Problems solved by technology

[0003] Compared with the corresponding products currently in use, although the machine may have obvious advantages in terms of comprehensive economic effects in manufacture and use, the hydraulic components selected for its hydraulic transmission components and the hydraulic system used are reliable in operation. There are still deficiencies in the indicators that can be achieved in terms of working performance, such as safety and working life, and the low failure and long-life working performance requirements that are necessary for this kind of pumping unit products. At the same time, the main structure of the whole machine also needs to be further improved.
