TLDR
In this paper, a test method for ignition performance of a gas heater is presented. But the test method is based on a test system for the gas heater and does not consider the air pressure closing time.Abstract:
The invention discloses a test method for ignition performance of a gas heater. The method comprises the following steps: controlling opening of an electric water stop valve and starting timing when water flow flows in, after ignition, obtaining air pressure detection closing time T1 when an air pressure closing signal is detected; after a flame normal combustion signal of the heater is kept at afirst time threshold value, obtaining ignition success time T2, and determining the ignition performance of the heater according to the air pressure detection closing time T1 and the ignition successtime T2. The invention further discloses a test system for ignition performance of the gas heater and the gas heater. According to the test method and system for ignition performance of the gas heater, and the gas heater in the invention, the important ignition performance parameters such as the time from a water getting point of a user to successful closing of the air pressure, successful ignition time and the like can be full-automatically tested, and the accuracy of the test result is high.read more
