Problems solved by technology

At present, although there are energy-saving test methods using power recovery, they are all for a single pump, and the energy-saving effect is not ideal
For double, triple or quadruple gear pumps, because the rated pressure and flow rate of each pump are not exactly the same, the existing energy-saving test methods are not applicable

Abstract

The invention discloses a multiplex gear pump energy-saving testing bench suitable for performance testing and reliability checking on various multiplex gear pumps, and relates to a testing bench. The multiplex gear pump energy-saving testing bench comprises a tested multiplex gear pump, loading elements, a synchromesh gearbox, power compensating components, testing elements, self-circulation filtering cooling devices and an oil tank. According to the multiplex gear pump energy-saving testing bench, the synchromesh gearbox is mechanically connected with loading hydraulic motors through the tested multiplex gear pump, the loading hydraulic motors are power and loads of the tested multiplex gear pump at the same time, power compensation is achieved through volume compensating pumps and a mechanical compensating motor, and power recovery is overall achieved. The multiplex gear pump energy-saving testing bench is simple in structure, good in power recovery effect and high in use reliability and practicability.

Description

technical field [0001] The invention relates to a test bench, in particular to a multi-connected gear pump energy-saving test bench suitable for performance testing and reliability assessment of various multi-connected gear pumps. Background technique [0002] Duplex, triple or quadruple gear pump performance test and reliability assessment need to be carried out on the test bench. Existing test benches are fully loaded with overflow and throttling methods, and almost all the energy output by the motor is converted into heat energy. On the one hand, this makes the test consume a lot of energy. On the other hand, it is necessary to add a cooling device due to the heat of the oil. , and additional power consumption is required. Especially when carrying out high-pressure and high-flow tests, the energy consumption is very large. At present, although there are energy-saving test methods using power recovery, they are all carried out for a single pump, and the energy-saving eff...
