Abstract

The invention relates to horizontal test equipment for an oil pump. The horizontal test equipment comprises a rack, a clamp system, a power system, a pipeline system and a detection system, wherein the power system is connected with the clamp system and transmits torque to the clamp system; the oil pump is mounted on the clamp system, and the pipeline system is connected onto the oil pump; a detection system is mounted on the pipeline system and used for detection; the clamp system comprises an adjusting bracket, a drive shaft and a test board, the drive shaft penetrates through the adjusting bracket, one end of the drive shaft is connected to the power system, the other end penetrates through the test board, and a main gear is mounted at the end part, and the drive shaft is made by carbon tempered steel; the oil pump is mounted on the test board, provided with an auxiliary gear meshed with the main gear and tightly attached and sealed on the test board; oil inlet holes and oil outlet holes communicated with the oil pump are formed in the test board; and the pipeline system is connected to entrances of the oil inlet holes and the oil outlet holes respectively. The test equipment is simple in structure, convenient to test, accurate in detection performance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of testing machinery, and relates to a testing device, in particular to a horizontal testing device for an oil pump. Background technique [0002] The oil pump refers to the device that can force the oil from the oil pan to the moving parts of the engine in the lubrication system. When the engine is working, the driving gear on the camshaft drives the transmission gear of the oil pump, so that it is fixed on the driving gear shaft. The driving gear rotates, thereby driving the driven gear to rotate in the opposite direction, and the oil is sent from the oil inlet chamber to the oil outlet chamber along the tooth gap and the pump wall. In this way, a low pressure is formed at the oil inlet chamber to generate suction, and the oil in the oil pan is sucked into the oil chamber. Due to the continuous rotation of the main and driven gears, the oil is constantly pressed to the required parts. [0003] Chinese pa...
