A kind of double-core super-pressure pump of the spare booster of band
Technical field
The invention belongs to high pressure water jet high-pressure water cutting field more particularly to a kind of pairs of the spare booster of band
Core super-pressure pump is a kind of extremely-high tension generator device that can complete online automatic switchover free of discontinuities.
Background technology
Currently, extremely-high tension generator product is generally single pressurizator in the market, i.e., an increasing is only used in whole system
Depressor is made of motor and hydraulic pressure pump group, hydraulicdirectional control valve, separate unit booster, accumulator and electric-control system and rack, is substantially
Most common extremely-high tension generator type in high-pressure water cutting machine, has the characteristics that small, price is low.Super-pressure occurs
Booster in device product is core component, but for various reasons, booster often has pressure, internal leakage, plunger disconnected
It the failures such as splits to occur so that shutdown maintenance must be carried out, cause process to interrupt, influence production efficiency, and influence to cut
Quality.
Invention content
Production disruption phenomenon caused by order to solve existing extremely-high tension generator booster failure, ensures the company of process
Continuous property, provides a kind of double-core super-pressure pump of the spare booster of band, while restarting process again after preventing work pieces process from interrupting
The seam phenomenon of section generation causes the case where useless part.
The technical solution adopted is that:
A kind of double-core super-pressure pump of the spare booster of band, including the first booster, the second booster, the first hydraulic control valve,
Second hydraulic control valve, hydraulic switching valve and Lode switching valve.
Technical points are.
A mouth the first hydraulic control valves of piping connection one end of hydraulic switching valve, the other end pipeline of the first hydraulic control valve
Connect the hydraulic port of the first booster.
The A mouths of the water outlet line connection Lode switching valve of first booster, the export pipeline connection of Lode switching valve store
The entrance of energy device.
One end of B mouth the second hydraulic control valves of piping connection of hydraulic switching valve, another end pipe of the second hydraulic control valve
Road connects the hydraulic port of the second booster.
The B mouths of the water outlet line connection Lode switching valve of second booster.
It the advantage is that:
For this super-pressure pump when a booster breaks down, system can perform handover to another under non-stop-machine state
Booster ensures equipment continuous operation, requires the high part for not allowing interruption to have important guarantee especially for processing quality,
It increases economic efficiency.The seam phenomenon of process section generation is restarted after preventing work pieces process from interrupting simultaneously again, causes useless part
The case where.
It is arranged in parallel the identical booster of two model specifications in one super-pressure pump system, one work is another when work
For spare, when breaking down for wherein one can be switched to another booster works platform.It is when switching booster
Using 2 kinds of switching valves switching is realized by the operation program set.When being switched to another booster and being worked, occur therefore
The hydraulic pressure road of the booster of barrier and water route are disconnected with work system, can carry out on-line maintenance or direct dismounting and change, superelevation
Press pump is not required to shut down.

Specific implementation mode
A kind of double-core super-pressure pump of the spare booster of band, including the first booster 4(Booster A), the second booster 9
(Booster B), the first hydraulic control valve 3, the second hydraulic control valve 8, hydraulic switching valve 2 and Lode switching valve 5.
3 one end of the first hydraulic control valve of A mouth piping connections of hydraulic switching valve 2, another end pipe of the first hydraulic control valve 3
Road connects the hydraulic port of the first booster 4.
The A mouths of the water outlet line connection Lode switching valve 5 of first booster 4, the export pipeline connection of Lode switching valve 5
The entrance of accumulator 6.
One end of the second hydraulic control valve of B mouth piping connections 8 of hydraulic switching valve 2, the other end of the second hydraulic control valve 8
The hydraulic port of the second booster of piping connection 9.
The B mouths of the water outlet line connection Lode switching valve 5 of second booster 9.
The entrance of the outlet connection nozzle assembly 7 of accumulator 6.
The signaling interface of hydraulic switching valve 2 and the signaling interface of Lode switching valve 5 are correspondingly connected with electric-control system 11 respectively.
The signaling interface of the signaling interface of first booster 4 and the second booster 9 is correspondingly connected with fault monitoring device 10.Electric-control system
11 are correspondingly connected with fault monitoring device 10
The entrance of 1 piping connection hydraulic switching valve 2 of hydraulic power supply provides hydraulic-driven power by hydraulic power supply 1 in Fig. 1,
Pressure oil is connected through the selection of hydraulic switching valve 2 with A branches(Or B branches), pass through the first hydraulic control valve 3(Or the second hydraulic pressure control
Valve 8 processed)Control the first booster 4(Or second booster 9)Commutation work simultaneously pressurizes water, while Lode switching valve 5 and A
Branch(Or B branches)It connects, the high-pressure water through being overpressurized enters accumulator 6 via Lode switching valve 5, finally by nozzle sets
Part 7 ejects, and is processed to workpiece.10 the first booster of on-line real time monitoring 4 of fault monitoring device(Or second booster 9)
Working condition and data are sent to electric-control system 11, when monitor break down by influence work normally when, electric-control system 11
Action command is sent out, hydraulic switching valve 2 and Lode switching valve 5 act simultaneously at this time, rapidly by pressure oil and B branches(Or A branch
Road)Connect and with A branches(Or B branches)It disconnects, by B branches(Or A branches)High-pressure water be connected to accumulator 6, and will
Branch A(Or B)High-pressure water and accumulator 6 disconnect, and then realize the real-time switching between spare booster, this high-pressure pump
It can carry out non-stop run.The working condition of booster is monitored using fault monitoring device 10, and is carried out by electric-control system 11
It automatically controls.
It is " double-core " that the identical booster of 2 specifications parameters is arranged in a whole set of super-pressure pump system.2 boosters are being
Be arranged in parallel in system, be respectively set hydraulic switching valve door and super-pressure waterway switching valve before and after booster, switch valve by
Electric-control system completion automatically controls.When electric-control system detects that wherein a booster breaks down, hydraulic pressure road valve and water
Road valve acts simultaneously, and hydraulic pressure road and water route are switched to another booster simultaneously, simultaneously turn off failure intensifier hydraulic road
With water route, make system that can continue to work under setup parameter in the case that non-stop-machine.Simultaneously for faulty booster
On-line maintenance or replacement can be carried out, system is restored to double turbocharger conditions again after the completion of repair, remains a booster
In stand-by state.
