The present invention relates to a detection equipment for detecting axial gap of inner spindle of pump body. Said detection equipment includes upper holddown mechanism, workpiece positioning mechanism, axial lifting mechanism and inner spindle rotating mechanism. Its upper holddown mechanism includes steam cylinder or oil cylinder, reference holddown block, press-in cylinder block, press-in motor, reductor, synchronous band, puller lever, press-in position sensor and height measurement sensor.

The invention discloses an automatic detector of the cleanliness of fibers and a detection method thereof. The automatic detector comprises a liquid storage box, a testing pipe, an LED light source, an illumination sensor and a liquid level sensor, wherein the liquid storage box is internally provided with a liquid level switch; the lower part of the liquid storage box is provided with a liquid inlet pipe connected with the testing pipe; the side surface of the liquid storage box is provided with a liquid overflow port, and the other side of the liquid storage box is connected with a cleaningelectromagnetic valve; the bottom end of the testing pipe is provided with the LED light source and a concave lens; the bottom of the testing pipe is connected with the liquid level sensor; the top end of the testing pipe is provided with the illumination sensor; the side surface of the upper part of the testing pipe is provided with a ventilation opening connected with the liquid overflow port; one side of the bottom of the testing pipe is connected with a liquid inlet electromagnetic valve, and the other side of the bottom of the testing pipe is connected with a liquid discharge electromagnetic valve; and one side of the testing pipe is parallelly provided with a calibration pipe. The invention adopts a vertical light path measuring method and has high measurement automation degree and accuracy; in addition, the influence of human factors and environmental factors on a measuring result is avoided, thereby a measuring result is objective and accurate.

The invention discloses a pre-type adjustable electromagnetic drainage valve for treating glaucoma, comprising a drainage plate, a drainage tube is arranged on the drainage plate, a drainage valve is arranged in the drainage tube, the drainage valve includes a magnetic valve block, and the magnetic valve block is There is a guide column, and a fixed block is provided on the drainage tube wall of the drainage tube. The guide column is sleeved through the fixed block. One end of the guide column is connected with the magnetic valve block, and the other end of the guide column is provided with a hard tip. The inner diameter of the drainage tube is along the The direction from the guide column to the magnetic valve block gradually decreases, and the wall of the drainage tube is in close contact with the outer periphery of the magnetic valve block. It also includes an external electromagnetic pole, and the external electromagnet is magnetically matched with the drainage valve. By changing the magnetic flux of the external electromagnet Control the movement of the diversion valve. The present invention can adjust the drainage volume of the drainage tube according to the actual use requirements through the cooperation of the external electromagnet and the magnetic valve block, and can also avoid the blockage of the lumen caused by tissue fibrosis, thereby realizing self-dredging and reducing the cost of surgery. failure rate.

The invention relates to a noncontact-type tear film breakup time measuring device and method. The noncontact-type tear film breakup time measuring device comprises a structured light projection unit, a first light splitter, a central positioning unit, a second light splitter, a focusing unit, an imaging unit, a shell, a base and a three-dimensional moving platform, the structured light projection unit projects structured light patterns of a certain mode to the surface of a tear film, structured light images modulated by the surface of the tear film are collected by the imaging unit, and whether the structured light patterns in the collected images are distorted or broken or not is detected through upper computer software so as to judge thinning and breaking conditions of the tear film. Tear film breakup time is measured by adopting a method of structured light detection, so that stability of the tear film is unaffected due to a noncontact measuring mode; the device can automatically recognize starting point and finishing point of tear film breakup time measuring to automatically complete the whole measuring process, thereby being objective and accurate in measuring result.

The invention aims to provide a quantifying method for bitter degree of a multi-component traditional Chinese medicine based on molecule bitter degree equivalent measurement; the quantifying method can effectively measure bitter degree of the multi-component traditional Chinese medicine, so that bitter degrees of different medicines as well as the medicine bitter taste masking problem are quantified and compared more accurately and objectively; a minimum limit method is adopted, bitterness threshold (BT) concentrations, namely lowest concentration tasted by half of volunteers, of water solutions of standard bitter substances and bitter-taste traditional Chinese medicine decoction pieces at 37 DEG C are measured; any standard bitter-taste substance is set, molecular bitter degree equivalentof a to-be-measured medicine is calculated according to a formula of EMBs equal to (Cr / Cs)*EMBr. The quantifying method can measure bitter degrees of bitter tastes of medicines, obtains accurate andobjective measured results, provides quantifying indexes for bitter degree evaluation of the medicines, provides technical support for medicine bitter-taste masking, develops a commercial value of themedicines, improves the taking effect of the medicines, and has remarkable economic and social benefits.
