Abstract

The invention provides a novel system for testing fuel consumption of an excavator, a novel system for testing working efficiency of an excavator, and methods. The novel system for testing fuel consumption of the excavator comprises a controller and a fuel level detector connected with the controller, wherein the fuel level detector is used for detecting fuel level data of a to-be-detected fuel tank and transmitting the fuel level data to the controller; and the controller processes the fuel level data and then acquires fuel consumption data. The system for testing the working efficiency of the excavator comprises a controller, and a fuel level detector, an angle detector and a memory which are connected with the controller. By adopting the systems and the methods, the labor cost of detecting the fuel consumption of the whole machine by a manufacturer before a new machine type is issued each time is reduced, the detection efficiency is greatly improved, the test error is reduced, and the test accuracy degree is improved.

Description

technical field [0001] The invention relates to a novel excavator oil consumption test system and method, and an excavator working efficiency test system and method. Background technique [0002] As the country pays more and more attention to energy saving and emission reduction, excavator manufacturers must first test the fuel consumption and working efficiency of the whole machine before releasing a new model. However, the current test system relies on too much manpower, and the differences in tests by different testers are large, and the fuel consumption meters on the market are expensive. [0003] In the existing fuel consumption and work efficiency testing technology, the fuel consumption is an external independent oil tank, and the fuel consumption is calculated by the weight of the oil tank before and after the test, which is inconvenient to operate and has large errors. [0004] The number of buckets of the excavator also needs to be recorded manually, which is labo...
