Abstract
The utility model discloses a horizontal centrifugal pump with a cooling water jacket. The horizontal centrifugal pump comprises a pump body, a pump cover and a bearing frame which are successively connected, wherein the pump body is internally provided with an impeller. The horizontal centrifugal pump also comprises a double-layer jacket type seal cavity and a pump shaft, wherein the double-layer jacket type seal cavity is arranged between the pump cover and the bearing frame, and the pump shaft horizontally passes through the double-layer jacket type seal cavity and is connected with the impeller arranged in the pump body; the pump shaft is provided with a mechanical sealing structure, and the mechanical sealing structure is arranged in the double-layer jacket type seal cavity. The horizontal centrifugal pump provided by the utility model has the advantages that the structure is simple; due to the double-layer jacket type seal cavity arranged between the pump cover and the bearing frame, cooling can be completed twice and the cooling effect is good; when a water pump conveys a high-temperature medium, the working temperature in the seal cavity is reduced effectively through the cooling of the double-layer jacket type seal cavity, the airtight performance of the mechanical sealing structure is protected, the service life of the mechanical sealing structure and the bearing is prolonged by multiple times, and the practicability is good.
Description
Technical field
The utility model belongs to the centrifugal pump field of the biochemical dedicated transport high temperature media of food medicine, is specifically related to a kind of horizontal centrifugal pump with cooling water jecket.
Background technique
The horizontal centrifugal pump mechanical sealing chamber of prior art is single layer structure, is about to double mechanical seal and directly is assemblied in the individual layer seal chamber, and when carrying high-temperature material, external cooling water directly enters Seal cage and carries out cooling and lubricating mechanical seal, the heat that is delivered to Seal cage due to high temperature media is more, mechanical seal is moving in addition, stationary ring is during with the impeller High Rotation Speed, friction produces a large amount of heats mutually, depend merely on once cooling (cooling water directly enters Seal cage), cooling mechanical seal parts thoroughly, so just easily cause mechanical seal to move in the hot environment high speed for a long time, moving, the cooling liquid film of stationary ring end face very easily is evaporated, and moving, stationary ring produces thermal distortion, accelerated moving, the wear out failure of stationary ring end face, simultaneously, the o type rubber ring that machine is sealed up is in hot environment also as easy as rolling off a log generation distortion ageing failure for a long time, reduced the working life of mechanical seal, thereby have influence on the whole service life of water pump, practicability is poor.
Summary of the invention
