Description

A kind of electric energy method balance of well pumping unit proving installation

Technical field

The utility model is specifically related to a kind of electric energy method balance of well pumping unit proving installation.

Background technology

Balance of well pumping unit is an important indicator of oil pumper field management, each ore deposit of recovering the oil, team are in order to strengthen the oil pumper dynamic management, raise the management level, regularly balance of well pumping unit is carried out test analysis, because changing unbalanced oil well, the oil well production situation tests and adjusts balance for some timely, make it keep normal reasonably production status, play a role for the stable yields of effective prolongation oil pumper serviceable life, energy-saving and emission-reduction, maintenance oil well.

The method of testing of balance of well pumping unit has two kinds: the one, and current method; The 2nd, power method.The main problem that exists is as follows:

1, to test required instrument and meter mainly be reometer (digital electronic ammeter, pointer reometer) to current method, can only test operating any one the up-downgoing maximum current of oil pumper, can not three tests simultaneously.

2, because oil pumper up-downgoing maximum current is flashy, and digital electronic ammeter factor word shows the reason of refreshing frequency, possibly can't demonstrate maximal value; The pointer-type reometer then since when test pointer swing, can't in time correctly read current maxima.Therefore, no matter being to use digital electronic ammeter still is pointer reometer, and the electric current of testing is the maximum current of oil pumper up-downgoing not necessarily, thereby, can not carry out correct calculating and judgement to the balance of well pumping unit situation.

3, current method test can not judge that the oil pumper load has become big and still diminished according to the size of the electric current of different time test, more can not judge the size of the load of different oil wells according to the size of the electric current of test.

In patent (CN 02109945.6), a kind of method of testing and device of balance of well pumping unit are disclosed, current transformer is disclosed in the device part, voltage transformer (VT), multiplier, the I/F transducer, automatically pop one's head in, single-chip microcomputer, storer and LCD, described current transformer, voltage transformer (VT) links to each other with multiplier, described multiplier links to each other with the I/F transducer, described I/F transducer links to each other with single-chip microcomputer, described single-chip microcomputer respectively with automatic probe, LCD links to each other with storer, but do not realize reporting to the police, do not provide mechanical part in addition yet.

The utility model content

For solving the problem that prior art exists, the utility model specifically discloses a kind of electric energy method balance of well pumping unit proving installation.

The technical solution adopted in the utility model is as follows:

A kind of electric energy method balance of well pumping unit proving installation, comprise a support, on support, be provided with a display, described display links to each other with control device, and the below of display is provided with switch key, described control device comprises current transformer, voltage transformer (VT), multiplier, the I/F transducer, automatically pop one's head in, single-chip microcomputer and storer, described current transformer, voltage transformer (VT) links to each other with multiplier, described multiplier links to each other with the I/F transducer, described I/F transducer links to each other with single-chip microcomputer, described single-chip microcomputer links to each other with storer with automatic probe respectively, described single-chip microcomputer also with warning device, the USB flash disk interface, keyswitch links to each other, described warning device is for comprising three kinds of pilot lamp, and these three kinds of pilot lamp are represented the degree of unbalancedness of three kinds of grades respectively.

Described USB flash disk interface is used for reading the data of storer.

Described keyswitch is used for the unlatching of control single chip computer.

Described three kinds of pilot lamp are respectively red, yellow, green.

The course of work: the electric current that from current transformer and voltage transformer (VT), takes out and voltage signal input multiplier, do instantaneous multiplying each other and obtain power signal, be input to the I/F transducer, the output pulse frequency of I/F transducer is directly proportional with power input, the dead point control single chip computer of the upper and lower stroke of measuring with popping one's head in automatically of oil pumper is counted the output pulse of I/F transducer again, by the sum of pulse separately in the time separately of calculating up-down stroke.Calculate power consumption separately, and read for USB flash disk inside being stored in storer, when exceeding certain numerical range from power consumption, carry out the warning of three kinds of grades, and come the startup of control single chip computer by keyswitch.

The beneficial effects of the utility model are: this instrument can record the peak power in the oil pumper up-downgoing process automatically, three-phase power line is carried out balance test, pass through operating in a key, can finish the test of the peak power of oil pumper up-downgoing, in the quality of balance test that has realized oil pumper, realized warning function and data read functions at any time.
