A new generation of Linear motor-driven pumping units has been installed in Daqing Field. During the National Day mid-autumn Festival holiday, 11 fourth-generation tower pumping units independently developed by Daqing Field Equipment Manufacturing Group were put into operation.

     It is reported that the fourth-generation tower pumping unit of most parts (reduction drum, lifting belt excepted) are independent intelligence, with independent intellectual property rights, a total of 8 patents. 

     This kind of pumping unit adopts permanent magnet motor directly connected with reduction drum to drive the lifting belt to move back and forth, which can save 20%-30% electric energy, and also can eliminate harmonic pollution and save production cost for users. In addition, the 4th Generation Of New Tower pumping unit is operated by remote control, mobile phone APP and hand-held remote controller, and the parameter adjustment is simple. Notice that the pumping unit uses a permanent magnet motor directly connected with a reduction drum to drive the lifting belt to move back and forth, and it is well known that the linear motor is a kind of permanent magnet motor, and the straight-line motor can provide straight-line reciprocating motion without any intermediate device, so if the fourth-generation tower pumping unit uses a straight-line motor is reasonable, if it does not use a straight-line motor, xiao Bian felt that the relevant departments can introduce the device in future products. 

     In addition, the linear motor has already been used in practical cases in pumping units. The pumping unit driven by the linear motor is a new type of pumping unit, which directly uses the linear reciprocating motion of the linear motor to drive the pumping rod up and down, compared with the traditional pumping unit, it can save 20%-40% electricity when pumping the same amount of oil in the same time. 

     Kunshan's linear motor products mainly include iron core, no iron core and no slot linear three categories, can provide the standard model of linear motor, also can be customized according to customer needs. The main features of Tongmao linear motor are: high response, low noise, smooth thrust characteristics, high acceleration, high speed, short acceleration and deceleration process, with the application of grating ruler, can also achieve higher accuracy.
