Couplings shaft preparation

Couplings must be installed properly if they are to operate satisfactorily. This section discusses shaft and coupling preparation, coupling installation, and alignment. 

When specified, a spare rotor shall be prepared for vertical storage. The rotor shall be supported from its coupling end with a fixture designed to support 1.5 times the rotor s weight without damaging the shaft. Instruetions on the use of the fixture shall be included in the installation, operation, and maintenanee manual. 

Fig. 22.24 Illustration of the spray drying tower. The feed is pumped from the vessel (2) through the pipe (5) to the LamRot (4), which is coupled with the motor (5) by the shaft. The fans (6, 7) and heater (8,9) prepare the air for the drying process. The main product is collected in a vessel (10) under the conical part of the tower. The drying air still containing small product particles leaves the tower through the pipe (11). The exhaust air than passes a cyclone (12) and a pocked filter (13) subsequently. The suction fan (14) controls the pressure within the spray tower. (7) and (14) are frequency controlled...
