Detailed description of the invention
In fig. 1 and 2, platen 2 is fixedly mounted on automobile chassis 1, and platen 2 is the most successively
Be installed with electromotor 3, change speed gear box 4, plunger displacement pump 6 and water tank, change speed gear box 4 by drive system 5 to
Plunger displacement pump 6 below transmits power, selects the electric-controlled mechanical change speed gear box 4 of band wriggling pattern, utilizes change speed gear box 4
With electromotor 3 slow fixation, separate, in conjunction with, then the characteristic separated, control defeated by pressure testing module 82
Go out voltage thus control clutch and combine ratio, transmission difference moment of torsion, thus remotely control realization automatic pressure testing merit
Energy.Local control system 8 is arranged on above plunger displacement pump 6, in addition to saving space, also can make operator
There is during work good visual angle, easy to operate.After suction manifold 7 and exhaust manifold 9 are arranged on chassis 1
Portion.Local control system 8 by holding wire respectively with electromotor 3, change speed gear box 4, tele-control system 11
Being connected, wherein, local control system 8 is by PLC 81, pressure testing module 82, gearbox gear-shift control
The local control system of molding block 83,84 and tele-control system handover module and 85 engine control module groups
Become.During cementing unit work, connect by technological process and fix each manifold, flow to beat open or close according to liquid
Closing respective valves, neutral gear hung by change speed gear box 4, and local control system 8 or tele-control system 11 control electromotor
3 open, during well cementing operation, and cut-off clutch, make change speed gear box 4 adjust by gearbox gear-shift control module 83
To required gear, change speed gear box 4 drives plunger displacement pump 6 to suck cement by suction manifold 7 by drive system 5
Slurry enters plunger displacement pump 6, injects well head finally by exhaust manifold 9.After injection completes, close electromotor 3,
Open each valve of self-loopa flow process, internal by clear water wash cycles clean plunger displacement pump 6 in water tank 10, prevent
Cement mortar blocks.When needing pressure testing operation, cut with tele-control system as desired by local control system
Control system is switched to local control system 8 or tele-control system 11 by die change block 84, operates electromotor control
