| 摘要 |
<p>The present invention relates to an improved mechanical pumping hydraulic unit for use in oil production or hydrocarbon extraction. The unit is characterized in that it has one motor (1-25), which activates a dual pump (1-15) at one end of the shaft and activates a fan (1-26) at the opposite end of the same shaft. The dual pump (1-15) provides power to the hydraulic power circuit (1-13) and to the hydraulic recirculation circuit (1-14). The motor (1-25), along with the pump (1-15) and the fan (1-26), are inside a metal structure (1-8), or focusing element, which serves to propel air sent by the fan (1-26) through the radiator (1-14-3) and to protect all the components of said unit. The metal structure (1-8) contains other components of said unit, such as a tank (1-3) for the hydraulic oil, a compartment or casing for the electrical components (1-5) and a compartment or dry chamber (1-2) for the hydraulic instrument panel (1-7).</p> |
