Description

Technical Field

[0001] The utility model belongs to the technical field of pump casing dimple cleaning, in particular to a pump casing dimple cleaning device. Background Art

[0002] There are two types of pump casings: axially split and radially split. Most single-stage pump casings are volute-type, and the radially split casings of multistage pumps are generally annular or circular. The inner cavity of the volute-type pump casing is generally a spiral liquid channel, which is used to collect the liquid thrown out from the impeller and lead it to the diffuser to the pump outlet. The pump casing bears all the working pressure and the heat load of the liquid.

[0003] The location in the pump casing for placing and installing the impeller is called the socket. In the production process of chemical fiber yarn, various pumps are used, such as feed pumps for conveying raw materials and water pumps for conveying liquids. Regardless of feed pumps or water pumps, most of them have the problem of small space in the socket and bending channels in the pump casing, which makes it extremely inconvenient to clean the socket of the pump casing.

[0009] In one example, the lifting assembly includes a vertical plate, which is fixedly connected to the workbench. A square through groove is provided on one side of the vertical plate. A sliding seat is slidably connected in the square through groove. One side of the sliding seat is fixedly connected to a horizontal plate. The clamping assembly is located on the lower surface of the horizontal plate. One side of the vertical plate is fixedly connected to an electric push rod. The telescopic rod of the electric push rod is fixedly connected to the sliding seat.

[0013] The pump casing cavity cleaning device proposed by the utility model can bring the following beneficial effects:

[0014] First, by setting a circular cylinder, the downward channel of the pump casing is against the support plate and aligned with the spray hole. At the same time, the pump casing is already in the cleaning liquid. The pump casing continues to descend, and the support plate pushes the extrusion plate down. The extrusion plate squeezes the cleaning liquid inside. The cleaning liquid enters the pump casing through the circular through hole, vertical pipe and spray hole on the extrusion plate, flushes the cavity position where the impeller is installed inside the pump casing, and cleans the area near the cavity of the pump casing to avoid difficulty in cleaning due to the narrow space near the cavity.

[0015] Secondly, by providing a spiral groove and a protrusion, when the pump casing descends, the spring is compressed, and when the extrusion plate descends, the protrusion slides along the spiral groove, causing the extrusion plate to spirally descend, driving the support plate to rotate, stirring the water flow, and cleaning the outside of the pump casing. When the lifting assembly drives the pump casing to rise, the spring is reset, the support plate rises, and the extrusion plate spirally rises accordingly. The cleaning liquid enters the pump casing through the channel on one side of the pump casing, passes downward through the vertical pipe through a channel perpendicular to the pump casing and enters the circular cylinder to replenish the cleaning liquid in the circular cylinder. At the same time, when the cleaning liquid passes through the pump casing in reverse, the pump casing groove is cleaned again, thereby improving the cleaning effect on the side wall of the pump casing groove.
