electric heating condensing water tube hot water boiler
Common Problem and Solution gas electric heating condensing water tube hot water boiler 1, the power supply is turned on, by cause of failure is not running after starting the motor are: (1) locking pressure less; (2) solenoid valves lax, joints leak, check the lock; (3) thermal relay opens; (4) condition loop at least one is not satisfied (water level, pressure, temperature, and the programmable controller is powered starter) Remedy: (1) adjusting the air pressure to a predetermined value; (2) cleaning or repair of the solenoid valve conduit linker; (3) press the reset element checks whether the motor current and damage; (4) check the water level, pressure, temperature gauge 2 if, after the normal purging before the start, but misfire malfunction Cause: (1) the amount of electric anger ; (2) the solenoid valve does not work (the main valve, an ignition valve); (3) a solenoid valve burned; (4) pressure instability; (5) the air volume is too large Remedy: (1) inspection and repair line; (2 ) renewal; (3) to adjust the pressure to a predetermined value; (4) decreases with the wind, to reduce the throttle opening 3, misfire, normal air pressure, there is no ignition power failure causes: (1) the ignition transformer burnout ; (2) high-voltage damage or loss; (3) the gap is too large or too small, the relative size of the firing rod position; (4) and electrode breakage or Short circuit; (5) inappropriate pitch, Remedy: (1) renewal; (2) or re-install new ones; (3) 4 readjust after the 5S flame lit, fault cause: (1) is less than atmospheric pressure, too much pressure drop, gas flow is small; (2) air flow rate is too small, incomplete combustion, darker smoke color; (3) the air volume is too large, the gas appears white Remedy: (1) re-adjusting the air, the filter cleaning ; (2) 5 readjusted, fault cause white smoke: (1) air flow rate is too small; (2) too much humidity; (3) a lower exhaust gas temperature, Remedy: (1) transfer of small damper; (2 ) appropriate to reduce the air volume and improve the inlet air temperature; (3) take measures to increase the exhaust gas temperature 6, chimney dripping failure reasons: (1) ambient temperature is low; more (2) a small fire combustion process; (3) gas hydrogen-peroxide amount generated water; (4) long chimney Remedy: (1) reducing the amount of air distribution; (2) reducing the height of the chimney; (3) increase the oven temperature; (4) than the exhaust gas temperature low, stopping state under the control of the damper, the damper position switch signal is not fed back to the program signal, throttle check whether the wiring is loose or switch failure.
To meet the domestic water electric heating condensing water tube hot water boiler manufacturers also 1, electric boilers: electric boiler today is the most energy saving boiler, the government also tried to promote the product, the product is easy to operate during use, easy to control, it is the first choice for home heating, but boiler gas boiler use is still relatively expensive. 2, gas boilers: gas boilers moment also present a good product, gas boilers and boiler floor is divided into two kinds of boilers to meet ordinary family life mainly boiler heating, convenient and space-saving, wall-hung boilers not only we can provide low temperature hot water floor heating systems, but also to meet domestic water. Home heating or gas-fired boiler or electric boiler selection, but easy to operate control electric boiler, but also get a lot of families. Gas boilers and electric boilers are cleaning boilers, meet the energy requirements of environmental protection. National Day is coming soon, the water boiler manufacturers also can be said now is the best season maintenance of electric boilers. We are in the heating season each year around November, usually through the use of electric boilers for heating season will be a shutdown, a pre-heating of the following year, in order to ensure safe, we need maintenance. Now is the repair, change. 3, gas boilers: gas boilers although it is a mass product, but also much loved family, the Water Cube Hotel 2 tons of gas boilers, gas boilers but more pollutants generated in the course of their work, to pollute our environment, and such gas-fired boiler has not been approved for use in the relevant sectors.
Gas-fired electric heating condensing water tube hot water boilers are maintained twice a month on a regular basis. Inspection of fuel supply lines: 1. Light oil filter cleaning; 2. Air tightness inspection of ignition gas pipe road; 3. Check to see if the line is clear. b. Inspection of instruments: 1. Water level gauge flushing; 2. Pressure gauge bend flushing; safety valve test. c. Inspection burner: flame detector (electric eye) cleaning light surface; 2. Check whether the working pressure of oil pump is normal; 3. Check that the combustion flame is normal; 4. Check if the burner sound is abnormal when burning; 5. Clean cup disk; 6. Wash some water bars. d. Inspection of intake systems: 1. Cleaning water filtration 2. Whether the pump reaches the rated head and flow rate; 3. Check valve is working properly. e. Daily fuel tank drainage and cleaning debris. Water quality test, furnace water test. f. Check combustion consumption is normal. Maintenance projects every three months in addition to the above inspection items: A. Electrical parts: 1. Whether the line has loose aging, failure; 2. Checking the reliability and overload of electrical components; 3. B. When the soft water tank is not in use, open the low valve to remove the sludge. Testing boiler re-point interlock device: 1. Low water position; 2. Overpressure; 3. Turn off 4. Exhaust temperature Superelevation; etc. Smoke detection: including smoke composition analysis and tail smoke temperature detection, check whether the combustion is working or not. e. Clean boiler body and burner exterior. A. The main body part completely cleans the smoke pipe, water pipe, front and rear smoke box, furnace part and burn-up chamber and smoke pipe ash collection. 1. Fully open the cover to check the sealing integrity of the manhole, etc., and replace the defective gasket in time. 2. Complete inspection of integral instruments, valves, including pressure gauges, pressure controllers and electrode level controllers, and safety valve tuning. b. Burner section: comprehensive Clean burner rotor disc, ignition device, filter, oil pump, motor and impeller system, lube the valve connecting rod. Re-test combustion conditions. c. Control part maintenance and inspection of electrical components, control lines, clean control box ash collection, each control point for inspection. d. Repair water treatment equipment, check water quality, clean soft water tank, check operation and head of feed water pump, clean check valve core, etc.
People's Republic of Bangladesh is the world's largest exporter of jute, a long time for the world transport a large paper stock. Is also an important market, "along the way" important strategic fulcrum of China's industrial and manufacturing. Fang fast Group as an international brand electric heating condensing water tube hot water boiler, April 10, the warm reception from distant friends -?
