Abstract

The utility model discloses a speed reducer of a pumping unit and relates to a speed reducer, in particular to a speed reducer on a piston rod of an oil pumping unit. The speed reducer of the pumping unit comprises an oil well pump cylinder and a slide block. A piston is arranged in the pump cylinder and is connected with the pump cylinder in a sliding mode. The slide block is fixedly connected with the piston through an oil pumping rod. The piston and the slide block are both arranged in the pump cylinder. Vent holes are formed in the bottom of the pump cylinder. According to the speed reducer of the pumping unit, the slide block is arranged on the lower portion of the piston, and the vent holes are arranged at the bottom of the pump cylinder, and the load of the mule head suspension center of the pumping unit is reduced by using the air pressure difference of the slide block in the up-down process. The speed reducer of the pumping unit is simple in structure and strong in practical applicability.

Description

A kind of oil pump speed reducer
Technical field
The utility model relates to a kind of speed reducer, particularly the speed reducer on a kind of pumping unit piston rod.
Background technique
Along with the exploitation in oil field, oil reservoir buries more and more darker, and the horse head suspension point load position swabbing pressure that little pump is taken out deeply is larger, and the pumping number of times makes piston larger wearing and tearing and damage occur when frequent easily, causes pump efficiency low or lost efficacy, and can not produce continuously.
Summary of the invention
The utility model is intended to propose a kind of speed reducer that is applied on the oil pumping machine oil pumping pump.
A kind of speed reducer described in the utility model, comprise oil pumping barrel and slide block, described pump barrel inside is provided with the piston that is slidingly connected with it, and slide block is fixedly connected on the piston by sucker rod, described piston and slide block all are arranged on pump barrel inside, and the bottom of pump barrel is provided with vent.
A kind of speed reducer described in the utility model arranges slide block in the piston bottom, in pump barrel bottom vent is set, and utilizes the draught head of slide block in stroke up and down to reduce the load of pumping unit horsehead suspension point, and the simple and practical property of the utility model is strong.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Among the figure: the 1-pump barrel; The 2-slide block; The 3-piston.
Embodiment
Embodiment 1.
A kind of oil pump speed reducer described in the utility model, comprise oil pumping barrel 1 and slide block 2, pump barrel 1 inside is provided with the piston 3 that is slidingly connected with it, and slide block 2 is fixedly connected on the piston 3 by sucker rod, described piston 3 and slide block 2 all are arranged on pump barrel 1 inside, and the bottom of pump barrel 1 is provided with vent.
Load reducer for oil-pumping machine described in the utility model, slide block 2 upper and lower end faces are in respectively in the different pressure systems, when pumping unit horsehead is up, slide block 2 is under the effect of hydraulic feedback lifting force, sucker rod and piston 3 with movable slider 2 tops move upward together, thereby reach the purpose that alleviates the pumping unit horsehead suspending point loading; When pumping unit horsehead was descending, piston 3 promotes sucker rod and slide block 2 moves downward, and so finishes a stroke procedure.

Claims (1)
