Problems solved by technology

The traditional volumetric flowmeter cannot eliminate this error; moreover, the calibration of the fuel consumption meter installed on the vehicle is also a problem, which needs to be disassembled and calibrated on the test bench, which is troublesome
At present, there is no flowmeter that allows online calibration easily without disassembly

Embodiment Construction

[0021] Such as figure 1 , Figure 4 , Figure 5 , Figure 7 , the present invention adopts two channels, one oil inlet channel 1 and the other oil return channel 2; orifice throttling devices (sleeves with orifice plates 1-4, 2-4,) are respectively provided in these two channels and pressure pilot holes 1-6-1, 1-6-2 and 2-6-1, 2-6-2 (see figure 2 , image 3 ); Two sensors 1-6-3 and 2-6-3 capable of measuring positive and negative differential pressure are installed on the pressure guide hole, so that each pipe can measure both forward flow and backflow; oil inlet channel 1 The difference with the forward flow of oil return channel 2 is the fuel consumption. In addition, two temperature sensors 1-3 and 2-3 are used to measure the oil temperature of the two channels respectively, so that the actual density of the oil inlet channel 1 and the oil return channel 2 can be known, and the respective mass flow rates can be measured, so that the The flow rate is used to calcu...

Abstract

An oil consumption flowmeter of a diesel engine belongs to a flow meter, which is provided with an oil inlet channel and an oil return channel, wherein the two oil line channels are respectively provided with an inlet pipe and an outlet pipe which are arranged on the same plane; an oil inlet channel plane is arranged above an oil return channel plane; and a channel between the inlet pipe and the outlet pipe is provided with a connector capable of being installed with a standard quantifier. The flowmeter is characterized in that the two oil line channels are respectively provided with a pore plate throttling device and a pressure conductive port, and the pressure conductive port is installed with a differential pressure transducer; and the two oil line channels are respectively provided with a temperature sensor and a public valve, and the inlet and outlet of the oil inlet channel are provided with oil gas separation channels. The invention has high measurement precision, is free of influence of return oil and bubbles, can check in an on-line mode and is capable of being connected with a computer.

Description

technical field [0001] The invention relates to a fuel consumption flow meter for a diesel engine, in particular to a vehicle mass flow fuel consumption meter which can be used with the vehicle. Background technique [0002] Most of the existing fuel consumption flowmeters for diesel locomotives are positive displacement flowmeters, such as piston flowmeters and oval gear flowmeters. In actual use, this kind of fuel consumption flowmeter will cause errors due to factors such as environmental temperature changes and oil temperature changes that seriously affect the density; and sometimes there will be a small amount of oil returned from the oil inlet pipe, and the positive displacement flowmeter cannot measure normally at this time. . [0003] In another standard mass fuel consumption tester used on a vehicle performance test bench, the weighing method is used as a mass fuel consumption measurement. Although it is very successful, it is huge in size and requires ...
