Abstract
The utility model discloses a gas content measuring device, which comprises a cabinet which contains a small-sized vacuum pump, the small-sized vacuum pump is connected to a degasifier and a reference holder which are provided on the other side of the cabinet, and the degasifier and the reference holder are connected to a micromanometer which is provided in the cabinet. The utility model has the advantages of clever conception, simple structure, convenience for carrying and using, high measurement accuracy, reliable testing, stable system, low cost, short opening time and analyzing time, and good measurement reproducibility, besides, the free gas dissolved in the oil can be sufficiently pulled off.
Description
Affiliated technical field:
The utility model relates to the separation equipment in physical method or the device, is a kind of with the device of separating in the gas from liquid, specifically, is a kind of air content determinator.
Background technology:
Power equipment is made, operation department, often need measure, normally adopt vapor-phase chromatography to measure at present, when the application gas chromatograph is measured oil-filled electrical equipment oil dissolved gas component concentration, can only carry out in the laboratory, can't be carried to device context and measure.The gas chromatograph complex structure, the cost height, and also analysis time is long, and start needs 30～60 minutes, and concrete analysis was generally about 40 minutes.Gas chromatograph also be subjected to the influence of relevant corollary apparatus such as degasser, so test accuracy is not high, the poor reliability of data except that the systematic error of itself.
The utility model content:
It is simple and direct, easy to carry and use that the purpose of this utility model provides a kind of structure, and the measuring accuracy height is measured reliable, can fully deviate from the free gas that dissolves in the oil sample, system stability, cost is low, the good air content determinator of short measuring repeatability of start and analysis time.
Technical solution of the present utility model is: a kind of air content determinator, it is characterized in that: cabinet is arranged, minipump is housed in the cabinet, degassing container in minipump and the opposite side cabinet is connected with the reference container, and degassing container is connected with the reference container microbarograph interior with also being loaded on cabinet.
Vacuum pump described in the utility model adopts small-size rotary vacuum pump.Degassing container and vacuum pump lay respectively in the cabinet of both sides, cabinet in the middle of microbarograph is arranged in.There are oil feeder mouth, oil extraction valve port and vacuum pump exhaust tube access port in the cabinet outside that vacuum pump is housed.The oil feeder mouth adopts manual draw bar formula seal valve, and its port is with lucite pipe, and the other end inserts the oil sample container.Vacuum pump exhaust tube access port adopts rapid-acting coupling.Digital indication mechanism on the cabinet panel of degassing container is housed.
The beneficial effects of the utility model are: be skillfully constructed, structure is simple and direct, easy to carry and use, the measuring accuracy height is measured reliably, can fully deviate from the free gas that dissolves in the oil sample, system stability, cost is low, it is good to lack start and analysis time measuring repeatability.
Description of drawings:
Fig. 1 is the structural representation of a kind of air content determinator of the present utility model;
Fig. 2 is the principle of work synoptic diagram of air content determinator of the present utility model.
Embodiment:
Fig. 1 has described an embodiment of the present utility model, in this embodiment, cabinet 1 is arranged, minipump 2 (commercially available prod are housed in the cabinet 1, model 2XZ-03), degassing container 3 in minipump 2 and the opposite side cabinet 1 is connected with reference container 4, and degassing container (existing common matured product) 3 and reference container (existing common matured product) 4 connect with the microbarograph (model plum Teller 210 is now common matured products) 5 that also is loaded in the cabinet 1.Described vacuum pump 2 adopts small-size rotary vacuum pump (commercially available prod).Degassing container 3 and vacuum pump 2 lay respectively in the both sides cabinet 1, cabinet 1 in the middle of microbarograph 5 is arranged in.There are oil feeder mouth 6, oil extraction valve port 7 and vacuum pump exhaust tube access port 8 in cabinet 1 outside that vacuum pump 2 is housed.Oil feeder mouth 6 adopts manual draw bar formula seal valve (existing common matured product), and its port is with lucite pipe, and the other end inserts oil sample container 3.Vacuum pump exhaust tube access port 8 adopts rapid-acting coupling (existing product).Digital indication mechanism (existing product) 9 etc. on cabinet 1 panel of degassing container 2 is housed.
The course of work of the foregoing description and principle are:
Fig. 2 has described principle of work of the present utility model.Utilize oil-sealed rotary pump simultaneously degassing container and reference container to be vacuumized, after oil injects degassing container, dissolved gases is deviate under vacuum in the oil, vacuum tightness in the degassing container is changed, utilize the pressure reduction between microbarograph (pressure transducer) mensuration degassing container and the vacuum reference container again, this pressure reduction is proportional to the tolerance of deviating from the oil, thus, has just realized the accurate mensuration of air content.
Among Fig. 2,2 is vacuum pump, and 3 are degassing oil bottle, and 9 is digital indication mechanism, and 11 is the degas chamber in the cabinet, and 12 is the 10mL container, and 13 is stirrer, and 15 is two-position three way magnetic valve, and 16,17,18,19 is two three-way electromagnetic valves (closed types).
Claims (7)
