Abstract

The invention relates to horizontal testing equipment for an oil pump. The horizontal testing equipment comprises a rack, a clamp system, a power system, a pipeline system and a detection system, the power system is connected with and transmits torque to the clamp system, the oil pump is mounted on the clamp system, the pipeline system is connected on the oil pump, the detection system is mounted on the pipeline system for detection, the clamp system comprises an adjusting support, a transmission shaft and a testing plate, the transmission shaft penetrates the adjusting support, one end of the transmission shaft is connected to the power system while the other end of the same penetrates the testing plate, and a main gear is mounted at the other end of the transmission shaft; the oil pump is mounted on the testing plate, an auxiliary gear is mounted on the oil pump, the main gear is meshed with the auxiliary gear to form a gear member which is made by carbon-tempered steel, the oil pump is close to and sealed on the testing plate, an oil incoming hole and an oil outgoing hole which are communicated to the oil pump are formed in the testing plate, and the pipeline system is connected on inlets of the oil incoming hole and the oil outgoing hole respectively. The horizontal testing equipment is simple in structure, convenient in testing, accurate in testing 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...
