Tester for parameter of flow field of gas static pressure restrictor

Номер: CN102538876A
Автор: Li Dongsheng, Zhang Yubing, Shen Xiaoyan, Jin Liangbing, Lin Jiejun
Принадлежит:

The invention relates to a tester for a parameter of a flow field of a gas static pressure restrictor. A pair of guide rails is arranged at the middle upper part of a base, and a guide rail sliding block moves relative to the guide rails through a lead screw; a horizontal measurement working surface of a restrictor is fixedly arranged on the guide rail sliding block and is opposite to the gas static pressure restrictor fixed on the base, and a gas film with adjustable thickness is formed between the working surface of the restrictor and the gas static pressure restrictor. The working surface of the restrictor is provided with five sensor mounting holes in a straight line, the projection of the straight line on the gas static pressure restrictor passes through the central hole of the gas static pressure restrictor, and a sensor sensing probe in each mounting hole is level with the lower bottom surface of the measurement working surface of the restrictor. The tester can be used for measuring ...

Temperature real-time detector for flue-cured tobaccos

Номер: CN102879123A
Автор: Li Dongsheng, Jin Liangbing, Li Jiafu, Liu Yueyao, Zhang Yubing, Guo Chongchong
Принадлежит:

The invention discloses a temperature real-time detector for flue-cured tobaccos, and the conventional tobacco flue-cured humiture measuring instrument cannot be used for directly measuring the surface temperature of tobaccos, and is poor in measuring accuracy. In the detector, an input end of a tobacco temperature collection and conditioning module is connected with a platinum resistor placed on the tobaccos, and an output end of the tobacco temperature collection and conditioning module is in signal connection with an input end of a singlechip and AD conversion module; a curing barn environment humiture signal acquisition module is used for acquiring environment humiture signals, and an output end of the curing barn environment humiture signal acquisition module is in signal connection with the input end of the singlechip and AD conversion module; a clock module is in signal connection with the input end of the singlechip and AD conversion module; a liquid crystal display module is in ...
