暖气温度不足因素排查（Heating temperature shortage factor investigation）

暖气温度不足因素排查（Heating temperature shortage factor investigation） I. heat source: (28 factors) 1.1, replenishment factors: 1.1.1, low pressure point: water pump fixed pressure point is low, the system is not tall buildings hot. 1.1.2, water pump failure: water pump problems, no standby pump, the system seriously water deficit. 1.1.3, inverter failure: water pump inverter failure, replenishment is not timely. 1.1.4, expansion tank water shortage: due to water supply, signal failure and other reasons, resulting in expansion tank water deficit. 1.1.5, replenishment box small: the system water deficit serious, fill tank volume can not meet the need for water replenishment. 1.1.6, water supply: accidents caused, and other water shortage cities may also occur this situation, resulting in water can not afford. 1.2, cycle factors: 1.2.1, circulation pump failure: the circulation pump has the problem, does not have the spare pump, the system does not cycle. 1.2.2, intermittent cycle: to save electricity, part of the heating management unit often stop the pump, the system is unstable. 1.2.3, circulating pump flow is small: cause users large area is not hot. 1.2.4, circulating pump head low: cause end user is not hot. 1.3 boiler factors: 1.3.1, boiler capacity is small: the existing boiler heating capacity can not meet the actual needs of users. 1.3.2, the low efficiency of boiler: boiler capacity seems to meet the needs, but because of inadequate fuel combustion and exhaust temperature of the boiler, boiler water, boiler fouling serious surface heat dissipation caused by boiler efficiency is low, resulting in the stage of heating is not cold. 1.3.3, stop the furnace: the boiler is out of order and no spare furnace is under repair. 1.3.4, poor fuel: poor quality fuel, low calorific value, and even difficult to start or stall frequently. 1.3.5, fuel consumption is small: some heating management units only focus on their own economic interests, at the expense of the interests of use
