Pump protection system To improve the service life and operational safety, magnetic pump can provide one or more of the following safety protection device. Today's latest valid order information free to send! Morning latest buyers information free to send! Punch grab Rob here! (i) Bearing Condition Monitor If required by the user, some internationally renowned manufacturers can configure the non-contact bearing condition monitor to prevent bearing wear failure, coupling decoupling, rotor jam and power system failure. (2) Motor Power Monitor The motor power monitor monitors the motor power to avoid low flow or dry operation. (3) Temperature Probe Use a temperature probe (RTD) to monitor the temperature of the baffle to reflect changes in pump condition during operation. Can prevent the dry pump operation, internal and external bearings wear and tear, severe cavitation, stuffy pump, pipe pump stuck and system overheating. (4) differential pressure switch with differential pressure switch to monitor the pump outlet pressure changes, to prevent the pump dry run, serious cavitation, boring pump, pump stuck. Especially for container emptying / tank truck unloading and so on. (5) The second layer of protection â‘ pressure-tight magnetic coupling box isolation sleeve outside the magnetic coupling box. For high-system pressure delivery of some highly toxic or flammable chemicals, the box should be a pressure-tight container, the design and test pressure value and the pump hydraulic end; and the pump shaft and the magnetic coupling box Throttle bushing and mechanical seal should be set (commonly known as secondary seal). APl 685 recommend this type. â‘¡ double isolation sleeve structure When using double isolation sleeve structure, the outer isolation sleeve design and test pressure value should be the same with the pump hydraulic end. (6) Liquid Leak Probe For a magnetic pump with a second layer of protection, a liquid leak probe should be provided. For pressure-sealed magnetic coupling box structure of the magnetic pump, when the isolation sleeve rupture or due to other reasons, the liquid into the magnetic coupling box, the probe will alarm; for the double isolation sleeve structure of the magnetic pump, when the isolation sleeve rupture Or for other reasons, the liquid enters the cavity between the inner and outer isolation sleeves, the probe will alarm.
