Abstract
Some implementations include a method for controlling lubrication of a hydraulic fracturing pump. The method may include pumping, via an electric motor and lubrication pump, lubrication oil through the hydraulic fracturing pump at a first flowrate. The method may include increasing flow of the lubrication oil to a second flowrate in response to a detected increase in temperature and/or drop in viscosity of the lubrication oil.
Claims23
A method for controlling lubrication of a hydraulic fracturing pump, the method comprising:
- pumping, via an electric motor and lubrication pump, lubrication oil through the hydraulic fracturing pump at a first flowrate;
- and
- increasing flow of the lubrication oil to a second flowrate in response to detecting that a temperature of the lubrication oil is over a temperature threshold or a reduction in current drawn by the electric motor or a decrease in pressure.
One or more machine-readable mediums including instructions that, when executed by a processor, for controlling lubrication of a hydraulic fracturing pump, the instructions comprising:
- instructions to pump, via an electric motor and pump, lubrication oil through the hydraulic fracturing pump at a first flowrate;
- and
- instructions to increase flow of the lubrication oil to a second flowrate in response to a detected increase in temperature and/or drop in viscosity of the lubrication oil.
An apparatus comprising:
- a processor;
- one or more machine-readable mediums including instructions that, when executed by the processor, for controlling lubrication of a hydraulic fracturing pump, the instructions comprising
- instructions to pump, via an electric motor and pump, lubrication oil through the hydraulic fracturing pump at a first flowrate;
- and
- instructions to increase flow of the lubrication oil to a second flowrate in response to a detected increase in temperature and/or drop in viscosity of the lubrication oil.
