Background technology
At present, use measuring tank volumetric method gauging at the on-the-spot gauging of the individual well of petroleum industry, maximum shortcoming is that error is big more.Analyzing main cause is the vertical skewness of crude oil gassiness in the measuring tank, can't measure the former oil volume after outgasing fully.As change the former weight of oil of survey, and can effectively avoid the gassiness influence in the crude oil, mass method gauging technology mainly contains the metering of weighing, glass tube oil gauge and pressure capsule system gauging at present.Time-consuming, the effort of the gauging that weighs, the cost height, control program is loaded down with trivial details, promptness is poor.Glass tube oil gauge must guarantee that end water is arranged all the time, and end water do not infected, otherwise metering is inaccurate, and to winter, glass tube freezes easily, freezing can't the use.Pressure capsule system gauging cost is higher, to the high-viscosity oil bad adaptability, and is not durable, and is not suitable for promoting.
Summary of the invention
The purpose of this utility model provides former oil float support Weighing device, reduces the error in dipping of live crude, uses the weight method gauging, improves the accuracy of metering.
Use the present technique solution can reach above-mentioned purpose: former oil float support Weighing device comprises floating drum, walking beam and the stone roller of weighing, walking beam is provided with rider, floating drum is fixed on an end of walking beam by connecting hinge, the other end of walking beam hangs the stone roller of weighing, the balance fulcrum is fixed on the body wall of tank body, is supporting walking beam.
The utility model compared with prior art has following useful effect: the utility model is finished according to archimedes' principle the weight method of crude oil or other liquid is measured." the suffered buoyancy of object equals the weight that object arranges liquid " designs this device according to archimedes' principle.By adjusting rider and the weight of the stone roller of weighing, make beam balance, realize measurement to the suffered buoyancy of floating drum.Because floating drum is a cylindricality, the constant cross section at differing heights place, the fluid pressure that therefore suffered buoyancy and floating drum bottom surface are subjected to is linear.The head of liquid that is subjected at the bottom of the tested like this measuring tank jar can reflect by the weight calibration value of rider counterweight on the position of rule on the walking beam and the stone roller of weighing, and measures the result accurately by calculating to draw.More existing method of measurement of the utility model and metering outfit, accurate measurement, simple in structure, be easy to processing and fabricating, economy and durability.Be not subjected to temperature, light and the influence in season in the measuring tank.Floating drum is closed and is installed in the measuring tank, thereby effectively avoids H 2S poisons and the stolen phenomenon of crude oil, is easy to promote.Use this device to carry out crude oil measurement need other not thread a pipe on the measuring tank that is measured in load.The measured medium wide accommodation, no matter be uniform liquid, still non-homogeneous liquid, even the bigger crude oil of the viscosity of gassiness is as long as there is the liquid of certain fluidity all can use.
