Correct maintenance of fire pumps

When it comes to correct maintenance of fire pumps, there are a lot of notices. Some people only know the importance of regularly checking the equipment, but they don’t know the frequency, today, I will tell you daily maintenance, according to the day, month and year, this way also applies to 90% of fire pumps.

With “day” as the unit of account, fire pump maintenance procedures:

1. Before starting the motor, turn off the power, the manpower rotates the motor several times and make a record.
2. It is recommended to run at least once a week for no less than 15 minutes, regardless of the fire pump environment.
3. Regularly inspect the pump body every day. Pay attention to remove dust, dirt, oil, water and other debris from the motor and the motor vents.
4. timely adjust the leakage of the packing and seal.
5. check the cooling water and shaft seal water supply system, pipelines and pumps for the leakage phenomenon, if it leaks, should be repaired immediately.

   

With “month” as the unit of account, fire pump maintenance procedures:

1. Check and adjust the pump and motor to ensure concentricity.
2. Check the condition of lubricants to see if they need to be supplemented. In particular, pumps are frequently used in the chemical companies, motors must be checked every month. If necessary, they can shorten the time and check once every half month.
3. Measuring vibration and noise.
4. Check whether the gap in the rotating fit part is too large and causes the phenomenon of relaxation.
5. Press the “Scrutiny” button, the fire pump automatically detects three minutes, When there are no abnormalities, it will automatically stop.

   

With “year” as the unit of account, fire pump maintenance procedures:

1. check the rotating part of the wear, as for different application environments, the fire pump operating frequency varies. In the early years, the wear of rotating parts of fire pumps was almost checked every month, but with the advanced materials, the fire pumps became more and more durable. Nowadays, 90% of the regular fire pumps circulating in the market only need check once a year, even if the fire pump operates at a high frequency, it can be used with confidence.
2. Check the gap between the impeller and the seal ring, as well as the cavitation and erosion of the impeller and its flow path components.
3. Check the wear of bearings and mechanical seals, and perform effective repairs for different degrees of wear.
