Abstract

The invention relates to the technical field of electronic component processing equipment, in particular to a bi-rotor oil pump. Good lubrication of an engine can still be ensured when the engine is tilted by a certain angle. The oil pump includes a pump body and a pump cover, two separate rotor cavities are formed in the pump body, and a main pump rotor and an auxiliary pump rotor are arranged in the rotor cavities respectively; a main pump oil suction port, a main pump oil drain outlet, a secondary pump oil suction port and a secondary pump oil drain outlet are formed in the pump cover, wherein the main pump oil suction port is connected with a left side oil pipe at the bottom of an oil bottom shell, the main pump oil drain port is communicated with a main oil channel of the engine, the secondary pump oil suction port is connected with a right side oil pipe at the bottom of the oil bottom shell, the secondary pump oil discharge port is communicated with the oil bottom shell on one side of the main pump oil suction port, driven gears are fixedly arranged at the shaft end of the main pump rotor and the shaft end of the secondary pump rotor, and the driven gears are driven by a crankshaft of the engine.
