Respectively from installing, dismantling, detect the principle of work that three steps set forth this pick-up unit.
Before installation, upper and lower two lids to screw in two threaded holes up and down of sleeve but all do not screw, two lids all do not contact with upper and lower two O-ring seals, two O-ring seals are in nature without compressive state, now the internal diameter of two O-ring seals is equal to the external diameter of battery, due to the size relationship of cell outside diameter and two internal diameter of the seal ring, mesuring battary after sidewall can punch by people very easily vertically inserts sleeve and ensures that battery is just stuck in the sleeve that do not drop out in two O-ring seals, and lower seal is then stretched out in the position of the bottom belt seal of battery, subsequently, people are by upper, lower two lids screw, two lids are made to be pressed on upper and lower two step surfaces respectively by upper and lower two O-ring seals, two O-ring seals are crushed, namely each O-ring seal along short transverse compressed can only radius vector to convex, internal diameter of the seal ring is caused to reduce with the sidewall of banding battery, now, upper and lower two O-ring seals, the middle battery via hole of sleeve and the sidewall of battery define closed pressurized chamber, the unique outlet of this chamber is exactly the boost port running through sleeve lateral wall, the air hole of battery sidewall is also positioned at this chamber, and this chamber is stretched out in the rear end of battery, people only need booster air pump, make pressure pipeline system just can realize detecting to this chamber supercharging through boost port.
During detection, drive air pump and open on-off valve, between on-off valve and pressure charging valve, there are two paths, one is through flow valve, two are through reduction valve and retaining valve, the aperture of flow valve is set to much smaller than reduction valve, as flow valve aperture is only 1/3rd of reduction valve, like this, most of gas flows to pressure charging valve through Article 2 path, and partial gas flows to pressure charging valve through Article 1 path, gas, through pressure charging valve supercharging, enters water tank, drives liquid to enter battery cavities inside through the blow vent of boost port, battery sidewall and realizes supercharging, in this process, a warning value more smaller than limit pressure can be designed in advance, as estimated, limit pressure is 41.6MPa, then setting warning value is 41MPa, first driving gas enters water tank from two paths, force value in the force value of boost port i.e. battery cavities is increased fast, once the tensimeter display pressure of boost port arrives warning value, then close reduction valve immediately, the major avenues of approach of Article 2 path and gas boosting is disconnected, only remaining partial gas flows through the first path, and then cause the force value of boost port slowly to increase after arrival warning value, until the seal of last battery quick-fried fall, the limit pressure of accurate acquisition seal.
During dismounting, unscrew upper and lower two lids, make it not recompress two O-ring seals, two O-ring seals reset and make its internal diameter also increase reset, and internal diameter recovers original size rapidly, and now battery is still blocked by two O-ring seals and do not drop, but one clap battery cephalosome gently, battery just drops automatically.
