Description

(54) ЗАЩИТНАЯ ГИЛЬЗА СТАТОРА(54) STATOR PROTECTIVE ELEMENT

Изобретение относитс к герметичным асинхронным электродвигател м с цилиндрическими защитными гильзами статора, предназначенными дл привода насосов, перекачивающих высокоагрессивные окислители.This invention relates to hermetic asynchronous electric motors with cylindrical stator protective sleeves designed to drive pumps pumping highly aggressive oxidizers.

Из основного авт. св. № 248051 известна защитна гильза статора асинхронного электродвигател , выполненна из двух немагнитных цилиндров , в пространстве между которыми установлены чередую1диес магнитопровод щие мостики и полые немагнитные стержни, расположенные напротив пазов статора си.From the main auth. St. No. 248051 is known for the protective sleeve of the stator of an asynchronous electric motor, made of two non-magnetic cylinders, in the space between which there are alternating magnetic conducting bridges and hollow non-magnetic rods located opposite the slots of the stator C.

Недостаток этой гильзы - возможность ее разрушени в результате коррозии или механических повреждений при попадании в зазор между ротором и гильзой посторонних частиц.The disadvantage of this sleeve is the possibility of its destruction as a result of corrosion or mechanical damage when it enters the gap between the rotor and the sleeve of foreign particles.

Цель изобретени - повышение надености гильзы при использовании ее в герметичных электродвигател х дл привода насосов, перекачивающих высокоагрессивные окислители.The purpose of the invention is to increase liner wear when used in sealed electric motors for driving pumps pumping highly aggressive oxidizers.

Указанна цель достигаетс тем, что пространство между немагнитными цилиндрами заполнено нейтральней по отношению к окислителю средой и гидравлически св зано с датчиком давлени . В качестве нейтральной среды может служить фторуглеродиста жидкость. На чертеже изобрс1жен герметичный асинхронный электродвигатель с насосным узлом.This goal is achieved in that the space between the non-magnetic cylinders is filled with a neutral medium with respect to the oxidizer and is hydraulically connected with the pressure sensor. Fluorocarbon liquid can serve as a neutral medium. The drawing depicts a sealed asynchronous electric motor with a pumping unit.

Защитна гильза 1 статора 2 асинхронного электродвигател выполнена из двух немагнитных цилиндров 3 и 4. Пространство А между цилиндрами заполнено чередующимис магнитопровод щими мостиками и полыми немагнитными стержн ми (на чертеже не показаны ) , Цилиндры 3 и 4 выполн ют тонкостенными , из немагнитного материала с высоким удельным электрическим .сопротивлением.The protective sleeve 1 of the stator 2 of the asynchronous electric motor is made of two non-magnetic cylinders 3 and 4. The space A between the cylinders is filled with alternating magnetic bridges and hollow non-magnetic rods (not shown), the cylinders 3 and 4 are thin-walled, of non-magnetic material with high electrical resistivity.

Стержни расположены напротив пи-зов (на чертеже не показаны) статора 2 и выполнены из немагнитного материала-, с высоким удельным сопротивлением. Пространство А между цилиндрами заполнено нейтральной по отношению к окислителю средой, например фторуглеродистой жидкостью, и гидравлически св зано с датчиком 5 давлени . Дл поддержани в пространстве А избыточного давлени нейтральной средыThe rods are located opposite the pushes (not shown in the drawing) of the stator 2 and are made of a non-magnetic material, with high resistivity. The space A between the cylinders is filled with a neutral medium with respect to the oxidizer, such as a fluorocarbon fluid, and is hydraulically connected to the pressure sensor 5. To maintain in space A an overpressure of a neutral medium
