Abstract
The utility model provides a high voltage motor bearing cooling device which cools a bearing chamber in time, and ensures viscosity of lubricating grease and forming of an oil film, and thus enabling a bearing to be in a good lubricating state. The device comprises a mechanical system, a control system and a pipeline connecting the abovementioned two systems, the mechanical system includes a vacuum tank, the outlet of the vacuum tank is connected with a vacuum pump through the pipeline, the vacuum pump is connected a matched motor which controls operation of the vacuum pump, the inlet of the vacuum tank is connected with an oil outlet of the high voltage motor bearing chamber through the pipeline, the control system includes a power switch which controls start and stop of the vacuum pump, and a vacuum meter and a pressure controller which are arranged at the inlet of the vacuum tank, the pressure controller is electrically connected with a solenoid valve mounted on the pipeline between the vacuum tank and the bearing chamber.
Description
Technical field
The utility model relates to a kind of motor cooling technical field, is specifically related to a kind of high-voltage electric machine bearing heat sink that adopts vacuum action to siphon away unnecessary grease in the bearing chamber.
Background technology
At present, high-tension motor mainly adopts lubricating grease to be lubricated, the bearing chamber ubiquity space of high-voltage three-phase asynchronous motor that rolling bearing is installed is less, oil extraction is not smooth, easily accumulate grease, the defective of radiating effect difference, thereby cause heat accumulation, produce high temperature, for guaranteeing the lubricated of bearing, just need regularly to inject lubricating grease, after lubricating grease is full of bearing chamber, has hindered and produce scattering and disappearing of heat during bearing rotates, cause the bearing of motor temperature to raise, lubricating grease viscosity reduces even the oil film forfeiture, the bearing dry grinding occurs, sintering, damage types such as locking are for guaranteeing the lubricating status of bearing, just need to inject more lubricating grease, it is faster that bearing temperature is raise, and so forms vicious circle, until damage of bearings, the long period that is unfavorable for motor moves continuously, influences the normal operation of continuous type of production enterprise.
Summary of the invention
At above-mentioned technical problem, the utility model provides a kind of timely reduction bearing chamber temperature, guarantee the viscosity of lubricating grease and oil film formation, make bearing be in the high-voltage electric machine bearing heat sink of good lubrication state.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-voltage electric machine bearing heat sink, comprise mechanical system, control system and the pipeline that connects above-mentioned two systems, mechanical system comprises a vacuum tank, the vacuum tank outlet connects a vacuum pump by pipeline, vacuum pump connects the adapted motor of its running of control, the vacuum tank entrance links to each other by the oil drain out of pipeline with the high-tension motor bearing chamber, control system comprises the mains switch of control vacuum pump start and stop and vacuum meter and the pressure controller that is arranged on the vacuum tank porch, and the electromagnetically operated valve electricity that pressure controller and is installed on the pipeline between vacuum tank and the bearing chamber links to each other.
Described vacuum tank bottom is provided with blow-off line, and blow-off line is provided with blowdown valve, and is convenient in time with the systemic unnecessary lubricating grease eliminating of vacuum tank, the normal operation of support equipment.
During this heat sink work, make by the vacuum pump effect and to form vacuum negative pressure condition in the vacuum tank, by being connected in the pipeline effect of bearing of motor chamber, when vacuum degree reaches certain numerical value, electromagnetically operated valve moment that pressure controller control is installed on the pipeline opens, the unnecessary lubricating grease that accumulates in the bearing chamber is sucked out, enlarge the space in the bearing chamber, mediation bearing chamber and the outside passage that is stopped up by lubricating grease make extraneous air enter bearing chamber, and bearing are rotated the heat that produces carry out, thereby reduce the temperature of bearing chamber, guarantee the viscosity of lubricating grease and the formation of oil film, make bearing be in good lubricating status, realize the continuous run in long period of motor.
The beneficial effects of the utility model are according to the narration of such scheme as can be known: this heat sink utilizes vacuum tank and vacuum pump in time the unnecessary lubricating grease that accumulates in the bearing chamber to be sucked out; enlarge the space in the bearing chamber; mediation bearing chamber and the outside passage that is stopped up by lubricating grease; be conducive to shedding of the interior heat of bearing chamber; thereby reduce the temperature of bearing chamber; guarantee the viscosity of lubricating grease and the formation of oil film; make bearing be in good lubricating status; both played the purpose of protection bearing; prolong bearing useful life, can realize that again the long period of motor runs well.
