Abstract
The utility model relates to an explosion-resistance type self-lubricating three-phase asynchronous motor with high voltage and high speeds. The utility model is composed of a machine seat, a slide bearing, an oil level compensator, fans, a rotor, fan housings and a stator, wherein the slide bearing is arranged on an end cover and is connected with the rotor, and the stator is arranged in the machine seat. The shaft extending end and the non-shaft extending end of the utility model are provided with the fans which are fixed on a shaft. The fan housings covering the fans and the oil level compensator are respectively fixed on the machine seat. The utility model has simple structure, and the assembly of an oil diluting station and an oil passage circulating system is not needed when the utility model is used. The utility model has the characteristics of convenient installation, convenient inspection, convenient maintenance, etc. The utility model is especially suitable for environment of petroleum, chemical industry, pipe laying, ships, etc., which have explosive gas.
Description
Technical field: the utility model relates to a kind of high voltage flameproof high speed self-lubricating threephase asynchronous of electric product.
Background technology: at present, the most sliding bearings that adopt of existing high voltage large-sized flameproof motor are not because the rolling bearing of big model satisfies the high-revolving requirement of 2 utmost point motors.Power is 160
KW～900
KFlameproof motor in the W scope adopts the ring-oil technology, can satisfy the heat radiation requirement of bearing substantially, and power is 900
KThe flameproof motor that W is above then need adopt the enforced lubricating technology, promptly forces lubricating oil along oil circulation by impressed pressure, for sliding bearing provides lubricated, and the heat that bearing produces is in time taken away, and reaches favorable cooling effect.But but there are a lot of shortcomings in this cooling technology: 1, must be equipped with oil supply systems such as Lubricating-oil Station, top petrol tank and oil pipe line.2, oil supply system must with main frame interlock alarm or shutdown.So not only increase cost, when oil supply system breaks down, can bring the trouble of main shut-down system.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of high voltage flameproof high speed self-lubricating threephase asynchronous is provided, and has solved the problem that prior motor must be joined Lubricating-oil Station, top petrol tank and oil pipe line system.The purpose of this utility model is achieved in that high voltage flameproof high speed self-lubricating threephase asynchronous is made of: support, sliding bearing, oil level compensator, fan, rotor, fan guard and stator.Sliding bearing is installed on the end cap, and is connected with rotor, and stator is contained in the support, is equipped with fan at shaft extension end and non-shaft stretching end, and fan is fixed on the axle, and fan guard covers on the fan, and fan guard and oil level compensator are separately fixed on the support.The oil level compensator of this product can be to sliding bearing repairing, oil extraction under the situation of not dismantling fan, when lubricating oil consumes naturally or oil leakage phenomenon occurs, oil level compensator supply lubricating oil automatically arrives the height of setting, oil level compensator oil reserve can reduce, be convenient in time find and take treatment measures, do not need the user to be equipped with Lubricating-oil Station, top petrol tank and oil circulation system, have installation, inspection, characteristics such as easy to maintenance, be specially adapted to the environmental work that oil, chemical industry, petroleum pipeline, boats and ships etc. have damp.
