Abstract
The utility model relates to a sewage pump, in particular to a submerged sewage pump. The submerged sewage pump comprises a pump body, a lower bearing is arranged on the pump body, a pump shaft is arranged in the pump body through the lower bearing, an impeller is arranged on the pump shaft, and a liquid outlet pipe is arranged on a liquid outlet of the pump body. The submerged sewage pump is characterized in that a support pipe is arranged above the pump body, a driving motor is mounted at the upper end of the support pipe through a motor base, a middle bearing and an upper bearing are respectively arranged on the middle and the upper portions of the support pipe, a mounting plate is arranged on the lower portion of the upper bearing, a connecting shaft is arranged in the middle bearing and the upper bearing, the lower end of the connecting shaft is connected with the pump shaft, and the upper end of the connecting shaft is connected with the driving motor. The working motor is arranged outside delivered media, a cooling way of the motor is natural air cooling, so a motor bearing is not easy to damage, the motor is not easy to burn down, and accordingly, the sewage pump is applicable to delivery high-temperature media. Without mounting relevant guide rails and fixing devices, the sewage pump is convenient to mount, demount and maintain. The bearing can be cleaned by clean water through a flushing pipe, running stability of a sliding bearing of the pump is guaranteed, namely, running reliability of the sewage pump is guaranteed.
Description
Technical field
The utility model relates to sewage pump, says in detail it is a kind of suitable conveying high temperature media, and motor bearings is not fragile, sewage pump under the liquid that motor is difficult for burning.
Background technique
We know, sewage pump belongs to a kind of of centrifugal impurities pump, and the most normal sewage pump is QW type submerged sewage pump at present, and this sewage pump structure is: be provided with the pump housing, the pump housing is provided with bearing, be provided with pump shaft through bearing in the pump housing, pump shaft is provided with impeller, and pump housing top is provided with submersible motor, motor shaft links to each other with pump shaft, usually motor shaft and pump shaft cast solid are coaxial construction, and the liquid outlet of the pump housing is provided with drain pipe.This sewage pump is when work, and whole pump and motor all are immersed in the medium of conveying, and the cooling of motor relies on fed sheet of a media to cool off, so can not carry high temperature media; Carry high temperature media, cause the motor radiating weak effect, motor bearings is fragile, and motor easily burns; Pump and motor are mounted under water, and installation, maintenance is inconvenient, only have relevant guide rail and dismounting and the maintenance of fixing device guarantee pump and motor are installed, and cost is high; In the fed sheet of a media, during the fed sheet of a media temperature variation, the easy dewfall of motor internal causes motor to burn because of wire short-circuiting because motor submerges; In the motor immersion water, in case reveal, whole pump damages because of burn-down of electric motor simultaneously.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of suitable conveying high temperature media is provided, and motor bearings is not fragile, sewage pump under the liquid that motor is difficult for burning.
The technological scheme that the above-mentioned prior art problem that solves the utility model adopts is:
Sewage pump under a kind of liquid, be provided with the pump housing, the pump housing is provided with lower bearing, be provided with pump shaft through lower bearing in the pump housing, pump shaft is provided with impeller, the liquid outlet of the pump housing is provided with drain pipe, it is characterized in that pump housing top is provided with support tube, the support tube upper end portion is equipped with drive motor through motor cabinet, support tube middle part and top are respectively equipped with intermediate bearing and upper bearing (metal), the upper bearing (metal) bottom is provided with mounting plate, is provided with coupling shaft in intermediate bearing and the upper bearing (metal), and the coupling shaft underpart links to each other with pump shaft, the upper end portion links to each other with drive motor.
Pump shaft described in the utility model and coupling shaft cast solid, simple installation, whole coaxality is high.
Intermediate bearing described in the utility model and lower bearing are provided with the bearing flushing hole, are connected with cleaning hose in the bearing flushing hole.When the molecule in the sewage enters intermediate bearing and lower bearing, can in cleaning hose, inject clear water, bearing is cleaned, simple, convenient, time saving and energy saving.
When the utility model uses, by mounting plate drive motor is installed on the sewage water surface, the pump housing of sewage pump stretches under water, and motor drives pump shaft by coupling shaft and drives sewage pump work.The utility model is because to be in the medium of conveying during machine operation outside, and the type of cooling of motor is the air-cooled of nature, and motor bearings is not fragile, and motor is difficult for burning, and is fit to carry high temperature media; Do not need to install associated guide tracks and fixing device, dismounting and maintenance are convenient.Can use clear water that bearing is cleaned by cleaning hose, guarantee the sliding bearing reliability of operation of pump, namely guarantee reliability of operation.
