Publish Time: 2024-06-20
Hydrogen Ejector realizes hydrogen injection by controlling the driving voltage. Its working process can be roughly divided into three stages: current boost stage, peak current oscillation stage and current maintenance stage. In each stage, the opening and closing and alternating changes of the driving voltage are precisely controlled according to the preset parameters.
1. Control method of injection accuracy
Current boost stage: In this stage, the driving voltage provided by the power supply device is controlled to make the Hydrogen Ejector reach the required initial current. When the duration corresponding to the current boost stage reaches the preset value, the driving voltage is controlled to be turned off.
Peak current oscillation stage: According to the preset peak low duration and peak high duration, the driving voltage is controlled to be alternately opened and closed to stabilize the current and reach the peak value. The control of this stage is crucial to the accuracy of injection.
Current maintenance stage: In the current maintenance stage, the driving voltage will turn off the preset switching duration, and control the driving voltage to alternately open and close according to the duration of the current maintenance stage, the preset low maintenance duration and the preset high maintenance duration. This process helps to maintain stable hydrogen injection.
2. Accuracy of injection precision
The injection precision of Hydrogen Ejector is affected by many factors, including the stability of driving voltage, the accuracy of control algorithm, changes in hydrogen pressure and temperature, etc. Therefore, to achieve high-precision injection, advanced control technology and precise measuring equipment are required.
Regarding the specific accuracy of injection precision, it may vary due to different Hydrogen Ejectors and application scenarios. However, by adopting precise control algorithms and advanced measurement technologies, very high injection precision can be achieved. For example, some advanced Hydrogen Ejectors can achieve millisecond-level response time, and the error of injection amount can be controlled within a very small range.
The injection precision control of Hydrogen Ejector is a complex and critical technical issue. High-precision hydrogen injection can be achieved by precisely controlling the opening and closing and alternating changes of the driving voltage, and by adopting advanced control algorithms and measurement technologies. However, the specific injection precision will be affected by many factors, so it needs to be debugged and optimized according to the specific situation in actual application.
