Precise Control of Electric Proportional Valve in Fuel Cell Test Bench
Precise Control of Electric Proportional Valve in Fuel Cell Test Bench
The automobile industry is the main industry in the world's industrial countries. With the gradual increase in the number of cars in the world, the problems of energy shortage and environmental pollution have become more and more prominent. Hydrogen energy and fuel cell technology have the advantages of good environmental performance, high conversion efficiency, short filling time and long cruising range, and have become a major strategic direction for the world's energy and power transformation.
With the increasing demand for fuel cell vehicles, the demand for high stability of fuel cell systems is becoming more and more intense. The fuel cell test bench has become a powerful guarantee for testing the performance and quality of the fuel cell through real-time precision detection and abnormal alarm of the fuel cell air tightness, starting performance, steady-state working condition, aging performance, insulation withstand voltage performance, etc. in accordance with national standards.
Fuel cell test bench
electric proportional valveAs an important component in the gas pressure control in the fuel cell test bench, the air-fuel ratio and output power in the fuel cell are guaranteed by controlling the pressure and flow of hydrogen and compressed air entering the fuel cell.such as electrical proportional valveDue to poor production consistency,The aging of the internal structure and other factors lead to changes in the dynamic response and control accuracy of the electronically controlled proportional valve,will beleading to its control into the fuel cellGas pressure andDecreased flow accuracy,ThenImpactFuel cell test benchThe normal useand test accuracy.
Fuel cell test bench hydrogen and compressed air unit composition
United StatesPROPORTION-AIRUltra-high-resolution, closed-loop voltage-controlled proportional valve, built-in2a solenoid valve,1 pressure sensor and electronic control circuit.The variable pipe diameter allows the proportional valve to precisely control the output pressure under low flow and pressure conditions, and eliminates the pressure jitter of traditional solenoid valve switching. The improved electronic circuit adds a more precise solenoid valve at the air inlet, which eliminates electronic steps, noise, and wear between the valve and the device. At the same time, it also overcomes the remaining problems in the traditional technology, such as the influence of external shock and vibration, the ability of no closed loop, the output pressure changes with the input pressure, and no feedback.
In a nutshellPROPORTION-AIRProportional valveIt provides the most convenient operation function for users, solves the inherent problems in the traditional technology of gas circuit system, and meets the application requirements of fuel cell test bench to the greatest extent.
