Problems solved by technology

However, the existing beamless pumping units generally still have large inertial loads, resulting in high power consumption of the motor, and the existing beamless pumping units have a complex structure, many moving parts, high cost, and a large footprint. All of these have greatly limited the popularization and application of beamless pumping units

Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0031] like Figure 1 to Figure 10 The helical pumping unit of the present invention shown includes a mounting bracket 10 , a geared motor 20 , a counterweight 30 and a connecting device 40 . The structure is reasonable, the design is novel, and the volume of the pumping unit is greatly reduced through the close cooperation of the installation bracket, the counterweight and the connecting device.

[0032] The mounting bracket 10 includes a base 11, a front bracket 12, a rear bracket 13, a reinforcing plate 14 and a crossbeam 15, the front bracket 12 and the rear bracket 13 are all provided with mounting grooves 131, and the reinforcing plate 14 includes a firs...

Abstract

The invention discloses a vertical lifting type oil pumping unit which comprises an mounting support, a connecting device, a balancing weight, and a gear motor. By means of the mode that the gear motor directly drives a sucker rod, a walking beam type pumping unit or the pumping unit with a pulley is changed to be in a low-efficiency acting state for a long time, so that the working mode of the pumping unit is matched with the actual load of an oil well, the situation that oil pumping is conducted every time is guaranteed, low-efficiency or even invalid pumping is reduced, and therefore the electric charge expenditure is reduced, the maintenance cost is reduced, and the operation efficiency is improved. The vertical lifting type oil pumping unit is reasonable in structure and novel in design; the size of the pumping unit is greatly reduced through mutual close fit of the mounting support, the balancing weight and the connecting device; and a plurality of groups of vertical rollers andhorizontal rollers are arranged, so that the operation is more stable and the noise is low.

Description

technical field [0001] The invention belongs to the technical field of oil production machinery, and in particular relates to a direct lift pumping unit. Background technique [0002] Pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine". The pumping unit is the most important lifting equipment in the rod pumping system. According to whether there is a beam, it can be divided into a beam pumping unit and a beam pumping unit without a beam. [0003] The beam pumping unit has low transmission efficiency due to the cumbersome transmission mechanism, heavy structure, high motor operating power, high energy consumption, and the beam pumping unit is difficult to adjust stroke times due to structural limitations. Beamless pumping units mainly include wide belt pumping units, linear reciprocating pumping units, sky wheel pumping units and so on. Because the beamless pumping unit eliminates the heavy beam, it is easy to realize lo...
