Water heater overtemperature protection durability test system

Abstract

The invention discloses a water heater overtemperature protection durability test system. The system comprises a test host and a control cabinet; test host includes bottom of the rack, rack-mounted storage tank, the middle rack mounted on top of the reservoir tank a sink, fast thermal taps set up through the sample holder above the sink, fast water heater through the sample holder to the rack, water storage tanks, sinks, taps and quick fast hot water heater through the water supply systems connection; control cabinet includes console and its internal control circuitry; console includes a display, industrial computer mainframe, buttons, keyboard, PLC control module and the input and output modules. The invention can simulate water heaters that may occur during the actual use of the over-temperature overpressure operation, and can be continued durability testing water heaters standards required to improve efficiency, increase accuracy and consistency tests sex.

Description

technical field [0001] The present invention relates to the testing of fast heating water heaters, in particular to a testing system for testing the reliability and durability of overtemperature protection of fast heating water heaters. Background technique [0002] The national standard GB4706.11 (corresponding to IEC60335-2-35) stipulates in the structural section of the special requirements for the safety of fast-heating water heaters for household and similar electrical appliances that the relevant fast-heating water heaters should be installed to prevent the water temperature at the water outlet that meets the requirements. Excessive protection devices (thermal circuit breakers or pressure switches), and in the chapter on components, specific testing requirements are put forward for whether the above protection devices can meet the requirements stipulated in the standard. Article 24.102 stipulates that this kind of protective device shall withstand 50,000 cycles of temp...

Problems solved by technology

At present, there are only alternative methods such as high and low temperature alternating boxes in China to realize the detection of this project. There is no mature detection system with water collection temperature and water pressure control that can conduct temperature change cycle durability tests on the protection devices of instant water heater products. For For testing agencies and product manufacturers, there is a lack of convenient and effective facilities to implement testing in accordance with the requirements specified in relevant product standards
