Description

A kind of horizontal oil pumper of double-steel wire rope

Technical field

This utility model belongs to oil exploitation field of mechanical technique, is specifically related to a kind of horizontal oil pumper of double-steel wire rope.

Background technology

Existing oil pumper passes through mobile under belt slides on cylinder thus drives pumping rod oil pumping, and it is stable Property good, but stroke is short, energy consumption is big, owing to belt and cylinder contact area are big, thus frictional force is big, and energy consumption is high, hot When working under environment, the easy aging deformation of belt, when working in the environment of cold, belt easily ossifys, at the ring that dust storm is bigger When working under border, can join and have sand, belt slip to be obstructed between belt and cylinder, in general, belt is short for service life, is suitable for Scope is little.Some oil pumpers use roller structure, work, often break down in the environment of dust storm is bigger, and roller needs Artificial the most oily, operation bothers very much.

In oil exploitation use oil pumper be mainly beam pumping unit, it mainly by base, motor, reductor, Crank, connecting rod, walking beam, caput Equi Asini, belt form, oil pumper all be use a motor as power, power of motor be 37 or 45kw, owing to needing power bigger when oil pumper starts, when oil pumper normally works after starting, under the inertia of balancing weight, Required drive is smaller, and uses the motor of 37 or 45kw to cause energy waste.

Speed reducer base on existing oil pumper is connected by welding manner with base, due to the existence of welding stress, Making the yielding tilting in base two ends, floor installation is insecure, and during the work of such oil pumper, base easily rocks and causes safety hidden Suffer from.
