Device and method for automatically testing bubble point pressure of diaphragm

Abstract

The invention discloses a device for automatically testing diaphragm bubble point pressure. The device comprises a gas pipeline; the pressure control valve is arranged at the front end of the gas pipeline; a pressure sensor disposed downstream of the pressure control valve; the first electromagnetic valve is connected with the pressure sensor in parallel; the second electromagnetic valve is connected with the pressure sensor in series, and the second electromagnetic valve is arranged at the downstream of the pressure sensor; the membrane fixer is arranged at the downstream of the first electromagnetic valve in series; the liquid level sensor is connected with the membrane fixer; and the pressure control valve, the pressure sensor, the liquid level sensor, the first electromagnetic valve and the second electromagnetic valve are all electrically connected with the control cabinet. The pressure control valve, the electromagnetic valve, the liquid level sensor, the pressure sensor and the control cabinet are used in cooperation, automatic measurement of the diaphragm bubble point pressure is achieved, manual monitoring and recording are not needed in the testing process, and the testing efficiency of the diaphragm bubble point pressure is improved.

Description

technical field [0001] The invention relates to the technical field of electrolytic hydrogen production, in particular to a device and method for automatically testing the bubble point pressure of a diaphragm. Background technique [0002] With the rapid development of the global economy, the shortage of fossil energy and environmental pollution have become two important issues in the 21st century, and the development of efficient, renewable and clean energy is imminent. Hydrogen energy has the advantages of wide sources, clean and carbon-free, flexible and efficient, and rich application scenarios. It is considered to be an important carrier to support energy transformation and build a modern energy system, and it is one of the major strategic directions of my country's energy transformation. Hydrogen production by electrolysis of water is a green and environmentally friendly method for producing hydrogen with a relatively simple and flexible production process. Hydrogen p...
