1. Which is better for measuring the flow rate of diesel, vortex street or V-cone?
What flowmeter is better for measuring diesel or other oil media? For diesel with low viscosity, we recommend commonly used and cost-effective vortex flowmeters and turbine flowmeters. Zaizha code is suitable for some oils with high viscosity, such as engine oil. So can we use vortex flowmeter and turbine flowmeter? The answer is definitely no. Speaking of which, why does Chai Nian have such advantages when using a vortex flowmeter for diesel? Here, we need to analyze the characteristics of the vortex flowmeter. Only in its features can you find the advantages of the vortex flowmeter and feel why we recommend using it for measuring diesel. The principle of vortex flowmeter is based on the principle of Karman vortex street. In terms of structural construction, it is a vortex generator inside the pipeline. The fluid passes through the vortex generator to generate Karman vortex, and the instantaneous frequency of the fluid is calculated by the sensor. The cost of vortex flowmeter is relatively cheaper than other flowmeters. The vortex flowmeter also has some outstanding characteristics in terms of usage:
1. The volumetric flow rate is not affected by thermal parameters such as temperature, pressure, density, or viscosity of the measured fluid.
2、 No movable parts, simple measuring element structure, reliable performance, long service life
3. High accuracy, repeatability of 0.5%, and low maintenance.
4、 Can measure the flow rate of liquids, gases, or vapors
5. Generally does not require separate calibration
6. Wide measurement range. The range ratio can generally reach 1:10
7. The pressur
2. Why is the air flow meter of a diesel car old and broken?
Detecting engine air flow meter data stream, out of range. High fuel consumption, weak acceleration, and black smoke from the exhaust pipe. Based on the data flow combined with the fault phenomenon, determine the malfunction of the air flow meter. When accelerating, the fuel injection pulse width increases, but the increase in air flow rate is basically negligible, which will result in an inappropriate air-fuel ratio and inevitably weak acceleration. Inspection and Analysis of Resistance Difficulty: After testing with a fault diagnosis instrument, it was found that the data block of the engine air flow meter severely exceeded the standard. The reason for the damage to the air flow meter is often due to the use of inferior air filters or the lack of regular replacement of air filters, which causes dust to stay on the hot wire of the air flow meter for too long, resulting in inaccurate or ineffective changes in its resistance value. In addition, dust can cause the throttle body to be too dirty. Replace the air flow meter, clean the throttle body, and replace the original air filter.
