摘要： A method of inhibiting combustion within a vacuum pump is provided. The method steps include monitoring and composition of a fluid within the pump and supplying purge gas to the pump to inhibit the onset of a combustion of the fluid. There is also provided a pumping arrangement comprising a vacuum pump (1) together with means (8) for supplying purge gas to the pump. Sensor means (21a, 21b, 21c) are provided for outputting a signal indicative of the onset of a combustion condition within the pump. Control means (22) receive the signal and, in turn, actuate the supply means (9) dependant on the signal received.

摘要： Apparatus is described for inhibiting the propagation of a flame front ignited by a pumping mechanism drawing a waste stream from a process chamber. A combustion chamber comprises an inlet for receiving the waste stream exhaust from the pumping mechanism and means for generating a flame for burning a flammable component of the waste stream. A pressure detector detects a pressure at a location through which the waste stream is drawn by the pumping mechanism, and a flame detector detects the presence of a flame in th combustion chamber. A controller regulates the delivery of at least one process fluid to the process chamber if the detected pressure is greater than a pressure above which the flame front can be sustained by the waste stream, or if there is no flame present in the combustion chamber.
