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.
