Abstract
The utility model provides a novel postposition bulb tubular pump and belongs to the technical field of pump station devices. The novel postposition bulb tubular pump is composed of a water inlet channel, an impeller, guide vanes, a bulb body, a supporting pier, a water outlet channel and the like, wherein the water inlet channel, the impeller, the guide vanes and the water outlet channel are connected in sequence, the bulb body is arranged in the water outlet channel through the supporting pier, the tail portion of the bulb body is of an oval shape, the supporting pier is of a streamline type, and a kidney-shaped outer shell form is adopted in the middle portion of the water outlet channel. According to the novel postposition bulb tubular pump, the streamline-type supporting pier is adopted, and hydraulic loss is effectively reduced. The flow separation area of the tail portion of the bulb body is effectively compressed by the adoption of an oval-shaped bulb body structure, and the flow return area behind the tail portion of the bulb body is compressed in a relatively small area. The technical theory of the kidney-type outer shell of the water outlet channel is based on the theory of flow speed homogeneous diffusion in flow channels, and hydraulic loss increase due to the sudden reduction of flow speed is avoided. Compared with a traditional tubular pump device, the novel postposition bulb tubular pump greatly reduces the hydraulic loss of output water, effectively improves efficiency and saves energy resources.
Description
Technical field
The utility model relates to the bulb through-flow pump, and particularly rearmounted bulb through-flow pump structure form belongs to pumping plant device technique field.
Background technique
Through-flow pump has characteristics such as lift is low, flow is big, horizontal layout, set structure compactness as the pump type that adapts to than low lift, has that runner is straight, hydraulic loss is little, the unit efficiency advantages of higher.Be divided into bulb through-flow pump, silo infusion pump and shaft extension formula through-flow pump etc. in the through-flow pump form again.After at present put into operation in the domestic through-flow pumping plant of having built such as three stations, Huaian, Jiangsu, there was problem such as start that success rate is low, motor overpower, unit efficiency are not high in unit, failed to reach the level of former experimental study achievement.Deep studies show that, tubular pump is except the good impeller outer of needs, and device runner especially water flowing out structure has considerable influence to the whole hydraulic performance of pumping plant.But present tubular pump is difficult to reach high efficiency and the little target of hydraulic loss of expection.
The model utility content
The purpose of this utility model is exactly the deficiency that exists at above-mentioned existing bulb through-flow pump, solve the big problem of through-flow pump outlet passage hydraulic loss, provides a kind of structural type simple, a kind of novel rearmounted bulb through-flow pump that the pump-unit whole efficiency is high.
The purpose of this utility model is to realize like this, a kind of novel rearmounted bulb through-flow pump, comprise water inlet flow channel, impeller, stator, bulb, support pier, outlet passage, water inlet flow channel, impeller, stator, outlet passage connect successively, bulb is arranged in the outlet passage by support pier, it is characterized in that, described bulb afterbody is ellipse, support pier is streamlined, and the shell form of receiving the waist type is adopted at the outlet passage middle part.
Described disciform transverse is 1.2 with the minor axis ratio.
The length of described support pier is 5.2 with the ratio of thickness.
Described outlet passage is made by metallic material and is constituted.
Described support pier is the metal hollow structure.
Described bulb is double structure, is made of Metal Material Welding.
The utility model is rational in infrastructure simple, adopts the know-why of streamlined support pier to be based on least energy consumption principle, effectively reduces hydraulic loss.Adopted the know-why of ellipse bulb structure to be based on the separation of flow district that this structure has effectively been compressed the bulb afterbody, the recirculating zone behind the bulb afterbody is compressed in the less zone.The know-why of receiving the outlet passage shell of waist type is based on the even diffusion principle of flow velocity in the runner, and the hydraulic loss of avoiding the unexpected minimizing of flow velocity to cause increases.The utility model is with respect to traditional tubular pump, and a kind of water outlet hydraulic loss of novel rearmounted bulb through-flow pump reduces greatly, has improved unit efficiency effectively, has saved the energy.
