Description
Technical field
The invention belongs to mechanical manufacturing field, relate to a kind of fuel consumption efficiency test macro and method, relate in particular to a kind of excavator fuel consumption efficiency test macro and method.
Background technology
At present, following form is adopted in the test of excavator fuel consumption efficiency basically: excavator will excavate medium before test smooth, after the whole debugging steadily of machine to be excavated, and dig pit 90 °, the 180 ° sides of getting rid of or car loading operation.Record respectively Excavating bucket number and time by the tester between the digging machine operational period, measure fuel consumption after the end of job, calculate work efficiency and the oil consumption of excavator with this.
Difference according to field by using metering oil consumption mode, the fuel consumption efficiency method of testing can be divided into dual mode: a kind of mode is the external lightweight fuel tank method of testing of weighing, utilize electronic scale to measure the weight of operation front and back lightweight fuel tanks (containing fuel oil), calculate the single operation oil consumption with the difference of the two; Another kind of mode is to utilize excavator self fuel tank, and top off before the test utilizes again top off of measuring cup after the test, reads the amount of fuel that the record of measuring cup number scale adds fuel tank.The test data error ratio that produces because of the second method of testing is larger, usually adopts the external fuel tank weight method of the first.
