The use of magnetic pump and troubleshooting

2012-08-16 Reads : 113

Cautions

A magnetic pump bearings, cooling and lubrication is to rely on the transmission medium, so the absolute prohibition of the air operation, while avoiding the start of the work half-way power outage after the "no-load operation.

2 is transported media containing solid particles, the pump inlet to add the filter: If the containing ferromagnetic particles need to add a magnetic filter.

3 pumps in use in the ambient temperature should be less than 40 ℃, motor temperature rise shall not exceed 75 ℃.

4 transport medium and its temperature should be in the range of pump material allows. The use of engineering plastic pump temperature <60 ° C, use temperature of the metal pump <100 ℃, auxiliary send suction pressure is not greater than 0.2MPa, the maximum working pressure of 1.6MPa, the density is not greater than 1600 kg/m3, particle size less than 30X10-6 m / S without hard particles and fibers in the liquid.

5 for the transmission fluid is easy to precipitate crystalline media, the use of the inch cleaning, drain the pump fluid.

Magnetic pump is run for 500 hours after dismantling the bearings and end snap ring wear inerting conditions, if the bearings and bushings gap is greater than 0.5 ~ 1mm, impeller, axial movement of 1.5 ~ 2mm, replace the bearing and shaft to move the ring.

Fault and exclusion

Failure in the form	Causes	Remedy
Pump no water	Pump reversal Peng water pipe leak Impoundment too little of the pump chamber Voltage is too high, the slip coupling when the start Suction is too high	Change the electrical wiring Community must leak Increase the storage capacity Adjusted voltage Reduce pump installation location
Inadequate flow of	Inhalation diameter too small Impeller duct obstruction Head is too high Speed ??is too low	Swap the inlet Cleaning impeller To open a large outlet valve Restore summer rated speed
Head is too low	The amount of traffic Speed ??is too low	Off a small outlet valve Restore the rated speed
矂tone is too big	Axis serious wear and tear Sleeve serious wear and tear Drive magnet cup and isolated sets of contacts	Replace the pump shaft Replace the bushings Removal of pump head re-assembly
Leakage	0-type sealing rings of damage	Replacing the 0-type sealing rings of
