20140232226 | HIGH CONICAL ANGLE TOUCH DOWN BEARING - A machine comprises a rotor ( | 08-21-2014 |
20130294931 | PUMP SYSTEM - Disclosed is a system for controlling a pump, such as a submersible pump intended for pumping water, including a pump and a separate electronic control unit connected to the pump by an electrical cable. The control unit is adapted to be detachably connected to the pump, by that the control unit is adapted to allow the pumps power supply to pass through the control unit, by that an electronic controller is arranged in the pump for controlling at least one of the pump's functions and/or monitoring at least one of the pump's operating conditions, and by that the pump and the control unit are adapted to communicate with each other and transmitting signals, including necessary control and/or monitoring information/data, between each other. | 11-07-2013 |
20130209218 | TURBOMACHINE - A method for obtaining an estimate for a process quantity of a turbomachine comprises measuring ( | 08-15-2013 |
20130177450 | CONTROL OF A PUMP DEVICE - A method of controlling a pump device for discharging fluid, wherein the method comprises the steps of providing a heat portion adapted to be thermally coupled to the fluid to allow heat transfer there between when the fluid is at or above a certain level; monitoring a temperature parameter reflecting a temperature of the heat portion, the temperature parameter including a temperature value of the temperature of the heat portion; calculating a cooling rate value (CRV), the calculation including a comparison between at least two temperature values measured at different times; performing a pumping operation analysis including a comparison between a present cooling rate value (CRV) and a reference cooling rate value (ref), the reference cooling rate value representing a specific cooling rate of the heat portion; and initiating pumping operation to discharge the fluid if the cooling rate value is equal to or exceeds the reference cooling rate value. | 07-11-2013 |
