| Abstract: | This paper presents the study on testing system for the performance of hydraulic pumps for crop protection equipment. The testing system consists of industrial computer ,signal-collecting cards and several kinds of sensors ( two pressure sensors, one flow-rate sensor, one torque sensor and one rotate speed sensor ) . It is in high automatic level ,testing precision and working efficiency and can be widely used on the facility for testing the performance of hydraulic pumps for crop protection equipment. |
