Product Description

Ning'an gas box surge regulator provides reference for reducing pressure.
1 the gas supply system is adjusted according to the requirement of the natural gas pressure provided by the manufacturer, the maximum value is less than 0.07MPa, and the gas supply pressure of the pipe network is 0.25MPa. Therefore, a pressure regulating valve must be added to adjust the pressure to the specified range. After entering the debugging stage, by adjusting the pressure regulating valve, the pressure can be adjusted to the appropriate range, but a little after a while, the pressure of the valve is slowly rising, and finally balance with the pressure of the pipe network to reach 0.25MPa, and it can not play the role of pressure regulating.
How to solve the trouble of the gas pressure regulating valve used in Run Feng
(1) fault judgment. The reasons why the regulator can not be stabilized is improper adjustment, improper installation method, self defect of the pressure regulating valve, and foreign matter stuck to the spool. According to the cause of the investigation and communication with the manufacturer, the installation and debugging factors were excluded, so the professional personnel dismantled the body, checked and cleaned the foreign objects, and no obvious problems were found. At this time, the fault could be judged to be the result of the quality defects of the newly installed pressure regulating valve.
(2) problem solving. Because the new 1 order pressure regulating valve has a longer cycle, it is decided to dismantle and replace 1 units temporarily. Through comprehensive evaluation, we found 1 old pressure regulating valves with an inlet and outlet diameter of DN50mm (the original pressure regulator caliber is DN65mm). After analyzing the main parameters of new parts and old parts, it is considered that they can be replaced. After installation and commissioning, it meets the requirements of temporary use and smoothly enters the next debugging process.

Debugging of 2 instrument electric control system
The ignition problem of 2.1 burners is selected as the German OUKE EKEVO7.4500G / E, the type of fuel is natural gas, which is a blast burner, the first air coefficient is 0, the structure is compact, and the heat load regulation range is large. Start the boiler, normally enter the starting program, before blowing a little fire a little fire a little fire a flame monitoring, in which the blowing, fire, small fire action is normal, but a few seconds after the small fire is extinguished, repeated many times, so many times.

(1) problem finding. Check the ignition system, including the igniter, the ignition line, the ignition electrode, not found the abnormal, and repeatedly adjust the flame disc and the ignition electrode gap, and the fault is still the same. It is doubted that the air-fuel ratio is not properly adjusted, so the ratio of the valve to the opening of the gas butterfly valve is repeatedly tested by manual method, and the large, medium and small opening tests are repeated many times. Yes, but the problem is still unsolved.
(2) problem solving. The cause of the analysis may not be the problem of the ignition system. If the flame monitoring system has problems, the control system can not detect the A-level current produced by the flame detection electrode, and the system identifies that the flame is not ignited to carry out the extinguishing protection. Check the flame detection electrode and terminal, find that the terminal wire is wrong when it is out of factory, re wiring, the problem is solved.
