摘 要 油田中转站储运系统的油品移动量为加工量的五倍，油库的收付油业务量也很大。可见罐区油品的进出、收付是非常频繁的，由此引发的事故也较多，特别是油罐的油品溢出事故更为屡见不鲜。油品的溢出不仅造成经济损失，污染环境，而且还可能引发失火、爆炸等恶性事故因此，，，，， 关键词：变频器；变频调速；电机；节能 Abstract In transfer and storage system of oil field, the transferred amount of oil is five time as that of produced. Meanwhile, the working load of both oil import and export is extremely big. It is obvious that, oil import and export, income and payout are quite frequent. For this reason, the probability of causing an accident is also high, especially, some accidents which caused by oil overflow are common occurrence. When such an accident happens, what we lost was not only some economic cost, but also the environment we are living in. Moreover, some more terrible accidents like fire and explosion may come with overflow. Therefore, the liquid level parameter of an oil transfer station is one of the most significant craftwork parameters. This system aims at liquid level, such an important parameter, designed basing on existing control experience. Such reduplicate regulation method will lead to a certain amount of energy waste. Here, we control the flux by adopted a frequency converter which can adjust the rotating speed of the motor. That will realize automatic control of liquid level. This system from a set change Pin machine, two set electrical engineering with take a liquid of have the flameproof system to account and some kit equipments constitute. Change the Pin machine technique and tradition of exchanges drag along to move system to compare, make use of change machine to exchanges the electrical engineering carry on adjust soon control, easy realization to adjust of existing electrical engineering soon control, can realization inside big scope of efficiently continuous adjust control, realization speed of precision control. Change machine protection the function be very strong, in the movement the process ability at any time examination arrive various break down, and manifestation break down category, such a
