用水或油作为工作介质的液压泵广泛采用中小型异步电机来驱动,我国每年约有200～300万kW的电机被用于驱动液压泵。1986年4月,机械电子工业部济南铸锻机械研究所获得了中国专利局授予的泵电机组专利,该专利中提出了我国Y系列电机派生的Y_(YB)系列液压压泵专用电机的相关尺寸,可满足柱塞泵、叶片泵、齿轮泵、摆线泵等各种电机组的安装要求,也适合某些离心泵组成的泵电机组。用该种电机装的泵电机组,一经投放市场,就受到了用户的欢迎。一、泵—电机传动装置与泵电机组
Hydraulic or hydraulic oil as a working medium is widely used in small and medium-sized asynchronous motor drive, our country each year about 200 ~ 3000000 kW motor is used to drive the hydraulic pump. In April 1986, Jinan Casting and Forging Machinery Research Institute of the Ministry of Machinery and Electronic Industry won the patented pump and motor unit granted by the Chinese Patent Office. The patent proposed the correlation of the Y_ (YB) series hydraulic motor for Y series motors derived from our country Size, to meet the plunger pump, vane pump, gear pump, cycloid pump and other electrical installation requirements, but also for some centrifugal pumps composed of pump motor. With the motor installed pump motor, once put on the market, it has been welcomed by users. First, the pump - motor drives and pump motor group
