Correctly grasping the operation method is an important factor for prolonging the Foam Pump(KEXON) life and reducing economic losses.
(1) For submersible Foam Pumps
Before starting, some necessary checks should be done: whether the rotation of the foam pump shaft is normal, whether there is stuck or not; whether the position of impeller is normal; whether the cable and cable plug are broken, scratched or broken, etc. In operation, attention should be paid to observing the change of voltage, which is generally controlled within the range of (+5%) of rated voltage. In addition, the position of the pump in the water is very important. It should be selected as far as possible where there is plenty of water, no silt, and good water quality. It should be suspended vertically in the water, and not allowed to be placed horizontally, so as to avoid falling into the mud or being blocked by suspended substances, leading to a sharp reduction in the output of water or even not pumping.
(2) For Self-priming Foam Pumps
As far as possible, it should be placed in a well-ventilated place to run in order to facilitate rapid heat dissipation and reduce the temperature of the motor. Otherwise, it is easy to burn the motor if it runs for a long time. For example, when a farmer uses a self-priming foam pump, the coil is burnt because the plastic film covering the motor is not removed. In addition, before starting, it is necessary to check the water storage in the pump body, otherwise, it will not only affect the self-priming performance, but also easy to burn the shaft seal components. Under normal conditions, the water should be discharged 3 to 5 minutes after the start of the pump, otherwise the machine should be stopped immediately for inspection.
(3) Maintenance of Foam Pumps
When the foam pump breaks down, don't disassemble it by yourself. Because when they disassemble, first, they don't know where the fault is and cause blindly disassembly; second, they often damage the original intact parts without special tools. The best way is to have experienced and large-scale maintenance points, and timely replacement of "over-age" parts and some vulnerable parts. Normally, the pump should be repaired every six months to eliminate the work with "disease".
