pumping unit

Pumping unit is a kind of drilling equipment, commonly known as "KeTouJi", through the pressure to make the oil out of the well. When on the pumping unit stroke, tubing elastic contraction and go upward , drive the machine broken down oil production unit go upward , impact sliding sleeve produce vibration; when under the pumping unit stroke,oil tubing elastic extension and go downward, drive the machine broken down production go downward and impact vibration generation sliding sleeve; Reverse part of single valve closed, at the same time, variable-diameter piston assembly seal oil set of annular oil way, still make reverse single valve below form high area, this movement produce a reverse within the strata on the impact of the flow channel.

Technology characteristics

*The using of modular design and virtual manufacturing technology to make product structure optimizated and parts with high degree of "standardization, generalization, seriation"

*Studying on finite element analysis of key structure with stable performance and high reliability

* The speed reducer adopts symmetrical shunt type involute or double circular-arc herringbone gear transmission, with good sealing, low noise, stable operation, reliable and durable.

*The operation is simple, easy maintenance and long service life.
