What causes the excessive power consumption for the fire pumps?
Fire pumps, as indispensable equipment for fire protection, must be paid more attentions. However, people who are in daily life will find that power consumption varies for various reasons during the operation of the fire pump. So, what are the reasons for the excessive power consumption of fire pumps?

1. The incorrect rotation direction of the fire pump;
2. The impeller of fire pump is damaged;
3. The rotating parts of the fire pump are stuck;
4. The fire pump shaft is bent;
5. The head of water pump is lower than the rated value one;
6. The liquid pumped by the fire pump is too much;
7. The weight value of the pumping liquid is greater than the expected value;
8. The fire pump bearing is not lubricated and the lubricant is not used correctly;
9. The fire pump bearing is seriously worn;


 
These nine reasons are the root causes of the excessive power consumption of the fire pump. However, as long as the daily maintenance of the fire pump do well, such as correct adjustment of the rotation direction; always check the degree of wear of the impeller, effective replacement; check the lubrication level of the fire pump bearing, if it is necessary to add lubricant, etc. All these measures can be done to effectively avoid the power consumption.
