Description
Technical field
The present invention relates to fluid pumping field, more special but be not limited to, an improved cooling airflow electric motor drives condensate extractionpump.
Background technique
Condensate extractionpump be used in particular for heating and, filed of air conditioning and many other application, wherein condensation of gas for example is created in when tide or wet appearing at around the air.Must collect and be pumped at a distance from the condensation product (water) that for example freeze in the surface of cooling or the volute of air-conditioning device flows out and handle.Condensate extractionpump generally includes a water tank (wet pit), one detect water tank the condensation water level buoy and be used for the water pump water outlet case to centrifugal pump at a distance by electric motor drive, this electric notor is controlled by this buoy.
Condensate extractionpump often is placed in extreme environment and stands humidity, heat and pollution or dirty.And condensate extractionpump often is installed in and can not arrives thereby the position of maintenance difficult, and therefore reliability for many years is necessary.
For many years, the condensate extractionpump assembly of above-mentioned general model has been used for collecting and the processing condensed water.This unserviced device of a time period that must be operated in is reliably understood too early not working, because unsuitable cooling blast causes the overheated of motor and corresponding buoy control soft copy.Several prior art devices have attempted overcoming this restriction.
This prior art device is to be 6,322,326 the U. S. Patent that is presented to Davis etc. from the patent No..In Fig. 1, the air inspiration ventilation slot that many vertical air are discharged ventilation slot and many levels is arranged on and promotes air ventilation in the motor cover.A turbine air fan, a mouse cage cover (squirrel cage) more particularly is connected to an end of motor, influences air flows, is intended to cool off electric notor.
Another prior art device is 7,252,482 the U. S.
