Description
Technical field
The utility model belongs to oil gas reclaimer field, specially refers to a kind of multifunctional comprehensive detector in refuelling station's oil gas removal process.
Background technology
Along with the reinforcement of environmental protection consciousness, the pollution problem of refuelling station has obtained the extensive attention of society, and the oil gas that overflows in group refueling and transportation becomes urgent problem to environment damage and to the waste of resource.But at present, refuelling station's oil gas recovery operation of China is scarcely out of swaddling-clothes, and gas recovery system for oil also mainly is to rely on external imported product, but in use, because refuelling station's infrastructure condition exists than big-difference both at home and abroad, causes imported product can't normally play a role at home; And owing to domesticly start late in this field, so far also there is not a tame specialized agency to detect to this series products, therefore in use, gas recovery system for oil tends to break down even quit work, and the refuelling station can't in time understand as the user.For this reason, our company has developed the multi-tester at gas recovery system for oil, this detector can detect the working condition of gas recovery system for oil in the refuelling station, important indicator to gas recovery system for oil, show intuitively and judge as the gas liquid ratio A/L of nozzle, the leakproofness of gas recovery system for oil and the liquid resistance in the pipeline etc., guarantee that the oil gas recovery operation normally carries out.
Summary of the invention
The problem that the utility model need solve is that multi-functional oil gas of invention reclaims overall checkout equipment, realize the multiparameter of gas recovery system for oil is detected, and solve the existing product function singleness, carry inconvenience, problem such as detection method is loaded down with trivial details.For this reason, need a kind of multi-functional checkout equipment of design, realize reclaiming the accurate measurement of oil gas, and realize that unit can detect all parameters of gas recovery system for oil, have the little characteristics such as easy to carry, simple to operate of high universalizable, volume.Technical scheme that the utility model adopts is as follows: be used for the comprehensive detector that oil gas reclaims, comprise parts such as intelligent gas Roots type flowmeter, high-precision pressure sensor, pipeline, the joint that matches with it and panel, install bin, it is characterized in that, described intelligent gas Roots type flowmeter is main measuring instrument, flow to oil gas in the gas recovery system for oil detects, flow comprises integrated flux and instantaneous delivery, draws the gas liquid ratio parameter of gas recovery system for oil by the contrast of oil gas flow in the oil gas removal process and fuel charger volume read-out; Described high-precision pressure sensor is the line pressure measurement instrument, can guarantee that error is to be accurate to Pa in 0.2% the scope, internal pressure to gas recovery system for oil is measured, comprise oil tank internal pressure and line pressure, the numerical value by pressure reflects the leakproofness situation of gas recovery system for oil and the liquid resistance size of reclaim line; Described pipeline is a gas circuit interface channel between the instrument, comprises pipe fittings such as straight tube, elbow and threeway, has guaranteed the entire equipment of contacting under the unobstructed situation of gas circuit, and sealing fully, guarantees the precision of equipment; Described joint is the end of pipeline, the port that is connected with gas recovery system for oil comprises pipeline fast joint and needle-valve, and the equipment that guaranteed can be connected simply fast with gas recovery system for oil to be detected.Described panel has guaranteed that equipment integral is attractive in appearance, and is intuitively comfortable when the operator reads registration; Described install bin is the external support part of equipment, and main test instrumentation and accessory are placed in wherein, and have parts such as handle, steamboat and pull bar, have guaranteed the portability of equipment energy.
When gas recovery system for oil is carried out conventional sense, the top cover of opening installation case at first, expose panel and 3 joints, when measuring the gas liquid ratio of gas recovery system for oil, two adapters of adapter are linked to each other with the gas outlet with air intake opening respectively, and air intake opening and gas outlet are connected to the two ends of intelligent gas Roots type flowmeter, thereby form complete fairway, the intelligent gas Roots type flowmeter is connected in wherein, measures the gas liquid ratio parameter that reclaims oil gas by it; When measuring the leakproofness parameter of gas recovery system for oil, air intake opening and gas outlet are closed, nitrogen cylinder is connected the nitrogen air intake opening, nitrogen air intake opening place is provided with a needle-valve, and with the pneumatic polyphone that connects soon, by the regulatory function of needle-valve, nitrogen is squeezed in the gas recovery system for oil, the size that keep-ups pressure is for about 500Pa, and maintenance a period of time is that leakproofness is qualified; When measuring the liquid resistance of gas recovery system for oil, connected mode is consistent with the leakproofness test, and nitrogen is charged in the gas recovery system for oil with certain flow rate, observes the tensimeter registration and changes, and being not more than standard figures with maximal value is criterion of acceptability.By said process as can be known, oil gas reclaims the accurate detection that comprehensive detector has not only been realized the oil gas removal process, also realized the detection of unit to all parameters of gas recovery system for oil, measurement versatility, dirigibility and comprehensive have been strengthened, and easy to carry, use simply, satisfied all kinds of detection requirements to gas recovery system for oil.
The beneficial effects of the utility model are that use oil gas reclaims comprehensive detector, makes oil gas reclaim more exchange device of testing process, has realized that unit detects comprehensive parameter, has increased measurement versatility, dirigibility and comprehensive.
