Abstract
A deep well water pump system has a temperature probe (17) in the air space above the top bearing (12), preferably in the oil inlet chamber (26), and provides means for signalling abnormal temperatures to warning and system shutdown means. A method of detecting bearing overheating indirectly by sensing the shaft temperature and/or the temperature in the enclosed air space above the bearing is disclosed.
Claims20
In combination with a deep well water pump system having:
- a column pipe for water flow;
- an oil tube concentrically disposed within the pipe;
- a pump shaft concentrically disposed within the tube;
- bearings around said shaft whereby an air space which communicates with an oil inlet chamber having an air space therein is maintained around said shaft;
- and a motor to operate said pump shaft between said bearings;
- a warning device for detecting the overheating of a bearing, comprising:
- a temperature probe disposed in the air space above the first bearing in said oil tube for indirectly detecting a rise in temperature in the bearings, and means for signalling a rise in temperature to a predetermined maximum value.
A deep well water pump system comprising:
- a column pump for water flow, an oil tube concentrically disposed within the pipe, a pump shaft concentrically disposed within the tube, bearings around said shaft, whereby an air space which communicates with an oil inlet chamber having an air space therein is maintained around said shaft, motor means for rotating the shaft above the topmost bearing, and a warning device for detecting temperatures in said shaft related to the overheating of said bearings comprising a temperature probe disposed in said air space above in close proximity to said shaft and means for signalling a rise in temperature to a predetermined maximum value.
A method for detecting bearing overheating in a deep well water pump system having:
- a column pipe for water flow, an oil tube concentrically disposed within the pipe, a pump shaft concentrically disposed within the tube, bearings around said shaft, whereby an air space which communicates with an oil inlet chamber having an air space therein is maintained around said shaft between and above said bearings;
- the step of detecting the overheating of said bearings indirectly by measuring the temperature in the air space above the top bearing in said oil tube.
A deep well water pump system comprising:
- a column pump for water flow, an oil tube concentrically disposed within the pipe, a pump shaft concentrically disposed within the tube, bearings around said shaft, whereby an air space which communicates with an oil inlet chamber having an air space therein is maintained around said shaft, motor means for rotating said shaft above the topmost bearing,.and a warning device for detecting temperatures in said air space shaft related to the overheating of said bearings comprising means for remotely sensing the temperature of said shaft, and means for signalling temperature of a predetermined maximum value.
