System and method for testing fuel consumption and efficiency of excavator

Abstract

The invention provides a system and method for testing fuel consumption and efficiency of an excavator and belongs to the technical field of construction machinery manufacturing. The system comprises an excavator 1, a testing position 2, a testing medium 3, a first medium container 4 and an oil volume measurer 5, wherein the excavator 1 comprises an oil tank 11 and an engine 12 which are connected with each other; the excavator 1 is placed in the testing position 2; the first medium container 4 is a container with one end being opened; the testing position 2 and the opening of the first medium container 4 are located on a same plane; a distance between the testing position 2 and the opening of the first medium container 4 is 2-35m; the testing medium 3 is arranged in the first medium container 4; and the oil tank 11 of the excavator 1 is connected with the engine 12 through the oil volume measurer 5. The medium container is adopted by the system provided by the invention, so that the excavating medium can be quickly exchanged and the test for multiple working conditions is performed. The oil volume measurer is used for gauging the oil volume, so that the accuracy of tested data is increased, the labor intensity of personnel is reduced, the tester is reduced and the test efficiency is increased.

Description

technical field [0001] The invention belongs to the field of machinery manufacturing, and relates to a fuel consumption efficiency testing system and method, in particular to an excavator fuel consumption efficiency testing system and method. Background technique [0002] At present, the fuel consumption efficiency test of an excavator basically adopts the following form: the excavator will level the excavation medium before the test, and after the overall debugging of the excavator is stable, the digging operation will be carried out at 90°, 180° or loaded. During the operation of the excavator, the testers record the number of buckets and the time, and measure the fuel consumption after the operation, so as to calculate the working efficiency and fuel consumption of the excavator. [0003] According to the different ways of measuring fuel consumption on site, the fuel consumption efficiency test method can be divided into two methods: one is the external light fuel tank w...

AI Technical Summary

Problems solved by technology

[0004]Before the present invention, the inventor found at least the following problems in the prior art: 1) The test error is relatively large: during a single test, due to test personnel, weather, stop position Factors such as the influence of the test data produce errors

During the test, there was an error in the timing part of the personnel; when measuring the fuel consumption, the test personnel controlled unbalanced refueling or the wind speed was too high, causing part of the fuel to spill, which had a great impact on the test data;

[0005]2) Low efficiency of personnel: due to cumbersome testing work such as recording the number of buckets, timing, weighing fuel or recording the number of measuring cups

During the test period, many people need to cooperate with each other to complete the test, and there are many staffs, and the personnel efficiency is low;

[0006]3) Single working condition: limited by the soil quality of the excavation test site, the selectivity of a single excavation medium is poor;

[0007]4) The test efficiency is low: the test time interval is relatively long, during which the test personnel weigh the fuel, refuel and other related work takes a long time;

[0008]5) The accumulated data has low comparability: the data of the fuel consumption efficiency test before and after is affected by the weather, testers, working conditions, test methods and operators, etc., resulting in The test data gap is large and the comparability is low
