First, the principle of boiler feed water pump
In the thermal power plant, the main role of the boiler feed pump is to draw water from the water source, after a certain process of treatment, and then transported to the turbine boiler system, to provide enough water for steam generation. In simple terms, the role of the boiler feed pump is to provide water for electricity generation.
In the working process of the boiler feed pump, water needs to enter the boiler feed pump through the inlet pipe, and then through the impeller of the pump by centrifugal force, compressed and carried to be transported to the boiler system. At this time, in order to ensure the normal operation of the feed pump, it is necessary to ensure that the air is completely excluded to prevent cavitation and other phenomena, therefore, the feed pump usually needs to be equipped with a gas removal device.
Second, the importance of the boiler feed pump in the power plant
In a power plant, the feed pump is one of the essential equipment, which can ensure that there is always enough water in the boiler system, and has a very important impact on the normal operation of the boiler and the efficiency of power generation. Specifically, the importance of the feed pump is reflected in the following aspects:
1. Ensure the normal operation of the boiler system. The water supply provided by the water pump can meet the water needed by the boiler, so as to ensure the normal operation of the boiler.
2. Improve power generation efficiency. The water supplied to the pump can reduce the temperature of the boiler water, thereby reducing the loss and depreciation of the steam turbine and improving the power generation efficiency of the power plant.
3. Ensure the continuity of power production. If there is not enough water in the boiler system, the entire plant will be shut down. The addition of the feed pump can ensure sufficient water supply, so as to ensure the continuity and uninterrupted power production.
In summary, the role of the boiler feed pump in the power plant is very critical. In order to ensure its normal operation, the power plant also needs to be regularly maintained and maintained, so as to extend the service life of the equipment and reduce the occurrence of failures.
