Abstract
The utility model relates to an indicator diagram testing device for a permanent type oil pumping machine for oil fields. The utility model is composed of a load sensor, a displacement sensor and a data acquisition analysis instrument, wherein, the load sensor and the displacement sensor are arranged on the oil pumping machine for a long time, under the condition of the machine is not stopped, the portable data acquisition analysis instrument can be connected with the interface of the sensors at any time to test and record the indicator diagram of the oil pumping machine, which simplifies the operation procedures, reduces the current attack when a motor is started or stopped and protects the motor of large oil pumping machines and devices thereof. The utility model has an important significance for collecting the working state of the oil pumping machine at fixed periods and adjusting and ensuring the production of each oil well.
Description
The utility model relates to a kind of oil field permanent setting type pumping-unit workdone graphic proving installation, relate in particular to and a kind ofly be placed in load transducer and displacement transducer on the oil pumper for a long time, and the data collection and analysis instrument adopts portable mode to dock image data at any time with sensor, the device of test means for oilfield oil pump indicating diagram.
The oil field has the pumping-unit workdone graphic proving installation now, is the independent test system that separates with oil pumper.During the test pumping-unit workdone graphic, measure after needing to shut down installed load sensor and displacement transducer.Though a kind of portable load-position diagram device of not shutting down test has also appearred in the oil field at present; but still exist loading and unloading inconvenient; accident easily causes casualties; and shortcoming such as testing apparatus is impaired; and the displacement sensor adopts the stay-supported structure; not only short measuring accuracy is not high the life-span, is difficult to satisfy simultaneously open-air oil pumper long-term work needs yet.
The purpose of this utility model, be for the oil field provide a kind of easy and simple to handle, measuring accuracy is high, is applicable to the proving installation of the permanent setting type means for oilfield oil pump indicating diagram of field environment work.
The purpose of this utility model is achieved in that hermetically sealed integrated load transducer is fixedly arranged in the oil pumper lifter, the displacement transducer of permanent-magnet steel and Hall element composition is fixedly arranged on balance of well pumping unit piece and the oil pumper support, data collector then adopts portable mode to connect with each sensor at any time and gets final product each well data of acquisition and recording, thereby tests out means for oilfield oil pump indicating diagram.
After the utility model adopts above-mentioned design, only need harvester is connected with sensor, can under not shutdown situation, test out pumping-unit workdone graphic, operate very simple.Load transducer is fixedly arranged in the lifter, owing to adopt hermetically sealed integral structure, so be applicable to field work.Simultaneously, load transducer also has the standard signal output characteristics.Displacement transducer adopts permanent magnet steel and Hall element in addition, has characteristics such as measuring accuracy height.Data collector is convenient for carrying, and is adapted to field work, has the functions such as well data, self-calibration function and man-machine conversation that acquisition and recording is got more than 100 mouthful of well simultaneously.
Further narrate the utility model below in conjunction with accompanying drawing:
Fig. 1 is the utility model sensor scheme of installation.
Fig. 2 is a data system analysis instrument synoptic diagram of the present utility model.
This utility model is by load transducer 1, displacement transducer, connector box 4, and data collection and analysis instrument 5 and acquisition and analysis instrument interface 6 are formed, and displacement transducer is made up of Hall element 2 and permanent magnet steel 3.Load transducer 1 is installed on oil pumper and promotes on the steel cable, the Hall element of displacement transducer partly is installed on the gantry base of oil pumper, the magnet steel partial fixing of displacement transducer is on the balancing stand of the rotation of oil pumper, and guarantee to produce pulse signal to Hall element in the magnet steel motion process, after passing through signal Processing then, the standard signal of load transducer and displacement transducer is introduced terminal box simultaneously.
Under non-stop-machine situation; only need the data collector interface is docked with sensor terminal box interface; can gather out the signal of load transducer and displacement transducer; finish the measurement of load and displacement size; draw out the load-position diagram of oil pumper, thus complete and accurate analyze the working condition of oil pumper.
When the oil pumper lifter safeguarding and situation such as maintenance under with the load transducer unloading after, this utility model operating instrument can carry out a zero value collection, storage automatically, and the load value of being gathered is calibrated automatically the self-calibration function of this utility model that Here it is with this zero value.
Because the maximum address scope of MCS-51 series monolithic is 64KB, and the address space that can be used for stored data will be less than 64KB, therefore to 100 mouthfuls of storages more than the well, this utility model has adopted the expansion technique of high capacity storaging chip and super 64KB memory space, stores the above data-storing requirement of 100 mouthfuls of wells thereby reached.
This utility model adopts the lattice lcd display and the standard universal keyboard of giant-screen wide temperature range in addition, and each operation steps is all undertaken by character reminding, thereby makes this utility model possess interactive function.
