Description

technical field [0001] The invention belongs to the technical field of hydraulic pump detection, and in particular relates to a comprehensive performance test system suitable for four-quadrant hydraulic pumps. Background technique [0002] In industrial production and daily life, hydraulic systems are widely used. In hydraulic systems, hydraulic pumps and hydraulic motors often play a very important role. Among them, the hydraulic pump is the power component of the hydraulic system, which is often driven by the engine or electric motor, sucks the oil from the hydraulic oil tank, forms pressure oil and sends it to the actuator; and the hydraulic motor is an actuator of the hydraulic system. The hydraulic pressure provided by the hydraulic pump can be transformed into the mechanical energy (torque and rotational speed) of its output shaft to correspondingly drive the corresponding components to complete the corresponding process. [0003] Traditionally, the hydraulic motor a...
