目前,由于能源的紧缺,各国的电费也在不断地提高。我国虽然国情不同,但在电费上涨的趋势方面也是类似的。 在我国仅中、小电机耗电量就占发电量的60％,因此,采用高效,节能的机电产品是合理地使用能源的需要。长输管道的主要耗电设备是输油泵机组,提高其效率,降低电耗自然是各泵站优先考虑的课题。 Currently, due to the shortage of energy, the electricity tariffs of various countries are also constantly increasing. Although our country is different in national conditions, it is similar in the trend of rising electricity bill. In our country, only medium and small motor power consumption accounts for 60% of power generation, therefore, the use of efficient, energy-saving mechanical and electrical products is the rational use of energy needs. The main power-consuming equipment of long-distance pipeline is the transmission pump unit, to improve its efficiency and reduce power consumption naturally is the priority of the pump station.
