Commissioning of gas supply pipeline
After the burner is installed, it is necessary to connect it to the air supply pipe network. The diameter of the gas supply pipe should meet the requirements of air supply, and the pressure loss should not exceed 5mbar. For the burner, when the diameter of the gas supply pipe is 1.5 or 40mm, the connection of the gas supply pipe of the burner should leave enough space to ensure the opening of the burner, so as to facilitate future maintenance work. Install the following components in sequence: 1. Ball valve; 2. Filter; (3A. Pressure regulating valve); 4. Double solenoid valve. If the gas pressure is higher than 500mbar, it is necessary to install a voltage regulator at the front of the pressure regulator valve to ensure that the gas pressure at the front of the pressure regulator valve is between 300-500mbar.
The following points should be noted when installing the components:
a.In order to avoid the gas pressure dropping too much when the burner is working, the distance between the pressure stabilizer valve and the double solenoid valve should not be more than 1.5 meters. The double solenoid valve is as close to the burner as possible, and the diameter of the pipe should not be less than 40mm.
b.All parts must be installed horizontally. If the double solenoid valve and the pressure stabilizer valve are installed vertically, the resistance of these parts will be increased.
c.Air tightness should be checked after all pipes are connected.
the inspection work before the start
a.Check whether the cables and wires are properly connected; Check the supply voltage, 380-400VAC, check all motor steering; Check whether each instrument works normally.
b.Disconnect the servo motor and check whether the damper mechanism and gas butterfly valve are flexible.
c.Check whether the photoelectric eye works normally. Check air tightness of heat conducting oil pipeline.
d.Start the heat conduction oil circulating pump, add the heat conduction oil of appropriate specifications as required until the oil shortage indicator is extinguished, check whether there is leakage in the heat conduction oil pipeline, and tighten it if necessary.
