In the industrial production of hot water supply. Most of them has long been supplied by industrial boilers, hot water boilers are the traditional coal fired boilers. with the national energy-saving and environmental protection have become increasingly demanding, coal-fired hot water boilers no longer meet the needs of the times, and gas hot water boiler meeting the development needs has become a trend of the future.

In the industrial production of hot water supply. Most of them has long been supplied by industrial
boilers, hot water boilers are the traditional coal fired boilers. with the national energy-saving and
environmental protection have become increasingly demanding, coal-fired hot water boilers no
longer meet the needs of the times, and gas hot water boiler meeting the development needs has
become a trend of the future.
In the process of running a gas hot water boiler, in order to enable operators to control the boiler
drum water level change, you need to install gas hot water boiler water table. However, the hot
water boiler may appear following failures:
1. In the gas hot water boiler water table, there is debris inside the controller, if it is not cleaned for
a long time, the dirt will influence the water level fluctuations and then no water, no alarm, or
there mercury switches or magnetic switches insensitive cause malfunction, should be carefully
adjusted or replaced.
2. repair inside the controller to adjust the ball without pressure to perform during the shutdown,
and pay attention to the polarity of the magnet inside the small, can not hold against (a positioning
groove). Otherwise, the water level can not be adjusted. The electrode sensors are generally due to
controller leak, there is a conductive material on the electrode insulator insulation resistance drop
caused malfunction, once discovered, to promptly arrange shutdown maintenance to ensure safe
operation.
3, gas hot water boiler water table sinking or sliding float part hairy mouth so that does not rise
with the water level fluctuates, causing automatic water when the water level is still kept at the
ceiling is not high water pump or manual alarm.
ZG gas hot water boiler furnace combustion chamber with full bellows structure, both to
strengthen the flue gas disturbance, but also increases the radiation heat transfer area; both
increased furnace stiffness, swelling and effective stress weakens the furnace of ; only enhance the
heat transfer effect, and also promotes fuel combustion in the furnace.
