Fire pump is an important equipment to ensure fire safety in our daily life, inevitably in the process of use there will be a variety of wear and tear, consumption or power, etc. will produce certain changes. Why the fire pump in the process of use, power consumption will increase?
The main reason for the increase in power consumption is divided into two, one is the wrong way to use, the second is the wear and tear of parts over a long period of time.
1, the wrong direction of rotation, first check whether the correct direction of rotation.
2, the liquid is heavier than expected. Pumping a higher density of liquid will consume more current, check the specific gravity and viscosity of the liquid.
3, The speed is too high. Check the winding voltage of the motor or the steam pressure transmitted to the turbine.
4, The bearing is not properly lubricated or the bearing is worn. Bearings need lubrication, no lubrication will increase the friction, but also consume current, in the case when there is good power to check the lubrication of the bearings or whether the wear, if the wear is serious, replace the bearings if necessary.
5, the impeller is damaged, check the impeller and replace it as required.
6, The working clearance between the wear rings is incorrect, check whether the clearance is correct. Replace the wear rings of the pump casing and/or impeller as required.
According to the above points, we can obviously see that the daily maintenance and upkeep of the pump is very important in the daily use of the fire pump, and each part needs to be checked regularly to ensure that the pump can work normally and efficiently.
