Abstract
The invention provides an equipment for collecting and discharging centrifugal pump shaft seal leakage liquid and comprises a centrifugal pump, a bearing bracket provided with a bearing whose inner part is provided with a pump shaft, a pump cover arranged on one side of the bearing bracket, and a shaft seal arranged between the pump cover and the pump shaft. The lower part of the cavity formed by combining the pump cover and the bearing bracket is provided with a leakage liquid catch tray whose lower part is provided with a discharge opening. When toxic media with corrosivity are conveyed, leakage media are gathered to the leakage catch tray at the lower part of the cavity formed by combining the pump cover and the bearing bracket, and are discharged to the outside of the pump body through the discharge opening. The equipment can prevent the leakage media from corroding parts such as the pump cover, the bearing bracket, etc., avoid corroding local slits and destroying structural stability of integral structure of the pump body, thus being suitable for various liquid pumps.
Description
Technical field
The present invention relates to centrifugal pump, is that a kind of centrifugal pump seal leakage fluid is collected, tapping equipment specifically.
Background technique
We know, existing centrifugal pump is to be provided with bearing on bearing bracket stand, is provided with pump shaft in the bearing, and bearing bracket stand one side is provided with pump cover, are provided with axle envelope between pump cover and the pump shaft, and during centrifugal pump work, axle is sealed the leakage in various degree up for safekeeping.This centrifugal pump is because axle is sealed the leakage in various degree up for safekeeping, when conveying has corrosivity, poisonous medium, the medium that leaks out gathers the cavity bottom that pump cover and bearing bracket stand are combined into, parts such as corrosion pump cover, bearing bracket stand cause the partial aperture corrosion, destroy pump overall structure stability.
Summary of the invention
The technical problem that the present invention solves is, solve to carry and have corrosivity, during poisonous medium, the medium that leaks out gathers the cavity bottom that pump cover and bearing bracket stand are combined into, the corrosion pump cover, parts such as bearing bracket stand, cause the partial aperture corrosion, destroy the problem of pump overall structure stability, provide a kind of conveying to have corrosivity, during poisonous medium, the medium that leaks out gathers the cavity bottom that pump cover and bearing bracket stand are combined into, do not corrode pump cover, parts such as bearing bracket stand, avoid causing the partial aperture corrosion, prevent to destroy the centrifugal pump seal leakage fluid collection of pump overall structure stability, tapping equipment.
Technological scheme of the present invention is that bearing bracket stand is provided with bearing, is provided with pump shaft in the bearing, bearing bracket stand one side is provided with pump cover, is provided with the axle envelope between pump cover and the pump shaft, and the main structure characteristics are, the cavity bottom that pump cover and bearing bracket stand are combined into is provided with the leakage fluid catch tray, and the catch tray bottom is provided with floss hole.
Floss hole of the present invention is provided with flange
The invention has the beneficial effects as follows, because the cavity bottom that pump cover and bearing bracket stand are combined into is provided with the leakage fluid catch tray, the catch tray bottom is provided with floss hole, when conveying has corrosivity, poisonous medium, the medium that leaks out gathers in the cavity bottom leakage fluid catch tray that pump cover and bearing bracket stand be combined into, and is discharged into outside the pump housing by floss hole, does not corrode parts such as pump cover, bearing bracket stand, avoid causing the partial aperture corrosion, prevent to destroy pump overall structure stability.The present invention is applicable to various liquid pumps.
Description of drawings
Accompanying drawing is a kind of structural representation of the present invention, also is a kind of embodiment's schematic representation.
Embodiment
Centrifugal pump seal leakage fluid is as shown in the figure collected, tapping equipment, bearing bracket stand 2 is provided with bearing, be provided with pump shaft in the bearing, bearing bracket stand 2 one sides are provided with pump cover 6, be provided with axle envelope 4 between pump cover 6 and the pump shaft, pump cover 6 is provided with leakage fluid catch tray 3 with the cavity bottom that bearing bracket stand 2 is combined into, catch tray 3 bottoms are provided with floss hole 5, conveying has corrosivity, during poisonous medium, the medium that leaks out gathers in the cavity bottom leakage fluid catch tray 3 that pump cover 6 and bearing bracket stand 2 be combined into, and is discharged into outside the pump housing by floss hole 5, does not corrode pump cover 6, bearing bracket stand 2 parts such as grade, avoid causing the partial aperture corrosion, prevent to destroy pump overall structure stability.The floss hole place is provided with flange, can connect discharge pipe, and discharging is convenient.
