Problems solved by technology

[0008] Although convenient in several respects, especially in terms of energy efficiency, the machine has the problem of limited efficiency due to the fact that the load of the gas and the engine affects both the motor nut and the screw
This overloading of the nut will lead to overheating and therefore premature aging
[0009] Also, since the screw is under full load, its length needs to be limited and therefore its effective travel needs to be limited
For these reasons, the machines of applicant's previous patent applications were neither able to lift large loads nor to have a sufficiently long service life

Embodiment Construction

[0025] Referring to these drawings, especially figure 2 and image 3 , shows a pumping machine according to the invention. In more detail, the first embodiment of the pumping machine 650 comprises two tubular elements 651, extending perpendicularly and parallel to each other, serving as containers or accumulators for pressurized gas, such as nitrogen or a mixture of air and nitrogen, shown by Fig. Insert appropriate valves not shown. Tubular elements 651 are interconnected to each other at the top by connecting elements 652 (e.g. brackets) and fixed at the bottom to Figure 4 The support structure (eg, pedestal) shown. The machine 650 also comprises rolling means 655 such as pulleys adapted to support cables for lifting loads, the rolling means 655 being attached to slide means 657 sliding in a guide 653 in the center of the tubular element 651 Inner and along the tubular element 651 extends a predetermined length.

[0026] Furthermore, the machine 650 comprises, between ...

Abstract

The pumping machine (650, 750) comprises: at least two tubular elements (651, 751) containing pressurized gas and extending parallel in a vertical direction and interconnected between them by means of connecting elements (652, 752); and An electromechanical lifting system (600, 700) comprising: a first cylinder (601, 701) interconnected to a tubular element (651, 751) and comprising a piston (601b, 701b) capable of a compressed substance; and a screw (602, 702) having a vertical axis Y coincident with the axis of the pumping machine (650, 750). The screw (602, 702) is inserted in a second thrust cylinder (658, 758) slidingly connected in the first cylinder (601, 701), having a first end fixed to the connecting element (602, 702) (602b, 702b) and a second end (602a, 702a) configured to slide within the thrust cylinder (658, 758) and covered by lubricating oil and cooling including the covered piston (601b, 701b) Chambers for oil (605, 705).

Description

technical field [0001] The invention relates to a pumping machine. [0002] In particular, the invention relates to a pumping machine of the type having an electromechanical lifting system for lifting a load. Background technique [0003] As we all know, a pumping machine is a working machine that uses mechanical handling components (rotary or linear motion) to lift or otherwise move or collect fluid material. This type of pump is suitable for pumping water from wells of considerable depth. Cylinders, such as hydraulic cylinders, are commonly used in the mechanical components of such machines to take advantage of the pressure of the fluid supplied by the pump for the transmission of force. These hydraulic or pneumatic cylinders have the advantage of being simple and economical in construction, accumulating and reusing energy through special pressure vessels, but only if their application has low requirements for repeatability of operating speed and low positioning accuracy...
