Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be further described:

[0023] combine figure 1 , figure 2 As shown, the impeller of this bubble-breaking hybrid transmission submersible pump includes a front cover plate 1, a shaft sleeve 2, a rear cover plate 3, and blades. The blades are segmented blades, and there are bubble-breaking jet slots 8 , the fracture of the bubble breaking jet is disconnected in the span direction of the segmented blade, and the shape is the gap between the trailing edge of the front blade and the leading edge of the rear blade; the front blade 4 is in front of the bubble breaking jet slit 8, and the bubble breaking jet Behind the slot 8 is the rear blade 5 . The fracture of the bubble breaking jet is located between 1 / 3-1 / 2 of the chord distance of the segmented blade, the opening width is 2-5mm, the opening height is the same as the spanwise height of the blade, and the opening is inclined, which is consistent...

Abstract

The invention relates to an impeller of a bubble crushing type hybrid transmission submersible pump. The impeller of the bubble crushing type hybrid transmission submersible pump includes a front cover plate, a shaft sleeve, a rear cover plate and blades. The blades are segmented blades, and the bubble crushing jet The fracture is broken in the span direction of the segmented blade to form a bubble breaking jet slit. The front of the bubble breaking jet slit is the front blade, and the back of the bubble breaking jet slit is the rear blade. The shape of the bubble breaking jet slit is the tail of the front blade. The gap between the edge and the leading edge of the rear blade; there are multiple sets of gas fragmentation jet hole groups on the rear cover, each group of gas fragmentation jet holes is composed of multiple circular holes, and the gas fragmentation jet hole group at the front blade is The jet hole group in the front section, and the jet hole group in the rear section of the blade are the jet hole groups in the back section. The invention can avoid air lock under the condition that the gas content rate reaches 70%, and normally lift the gas-liquid mixture to produce liquid.

Description

Technical field: [0001] The invention relates to a centrifugal impeller used for transporting two-phase abortion fluid with high gas content in a submersible electric pump oil production system, and in particular to a bubble-breaking type mixed transmission submersible pump impeller. Background technique: [0002] With the development of the economy, people's demand for oil is increasing day by day, and the position of oil industry in the whole national economy is becoming more and more important. As oil exploitation enters the middle and later stages, formation energy is gradually consumed, and the extraction method has changed from the initial use of formation energy to lift crude oil to the ground to artificial lift. Artificial lift has become the main method of oil field extraction. Commonly used artificial lift methods are divided into: rod pump oil extraction and rodless pump oil extraction. Rod pump oil production is divided into beam pumping unit oil production and...
