The reciprocating pump is an important device in underground coal mine production, and comprises a crankcase and a hydraulic end of the emulsion pump, wherein the crankcase bears a transmission function, the lubricating oil power of the whole crankcase is provided by a gear oil pump, and the power input of the gear oil pump is derived from the motor input of the reciprocating pump. Along with the energy-saving concept going deep into the coal mine industry, the reciprocating pump motor starts to be converted from the power frequency motor to the variable frequency motor, and the flow and the pressure of the gear oil pump can not meet the original lubricating system requirements along with the change of the transmission speed after the variable frequency motor is adopted, so that a group of motors and the gear oil pump are additionally added in the system for standby, and the condition of unstable oil pressure is caused. Because the rotating speed of the variable frequency motor is unstable, when the rotating speed of the motor is small and the gear oil pump on the pump can not meet the lubricating requirement of the lubricating system, the control system sends out a command at the moment, the external oil pump is started, and the lubricating oil quantity of the external oil pump and the flow of the gear oil pump at the original pump end are far more than the requirement of the lubricating system; when the rotating speed of the variable frequency motor is increased, the oil quantity of the lubrication system is larger for a part of time due to delay.
