Description

Cementing concrete truck

Technical field

The utility model relates to a kind of vehicle-mounted mobile cementing equipment that is applied to the middle and high press liquid instillation process of oil exploitation, especially relates to a kind of cementing concrete truck, is applicable to petroleum well field well cementation, pressure testing, mixes construction operations such as rare.

Background technology

At present, the cementing concrete truck that is applied to the petroleum well field construction operation generally adopts the mechanical gear box of three gears or the hydraulic transmission gear box of five to six gears.Adopt the cementing concrete truck of mechanical gear box, the discharge capacity scope can't satisfy complicated day by day well shaft fixing technology needs, and automation degree of equipment is low, and operating personnel need stand in directly gear shift operation of gearbox top, and labour intensity is big, and operating environment is abominable; Though and the cementing concrete truck that adopts hydraulic transmission gear box can be realized automation control, the flow oscillation between the different gears is bigger, is difficult to guarantee the accuracy of flow measurement in the field operation.In addition, on traditional cementing concrete truck, the fluid end grease pump of three-cylinder plunger pump is driven by the power takeoff of gearbox, and gearbox is as the power resources of lubricant passage way.Because the interface of traditional mechanical gear box power takeoff, installing space and gearratio restriction, usually adopt hydraulic gear pump, and metered flow and pressure are bigger, in real work, flow and the pressure of the fluid end lubricant passage way of three-cylinder plunger pump are less, therefore must install the overflow valve member additional at its lubricating loop, make hydraulic system more complicated, also be unfavorable for the maintaining of equipment.

The utility model content

Less in order to overcome existing cementing concrete truck discharge capacity scope, and flow oscillation is bigger between gear, and three-cylinder plunger pump fluid end lubricant passage way practicality is not good enough, equipment is controlled deficiencies such as inconvenience, and the utility model provides a kind of cementing concrete truck.

The technical scheme that its technical problem that solves the utility model adopts is: cementing concrete truck comprises a year chassis, ride table top, motor, gearbox, plunger displacement pump, reduction box, operating room, water tank, transmission system, manifold system, pneumatic diaphragm pump, on the ride table top, be installed with motor, gearbox, plunger displacement pump, pneumatic diaphragm pump, reduction box from front to back successively, gearbox is connected with plunger displacement pump by transmission system, and water tank is positioned at the afterbody of ride table top; Gearbox is 12 grades of AMT gearboxes, and 12 grades of AMT gearboxes are fixedly mounted on the ride table top.The quadruple board platform table top of installing at the reduction box place be positioned at reduction box above, operating room is fixedly mounted on the table top of quadruple board platform; Control system is installed in the operating room.The ECU of gearbox is connected with the selector of control system and EDC, the ECU of motor respectively by the CAN bus, and motor EDC, ECU also link to each other with Murphy Meter with the guidance panel of control system by engine control wire harness, CAN bus respectively.

The beneficial effects of the utility model are compact conformation, handiness; Discharge capacity control is finer and smoother, and the gear fluctuation is littler, reliable operation; Lubricant passage way simply is convenient to maintaining.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.But what those skilled in the art should know is to the invention is not restricted to the listed specific embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.

The utility model cementing concrete truck comprises a year chassis 1, ride table top 2, motor 3, gearbox 4, plunger displacement pump 5, reduction box 7, operating room 9, water tank 10, transmission system 11, manifold system 12, pneumatic diaphragm pump 6, on ride table top 2, be installed with motor 3, gearbox 4, plunger displacement pump 5, pneumatic diaphragm pump 7, reduction box 7 from front to back successively, gearbox 4 is connected with plunger displacement pump 5 by transmission system 11, and water tank 10 is positioned at the afterbody of ride table top 2; Plunger displacement pump 5 is three-cylinder plunger pump.Gearbox 4 is 12 grades of AMT gearboxes, and gearbox 4 is fixedly mounted on the ride table top 2, is fixed on the ride table top 2 by special-purpose shoulder pole girder structure usually.Because the AMT gearbox that adopts has the fluctuation between 12 gears, the adjacent gearratio littler, on the basis that increases cementing concrete truck discharge capacity adjustable range, discharge capacity control is finer and smoother, gear fluctuation is littler, is more suitable for pressurize, pressure testing and mixes rare etc. discharge capacity precision, pressure control being required higher job content.

Quadruple board platform 8 table tops of installing at reduction box 6 places be positioned at reduction box 6 above, operating room 9 is fixedly mounted on the table top of quadruple board platform 8 because the position height of operating room 9, operating personnel can guarantee to monitor in good visual angle water tank 10 water levels and motor 3 service behaviors.
