Abstract
The invention relates to an energy-saving detection system for a hydraulic pump. The energy-saving detection system comprises a motor, the to-be-detected hydraulic pump, a pressure sensor, a flow sensor and an oil tank. A right-angle speed reducer and a 3:1 speed reducer are sequentially connected between the motor and the to-be-detected hydraulic pump through couplings; a gear pump is connected to the other output end of the right-angle speed reducer; and a conversion plate is coaxially connected between the couplings and the to-be-detected hydraulic pump. According to the energy-saving detection system, the motor of 30 kw, the right-angle speed reducer, the 3:1 speed reducer, the gear pump and a cooler form the core of the energy-saving low-cost hydraulic pump test system. According to the layout mode, a cooling fan of the motor is fully used for providing an air source for the cooler, and accordingly the temperature of the hydraulic system is controlled. In addition, enough starting torque is supplied to the to-be-detected hydraulic pump by the 3:1 speed reducer, a motor of 110 kw is omitted, and accordingly the energy-saving effect is significant.
