Title:
LOW-POWER-CONSUMPTION MECHANICAL PUMPING UNIT INCLUDING A VERTICAL MOTOR
Document Type and Number:
WIPO Patent Application WO/2014/045172
Kind Code:
A3
Abstract:
The invention relates to a hydraulic mechanical pumping unit including a vertical motor for strokes greater than 3m, which only requires a maximum power of between 746 and 5600 watts for operation. The unit comprises a frame including the hydraulic oil tank, a compartment or housing for electrical, mechanical and hydraulic components, the motor, the fan and the carburettor, all of which are housed vertically, thereby allowing the unit to be installed in smaller spaces, minimising connections and requiring less equipment, while allowing all of the components thereof to be protected from the environment (sun, rain, water). The unit includes an assembly base plate serving as a support for the solenoid valve which, in turn, allows the hydraulic oil to be distributed through three different channels, namely: a first channel which directs the oil towards the hydraulic actuator; a second channel which conveys the oil towards a relief valve which directs the oil towards the tank; and a third channel which conveys the oil through the solenoid valve towards a hose that conveys same to the filter, from where the oil is sent to the radiator and then returned to the tank. In order to simplify operation, the flow-control valve, the pressure gauge and the cut-off ball valve are housed in the inlet of the pedestal.
