The utility model has the advantages that control precision is high, reliability is strong, and the high-speed centrifuge is in full frequency conversion and full automatic control.
Description
Technical field
The utility model relates to a kind of petroleum drilling fluid Based Intelligent Control supercentrifuge that is applicable to.
Background technology
At present, petroleum drilling fluid is not high and invariablenes turning speed with the most rotating speed of centrifuge, can not regulate operational factor automatically according to actual conditions, and there is following problem in this mode:
1,, can not satisfy in the existing borer drilling procedure requirement to drilling fluid because centrifuge speed is not high, and its separation mid point is too big.
2, because centrifuge speed is fixed, can not adapt in different stratum, the different drilling process, promptly use scope narrower, can not reach best treatment effect the requirement of property of drilling fluid.
3, because the solution feed pump rotating speed is fixed, when the property of drilling fluid parameter changes,, often make the centrifuge blockage phenomenon because the solid phase that produces is more.
4, because the working environment of centrifuge is general relatively more abominable, original Centrifugal Machine Control System overload protection arrangement can not play the reliable protection effect.
Summary of the invention
The utility model is for solving the on-the-spot drilling fluid that uses with the above-mentioned technical problem that exists in the centrifuge, adopt centrifuge speed and the VFC mode of improving, strengthen the centrifuge performance, the purpose of this utility model provides a kind of drilling fluid supercentrifuge for the scene exactly.
Technical solution of the present utility model is: the utility model comprises slurry supply pump, centrifugal basket, differential mechanism, conveyer, main motor, it is characterized in that: main motor 3 is circumscribed with console controller 1, slurry supply pump 8 is connected to slurry supply pump controller 2, and slurry supply pump controller 2 is circumscribed with torque sensor 9.
Above-mentioned console controller 1 is frequency-variable controller, single-chip microcomputer, computer.
Above-mentioned slurry supply pump controller 2 is frequency-variable controller, single-chip microcomputer, computer.
Above-mentioned torque sensor 9 other ends are connected to safety pin 6.
Above-mentioned safety pin 6 other ends link to each other with differential mechanism 5.
The utlity model has following advantage:
1, centrifuge speed height of the present utility model, its separation mid point is little, can satisfy in the existing borer drilling procedure requirement to drilling fluid.
2, the utility model main frame adopts VFC, applied widelyly can carry out frequency control to Different Strata, different drilling process according to the actual conditions of drilling technology, thereby obtains best treatment effect.
3, the utility model slurry supply pump adopts VFC, has the ability that adapts to different property of drilling fluid, realized intelligent frequency-conversion control, when drilling liquid parameter changes, the pump machine controller can be regulated the centrifuge operational factor automatically by the information of sensor feedback, automatically regulate the discharge capacity of slurry supply pump, avoided the clogging of centrifuge.
4, the utility model adopts complete explosion-proof control, and overload protection can play the reliable protection effect.
