SUBMERSIBLE PUMP

 

  Mechanics maintenance:
     Take out the rubbish from pump housing, check the impeller for smooth rotation.
     Check the working status of pump: pressure, flow, vibration, noise… Adjust or replace details: bearing, joint, axle, impeller… if necessary.

 

 

 

 

 

 

 

Motor maintenance:  

          

  

Check the working status of motor, electrical wire by measurement: voltage, current, resistance, insulation, water contact rod… Adjust or replace details or even rewind motor if necessary.

Taking out the air filter, use high pressure air to blow out the dust and re-mount air filter.

    

Replace with new air filter if the old one can not be recovered.

 

 Mechanics maintenance:

   Check the working status of machine: pressure, flow-rate, vibration, noise… Adjust or replace details: bearing, joint, axle, impeller… if necessary.
   Check the tautness of belt, adjust if loosened.
   Change with new belt if the old one broken or get worse.
   Check the status of joint, seal. Fill oil in additional or change with new oil if necessary (normal frequency: 1 time/3 months).
   Check the safety valve, adjust or replace if necessary.
   Check the working status of pressure gauges, adjust or replace if necessary.

 

Motor maintenance:

   Check the working status of motor, electrical wire by measurement: voltage, current, resistance, insulation, water contact rod… Adjust or replace details or even rewind motor if necessary.

 


 

 

CHEMICAL DOSING PUMP

                                                                                

 

Technology maintenance:

    

Check & clean the filter set, suction hose of pump.

    

Check the flow-rate of pump, adjust for suitability if necessary.

 

Mechanics maintenance:

    

Check the working status of pump: pressure, flow, vibration, noise… Adjust or replace details: bearing, joint, axle, impeller… if necessary.    

 

  Check the joint, add more oil or replace if necessary (period: 1 time/3 months).
