Double Guide Vane Tubular Oil Pump

Abstract

The invention provides a double-guide vane tubular oil pump, comprising: a pump casing, an inlet bearing seat and an outlet bearing seat are fixedly arranged at the front end and the rear end respectively, and a bearing seat is arranged between the inlet bearing seat and the outlet bearing seat The rotor and the stator; the rotating shaft, which is installed in the inner cavity through the rotation of the bearings on the inlet bearing seat and the outlet bearing seat, the middle part is fixedly connected with the rotor, and the rotating part of the rotating shaft is provided with a plurality of blades, which are fixed There are multiple compression guide vanes on the upper part; the inlet end cover has an oil inlet at the front end, and the rear end is fixedly connected with the pump casing; the outlet end cover is fixedly connected with the pump casing at the front end, and an oil inlet is arranged at the rear end. Oil outlet. The invention adopts the design of the oblique flow impeller, and is provided with a double guide vane structure of compression guide vanes and diversion guide vanes, which can reduce the energy loss of the liquid flow, increase the flow rate and head, and reduce noise pollution.

Description

technical field [0001] The invention relates to the technical field of oil pumps, in particular to a double guide vane tubular oil pump. Background technique [0002] The transformer oil pump is a key component in the operation of electric locomotives. It is a fluid machine that transports transformer insulating oil medium and is mainly used for cooling transformers. At present, there are two types of transformer oil pumps: axial pumps and centrifugal pumps. Among them, the centrifugal oil pump is the main type, and the insulating oil medium used as the cooling liquid is driven by the centrifugal oil pump to circulate to achieve the cooling effect. [0003] Existing centrifugal oil pumps are usually designed in such a way that the medium enters axially and discharges vertically. The oil pumps of this design generally have large dimensions in two directions, which makes the overall structure of the oil pump too large, making it inconvenient to install and optimize the structu...
