly even causes scrapping of motor, stator and shell.In addition, recirculated water short circuit, water jacket leak and can't monitor, condensed water and the collection of leaking and discharging difficulty, and the scale and sediment deposit thing in the water jacket is difficult to remove.Second kind of structure adopted detachable water cooler, water cooler places the top of enclosure stator, not only solved the dismounting maintenance issues of cooler, and can accomplish the monitoring and the discharging of leaking, but its cooler two ends are in the charge of between plate and shell and have been adopted bolt fastening to cooperate, when the associated components thermal expansion amount not simultaneously, very easily cause the damage of cooler and leak.The drum type brake explosion separation structure of rolling bearing supporting has been adopted in its perforation place in addition, and this kind structure will be joined the bearing distance of car rotating shaft after motor mixes up magnetic center, and difficulty is all compared in the assembling of bearing and maintenance.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming a kind of air water cooling flame-proof type threephase asynchronous is provided, and has solved problems such as I﹠ M inconvenience.The purpose of this utility model be achieved in that it by: rotor, bearing, end cap, pushing cover assembled explosion separation structure, the protective device that leaks hunting, detachable cooler, stator, support are formed.Bearing supporting rotor, end cap link together sliding bearing and support; pushing cover assembled explosion separation structure is connected with end cap, and forms explosion suppresion surface with rotor, and detachable cooler is installed on the support; the protective device that leaks hunting be installed in cooler below, stator is contained in the support.Detachable cooler is made up of: water inlet pipe, outlet pipe, front water chamber, the preceding plate, seam explosion suppresion surface, cooling water pipe, consequence tube sheet, flange, back hydroecium be in the charge of.Water inlet pipe, outlet pipe are connected with front water chamber, and the preceding plate of being in the charge of is connected with the seam explosion suppresion surface, and it is arranged cooling water pipe by many cooling water pipes and constitute, and are installed between front water chamber and the back hydroecium, and are fixed on being in the charge of on the plate of two ends, and the consequence tube sheet is connected with flange.Pushing cover assembled explosion separation structure is made of: key, pushing cover, plate washer, inner end cap.Rotor is contained on the axle sleeve, is connected with pushing cover by key, and plate washer and inner end cap are fixedly clamped pushing cover, and inner end cap is installed on the support.This product is compared with existing flameproof motor, and its parts have all adopted antirust high-abrasive material, is convenient to installation, inspection, maintenance, strong, the good cooling results, stable, safe and reliable of heat-exchange capacity.
