PURPOSE:To permit the exchange of rubber bag and the regulation of oil level even during the operation of compressor by connecting circuit connected in parallel to (n+1) numbers of transfer barriers through valves to each of two kinds of head tanks for urgent water releasing and oil level regulation. CONSTITUTION:Two kinds of head tanks 52 and 51 for urgent water release and for oil level regulation are provided, and the transfer barriers 21-23 are provided, as shown in Fig., of which the total volume of two barriers is such that the amount of oil between both levels, high-level alarm and abnormal-low alarm, can sufficiently covered. And, three barriers are connected in parallel by placing the valve 31 and 36 and then connected to each the head tanks 51 and 52 and their lower parts are connected to the pump 9 through the valves 37-39. Thus, the exchange of rubber bag and the egulation of oil level of the head tanks can be performed closing or opening the necessary valve during the operation of compressor. |
