    摘要： The present invention discloses a method for inspecting sealability of a vacuum chamber. The vacuum chamber has a closed site in which two sealing rings are arranged in such a way that the two sealing rings form therebetween a sealed compartment. The sealed compartment has a wall in which an evacuation hole is formed. The method for inspecting sealability of a vacuum chamber includes: connecting an evacuation valve through a pipe to the evacuation hole to form evacuation piping; mounting a pressure meter to the evacuation piping; opening the evacuation valve to proceed with evacuation of the sealed compartment and, during the evacuation process, monitoring the pressure meter; and determining sealability of the two sealing rings according to a reading of the pressure meter. The present invention allows for quick evacuation of the sealed compartment and to determine the sealability of the two sealing rings according to the pressure meter.

    摘要： For leak testing closed containers (9) which are filled with a filling product containing at least one liquid component the container is introduced in a test cavity (1) which is evacuated at least down to vapor pressure of that liquid component. The pressure in the surrounding of the container (9) and thus within test cavity (1) is monitored. Monitoring is performed by a vacuum pressure sensor (7), whereas lowering pressure surrounding the container (9) is performed by a vacuum pump (5). Leakage is detected by monitoring a pressure change in the surrounding of the container which is due to evaporation of liquid emerging from a leak and being evaporated in the low pressure surrounding.

    摘要： Improved high speed helium leak-detection system for storage tanks comprising a mobile enclosure for operation of electrical components of leak detection sensors in Class 1, Division 1, Group D hazardous locations, comprising a rapid exchange purge assembly having pressure control valves, pressure reference controller and vent, a mechanically actuated vortex-type cooler, a helium leak detector having a pumping manifold connected to a sniffer probe hose to provide sample gas from the tank probe to a pair of pumps oriented in parallel. The first pump, downstream of the helium leak detector, draws a sample through the detector, and a second pump provides a rapid transfer of probe sample. The enclosure includes a controller, display and alarm. The enclosure is maintained overpressure to prevent infiltration of hazardous vapors and is continuously purged with com-pressed air. The system provides response time of about 2 seconds, a 5-fold improvement over current systems.

    摘要： Method of testing a gas injector valve for a combustion engine. The valve is placed in a holder (1) with a first chamber (2) and a second chamber (3), the valve spraying nozzle (11) being placed in the first chamber (2), after which the valve in a closed condition is influenced by a test gas under pressure to control whether the valve seat and the valve gaskets (13a, 13b) are leak proof. This method makes it possible to indicate the position of a leak if any.
