Technical Field

Background

The Quad600/800 combustion controller is suitable for a direct ignition controller with 350KW, conforms to the European standard EN746-2 and is expensive. It has an LED flame signal indication and advanced self-diagnostic system. The main burner receives the start and control of the remote input signal after the pilot ignition detection for 3 seconds. The air valve can be directly controlled remotely once the device is opened, and the dry contact is used for monitoring of the air valve, the gas valve and the remote burner. The combustion controller can configure time and period, thus can meet different types of gas environment and gas requirements and meet all relevant regulations.

A part of heat treatment lines adopt Quad600/800 type combustion controllers to control gas combustion in the furnace, although the normal service life of a single combustion controller can reach three years, the number of the Quad600/800 combustion controllers used on site on line reaches 360. Therefore, the number of damages accumulated per month is still high. On one hand, related workers often cannot judge the quality of the combustion controller, and frequently replace the good device by mistake; on the other hand, in order to reduce cost and improve efficiency, the damaged combustion controller exceeding the quality guarantee period is disassembled and repaired, but the function of the repaired part cannot be guaranteed to be consistent with the original state after the components are replaced.

At present, no relevant detection instrument exists in the industry, so that an offline test platform of the Quad600/800 combustion controller needs to be built, and various signals given by actual production on a simulation field are used for offline testing of a replaced part and a repairing part, so that the stability and the reliability of the replaced part and the repairing part are ensured, and relevant workers can use the device at ease.

As shown in fig. 1, the process flow for simulating actual production on site is as follows: firstly, after power-on, complete self-checking is carried out once, flame simulation test is completed in pre-ignition or standby time, and the test is carried out to determine whether an ignition fault signal exists or not and whether a purging link has a problem or not. In the pre-ignition stage, the ignition device is detected and the gas valve is activated. After a programmable safety time, when a flame signal is detected, the terminal connection of the combustion controller is closed, indicating that the burner is open. If the flame signal is not detected, the system enters a blocking state, manual reset is needed, and the whole process is repeated. After the time for the entire combustion controller operation is completed, the auto-close may be activated.

As shown in fig. 2, the implementation of the test platform in this embodiment: an insulating wooden board is used as a base 12 of each component, a support is installed on the wooden board base 12, then each test module (component) of an analog signal is installed on the support and is linked through a signal wire, then each signal wire of each test module is combed, each signal wire is connected into a self-made wiring terminal row according to the working principle of a combustion controller, the wiring terminal row is ensured to correspond to the terminal of the combustion controller one by one, the wiring terminal row is ensured to be just inserted into the combustion controller, and signal connection is realized.
