Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the drawings and embodiments, but the protection scope of the present invention should not be limited accordingly.

[0029] The invention is used to calibrate the accuracy of the fuel consumption measuring equipment used in the test run of the main engine. The fuel consumption measuring equipment includes a fuel supply pipeline flowmeter, a fuel return pipeline flowmeter and a fuel consumption measuring instrument. The fuel supply pipeline flowmeter is connected to On the main fuel input pipe, the oil return pipeline flowmeter is connected to the fuel main output pipe, and the fuel consumption measuring instrument is respectively connected to the fuel supply pipeline flowmeter and the fuel return pipeline flowmeter.

[0030] see figure 1 , the present invention connects the oil supply pipeline flowmeter 4 and the oil return pipeline flowmeter 5 connected in series into the calibration lo...

Abstract

According to the method for verifying precision of oil consumption measuring equipment. The oil consumption measuring equipment comprises an oil supply pipeline flowmeter, an oil return pipeline flowmeter and an oil consumption measuring instrument, and according to the verification method, an oil pump is adopted for supplying oil to the oil supply pipeline flowmeter and the oil return pipeline flowmeter which are sequentially connected in series; a split fuel oil input oil tank is led out from the joint between the oil supply pipeline flow meter and the oil return pipeline flow meter through an oil valve, split fuel oil collected by the oil tank is weighed through an electronic scale, and the oil consumption measuring instrument obtains a measurement difference value of the oil supply pipeline flow meter and the oil return pipeline flow meter; and the measurement difference value is compared with weighing data measured by the electronic scale so that precision calibration of the oil consumption measurement equipment is realized. The method is advantaged in that the calibration process is simplified, time and cost are saved, calibration operation efficiency is improved on the premise that overall calibration precision of the oil consumption measuring instrument is guaranteed, and the equipment has advantages of being simple in structure, convenient to operate and high in reliability.equipment.

Description

technical field [0001] The invention relates to a fluid measuring device, in particular to a method for calibrating the accuracy of fuel consumption measuring equipment, and belongs to the technical field of diesel engine manufacturing. Background technique [0002] In the auxiliary engine system of marine diesel engine, the fuel oil supply system maintains the fuel supply of the main engine with stable pressure through the circuit of fuel tank-oil pump-filter-main engine-fuel tank, and there are two main input and main output pipelines on the main engine, so For fuel consumption measurement, a flow meter is arranged on the main fuel input pipe and the main fuel output pipe of the main engine respectively. The currently used fuel consumption measurement method is the application of fuel consumption measurement equipment, which includes a mass flow meter and a fuel consumption meter. The mass flow meter measures the flow values ​​at the fuel inlet of the main engine and the f...
