Description
Technical field
This utility model belongs to oil field compression fracture car hydraulic device maintenance tool technical field, relates to fracturing unit truck fluid end Y type pump low
Pressure valve seat takes out instrument.
Background technology
Pressure break is the unconventional petroleum resources exploitation core skills such as the volume increase of a kind of conventional oil gas field and shale gas, shale oil, coal bed gas
Art.Oil field compression fracture car is the capital equipment of pressing crack construction, belongs to oil-gas field drill special vehicle equipment.Main Function is to Oil/gas Well
Interior injection high pressure, the fracturing fluid of huge discharge, by being pressed off on stratum to stratum pump liquid injection pressure, clamp-on crack proppant, improves
Oil-gas Layer permeability and oil, gas well recovery ratio.Oil gas field site operation is the highest to fracturing unit truck technical property requirements, and fracturing unit truck must tool
There are the features such as pressure is high, discharge capacity is big, corrosion-resistant, abrasion resistance is strong.General oil field compression fracture car many with complete set of equipments set pressure break
Unit form occur, pressure break pump truck is pressing crack construction unit nucleus equipment, mainly by electromotor, hydraulic transmission box, fracturing pump,
Control system and other adnexaes form.The power size of pressure break pump truck directly reflects the ability to work of a whole set of unit, the elder generation of its equipment
The property entered is mainly reflected in power configuration, fracturing pump performance and control system.
Fracturing pump is the vitals of oil field compression fracture car, but its fluid end clack box often initial failure.Import YWS fluid end
High-low pressure valve and valve seat be better than domestic main flow CWS fluid end service life in extensive hydraulic fracturing process, thus
Greatly reduce the inspection pump frequency of maintenance in fracturing process.But owing to YWS fluid end structure is special, conventional CWS low pressure
It is the most applicable that valve seat takes out instrument, and the import used at present is taken out instrument and coordinated the tightest when manual operations with low pressure valve seat
Close, simultaneously because low pressure valve seat need to take out from high-pressure side, further increase valve seat and take out difficulty.In the urgent need to one pressure
Split car fluid end Y type pump low pressure valve seat and take out instrument, to meet YWS fluid end operation maintenance needs.
Utility model content
The purpose of this utility model is to provide a kind of fracturing unit truck fluid end Y type pump low pressure valve seat and takes out instrument, low in dismounting and change
It is easier to take out during pressure valve seat, reduces labor strength, improve work efficiency.The purpose of this utility model is by following
Technical scheme realizes.
Fracturing unit truck fluid end Y type pump low pressure valve seat takes out instrument, including the step surface on body, body and the hands on step surface
Dynamic traction apparatus, it is characterised in that described step surface is divided into one-level step surface and two stage steps face.
Further, the diameter of the described one-level step surface internal diameter more than low pressure valve seat and the external diameter less than low pressure valve seat, institute
State the diameter external diameter more than low pressure valve seat in two stage steps face.
Further, described hand traction device is piercing one's ears and by the drawing rope pierced one's ears on one-level step surface.
Further, described body is cylinder.
Further, described body is round platform, and the upper surface of round platform is one-level step surface, and the lower surface of round platform is two stage steps face.
Drawing rope is by having pierced one's ears hand traction effect, and one-level step surface directly contacts with low pressure valve seat, while interference fit
Ensure without departing from low pressure valve seat external diameter thus avoid and fluid end low pressure chamber body contacts.One-level step surface passes through body and two
Level step surface forms an entirety, and body can be cylinder or round platform.By design two-stage step surface, hammering or hydraulic pressure thousand
Push up two stage steps face on jin and make one-level step surface uniformly upper top low pressure valve seat, make low pressure valve seat uniform stressed.
The fracturing unit truck fluid end Y type pump low pressure valve seat that this utility model provides takes out tool operation conveniently, safely, effectively reduces
To the pump housing and the injury of valve seat when taking out low pressure valve seat, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is that the low pressure valve seat of embodiment 1 takes out instrument schematic diagram.
Fig. 2 is fluid end Y type pump schematic diagram.
Reference: 1-drawing rope, 2-low pressure valve seat, 3-pierces one's ears, 4-one-level step surface, 5-body, 6-two stage steps face,
7-plunger, 8-high pressure valve seat, 9-high pressure valve, 10-low pressure valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, fracturing unit truck fluid end Y type pump low pressure valve seat of the present utility model is taken out instrument to be described further.
It is used for taking out low pressure valve as it is shown in figure 1, fracturing unit truck fluid end Y type pump low pressure valve seat of the present utility model takes out instrument
Seat 2, including drawing rope 1, pierce one's ears 3, one-level step surface 4, body 5, two stage steps face 6.As in figure 2 it is shown, be different from
The cross fluid end of CWS, need to first take out high pressure valve body 9 and high pressure valve seat 8, low pressure valve during the maintenance of fluid end Y type pump
10 are first taken out by high-pressure side, use this instrument to be taken out by low pressure valve seat 2 afterwards.When taking out low pressure valve seat, drawing rope rises and leads
One-level step surface 4 is also in close contact by the effect of drawing with low pressure valve seat 2.The diameter of one-level step surface 4 is more than low pressure valve seat 2
Internal diameter and less than the external diameter of low pressure valve seat 2 so that one-level step surface 4 and low pressure valve seat 2 contact surface retain certain laterally
Distance, thus ensure that one-level step surface 4 is contactless with fluid end low pressure chamber body.The diameter in two stage steps face is more than low pressure valve
The external diameter of seat, can use hydraulic jack or percussion hammer to press to two stage steps face 6, thus be taken by low pressure valve seat smoothly
Go out.This taking-up tool construction is simple and reliable, easy to use, safe, efficiently solves fracturing unit truck fluid end Y type pump low pressure valve
Seat takes out difficult problem.
