Abstract

The invention relates to an emulsion pump testing system, comprising an electrical apparatus control system which is used for driving a motor to start or stop, a transmission box connected with a tested pump, an emulsion pump circulating system and a hydraulic oil circulating system for driving the transmission box; the working load of the tested pump is changed by adjusting the discharging amount of an oil hydraulic motor, hydraulic pressure output by the tested pump is compensated to the oil hydraulic motor mostly by a loading cylinder, namely, the oil hydraulic motor is not only a driving force source of the tested pump, but also is a load of the tested pump; the system can carry out reliability detecting test to the emulsion pump with different type and different power, and the comprehensive performance and manufacturing quality of the emulsion pump are detected in an on-line way, therefore, the occupying area of the equipment is not only reduced, but also the operating power can not be converted into heat energy, so as to reduce the operating cost; the most important point is that the power can be recycled, the energy consumption is greatly reduced; compared with the prior art, the energy saving can reach about 70 percent, the structure is simple and energy-saving, and has good using effect.

Description

technical field [0001] The invention relates to a testing system, in particular to an emulsion pump testing system suitable for reliability experiments and comprehensive performance testing of emulsion pumps. Background technique [0002] The emulsion pump is the power component of the support hydraulic system of the coal mine fully mechanized mining face. Its performance and reliability will have an important impact on the entire hydraulic system. Therefore, all emulsion pumps must be tested in an industrial test before use. At present, the comprehensive performance test of the emulsion pump mainly adopts the overflow valve loading method, that is, the emulsification flow pump is driven by a motor to pump the emulsion in the oil tank, and then the test is completed through the adjustment of the overflow valve connected to the oil tank circuit. , although this test device can complete the test work of the emulsification pump, it has the problem of high energy consumption, es...
