Oil pump testing system for engine

The utility model provides an oil pump testing system for an engine. The oil pump testing system for the engine comprises a control module, a power module, a rotation speed torque sensor, a main oil tank, an oil pump clamp, an oil pump oil discharging pressure sensor, an oil pump oil discharging temperature sensor, a first valve, a first flow sensor and a first proportional valve. The power module is connected with the rotation speed torque sensor and the oil pump clamp to form a one-way loop. The main oil tank is connected with the oil pump clamp, the oil pump oil discharging pressure sensor, the oil pump oil discharging temperature sensor, the first valve, the first flow sensor and the first proportional valve in sequence through oil pipes to form a closed loop. According to the oil pump testing system for the engine, the components for testing different performance parameters of an oil pump are organically integrated through the reasonable pipeline design, the oil pump performance testing process can be automatically controlled, no specially-assigned person is needed to be on duty, operation is convenient, and the work efficiency is effectively improved.
