Reading: The fire pump is not watery. “The consequences are serious.†Before this, a fire broke out in a certain area. At 22:17, the fire brigade arrived at the scene of the fire. The fire broke out at the cardboard box under the lamp in the 1803 room storage room. After being rescued by a fire extinguisher at the scene, the fire was saved. Basic extinguishment, but there is still a smoldering phenomenon accompanied by an open flame at the bottom of the storage room. When the fire officers and soldiers prepared to extinguish fire, they found that the fire protection pipe network of the unit building was not water-free and could not normally use the wall-type fire hydrant inside the building to fight the fire. Fire officers and soldiers can only use the fire extinguisher inside the fire unit to fight. At the same time, the Riverside Fire Fighting Squadron immediately reported to the command center of the detachment the water network of the fire control network on site and requested reinforcement. According to the situation on the site, fire officers and soldiers divided into two groups. A group of fire officers evacuated the residents in the fire unit building, and a group of people organized water supply for fire fighting. Since then, the district’s fire-fighting officer arrived and the fire pump fault was removed and enabled, and the water in the floor was continuously supplied. At 23:30, the fire at the scene was controlled.
Atlantic Pump Analysis: The reason why the fire pump started to fail was because the fire pump voltage was unstable and it started to trip once it was started. It was not discovered until the engineering director was notified of the cause. At the rear, the circuit of a part of the building was closed. At the same time, the guards were arranged to guard at the tripping place. The water that was normally started and supplied was held by hand. The reason why the fire pump did not make a sound, and the key moment became a prop, was actually attributed to the safety awareness of the residential property.
The reasons why the fire pump does not reach the water are as follows: 1. The air that is not filled with water or the import pipeline is not pumped out; the solution that the centrifugal pump does not emit water is to continue the irrigation or to pump the air inside the inlet pipe.
Reasons why the fire pump is not watered. Second, the lift required for actual working conditions is too high. The centrifugal pump has a low lift head that does not meet the working conditions. Solution: Replace the pump with higher lift.
Reasons why the fire pump is not watered. 3. Absorption of air in the suction pipe or sealing device; Solution: Block or repair the leak, seal or replace the seal.
Reasons why the fire pump is not watered. IV. Improper rotation of the inlet and outlet of the pipeline centrifugal pump in the direction of import and export of the pipe or improper wiring of the motor. The direction of rotation of the water pump is not correct. Solution: Change the direction of the entrance and exit of the motor. Change the direction of rotation of any two wires. .
Reasons why the fire pump is not watered 5. The pump speed is too low; the solution for the centrifugal pump is not water: increase the pump speed.
Reasons why the fire pump is not watered 6. The bottom valve is rusted and the inlet or impeller channel is blocked; Solution: Repair the bottom valve, remove debris, and add trash racks to the inlet.
Reasons why the fire pump is not watered VII. The suction pipeline of the imported pipeline is too long. Solution: Reduce the installation height of the pump, or reduce the elbow valve components on the suction pipeline, and shorten the pipeline length.
Reasons why the fire pump is not watered. VIII. The impeller is seriously damaged and the clearance of the leakage ring is reduced. Solution: Replace the impeller and reduce the leakage ring.
Reasons why the fire pump is not watered 9. The impeller nut and the key escape; Solution: Repair the fastening.
Reasons why the fire pump is not watered 10. The suction pipe is not installed correctly, causing the airbag to be stored in the pipe. Solution: Modify the suction pipe.
Reasons why the fire pump is not watered 11. The impeller is installed in reverse; Solution: Reassemble the impeller.
Reasons why the fire pump is not watered. 12. Insufficient depth of the inhalation nozzle, inhalation of air in the pump; Solution: Increase the depth of flooding, or put a piece of wood around the surface of the suction pipe.
