When we use Portable Fire Pump Manufacture, we will observe its operation from time to time. Firstly, we will judge whether the quality of Portable Fire Pump Manufacture is good according to the operation of the pump. Secondly, we will observe the operation of Portable Fire Pump Manufacture from time to time. What are the operating requirements of the pump?
1, the fire pump should be sealed in place, the seal at the shaft seal should meet the requirements, no leakage.
2. The outlet pressure is higher than or equal to the rated outlet pressure, and the flow meets the requirements.
3, fire pump in the start of a little vibration, this is a normal phenomenon, but the vibration should meet the standard.
4. The outer surface temperature of the bearing seat is lower than 75℃, and the temperature rise is lower than 35℃.
Do not feel that the fire pump can operate normally, ignore it, in fact, if it does not meet the requirements, if there is a problem later is also very troublesome, so the operation of the pump must meet the requirements.
Fire pump is mostly used in fire rescue, but sometimes there will be too much power consumption in use, what is the reason for its excessive power consumption?
1, bearing lubrication is incorrect or bearing wear.
2, the water head is lower than the rated value, pumping too much liquid.
3. Liquid is heavier than expected.
4, the direction of rotation is not correct.
5, impeller damage.
6, shaft bending.
7, the running gap between the wear rings is not correct.
8. Stuffing box is not properly packed.
9, rotating parts bite to death.
10. Too high speed.
Therefore, during the use of the fire pump, it is necessary to carry out regular inspection and maintenance, so as to avoid the failure of the pump body in the fire rescue, can not work normally or reduce the efficiency of the work, resulting in unnecessary losses.
