Description
Technical field
The present invention relates to a kind of testing stand hydraulic station electric hydraulic system, suitable for machinery field.
Background technology
Hydraulic station is component assembly important in hydraulic system, and the good and bad performance on hydraulic test of designing quality influences
It is very big.Hydraulic station generally comprises hydraulic station and hydraulic power unit two large divisions, and in many hydraulic systems, the two usually integrates
(or place) together.
Hydraulic Elements multi-function test stand can carry out functional test and performance checking to all kinds of Hydraulic Elements, generally mostly using collection
Middle fuel system, hydraulic station can provide hydraulic oil for hydraulic pump test stand, and hydraulic oil is provided for other test stand for hydraulic element
Source.
The content of the invention
The present invention proposes a kind of testing stand hydraulic station electric hydraulic system, by 3 pump group, fuel tank, cooling device parts
Composition, fuel tank, pump group are highly convenient for expanding and be adjusted, can also be shortened the design cycle using separated structure.
The technical solution adopted in the present invention is：
The testing stand hydraulic station hydraulic system is made of 3 pump group, fuel tank, cooling device parts.
The pump group is by 1#Pump, 2#Pump, 3#Pump and drive motor composition each pump each own individual pressure and adjust control
Unit block (electromagnetic relief valve etc.) processed and hydraulic oil filter, are respectively intended to regulating system safe pressure and safeguard work fluid
Cleannes.
The fuel tank is open architecture, and auxiliary has 2 filters, the convertible liquid level gauge of magnetic, temperature transmitter, 4 heating
Device.
The cooling back installation is by groups such as water-cooled cooler, circulating pump, filter, thermometer, pressure gauge, check valves
Into.
The electric control system is directly controlled using relay, and hydraulic station is controlled using two places, selects to grasp by observing and controlling cabinet
Make.
The beneficial effects of the invention are as follows：The electric control system the operation is stable, hydraulic station are with good expansibility,
Slightly adjustment can be that other equipment (such as hydraulic press) provides hydraulic energy source.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, small plunger pump 16, big plunger pump 29, vane pump 34 are fuel-displaced respectively by pressure piping filter 13 11,
13-2,13-3 are filtered, and are set up out oil pressure by electromagnetic relief valve 10,24-1,24-2 respectively and are played protection function.Main confession
Flow P mouthfuls oily controls small plunger pump 16, big plunger pump 29,34 groups of vane pump respectively by electromagnetic relief valve 10,24-1,24-2
It closes and realizes.Circulating cooling filtration system 41 is by motor 1, gear pump 3, filter 9 and cooler 8 and other related auxiliary groups
Into.Return filter 38 is filtered system oil return.Filter has differential pressure signaling device, when plugged filter sends alarm
When, closing system replaces filter core in time.Fuel tank provides for producer, and hydraulic station uses separated structure.The hydraulic station has good
Scalability, slightly adjustment can be other equipment (such as hydraulic press) provide hydraulic energy source.
The design of integrated package is the important content of design of Hydraulic System, from all medellings of design, material, technique.It is three-dimensional
Intersect utilization with two-dimensional graphics software, can make the design process more directly perceived, can prevent hole system from interfering, improve work efficiency.It is three-dimensional
Mapping software may be also used in structural member and stringing design.
Xun Huan pump motor directly initiates, and in terms of the larger motor start-up of other power, electrical measure is dropped for Y- △
Pressure starts, and hydraulic system is started using off-load, to ensure that system is safe and reliable, prevents unexpected generation.Using air switch QS1-
QSS is as point electricity of motor and protection device.When hydraulic station designs, various factors is considered, to reduce fluid pressure line
With the distance of conducting wire.
Electric control system of hydraulic station points are less, control, generally to be protected by intermediate relay defeated according to PLC
Go out a little, therefore, which is directly controlled using relay.Hydraulic station is controlled using two places：Local control (1#Power control cabinet), far
It controls (Central Control Room observing and controlling cabinet), by observing and controlling cabinet selection operation.Central Control Room and pumping plant switch board are designed with scram button.
Comprehensive preparation is carried out before system design, installation and debugging, formulates complete plan and safety regulation for operations, with
It shortens the construction period.
In debugging, motor dust cover can be removed, without dismounting couplers, row carries out motor again after dish pumping oil suction
Start-up and Adjustment.Start for the Y of motor and △ starts direction and conscientiously to record, adjust in due course, prevent that directly carrying out Y- △ opens
It is dynamic that accident occurs.
Every electric function debugging finishes, you can the system of progress beats circulation flushing.In one oil return line circulation flushing of pressure oil
When, find a failure symptom：Circulation line is not warm, flows sign, leakage line extreme heat without fluid.It is sent out by investigating
Existing, the plate-type non-return valve 12 being mounted on integrated package is anti-loaded, causes the direct overflow oil return box of pressure oil.As it can be seen that processing
The equipment of manufacture, which is conscientiously checked, to be also very important.Otherwise, installation and debugging process can more or less be influenced.
