| Abstract: | After an introduction of the front-mounted air-balanced pumping units in China and abroad, in the light of the problems with the application of these units, measures for improving the unit are put forward,including adding the mechanism for varying the offset angle, eliminating the negative tangential fore, reforming the structure of the horsehead, adopting the high-slip motor, providing the protecting device for loss of load and adding anti-freezing measures. In addition, suggestions for popularizing these improve ments are presented. |
