hydrogen

The nitrogen and hydrogen proportioning equipment mainly adopts the control of the flow rate of hydrogenation or nitrogen addition to achieve the purpose of mixing hydrogen and nitrogen in a certain proportion. In general, it is to control the flow of gas with less content. A nitrogen-hydrogen proportioning equipment mainly consists of nitrogen flowmeter, hydrogen flowmeter, hydrogen analyzer, PID controller, flow control valve, pressure gauge, mixing tank, chassis etc. composition. The hydrogen analyzer measures the hydrogen content in the mixing tank. The hydrogen analyzer converts the measured content into a 4-20mA signal and transmits it to the PID controller. The PID controller converts this signal into a mechanical signal to the flow control valve. Send out an action command to direct the opening of the flow control valve. The opening of the flow control valve determines the hydrogen content in the mixing tank. During continuous adjustment, the purpose of mixing hydrogen and nitrogen in a certain proportion is achieved. (1) There are sound and light alarm equipments for the upper and lower limits of hydrogen excess. (2) When the online hydrogen content exceeds the set index, the hydrogenation pipeline will be automatically cut off. (3) There is a manual hydrogenation pipeline, which is used in special cases to ensure the operation of the whole equipment. (4) The sound and light alarm equipment with ultra-high pressure and low pressure is designed
