The pump body has a dripping phenomenon, but it is not very serious. How to deal with it?
+
Actions: 1) Identify the source of dripping (seal, gasket, or casing), 2) Monitor frequency and volume, 3) If seal weepage, it may be normal for mechanical seals — check if within acceptable rate, 4) If increasing, plan seal replacement during next maintenance, 5) Always follow safety protocols for chemical handling.
What is the reason for the abnormal smell emitted by the motor during operation?
+
Causes: overheating windings, insulation degradation, bearing grease burning, or electrical arcing. Solutions: shut down immediately for safety, check motor temperature, inspect bearings and lubrication, test winding insulation, and look for signs of electrical damage.
What are the reasons for the stalling phenomenon during the operation of the pump?
+
Causes: bearing seizure, impeller jamming from debris, misalignment, or motor winding issue. Solutions: shut down immediately, manually check if shaft rotates, inspect pump interior for foreign objects, check bearing condition, and verify motor windings.
Why does the motor have over - heat protection and how to deal with it?
+
Causes: overload, low voltage, high ambient temperature, blocked ventilation, or frequent start-stops. Solutions: verify load is within rating, check supply voltage, ensure motor cooling vents are clear, reduce ambient temperature, and reduce start frequency or use soft start.
What is the reason for the unstable flow rate of the pump and how to solve it?
+
Causes: suction level fluctuations, air entrainment, partially blocked impeller, or unstable system pressure. Solutions: stabilize suction conditions, check suction line for air leaks, inspect and clean impeller, and consider accumulator or dampener installation.
What is the reason for the surging of the pump during operation and how to solve it?
+
Causes: pump operating in unstable region of curve (too low flow), rapid system pressure changes, or air/vapor in the fluid. Solutions: increase minimum flow bypass, ensure system has proper pressure control, bleed air from system, and verify pump operates within stable range.
