In the technique scheme, measuring tube is for bearing pressure, can seeing the round tube that indicates calibration data or rectangular tube, polygon pipe clearly again.
The accurate meter metering method of this hydraulic container or oil cylinder liquid level variable is: adopt heavy caliber hydraulic container or oil cylinder that piston is housed, hydraulic container or oil cylinder bottom connect small-bore measuring tube, be filled with hydraulic oil in hydraulic container or the oil cylinder, during measurement, the piston of heavy caliber hydraulic container or oil cylinder contacts with testee and advances a bit of distance, perhaps put into testee in heavy caliber hydraulic container or the oil cylinder, the hydraulic oil that heavy caliber hydraulic container or oil cylinder are discharged enters the displacement that small-bore measuring tube produces very big multiple, the length that the visual tolerance reading chi that is marked with according to small-bore measuring tube is read testee, displacement or volume precise information.
The principle of work and power of the present utility model and principle of work:
1. the principle of work and power: hydraulic container or oil cylinder are greater than visibility gage measuring tube, for example adopt circular hydraulic container or oil cylinder, its diameter is big, and the visual reading chi measuring tube diameter on installing is little, the distance that hydraulic container or oil cylinder piston move is long-pending with sectional area, make these hydraulic oil of discharge all enter visual tolerance reading chi measuring tube, because visual tolerance reading chi measuring tube sectional area is at double less than the sectional area of hydraulic container or oil cylinder, so, the distance that moves at visibility gage measuring tube is just amplified at double
2. being 1 meter in cylindrical hydraulic container or oil cylinder radius is 0.1 millimeter ratio with cylindrical visual tolerance reading chi measuring tube radius, and turning micron into is 100 microns of 100 0 000 microns ratios, and radius length is than being 10000:1
Sectional area ratio is calculated as:
1 000 000x1,000 000x3.14=, 3 140 000 000 000 square microns
100x100x3.14=31400 square micron
The area ratio is: 100 000 000:1 so, during 1 micron of the Piston Compression of hydraulic container or oil cylinder, there is the hydraulic oil of 3,140 000 000 000 cus to enter in the visibility gage measuring tube that sectional area is 31400 square microns, stroke distances length is 100 000 000 microns, but apparent displacement has amplified 100,000,000 times.Equally, when 0. 00001 microns of the hydraulic container that naked eyes be difficult to be found or the piston displacements of oil cylinder, the hydraulic oil stroke distances length that flows into visibility gage measuring tube is 1000 microns, be that the visual length of naked eyes is 1 millimeter, accurately measured the subtle change that naked eyes are difficult to 0.00001 micron of the piston displacement found dexterously.
Equally, with the cylindrical hydraulic container of 5 20 centimetres of radiuses or oil cylinder and the 0.1 millimeter visual tolerance reading of radius chi as complex liquid pressure vessel or oil cylinder, when the piston of hydraulic container or oil cylinder all compresses 1 micron, there is the hydraulic oil of 3,140 000 000 000 cus to enter in the visibility gage that sectional area is 31400 square microns, stroke distances length is 100 000 000 microns, but apparent displacement has amplified 100,000,000 times.Equally, when 0. 00001 microns of the hydraulic container that naked eyes be difficult to be found or the piston displacements of oil cylinder, the hydraulic oil stroke distances length that flows into the visibility gage is 1000 microns, be the visual length of naked eyes is 1 millimeter, in a disguised form measured the subtle change that naked eyes are difficult to 0.00001 micron of the piston displacement found.This principle is effective foundation of accurate measuring length, area, volume, volume, pressure, accurate displacement.In conjunction with practical application, according to different demands, arbitrarily regulator solution pressure vessel or oil cylinder radius and visibility gage radius ratio can satisfy little to volume under different lathes, different industries, the different mechanical special construction condition and requirement that the processing precise degree is high fully.
Principle of work:
Before the range finding work, close the hole pipe that adds hydraulic oil.Connecting rod is subjected to the external force effect, promote to connect the piston pressure sheet, and piston is in hydraulic container or oil cylinder when mobile, the influence that is stressed of hydraulic oil in the container is pressed into the visual pipe of liquid measure, when the visual pipe of liquid measure is emerged hydraulic oil, formation is full of oily air-free state in the container, enters distance measuring states.Determine earlier to survey thing centimetre and mm length, load onto visual centimetre of reading chi measuring tube on demand respectively, the visual reading chi measuring tube of millimeter, micron reading chi measuring tube, when piston continues when stressed, compress into the hydraulic oil of visual centimetre of reading chi measuring tube, centimetre reading that converts exactly and obtain, equally, compress into the hydraulic oil of visual millimeter reading chi measuring tube, the millimeter reading that converts exactly and obtain, compressing into visual micron reading chi measuring tube hydraulic oil is exactly the micron reading that converts and obtain, and conversion obtains the nanometer reading.The hydraulic oil that is forced out can all be recycled to the hydraulic container or the oil cylinder of conversion, by compression piston, as syringe, compresses into the measurement that circulates of hydraulic container or oil cylinder once more.
The utility model utilizes the difference of hydraulic container or oil cylinder and measuring tube caliber size dexterously, realize liquid level variable, make numerical value thousands of times of amplifications on the visual liquid measure reading of small-bore measuring tube chi such as measured length, area, volume, flow, pressure, displacement, thereby can break through conventional art and measure and to reach millimetre-sized limitation, the utility model has solved these technical barriers of field of measuring technique, precision can reach micron order, nanoscale, is the once leap and the breakthrough of measuring field of measuring techniques.The utility model is skillfully constructed, reasonable in design, principle is reliable, simple and practical, the demand that adapts to industrial and agricultural production, national defense construction and the research work of develop rapidly, for progress of science and technology provides a kind of convenience, suitable, reliable, high in technological content novel metering method and device, use extremely extensive.
