Abstract

FIELD: pump engineering . SUBSTANCE: submergible electric pump has a housing provided with pump, electric motor filled with water, sucking passageway with a protecting grid interposed between the pump and motor, pressure passageway, and filter mounted in the pressure passageway on the top end face of the pump shaft. The shaft of the pump and shaft of the electric motor are hollow and interconnected with the axial passageway connected with the inner chamber of the filter and radial openings that are provided in shaft journals and enters the zone of a contact with the bearings. The seal of the pump is made up as a flexible diaphragm secured to the shaft and interacting with the collar mounted inside the housing. EFFECT: enhanced reliability.

Изобретение относится к области насосостроения и может быть использовано преимущественно в погружных насосах, предназначенных для откачивания из скважин жидкости, содержащей твердые механические примеси. Погружной электронасос содержит смонтированные в корпусе насос и водозаполненный электродвигатель, расположенный между ними всасывающий канал с защитной сеткой, нагнетательный канал, фильтр, установленный в нагнетательном канале на верхнем торце вала насоса. При этом вал насоса и вал электродвигателя выполнены полыми с общим осевым каналом, сообщенным с внутренней камерой фильтра и с радиальными отверстиями, расположенными в цапфах валов и выходящими в зону контакта с опорными подшипниками, а уплотнение насоса выполнено в виде закрепленной на валу эластичной диафрагмы, взаимодействующей с установленной в корпусе манжетой и "раскрывающейся" под действием избыточного давления жидкости, которая поступает по осевому каналу в полость водозаполненного электродвигателя.The invention relates to the field of pump engineering and can be used mainly in submersible pumps designed to pump out liquids containing solid solids from wells. The submersible electric pump contains a pump mounted in the housing and a water-filled electric motor, a suction channel with a protective grid located between them, a discharge channel, a filter installed in the discharge channel at the upper end of the pump shaft. In this case, the pump shaft and the motor shaft are hollow with a common axial channel in communication with the filter inner chamber and with radial holes located in the shaft pins and extending into the contact area with the thrust bearings, and the pump seal is made in the form of an elastic diaphragm fixed to the shaft, interacting with a cuff installed in the casing and “opening” under the action of excess liquid pressure, which enters the cavity of the water-filled electric motor through the axial channel.
