How to select boiler pump?
The make-up water pump is an important component in the boiler supporting system, and the boiler feed water and boiler hot water circulation are inseparable from it. The choice of a suitable make-up pump should meet the following four points:
1. The flow rate of the make-up pump should be determined according to the normal water supply volume of the hot water system and the amount of water replenishment, which should be 4~5 times of the normal water supply.
2. The lift of the make-up pump should not be less than the pressure of the replenishment point plus the richness of 30~50kpa.
3. The number of replenishing pumps should not be less than two, and should be used for one.
4. The feed water pump should be equipped with frequency conversion speed regulation measures.
How to convert between the three expressions of hot water boiler output?
There are three common expressions for the output of hot water boilers, namely Kcal/h, t/h, and MW. So what do they mean, and what is the conversion relationship between them?
��Large card/hour�� is the expression in the metric unit, which represents the amount of heat that the hot water boiler supplies per hour.
��Tonne�� or ��steamed ton�� is a popular term for borrowing a steam boiler. It means that the heat supplied by the hot water boiler every hour is equivalent to the absorption of a certain mass (usually expressed in tons) of water from 20 �� C and full vaporization into steam. The heat.
��MW (MW)�� is the unit of power in the International System of Units, and the basic unit is W (1MW=1000000W). This expression should be used in official documents.
Conversion relationship of three expressions: 600,000 kcal / hour �� 1 steam ton / hour �� 0.7MW
