ting channel, the heating effect ideal. A heating device can be used for the sampler asphalt, and so easy as the medium tank.The sixth. The selftuning the position of the oil tank sampler The selftuning oil tank sampler The position of the oil tank sampler as shown in figure 5 shows 1, extendable frame。The first summarizeToday,internal sample of liquid dielectric in the oiltank is performed by ISO3170(GB/T47561998)《Petrol liquid product handicraft sample law》.It is impossibly to control accurately sample process. Usually the sample will not be personnels will feel tired as usual because of rain or snow, climb oiltank that is a very dangerous getting a sample at top of oiltank,easily volatile and noxious dielectric will injure someones,at one time,it will not be in favour of environment and the medium of oiltank will be polluted by other things from environment.For solving these problem, we have developed ” The auto control getting sample from oiltank” that according to 《ISO3170(GB/T47561998 criterion》,it has achieved that liquid sample at different level of oiltank will be sampled. The machine operation is very simply、very accurate、excellently repeated,it’s structure is simple and it will be install very easily. It will not pollute the environment too. The sample machine has been awarded nationalpatent and the second prize of the sino petrol amp。 apparatus Co.,Ltd by patentee for manufacture and sale. If others will manufacture and sell them ,they will break the law, the patentee will inquire their responsibility of law and call for economics pensation.The patentee’s signature:The designsketch in fact:The second sampler technology parameter:itemparameterCarried standardISO3170 GB/T 47561998《The petroleum liquid handicraft sample method》Usual sample dotdistribution settingUpper sample、middles ample、lower sample、upper middles lowe’s 1:1:1 uniform bination sample and bottoms ample、exits samples、upper sample(reference)Multilayer frame means expansion sample allowablehightReaching to the bottom of oiltank is 60025000mmApplicable mediumGas、kerosene、diesel、solvent oil、naphtha、petroleum aromatics、paraffindestillat、residual oil、heavy oil、crude oil、bitumen and so onSample hight locationerror177。 4, sampling bination tube。 8, adjustable bearing。The eighth.Sampler installation For drawing7For drawing7The ninth. sampler operating methods 11 /
