6 start-up and shut-down control.The ball valve 1 is arranged between gear-box 11 and temperature sensor 2, and wherein ball valve 1 is installed on the pipeline, energy
Oil liquid outflow in effective control gear-box 11.
The temperature sensor 2 is connected by pipeline with oil absorption filter 3, and the oil absorption filter 3 is by pipeline and admittedly
Body granule detecting instrument 5 is connected, and the quantity of solid particulate matter and the distribution situation of particle in energy real-time monitoring oil liquid are oil liquid product
The height and replacing construction of matter provide data reference, avoid the damage of electric-motor pump 6.
The setting of electric-motor pump 6 is between solid particle degree detector 5 and strong magnetic solid particle filter 7, the electric-motor pump 6
Including motor and oil pump, wherein motor can be directly connected to oil pump or be connected by bell jar with shaft coupling, electronic
Machine can be 4 grades, 6 grades or 8 grades, and oil pump is delivery pump, which can be suitable for the more medium of particulate matter.
Between the oil absorption filter 3 and solid particle degree detector 5, strong magnetic solid particle filter 7 and flow sensing
Survey pressure sample connection 4 is equipped between device 9 can connect pressure sensor 8 here in system operation to read relevant pressure
Data, the pressure difference value of two positions are able to reflect out oil liquid by solid particle degree detector 5, electric-motor pump 6 and strong magnetic solid
The pressure value lost after particulate filter 7, by the pressure difference value in the case of different temperatures, different flow and different pressures, from
And the flooding nozzle 10 of corresponding electric-motor pump 6 and corresponding construction is selected as needed, to guarantee that flooding nozzle 10 reaches due
Effect.The sampling that sampling hose carries out oil liquid can also be connected by surveying pressure sample connection 4, by extracting strong magnetic solid particle filter 7
The oil liquid sample of front and back is compared, it is known that oil product situation of the oil liquid after too strong magnetic solid particle filter 7.
The solid particle degree detector 5 is connected by pipeline with strong magnetic solid particle filter 7, wherein strong magnetic solid
Strong magnetic filtering core and dirt blocking signalling generator are respectively equipped in grain filter 7, when on the strong magnetic filtering core of strong magnetic solid particle filter 7
The solid particle of interception reaches a certain level when needing replacing, and signalling generator can sound an alarm prompt replacement filter core.
The strong magnetic solid particle filter 7 is connected by pipeline with flow sensor 9, and the flow sensor 9 passes through
Pipeline is connected with flooding nozzle 10, for monitoring traffic conditions when system work, can judge that system is according to the numerical value of flow
No failure.Especially in prototype test, according to the working effect of the size of flow and flooding nozzle 10, consider further that whether
It needs to adjust the revolving speed of motor or changes the structure of nozzle.
The flooding nozzle 10 is mounted on 11 inside of gear-box, and the lubricant effect of gear can be improved to face of gear oil spout,
The impurity such as remaining solid particulate matter on gear chamber interior wall can be rinsed simultaneously.
It is of the invention use process is as follows: operator is first turned on ball valve 1, and oil liquid passes through after the outflow of ball valve 1 in gear-box
Excess temperature sensor 2, temperature sensor 2 is by the temperature of monitoring oil liquid to determine whether the motor met in electric-motor pump 6 opens
Dynamic condition, when oil temperature reaches motor start-up condition, motor start-up, then oil liquid flows to oil absorption filter 3, at this time oil liquid

Strong magnetic solid particle filter 7 is flowed to after crossing electric-motor pump 6, and the solid particle of the overwhelming majority in oil liquid is filtered, it is special
It is not the particulate matters such as metal iron filings, aluminium skimmings in oil liquid, when the dirt that strong magnetic solid particle filter 7 intercepts reaches a certain amount of
Afterwards, the dirt blocking signalling generator above strong magnetic solid particle filter 7 can issue alarm signal, prompt replacement filter core and clear up strong
Magnetic filter core, subsequent oil liquid flow to pressure sensor 8 and flow sensor 9, if illustrating some portion of system when system pressure is too low
Position needs to check there are problem, while too low system pressure also makes the effect of flooding nozzle 10 reduce or lose accordingly
Effect, and flow sensor 9 can in monitoring system oil liquid flow, the flow system flow of normal work fluctuates within a certain range,
When flow occurs reducing more obvious, judge whether system leaks by checking the state of other sensors.Finally
After filtered cleansing oil liquid stream to flooding nozzle 10, oil liquid is sprayed to gear teeth face, bearing and cabinet wall by flooding nozzle 10
Be not easy the place being cleaned, be conducive to improve gear lubrication and with heat corresponding on bearing running, to avoid because of high temperature
It damages.
Respective sensor, the data of instrument can be used as replacement or the reference frame of maintenance system to this system at runtime:
When the temperature value that temperature sensor 2 monitors is normal, and the flow value that flow sensor 9 monitors is relatively low and strong magnetic solid
Dirt blocking signalling generator above grain filter 7 is not alarmed, and oil absorption filter 3 carries out cleaning replacement filter core at this time.
When solid particle degree detector 5 is shown in oil liquid for a long time there are more solid particle, and flow sensor 9 monitors
To flow value is relatively low and strong magnetic solid particle filter 7 above dirt blocking signalling generator do not alarm, need to examine at this time
Whether the dirt blocking signalling generator looked into above strong magnetic solid particle filter 7 damages, and replaces strong magnetic filtering core in time, then supervised
It surveys.
When the pressure value that pressure sensor 8 monitors is relatively low, and the flow value that flow sensor 9 monitors is normal, say
Bright flooding nozzle 10 goes wrong, and oil liquid does not reach corresponding injection, flushing effect, needs to check nozzle situation.
When the pressure value that pressure sensor 8 monitors is relatively low, and the flow value that flow sensor 9 monitors is also relatively low,
Illustrate that some position of system has leakage, needs to check.
Other undeclared parts of the present invention are same as the prior art.
