Title: Method of and means for priming a rotary liquid pump
Inventor: ROBSON ANTHONY DINWOODIE
IPC: F04C14/06
Filed: 1962-04-11
Abstract: 963,861. Priming pumps; rotary pumps. BRITISH OXYGEN CO. Ltd. March 28, 1963 [April 11, 1962], No. 13918/62. Headings F1C and F1F. A rotary liquid pump is primed by rotating it by means of a turbine rotor connected to the pump shaft and driven by directing a number of jets of a compressed gas against the blades of the rotor. A pump (not shown) for pumping liquefied gases having boiling points substantially below atmospheric temperature, such as liquid oxygen, is driven by an electric motor 10 through a shaft 11 on which is mounted a fan impeller 12 for cooling the motor. The impeller 12 is surrounded by an annular manifold 15 provided with nozzles 19 and connectible at 17 to a source of compressed air or other compressed gas, whereby jets issuing from the nozzles and striking the fan blades 13 rotate the wheel 12 and hence the pump at a speed sufficient to prime the pump by clearing any vapour from it. The motor 10 can then be switched on and the supply of compressed gas discontinued. After pumping has been stopped and the motor 10 has been switched off, the pump can again be rotated by means of the compressed gas jets so as to remove as much residual liquid as possible and thereby minimize the amount of vaporization taking place when the pump is out of use. The deposition as ice on the working parts of any water or water vapour contained in the liquefied gas is also avoided.
