摘要： The present invention provides a defect inspection apparatus and a defect inspection method that allows easy and efficient inspection of a defect of a porous hollow fiber membrane. The defect inspection apparatus for a porous hollow fiber membrane of the present invention includes: a container storing a fluid; a passage member that is configured such that a hollow fiber membrane travel passage, which allows the porous hollow fiber membrane to pass therethrough continuously, is formed thereinside and the passage member being disposed in the fluid to thereby fill the passage with the fluid; a restriction means that restricts travel of the porous hollow fiber membrane such that the porous hollow fiber membrane passes through the fluid in the hollow fiber membrane travel passage of the passage member; a fluid suction means that flows the fluid in the hollow fiber membrane travel passage to thereby lower the pressure of the fluid in the hollow fiber membrane travel passage; and an air bubble detection means that detects an air bubble that is released into the fluid from a defect of the porous hollow fiber membrane. A defect inspection method for a porous hollow fiber membrane using the abovementioned defect inspection apparatus.

摘要： A valve assembly for detecting leaks in fluid systems which includes an airtight transparent cup means at least partially filled with liquid and a plunger means provided with an orifice and a tube means interconnecting said orifice and liquid. The valve assembly is connected into the fluid line so as to allow the fluid to pass therethrough unimpeded. Depression of the plunger effectively closes the fluid line except for the passageway afforded by the orifice and the tube positioned in the liquid. The existence of a leak in the fluid system is thereby easily observed by a fluid flow through the liquid, i.e., bubbles, etc.

摘要： An automated test apparatus for risk and integrity testing for pharmaceutical filtration membranes, including at least the following components: a liquid injection inlet, a pump, a fluid pressure gauge, a gas pressure gauge, a plurality of solenoid valves, a plurality of membranes, a gas pressure regulator valve, a pharmaceutical product bottle, and a bubble generation bottle. The automated test apparatus of the present invention is controlled by computer software in connection with an automatic pharmaceutical synthesis apparatus for automated testing. In use of the automated test apparatus of the present invention, it needs only to start the operating system of the automated test apparatus for membrane risk and integrity test after the completion of the automatic pharmaceutical synthesis. The membrane risk and integrity test can be accomplished in a short time by measuring pressures of gas and liquid with pressure gauges deposed online concurrently.

摘要： A compressor leakage detector includes a water tank, an elevator platform, a control panel, and a pressure testing unit. The elevator platform is disposed in the water tank to rise and drop vertically. The operating panel of the control panel has a human-machine interface, indicators, and pressure gauges. The pressure testing unit in the control panel uses an intake pipe to connect to several branch pipes that in turn connect to the compressors in the water tank. Each of the branch pipes connects in series to at least one intake EM valve and at least one exhaust EM valve. A pressure sensor is interposed between the intake EM valve and the corresponding compressor.
