Description
Technical field
This utility model is related to a kind of driving means, and in particular to one kind is surged safe valve drive, it is adaptable to oil
The application of mining site.
Background technology
At present, wide variety of on oilfield is that Mechanical Driven reciprocating pump, i.e. diesel engine or motor pass through belt
Gear reduction, and Jing after gear reduction unit slows down, then carried out by crank connecting link and guide runner drive piston rod and piston past
Multiple motion, realizes imbibition and discharge opeing.Because toggle determines that the movement velocity of piston is similar to sinusoidal variation
Rule, thus, the instantaneous delivery of reciprocating pump pumping cylinder is also to fluctuate by sinusoidal rule, in order to mitigate reciprocal pump main in stream
The fluctuation of amount and malleation, the generally outlet in pump is mounted with shock absorber for output, its drawback be not only increased equipment weight but also
Increased the difficulty of maintenance.Mechanical Driven reciprocating pump is adopted in addition, and stroke is short, high jig frequency, inertia big, serious vibration, machinery mill
Damage high, pump valve service life short.
Abroad, the application of hydraulic-driven reciprocating pump is more and more extensive, and using the increasing development trend of power.
In China, oilfield hydraulic reciprocating pump is still in the development stage, and relevant technical data extremely lacks, and wherein key technology is
The conversion of commutation control and high power hydraulic energy.
The content of the invention
The purpose of this utility model is：There is provided one kind to surge safe valve drive, its superiority is to eliminate routine
The toggle of reciprocating pump drives, and using Driven by Hydraulic Cylinder, it is easy to accomplish long stroke, low jig frequency, improves reciprocal pump work
Performance, with small in volume, life-span length, little without impact, inertia, it is easy to accomplish electrodeless variable-speed, automatically control and transship guarantor
Shield.
The technical scheme that the technical problems to be solved in the utility model is adopted is：The one kind is surged safe valve drive
Including indicating arm, hydraulic cylinder, plug, piston guide ring, piston, upper spring seat, valve rod adapter sleeve, spring, drive enclosure, tune
Whole pad, stem guiding ring, valve gap adapter sleeve, lower spring cup, base plate, gland, U-shaped filler, valve rod, valve gap, grease pouring valve,
Greasing hole nameplate, high pressure resistant O-ring seal, interior hexagonal flush end holding screw, O-ring seal, interior hexagonal tapered end holding screw, six
Angle screw and rivets for rame plate.
This utility model one kind is surged in safe valve drive, is installed valve gap and U-shaped filler in the bottom of valve rod and is filled out
Material gland.
This utility model one kind is surged in safe valve drive, installs stem guiding ring at the middle part of valve rod and valve gap connects
Female connector.
This utility model one kind is surged in safe valve drive, and lower spring cup and base plate are installed on the outside of valve gap adapter sleeve
And adjust pad is placed on valve gap adapter sleeve top.
This utility model one kind is surged in safe valve drive, and on the top of valve rod valve rod adapter sleeve is installed, and then will
Spring is placed on lower spring cup.
This utility model one kind is surged in safe valve drive, and upper spring seat is arranged on valve rod adapter sleeve.
This utility model one kind is surged in safe valve drive, with hex screw connecting bottom board and drive enclosure.
This utility model one kind is surged in safe valve drive, and on drive enclosure top, endoporus installs hydraulic cylinder portion
Part.
This utility model beneficial effect is：Long stroke, low jig frequency, improve reciprocating pump service behaviour, with small volume weight
Gently, life-span length, little without impact, inertia, it is easy to accomplish electrodeless variable-speed, automatically control and overload protection.
