Seven phenomena, causes, and solutions of noise generated by Ruineng wall mounted furnaces!

Wellant Ruineng Wall Mounted Stove (www.wellant. cn) China's brand operating agency is affiliated to Xi'an Ruineng Thermal Power Technology Co., Ltd. The production base of Ruineng Wall Mounted Stove is located in Shenzhen. Currently, Ruineng's main products include L1P-B household gas heating/domestic hot water dual purpose wall mounted stoves and L1P-H household gas heating and bathing wall mounted stoves, with main components such as water pumps, heat exchangers, safety valves, water tanks, etc. All of its products are selected from European products and technologies, Make the product operate more reliably and have a longer service life. Ruineng wall mounted furnaces explore the market through direct sales from manufacturers, establish a complete set of professional maintenance and after-sales service system, and provide pre, during, and after sales services for products.
The common noise problems of Ruineng wall mounted furnaces include fan noise, heat exchanger noise, combustion noise, water pump noise, and heating system noise. It is not easy to distinguish between noise, especially fan and combustion noise, and it is easier to distinguish when opening the outer cover of the Ruineng wall mounted furnace. During the process of using the Ruineng wall mounted furnace, the self inspection process is very necessary, which can eliminate potential safety hazards for users.
1、 Common noise problems of Ruineng wall mounted furnace
Symptoms:
a) During ignition, there is a roar in the wall hanging furnace of Ruineng;
b) Excessive noise caused by ignition delay;
c) Excessive noise generated during combustion;
d) Excessive noise from boiling water during heating;
e) Excessive water flow noise and water pump noise in the heating system;
f) Machine vibration during operation;
g) The shrill sound of a fan.
Fault cause:
a) Caused by excessive gas consumption during initial ignition;
b) The ignition electrode spacing is too large or too small, resulting in irregular ignition of the ignition electrode; Fault caused by poor pulse igniter itself;
c) The length and elbow of the flue do not meet the requirements; The air tightness of the exhaust pipe is damaged, and the exhaust gas is absorbed, resulting in noise; The gas pressure is too high; The maximum current of the proportional valve is too high;
d) When heating water is heated to a higher temperature in a combustion heat exchanger, water burning noise can occur. This excessive noise is caused by poor water quality, poor welding of the main heat exchanger fins, or blockage in the heat exchanger;
e) There is air in the pipe;
f) Vibration caused by unbalanced fan;
g) Impeller imbalance, too much dust causing dirty blockage;
resolvent:
a) Adjust the gas pressure if the air pressure is too high; If the gas valve is a proportional valve, reduce the proportion; If the gas valve is a segmented valve, adjust the small fire regulator to reduce the flow of small fire gas;
b) Adjust the ignition needle distance or replace the pulser;
c) Improper flue installation and correction of installation; Seal or replace the chimney with tinned paper due to air leakage;
d) Improve water quality or replace heat exchangers;
e) Exhaust the air in the system;
f) Adjust the soft connection point of the fan to balance it;
g) Clean the fan impeller and cavity.
