In the use of the Fire Pump, the self-check mode can not only prevent the corrosion and jam of the Fire Control Pump, but also alarm the motor, short circuit, overvoltage, overheating, etc. Both the normal speed self-check mode and the low speed self-check mode play a certain role in the maintenance of the Fire Control Pump.
1, from the point of view of maintenance management, they can be used in the fire water supply system. Relatively speaking, the constant speed self-test can reflect the actual operating conditions of the fire pump. From the point of view of the cause of fire pump failure, the failure caused by the long-term use of fire pump is mainly the occlusal problem of the shaft of the pump unit. There are few problems in the condition of incomplete motor start, so it is not very significant to overemphasize the complete operation of fire pump.
2. Although the low-speed self-test method is not comprehensive for the operation and testing conditions of Fire Pump, it has no special requirements for the design of Fire Control Pump pipeline, and can basically be applied to the technical requirements of Fire Pump self-test. It is more suitable for the fire pump directly from the municipal pipe network water absorption.
3. The constant speed self-check method is suitable for the water absorption of the fire pump from the fire pool, and the layout of the pipeline should be reasonably considered in the design. There are some problems in operation, which may cause overpressure very soon, so it is not suitable for engineering application. The normal speed self - test and low speed self - test have their own characteristics.
In the process of use, it is necessary to regularly carry out manual inspection and maintenance of the fire pump, because the fire pump self-inspection can not completely replace the manual maintenance and management of the fire pump.
