Object of the present invention be exactly a kind of reliability to conventional oil slurry pump of drilling machine will be provided, method that real-time carries out intelligent test.The employing of the method, make operator's energy one key realize the test of slurry pump, and next important cargo handling operation can be entered fast, make seamless link between two cargo handling operations, eliminate traditional method potential risks, and simple to operate, test result is not affected by human factors.
The present invention is achieved through the following technical solutions:
1, oil-well rig slurry pump controlling method, the method step is as follows:
1) slurry pump intelligent test function is started: the startup being realized test function by two soft negate buttons of human-computer interaction device;
2) slurry pump is determined whether in operation: programmable controller judges the enable signal of current all slurry pump, and the slurry pump without enable signal is defined as non-slurry pump to be measured;
3) pump punching be zero: programmable controller judges the pump stroke signal of current all slurry pump, pump stroke signal be zero slurry pump be defined as non-slurry pump to be measured;
4) slurry pump to be measured is determined: rushing with or without slurry pump pump in operation and step 3 in programmable controller combining step 2 is after zero, has enable signal and pump to rush non-vanishing slurry pump and is then confirmed as slurry pump to be measured;
5) store slurry pump to be measured when front pump punching value: programmable controller store respectively slurry pump to be measured when front pump punching value, judge whether slurry pump to be measured restores to the original state the standard of state as follow-up;
6) pump rushes setting value clearing: the pump of all slurry pump to be measured is rushed setting value and resets by programmable controller, and maintenance motor is in zero velocity state by the output of frequency variator, and slurry pump remains static;
7) timing: the pump punching that programmable controller monitors slurry pump to be measured is all start timing after zero;
8) timing time increases given to every platform slurry pump to be measured after terminating: the time of programmable controller set by two kinds of patterns judges timing time, if timing time does not reach the time of setting, then continue timing, if timing time arrives, then enter next step pump to be measured and rush setting value increase by 1 punching;
9) No. X pump to be measured rushes setting value increases by 1 punching: slurry pump pump to be measured for every platform is rushed setting value by programmable controller increases by 1 punching, detects actual pump punching value simultaneously;
10) punching of X pump recovers: the pump punching value of this pump when programmable controller judges that the current actual pump punching value of every platform slurry pump to be measured and test function start, if No. X pump pump punching value to be measured does not reach the pump punching value of this pump when test function starts, then turn back to No. X pump to be measured and rush setting value increase by 1 punching, until the pump punching value before reaching test, if the slurry pump reaching the front pump punching of test runs by this state;
11) whole pump to be measured recovers: programmable controller judges the pump punching value that every platform slurry pump to be measured is respective before whether front pump punching reaches test, when state before system judges the startup test function that whole slurry pump recovers, system just can enter next step reset test function;
12) reset test function: programmable controller monitors when test function is known clearly in the state before system judges the startup test function that whole slurry pump recovers or user's cancellation, programable controller system meeting reset test function, controls slurry pump to be measured and runs according to running state during reset test function;
13) test report is provided: after proper testing terminates, programable controller system can provide test report, comprise the important parameters such as test is consuming time, reliability, dynamic characteristic, treatment advice, if improper end test function, programable controller system can point out the warning prompt tested and failed;
14) terminate: any mode terminates test function, programable controller system all can make slurry pump to be measured then run according to running state during reset test function;
15) sound a warning: if be that system can propose corresponding warning by human-computer interaction device in operating condition in enabled state or without any slurry pump without any slurry pump when starting slurry pump test function.
Wherein two kinds of test parameter pattern reciprocal interlockings, can only use a kind of pattern simultaneously.
Wherein two kinds of patterns all can be cancelled by operator at any time and interrupt in running, in the running state of slurry pump when can remain on interruption of having no progeny continue to run, enter normal operation mode.
Compared with prior art, beneficial effect of the present invention is:
The present invention is after a upper cargo handling operation terminates, only need on the touch screen of visual human-computer interaction device a key operation, after PLC receives instruction, the slurry pump setting value of current use can be made zero rapidly, judge whether the actual parameter of slurry pump meets the requirement stopped soon simultaneously, make corresponding information, the original running state that slurry pump can recover automatically after the time delay of setting, PLC can judge that can the actual parameter of slurry pump meet requirement that slurry pump rises soon and make corresponding prompting again, finally makes the report of slurry pump test.Operator just can realize the test of slurry pump soon, and can enter next important cargo handling operation fast, makes seamless link between two cargo handling operations, eliminates traditional method potential risks, and simple to operate, test result is not affected by human factors.
