Abstract
The invention relates to a technical of oil and natural gas drilling, in particular to a novel fracturing pump cross head device, which comprises a cross head, a copper sleeve connected with the cross head, and two pressing block fixed inside the cross head. Inside the cross head there designs through-holes for fixing the copper sleeve, which is composed of a left copper sleeve, a bearing shell and a right copper sleeve, and the pressing blocks are used for fixing the bearing shells. The installation of the invention consists of three parts. It's convenient to install, with high material-utilizing rate, good interchangeability and simple processing. The invention increases the forced surface of the copper sleeve and accordingly reduces the forced specific pressure, with high reliability. Lubricating oil come directly from the cross head into the copper sleeve to lubricated and cool down the latter with a better effect.
Description
Technical field
The present invention relates to petroleum and natural gas drilling technique field, particularly to a kind of new fracturing pump crosshead device.
Background technology
Fracturing pump is widely used in petroleum gas pressure break scene, and the large and small head of traditional pressure break pump rod 2 ' generally all adopts cunning
Dynamic bearing, crosshead pin 5 ' is fixed on crosshead 3 ' in the hole, and copper sheathing 4 ' is fixed on small end of connecting rod endoporus, small end of connecting rod and copper sheathing
It is assemblied on crosshead pin 5 ', opposing oscillatory between crosshead pin 5 ' and copper sheathing 4 ' during operating；Copper sheathing 4 ' and crosshead pin 5 ' it
Between lubricating oil be derived from big end, lubricating oil enters big end from the axle journal of bent axle 1 ', then passes through the oil duct in connecting rod
A ' enters small end of connecting rod.
The attachment structure of conventional linkage, crosshead, copper sheathing and crosshead pin is limited by crosshead and connecting rod monnolithic case knot
The restriction of structure size, copper sleeve inner hole size is little, and width pressure-bearing surface length is only small end of connecting rod width so that fracturing pump
In the course of work, copper sheathing stress is obvious bigger than big end than pressure, and reliability reduces.The lubricating oil of small end of connecting rod is derived from even simultaneously
Bar major part, lubricating oil oil mass is not enough, and lubricating oil is after big end sliding friction pair, and oil temperature has built up, therefore
, with respect to the sliding bearing of big end, the ratio pressure of its sliding bearing is bigger, lubricating oil fuel delivery for the sliding bearing of small end of connecting rod
Less, oil temperature is higher, and these unfavorable factors make small end of connecting rod sliding bearing become a weak spot of equipment, excellent to equipment
Change design totally unfavorable.
Content of the invention
It is an object of the invention to: a kind of structure novelty, reliable operation, easy accessibility, one kind of high working efficiency are provided
New fracturing pump crosshead device.
In order to achieve the above object, the invention provides following technical scheme.
A kind of new fracturing pump crosshead device is it is characterised in that include:
Crosshead, described crosshead offers big oil groove, oilhole one, oilhole two and oilhole three；
Copper sheathing, described copper sheathing is arranged in described crosshead, offers through hole and mate with described copper sheathing in described crosshead, described
Copper sheathing is made up of left copper sheathing, right copper sheathing and the bearing shell being located between described left copper sheathing and right copper sheathing, and described left copper sheathing offers
Oil groove one, described bearing shell offers oil groove two, described right copper sheathing offers oil groove three；
Briquetting, described briquetting is used for fixing described bearing shell, and the quantity of described briquetting is 2, is respectively used to the upper and lower of fixing bearing shell
Two sides, described briquetting offers n screwing through hole, and n is the positive integer more than or equal to 2, in the internal corresponding position of crosshead
Put and offer the screw hole mating with above-mentioned screwing through hole, screw passes through the screwing through hole on described briquetting to enter described crosshead
On screw hole described briquetting is pressed on described bearing shell, described bearing shell is fixed, prevents described bearing shell from rotating.
As the preferred version of the present invention, described oilhole one connects described big oil groove and described oil groove one, described oilhole two
Connect described big oil groove and described oil groove two, big oil groove and described oil groove three described in described oilhole tee joint, in described big oil groove
Oil directly described left copper sheathing, right copper sheathing and bearing shell are lubricated.
As the preferred version of the present invention, described left copper sheathing and right copper sheathing are arranged in described crosshead by interference fit
Both sides, prevent described left copper sheathing and right copper sheathing from rotating with respect to described crosshead, described bearing shell is fixed on by described briquetting
In described crosshead and positioned between described left copper sheathing and right copper sheathing.
Compared with prior art, beneficial effects of the present invention:
1st, copper sheathing is divided into three parts to be installed, easy for installation, and stock utilization is high, and interchangeability is good and processes more simply square
Just；
2nd, because the contact area increasing connecting rod small-end bearing and crosshead pin makes copper sheathing stress surface increase, thus stress subtracts than pressure
Little, the reliability of part is higher；
3rd, lubricating oil directly from crosshead enter copper sheathing copper sheathing is lubricated and lower the temperature so that lubricating oil to the cooling of copper sheathing and
Lubricant effect is more preferable.
