The NIKKISO E Monitor has been developed to determine the condition of the hermetically sealed pump bearings during pump opera. tion The position of the rotor is monitored while the pump is operating Furthermore the technically state of the art monitor can be. used for preventive maintenance relating to bearing wear. Separate wear display for axial and radial bearings. Uneven wear of the front or rear bearings,Directional monitoring. Advantages, The directional display indicates whether the pump is rotating in the wrong direction and makes measurements of the.
phase rotation during commissioning unnecessary, Since the E Monitor receives its power supply by means of the motor s terminal box external wiring is omitted. The unit is attached to the pump and is ready for use after the pump is commissioned. E Monitor operating principle,V axial wear, Sensors integrated into the stator transmit is registered by the sensors Any change bearings 5An LED illuminated in yellow. the measurement data to the monitoring in the status of the pump bearings is indicates to the operator that the pump. unit The rotor assembly is moved along displayed to the operating personnel by should be checked at the next regular. the radial or axial position in the case means of a simple and clearly arranged system shutdown If the LED lights up in. of bearing wear As soon as the rotor LED display An LED that is illuminated red the pump should be immediately put. leaves its operationally safe position this in green indicates a good state of the out of operation and checked. rear axial clearance front,V axial wear V radial wear. rear axial clearance front down up,V radial wear,NIKKISO Non Seal Pump Components 09. Bearings modular system, NIKKISO bearings are slide bearings The materials used.
range from various carbon graphites through polytetra. fluorethylene PTFE to silicon carbide The use of CG93 Shaft protection sleeves Bearing. a mixture of carbon and silicon carbide enables increased hard coated carbon graphite. protection against wear without any brittleness, The bearings are liquid lubricated and designed with Silicon carbide. a groove for an improved supply of lubricant, Depending on application the shaft protection sleeves. are either plated with chromium or finished with a hard Shaft. ened material, The axial thrust washers made of hardened material. or chromium plated limit the movement of the shafts. under disruptive conditions to reduce the risk of damage. to the pump Axial thrust washer,hard coated, For a simplified installation process the front and rear. bearings are identical shaft protection sleeves are identi. cal and thrust washers are also identical to one another. Automatic axial thrust balancing,The hydrodynamic operating prin.

Reliable motors, Protection against leakages through seal welded and 100 leakage proof corrosion resistant linings. They ensure that the supplied medium does not come into contact with the stator windings or the core. of the rotor, The complete outer side of the motor is encapsulated in a second leak proof protective shell. Increased operating reliability through the absence of dynamic seals. Motor cooling and bearing lubrication through the supplied medium that is circulated in the area. between the rotor and stator lining, Motor windings and insulation are specially designed and used as an integrated pump component Thus.
a design service lifetime is achieved which corresponds to at least that of conventional air cooled motors. Integrated thermostats at the overheating points of the windings switch off the motor in case of. overheating Control of the winding temperature mainly through fluid temperature as well as through. the use of a cooling jacket, Direct integration of the motor into the centrifugal canned pump ensures not only environmental. protection but also safety at the plant, All parts of the pump are designed for easy and fast maintenance Therefore expensive downtimes. can be minimized,NIKKISO Non Seal Pump Components 11. 12 NIKKISO Non Seal Pump Pump Types,For a wide variety of requirements.
