3results about How to "Speed up testing" patented technology

This utility model relates to the field of solenoid valve testing technology and discloses a solenoid valve life test bench that is easy to fix. It includes a bench body, a vertical plate fixedly mounted on the upper end of the bench body, a groove formed at the upper end of the vertical plate, a movable component slidably mounted inside the groove, and a mounting groove formed at the upper end of the movable component. A test probe connected to a multimeter is mounted inside the mounting groove. A placement plate is fixedly mounted on the upper end of the bench body, and a fastening structure is provided on the upper end of the placement plate. The fastening structure includes a fastening seat fixedly mounted on the upper end of the placement plate, a fixing plate fixedly mounted on the rear side of the upper end of the fastening seat, a movable rod movably mounted inside the front end of the fastening seat, a movable plate fixedly mounted on the rear end of the movable rod, and a spring mounted on the outer wall of the movable rod. A solenoid valve body is positioned between the movable plate and the fixing plate. This utility model discloses a solenoid valve life test bench that is easy to fix, which can speed up the fastening of the solenoid valve and accelerate the energization test of the solenoid valve.

This invention belongs to the field of detonator wire testing technology, specifically a multi-type switching system and device for electronic detonator leads based on relay parallel connection, including a host computer; the host computer is connected to a test host device via signals; the test host device is connected to multiple sets of communication wire switching devices via signals; and the communication wire switching devices are connected to a module terminal test device via signals.

The utility model discloses a quick switching test loop for hydraulic valve detection relates to hydraulic detection technical field. Including hydraulic pump, motor, first overflow valve, pressure gauge, pressure sensor, first flowmeter, first ball valve, second ball valve, third ball valve, fourth ball valve, second flowmeter, second overflow valve, oil tank, four ball valves cooperate and open and shut and form two loops, one loop carries out cut -off test to pipeline explosion -proof valve, and another loop carries out reset to the pipeline explosion -proof valve in cut -off state, and first flowmeter can detect whether the cut -off flow of pipeline explosion -proof valve is up to standard, and according to the digital difference value of first flowmeter and second flowmeter judges whether pipeline explosion -proof valve has leakage. The utility model can avoid the frequent dismounting of each component of test pipeline in the testing process, reduce hydraulic oil leakage, effectively reduce the testing time, and accelerate the testing progress.
