Fire pump knowledge and maintenance

 Fire pump as the name implies, the pump used on fire fighting, fire pump is the introduction of foreign products, according to different classification methods into different types, with its fully sealed, non-leakage, corrosion-resistant features, widely used in environmental protection, water treatment, fire fighting and other departments, is used to pump all kinds of liquids.
In the daily maintenance of the fire pump, we need to do the following requirements: we need to make sure that the inlet and outlet pipes, the components of the controller, the diesel engine system, etc. can work normally, and make sure that the power part is firmly connected to the pump. We also need to check the pump room, fire pump system, the opening state of each valve, to ensure that the pump room has good heat dissipation conditions, to ensure that the pump components are in normal working condition.

After understanding clearly the requirements of maintenance of fire pumps, what are the specific contents of maintenance?
Check the sealing condition of the pump set daily, and the fire pump installed horizontally should not drip more than one drop of water per second before it is put into operation.
Check the fire pump system and electrical control part every week, and ask the pump set to be in good condition.
Weekly inspection of the pump room cooling and ventilation facilities, to ensure that the ordinary electric pump room is not less than 4 ℃, diesel fire pump room is not less than 2l ℃.
In addition to observation, the actual operation every week is also important. In order to avoid the sudden situation of the pump in emergency, so the pump should be run every week to observe whether the pump seal is secure and whether the pump body is overheated; observe the maximum flow rate of the pump flow meter, whether it is 150% of the rated flow rate.

After the requirements and content are understood, it is the method, as follows.
Fire pump weekly fire pump run at least once, running time electric pump not less than 10min, diesel pump start not less than 30min, check whether the water pressure out of the pump is in line with the requirements.
Fire pump every week before the fire pump running, check whether the pump set is intact. Requirements: ① pump suction, hand, bypass tube can all open; ② pump group no leakage; ③ into and out of the pipe pressure gauge is normal; ④ fire fightingpool full of fire fighting water storage.
Before running the fire pump every week, check whether the electrical control part is intact. Requirements: ① power switch indicator is normal; ② switching and conversion indicator is normal; ③ power backup start and isolation switch is closed; ④ alarm feedback signal indicator is not lit and normal indicator is on.
Before running the fire pump every week, check that the main and standby power supply switch is normal, check the standby power supply to see if the pump can be put into normal operation within 30s; check whether the standby pump can be automatically switched into operation.
Check whether the gate valve, check valve and water hammer elimination device on the outlet pipe are normal.
Clear the debris at the population of the suction pipe to prevent blockage.
Open the end water test device or fire hydrant water release, check whether the pump can be started normally.
