Methods and approaches to explore the reliability of magnetic drive pump operation:
When the positive suction head is low, the inlet line should be as short as possible to prevent cavitation. The inlet line shall be properly sized to ensure that the flow rate does not exceed 3m/s; When transporting vaporizing fluid or liquefied gas, ensure that the flow rate does not exceed 3m/s; When transporting vaporizing fluid or liquefied gas, ensure that the flow rate does not exceed 1m/s. The inlet pipe and outlet pipe of the sus magnetic drive pump should be supported to prevent the transfer of additional load to the pump. The magnetic drive pump can not be used as the stress point in the pipeline. It is necessary to ensure that the pipeline system provides compensation measures for thermal expansion.
The outlet line should be installed with a regulating valve to adjust the pump flow and head. When a longer outlet line is used or two pumps are used in parallel, an additional one-way check valve is recommended. In order to achieve continuous operation of the pump, it is recommended to install a return line and install a minimum flow orifice plate to ensure adequate lubrication and cooling of the sliding bearing during continuous operation.
Piping design should take into account pump exhaust. The magnetic pump must work within the specified range. To control the rated flow, it is recommended to install a suitable large flow orifice plate on the outlet pipe. The entire piping system and auxiliary piping should be carefully cleaned to prevent iron scraps, welding slag or other foreign matter from entering the magnetic pump. For newly built piping system, inlet piping should be equipped with filter.
Magnetic pump is suitable for conveying corrosive, toxic, flammable, explosive, expensive or easy to vaporize the liquid. In addition, magnetic pumps are also suitable for conveying high temperature, low temperature fluids and liquids under vacuum conditions. Due to the advantages of no leakage, it successfully solved the problems of running, taking, dripping and leaking in fluid transportation, and has become an irreplaceable product in environmental protection engineering, widely used in petroleum, chemical industry, refrigeration, air conditioning, aerospace, and other fields.
