Pumps rotors

Rotation of the pump rotor, which Is mounted eccentrically In the pump cylinder, traps entering vapor between rotor vane segments. As rotation continues, vapor is compressed then discharged into the exhaust box. Vapors then pass through four stages of Internal oil and smoke eliminators to remove 99.9% of lubricating oil from the exhaust. Oil is then returned to the recirculating oil system.

Fig. 4.1-27 shows a multistage canned-motor centrifugal pump with a separate water-cooling circuit for the motor, such as is used, for example, to circulate carbon dioxide at 300 bar system pressure. The pump rotor is mounted in the motor area the tandem pump stages operate over-mounted on both sides of the bearings. This arrangement is recommended if the required differ-... 

Category 3 Food contact materials and articles which according to their intended use come in contact with food for a maximum of 10 minutes (short time contact). Examples are shaker beakers, milking machine hoses, seals for milk processing equipment, membranes, pistons, faucets, pump rotors, roller coverings and conveyors for fatty foods as well as gloves and aprons worn when handling food.

The risk associated with attempts at production records is that management may be tempted to let equipment run in a potentially unsafe mode in order to avoid a shutdown to conduct maintenance. For example, a pump rotor may become imbalanced, leading to mild vibration of the pump itself. Rather than shutting down the affected section of the facility to repair the pump, management may decide to keep the pump running, thus creating the possibihty of a seal leak and a release of large amounts of toxic or flammable materials.

The reactor coolant piunp shaft break accident is postulated as an instantaneous failure of a reactor coolant piunp shaft. Flow through the afiected reactor coolant loop is rapidly reduced, though the initial rate of reduction of coolant flow is greater for the reactor coolant pump rotor seizure event.

The study of cavitation in cryogenic fluids and various hydrocarbons is being applied to research in centrifugal pumps, turbines, marine propellers, etc. The method of applying this to pumps is shown in the enclosed Figure 15, in which sensing strips are mounted on the pump rotor and connected through electrical leads to a miniaturized electronic control circuit located in the hollow pump drive shaft. The output of this circuit is used to vary the frequency of an F-M oscillator. The...
