Abstract

The invention relates to a plunger pump performance test board used for an ABS (Anti-Lock Break System) pressure regulator. According to the plunger pump performance test board, a testing device comprises a bottom plate, a support rod, oil line connecting pipes, a pressing plate, a guide rod, a lower connecting head, a pressing cylinder, a top plate and a positioning plate; the bottom plate and the top plate are connected by the support rod, and the positioning plate is fixedly arranged on the bottom plate; the pressing cylinder is installed below the top plate, an output shaft of the pressing cylinder is connected with the pressing plate by the lower connecting head, one end of the pressing plate is movably matched with one end of the guide rod, and the pressing plate moves up and down along the guide rod; the other end of the guide rod is fixed on the top plate; and the four oil line connecting pipes are arranged right below the pressing plate and correspond to cavities of a plunger pump to be tested, two of the oil line connecting pipes are taken as output oil line connecting pipes, and the other two oil line connecting pipes are taken as input oil line connecting pipes. The plunger pump performance test board adopts an industrial control computer as a control core, and is matched with a data acquisition card and a sensor to realize the test automation.

Description

technical field [0001] The invention relates to a testing device, in particular to a plunger pump performance testing platform used in a hydraulic ABS system. Background technique [0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize oil absorption and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, and is widely used in high pressure, large flow and flow adjustment occasions, such as hydraulic presses, automotive ABS regulators, engineering machinery and ships. [0003] Now, ABS systems are installed on most automobiles, and the performance of the ABS pressure regulator directly affects the indicators such as ABS braking performance, directional stability, steering ability and minimum braking distance. The automotive hydraulic ABS...
