查询词典 bleeding pressure

Applied to adjust the casing pressure for ESP wells, it automatically discharges through the bleeding valve, the casing gas into oil/gas manifold, for the purpose of controlling the reasonable submergence depth of ESP intake, and preventing the shut-down of ESP due to gas lock or under-load. This not only ensures the normal pump operation but also enhances the pump efficiency and production rate.

So in this paper based on the characteristics and the optimum state theory of the vehicle, some kinds of control schemes are compared and discussed, and the fuzzy PID control scheme is adopted at last. The relation between air-cushion pressure and fan rotational speed on the optimum driving state is studied. The cushion pressure is used as controlled variable and the fan revolution is used as regulated variable. And transducer and fan motor are actuators.Based on the structure and operating properties of half-tracked air-cushion vehicle, the control system scheme and structure are presented. A control scheme using the self-tuning PID fuzzy logical controller is adopted. Fuzzy rules are set up and some researches have been done for fuzzy tuning method. At the same time the real-time measurement scheme by computer control is proposed, and electric circuits are designed. In the control system of half-tracked air-cushion vehicle cushion pressure P〓 is used as controlled variable and the fan speed n〓 as regulated variable.
