Description
Technical field
The present invention relates to a kind of slurry pump control technique, particularly a kind of slurry pump control system.
Background technique
Slurry pump is in the drilling process, the machinery of washing solutions such as slurry conveyed or water in boring.Slurry pump is the important component part of drilling equipment, in direct circulation probing commonly used, it is with face of land flushing medium--clear water, mud or polymer flush fluid are under certain pressure, through the bottom of cylinder sleeve, water tap and drill string center hole direct sending drill bit, to reach the cooling drill bit, the landwaste that cuts to be removed and is transported to the purpose on the face of land.Slurry pump commonly used is piston type or plunger type, and the bent axle Hui Zhuan ﹐ bent axle that drives pump by power engine drives piston again by crosshead or plunger moves reciprocatingly in pumping cylinder.﹐ realizes the purpose of force feed and circulation flushing liquid Xia the alternating action of suction and expulsion valve.
The present slurry pump that uses, it needs according to actual needs in the process of using, and different pump pressures is provided.Since different cylinder sleeve the pressure that can bear be different, therefore when needs provide different pump pressure, need with changing cylinder sleeve, the power of adjusting power engine simultaneously and being provided, to satisfy required pump pressure, change cylinder sleeve continually and regulate power engine, make that on the one hand operation is various, working efficiency is low, makes that on the other hand the cooperation between the cylinder sleeve is not tight because of repeatedly dismantling.Generally speaking, slurry pump is to adopt petrol engine or power engine equal power device as power, impeller is rotated and is made slurry pump carry out work, adopt the slurry pump of such transmission device,, adopt air tank control pump pressure mainly by the pressure in the control of the air tank on the slurry pump cylinder sleeve, pressure surge in the cylinder sleeve is big, and required cylinder sleeve progression is many, changes the cylinder sleeve complex operation, inefficiency.More advanced slurry pump, what its power adopted is variable-frequency motor, by driving mechanisms such as belt pulleys, transmission of power to cylinder pump is driven the slurry pump operation by variable-frequency motor.Owing in transmission of power, adopted transmission devices such as belt pulley, pass through transmission device on the one hand, make slurry pump delay of response, can't promptly control, adopt the belt pulley transmission on the other hand, belt skids easily, can't accurately control the pump pressure in the cylinder sleeve, can not reduce the progression of required cylinder sleeve effectively.
Summary of the invention
Goal of the invention of the present invention is: at the problem of above-mentioned existence, provide a kind of simple in structure, easy and simple to handle, cylinder sleeve progression is few, with low cost, the slurry pump control system being convenient to safeguard, can monitor pump pressure quickly and effectively and report to the police and handling, this slurry pump control system, pressure surge is little, and the slurry pump life-span is long.
The technical solution used in the present invention is as follows:
Slurry pump control system of the present invention, comprise slurry pump and cylinder sleeve, described cylinder sleeve is connected on the slurry pump, this control system also comprises HMI, PLC, frequency variator and pressure transducer, described HMI is connected with PLC, described PLC is connected with frequency variator, and described frequency variator is connected with slurry pump, and described pressure transducer is arranged in the cylinder sleeve and is connected on the PLC.
Owing to adopted said structure, formed a complete control system.Because this control system is the result who merges design with electromechanics, does not have other driven accessaries such as belt pulley, make the torque of pump pressure and motor form a very simple unary linear relation.When specific operation; the operator is required work pump pressure value of input and cylinder sleeve diameter on HMI at first; the IMF pump pressure value of will working is passed on the PLC; the PLC control system calculates the work pump pressure automatically; the corresponding relation of cylinder sleeve and Motor torque; PLC is passed to control signal on the frequency variator then; thereby the control frequency variator is to what of the power supply of slurry pump; the moment of torsion of control slurry pump; described slurry pump is connected to form by motor and pumping cylinder; needed moment of torsion when motor can only the output services pump pressure; when the power that power that produces when pump pressure and Motor torque produce reaches balance; motor can not provide the moment of torsion that is higher than the work pump pressure again, and controlling pump pressure does not exactly transfinite, thereby the working procedure of whole fluid end is carried out real-time safety protection; avoid the generation of security incident effectively, and be convenient to operation.Owing in cylinder sleeve, be provided with pressure transducer, and utilize standpipe pressure as pressure feedback, compare with the work standpipe pressure, as run into pressure anomaly, pressure transducer is passed to signal on the PLC control system, control system is made rapid reaction and is reduced pump and dash or propose to report to the police etc., and the warning upper lower limit value can be provided with on HMI by hand and also generate automatically according to unary linear relation in the program by PLC.Generally speaking, the cycle period of PLC can be controlled in the 100ms, receives that the signal post-processing device can make instruction timely, avoids accident to take place.Owing to adopted above-mentioned technology, only need to select the cylinder sleeve of big progression to get final product, can accomplish
5000psiPressure is with the interior cylinder sleeve that do not change, so can ignore the factor of cylinder sleeve in very wide pressure range, considers that if desired the cylinder sleeve factor then directly selects the cylinder sleeve model to get final product on HMI.Owing to adopted above-mentioned technology, reduce required cylinder sleeve widely, thereby reduced cost, reduced the time of changing cylinder sleeve, improved working efficiency.
Slurry pump control system of the present invention, described slurry pump are the directly driving type slurry pump.
Owing to adopted said structure, slurry pump is the directly driving type slurry pump, is convenient to control the rotating speed of slurry pump, and starts steadily, does not have and impacts, and it is smooth-going to work.
Slurry pump control system of the present invention, described slurry pump are directly driving type five cylinder slurry pump.
Because to have adopted said structure, slurry pump is directly driving type five cylinder slurry pump, make slurry pump can not produce instantaneous high pressure in the course of the work, stable working, and be more conducive to the control of slurry pump rotating speed.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows:
1, slurry pump control system of the present invention, simple in structure, simple operation, with low cost;
2, slurry pump control system of the present invention, the power transmitting deice of no medium tache, the direct controlling and driving motor can accurately be controlled slurry pump, is swift in response;
3, slurry pump control system of the present invention adopts Electromechanical Design, thereby the working procedure of fluid end of pump is carried out real-time safety protection, has avoided the generation of security incident effectively;
4, slurry pump control system of the present invention, required cylinder sleeve progression is few, is convenient to maintenance, has saved cost widely, and less cylinder sleeve is changed the time, has improved efficient;
5, slurry pump control system of the present invention can not produce instantaneous high pressure in the working procedure, and pressure surge is little, and little to the vibrations of slurry pump, the life-span is long, reduces cost.
