Production adjustment and detection equipment for gas water heater

Abstract

The invention discloses production adjustment and detection equipment for a gas water heater. The production adjustment and detection equipment is characterized by comprising a main control chip, a current sensor, a pressure sensor and an operation display, wherein the main control chip communicates with a main controller of the gas water heater, and the current sensor, the pressure sensor and the operation display are connected with the main control chip; the current sensor is used for detecting the current output by a main board of the gas water heater; and the pressure sensor is used for detecting secondary pressure of the gas water heater. According to the production adjustment and detection equipment, whether the secondary pressure value of fuel gas fits the working load of the gas water heater is judged through detection, a related instruction to the main controller of the gas water heater, and the main controller adjusts a gas proportional valve according to the set code so as to realize automatic setting. The current of the gas proportional valve of the water heater and the output current of the main board are detected and contrasted with the secondary pressure of the fuel gas, whether the output of the main controller of the water heater has deviation or not can be judged, whether the gas proportional valve has deviation or not can be judged, whether a square tube is blocked or not can be judged, and therefore the online intelligent detection can be realized.

Description

technical field [0001] The invention relates to the technical field of detection of gas water heaters, in particular to a detection device for production regulation of gas water heaters. Background technique [0002] The parameters of existing gas water heaters are based on laboratory test data or calculated to obtain the maximum gas consumption and minimum gas consumption of gas water heaters. In the production of existing water heaters, it is necessary to manually adjust and calibrate the parameter code according to the pressure of the test equipment. When the manual adjustment error is too large, it will have a great impact on the comfort and the work of the whole machine, and noise, vibration, and temperature overshoot often occur. Moreover, manual adjustment is prone to errors and omissions during mass production, and the labor cost is relatively high. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present inven...

Problems solved by technology

In the production of existing water heaters, it is necessary to manually adjust and calibrate the parameter code according to the pressure of the test equipment. When the manual adjustment error is too large, it will have a great impact on the comfort and the work of the whole machine, and often appear noise, vibration, and temperature overshoot.

In addition, manual adjustment is prone to errors and omissions during mass production, and the labor cost is relatively high
