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, the test of excavator fuel consumption efficiency adopts following form substantially: it is smooth that excavator will excavate medium before test, after machine entirety to be excavated debugging steadily, and dig pit 90 °, the 180 ° sides of getting rid of or car loading operation.Between digging machine operational period, record respectively Excavating bucket number and time by tester, after the end of job, measure fuel consumption, work efficiency and the oil consumption of calculating excavator with this.
According to the difference of field by using metering oil consumption mode, fuel consumption efficiency method of testing can be divided into two kinds of modes: 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 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 test, utilizes measuring cup top off again after test, reads the amount of fuel that the record of measuring cup number scale adds fuel tank.The test data error ratio producing because of the second method of testing is larger, conventionally adopts the external fuel tank weight method of the first.
