In the process of using the fire pump, the self-check mode can not only prevent the corrosion of the fire pump stuck, but also alarm the motor, short circuit, overpressure, overheating, etc. The constant speed self-check mode and low speed self-check mode have played a certain role in the maintenance of the fire pump.floating fire pump
1, from the point of view of maintenance management, they can be used in the fire water supply system. Relatively speaking, constant speed self-test can reflect the actual operating conditions of the fire pump. From the point of view of the fire pump failure, the failure caused by the fire pump for a long time is mainly the occlusion of the shaft of the pump unit. The motor start incomplete condition problem is less, so overemphasis on the fire pump complete condition operation, its significance is not very big.floating fire pump
2. Although the low-speed self-test method is not comprehensive to the operation detection condition of the fire pump, it has no special requirements for the design of the fire pump pipeline, and basically can be applied to the technical requirements of the fire pump self-test. It is more suitable for fire pump directly from the municipal pipe network water absorption.floating fire pump
3, constant speed self-test method is suitable for the fire pump from the fire pool water, the design should be reasonable consideration of the layout of the pipeline. There are some problems in operation, which can cause overpressure quickly, so it is not suitable for application in engineering. Constant speed and low speed self-test have their own characteristics.
In the process of use, it is also necessary to conduct regular manual inspection and maintenance of the fire pump, because the self-inspection of the fire pump cannot completely replace the manual maintenance and management of the fire pump.
