Research On The Design Of Pump Truck Carried On AMT

Thesis study for a400-type pump used in oil exploration in the high-pressure liquidinfusion process, and focuses on the engine and gearbox with the design process. Thispump truck due AMT gearbox includes a of12Draw step-shifting, and similar products aregenerally only mounted grades mechanical or hydraulic transmission of the sixth gear, andtherefore this pump truck for more precise flow control, also has nearly control and30meters from the control, automatic overpressure protection functions, handling and securityhave been improved.Oilfield cementing truck is a kind of pumping equipment, Which commonly used in theproduction of oilfield. It is used between the beginning of the oil well drilling to the end ofproduction cycle of the oil well. The basic function of cementing truck is cementingoperation. During this process the user attention operation parameters. Such as pressure,displacement and cement density. The parameters: displacement and pressure, interrelatedby the device itself. And closely related is the engine power, speed, transmission ratio,three cylinder pump power, pressure rating, plunger diameter.Cementing truck overcomes the formation pressure and the fluid pressure during theprocess of injection. Injection speed has strict requirements: too slow, solidification ofcement maybe happen before the end of injection process. Too fast, oil well is unable towithstand the pressure inside the well, and the pipe in the well maybe damaged. These twoconditions are not conducive to cementing operation. The traditional device using a third orsix speed gearbox, adjusting ability is not strong, especially in the large reduction ratio,high discharge pressure situations.Under the premise of maintaining the same transmission route calculation, we simulatedwith three different gearbox case, cement truck discharge performance changes, so thatmulti-stalls, large the speed range of the gearbox, can make cement truck in the highdischarge pressure of the operating conditions, and more fine adjustment of the flow, sothat the stable operation of the device can be in the different construction conditions.The overall layout of the pump match engine and AMT gearbox, with a pole beam design,the interaction between the engine flywheel housing and AMT gearbox housing polebeams disperse and eliminate. Cement truck with good driving performance and safetyperformance, the design process is strict enforcement of the existing laws and regulationsto the motor vehicle axis charge distribution parameters limit the height of the center of mass, roll angle, rear angle, Gradeability pump vehicle structure design.In the AMT gearbox automatic control system using CAN bus communication. Enginestart, stop, acceleration, deceleration, the basic control of the transmission shift.Overpressure protection module, so that the machine has a safety valve and overpressureprotection the dual security settings, to improve the security of the whole machine.Finally, in strict accordance with the requirements of the SY/T5557-2009"cementingequipment specification", design the cement truck factory test test methods and testequipment, combined with the characteristics of the project products, determine thespecific requirements of the test. Matching12speed AMT gearbox cement truck inaccordance with the test requirements of the factory test, the test results show that thecement truck to meet the standard requirements, load test, with12blocked AMTtransmission work properly.It can be predicted that the large the AMT gearbox variable speed range, light weight, easeof maintenance, support CAN bus characteristics, it will be more and more widely used inthe field of cement truck application.
