Problems solved by technology

[0004] But the disadvantage of the existing technology is that there is no equipment dedicated to the durability test of the oil pump. The data records of the durability test of the traditional oil pump are all recorded by handwriting, and the tester needs to regularly check the working voltage and the working current of the oil pump.

Abstract

The invention discloses a durability test system for an oil pump and a test method of the test system. The durability test system is characterized in that the control end of a master control chip of the durability test system for the oil pump is connected with the grid electrode of a field-effect transistor; the current detection end of the master control chip is connected with the source electrode of the field-effect transistor; the source electrode is connected with a current detection resistor in series and then is earthed, and the drain electrode of the field-effect transistor is connected with an oil pump socket; and the master control chip is provided with a voltage detection end which is earthed via a lower divider resistance and is connected with an oil pump power supply via an upper divider resistance. The system disclosed by the invention has the following effects: the working voltage and working current of the oil pump can be detected within 24hours ceaselessly, the accuracy and reliability are better as compared with artificial detection, and the revolving speed of the oil pump can be controlled as required to adapt to detection requirements under different working states.

Description

technical field [0001] The invention belongs to an oil pump detection technology, in particular to an oil pump durability test system for motorcycles and a test method thereof. Background technique [0002] The function of the oil pump is to send the fuel in the fuel tank to the engine. During the whole driving process, the oil pump is working under load, so the service life of the oil pump is very critical. [0003] Therefore, it is necessary to carry out a durability test on each oil pump before it is installed. [0004] But the shortcoming of prior art is: there is not a kind of equipment dedicated to the durability test of oil pumps yet, the data record of the durability test of traditional oil pumps is all to be recorded by handwriting and needs the tester to detect the working voltage and the working current of the oil pump on a regular basis. Contents of the invention [0005] The problem to be solved by the present invention is to provide an oil pump durability te...
