Abstract
The utility model relates to a shift-loading combined sensor for pumping units in oil field, comprising a carrier assembled with sensors and an output cable, wherein, the carrier adopts an integrative structure; the strain gage of a load sensor and the chip of an acceleration sensor are respectively encapsulated in the performing hole of the carrier. Compared with the existing sensors, the utility model adopts an integrative structure canceling drawing wires and has the advantages of compact structure, small volume and easy processing, raising the measuring accuracy remarkably.
Description
The utility model relates to a kind of device that is used to detect the oil-field oil pumper operating mode, particularly surveys displacement-load combination sensor that its merit figure uses.
For accurately detecting the operating mode of oil-field oil pumper, sensor carrier is loaded on the outstanding of oil pumper holds on the device, utilize the upper and lower oscillation cycle motion of sucker rod, measure its displacement, load two parameters, the signal that records machine collection as calculated, handle, print the result, just can obtain the merit figure of oil pumper.This sensor carrier is the split-type structural that adopts a plurality of component-assembled to become, and load sensor wherein adopts the strain slice structure, be about to foil gauge with a plurality of component-assembled on carrier.Displacement transducer adopts gear, spring kinematic train or watch and clock movement kinematic train, drives pot with backguy and rotates, and utilizes the proportional relation of its output voltage and displacement, records displacement parameter.Because of said structure is a separate assembling, thus bulky, complex process, particularly its very long backguy, assembling, operation are pretty troublesome, the elastic performance of long backguy influences the reliability that pot rotates, and the measurement structure error is bigger, operating mode that can not the accurate response oil pumper.
The purpose of this utility model provides a kind of improved displacement-load combination sensor, and its adopts the monolithic construction of cancellation backguy, compares with existing sensor, has compact conformation, little, the easy processing of volume, significantly improves the advantage of accuracy of measurement.
The purpose of this utility model is achieved in that this device comprises carrier and the output cable that is assembled with sensor, and wherein carrier adopts monolithic construction, and the foil gauge of load sensor and the chip of acceleration transducer are packaged in respectively in the pre-manufactured hole of carrier.
Because the utility model adopts the carrier of monolithic construction, so obviously than the carrier structure compactness of existing split-type structural, volume is little, in light weight.The foil gauge of load sensor directly is encapsulated in the pre-manufactured hole of carrier, simplified processing process, be easy to processing, install, replace utilizing the gear of backguy control, the displacement transducer that the spring kinematic train constitutes with acceleration transducer, cancel backguy and kinematic train thereof, further reduce the volume and weight of carrier.The chip of acceleration transducer directly is encapsulated in the pre-manufactured hole of carrier, effectively overcomes the influence of backguy to measurement result, significantly improves the accuracy of measurement.Therefore, the utility model is easy to apply.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure synoptic diagram of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of the sensor of prior art.
Fig. 4 is the vertical view of Fig. 3.
Describe concrete structure of the present utility model in detail according to Fig. 1-4.This device comprises carrier 1, assembles load sensor, acceleration transducer and output cable 4 thereof in it.Wherein carrier 1 adopts monolithic construction, processes off-load hole and pre-manufactured hole on it, so that alleviate the weight of carrier 1 and be easy to encapsulated sensor.Load sensor adopts full-bridge strain slice structure; Displacement transducer adopts acceleration transducer, can be chip type structures such as pressure resistance type, Hall element formula, strain chip.Utilize acceleration transducer to need not the backguy of existing displacement transducer, can calculate its displacement from the accelerometer in its one-period.The foil gauge 2 of this device load sensor and acceleration sensor chip 3 be packaged in respectively in the same pre-manufactured hole of carrier or two pre-manufactured holes in.This foil gauge 2 or chip 3 usable resins or seal element are encapsulated in the pre-manufactured hole of carrier.During installation, carrier 1 is installed in the outstanding of oil pumper holds on the device, its output cable 4 is joined with computer control system get final product.During oil pumper work, this device can provide its load parameter and displacement parameter exactly, makes the merit figure of oil pumper after machine is handled as calculated, can grasp the operating mode of oil pumper at any time.
Claims (2)
1, a kind of displacement-load combination sensor that is used for oil-field oil pumper, comprise the carrier and the output cable that are assembled with sensor, it is characterized in that carrier adopts monolithic construction, the foil gauge of load sensor and the chip of acceleration transducer are packaged in respectively in the pre-manufactured hole of carrier.
2, sensor according to claim 1 is characterized in that described foil gauge or chip are encapsulated in the pre-manufactured hole of carrier with resin or seal element.
