Embodiment Construction

[0038] A comprehensive performance testing method for a "mobile integrated" gas cooker is carried out according to the following steps:

[0039] (1) Carry out an air tightness test.

[0040] Place or install the gas cooker on the test bench, and use a special gas leak detector or the air or nitrogen pipeline that comes with the system to check the gas tightness of the gas system and combustion system of the gas cooker.

[0041] (2) Adjustment of combustion conditions.

[0042] According to the reference gas source category, rated air supply pressure and rated heat load parameters marked on the nameplate of the gas cooker, set the reference gas, burn and ignite; adjust the best combustion condition of the cooker by adjusting the air damper at the bottom of the cooker, and maintain the The state remains unchanged, and all test processes are completed.

[0043] (3) Carry out thermal load test.

[0044] Using the rated pressure and reference gas marked on the cooker, within 15-...

Abstract

The invention relates to a mobile integrated gas cooker comprehensive performance experiment tester. The tester comprises a raw material gas supply device, a branch pipeline gas flow metering device, a pipeline valve, a mixed gas female pipe, a pressure display instrument, an electric switch valve, a gas filter, a safety relief valve, a gas flow meter, a remote control gas pressure regulator and a front combustor valve, wherein an outlet of the front combustor valve is connected with a test gas tool, the test gas tool is equipped with a test pan, a pan cover of the test pan is equipped with a water temperature measurement thermocouple or a mercury thermometer and a stirrer, and temperature signals of the water temperature measurement thermocouple are transmitted to a host computer through a data / signal transmission wire. The tester is a full-flow efficacy and combustion characteristic detection system from various gas distribution test gas source ends to a test gas cooker tail end, and realizes discrete test and examination on air tightness, thermal load, combustion condition, thermal efficiency, flue gas discharge index and temperature rising of the gas cooker so as to realize assessment and quantification of thermo-technical and safety performance of the gas cooker.

Description

Technical field: [0001] The invention belongs to a testing and experimental method for measuring the comprehensive performance of a gas cooker, in particular to a technical method and an experimental system for comprehensively measuring and evaluating the thermal performance and safety performance of a gas cooker. Background technique: [0002] Gas cooker performance tests mainly include air tightness, thermal load, combustion conditions, temperature rise, thermal shock resistance, gravity shock resistance, safety devices, performance, electrical performance, durability and other items. For household gas cookers, there are four key project indicators related to gas quality and combustion: ① energy efficiency indicators, such as heat load and thermal efficiency; Such as CO and NOx concentration; ④ safety, such as air tightness, safety devices, etc. This is the core item we will test in production R&D, type testing and other testing. [0003] For the above key test items, fo...
