Further, the test pressure that described high-pressure cylinder inner chamber is set is 2MPa ± 0.2MPa, cavity volume 2.1ml ±
2ML。
Further, the described sample needle diameter of bore that enters is 2.87 ± 0.05mm of φ.
Beneficial effects of the present invention：
Hand-held tool lithium battery test pressure feeder provided by the invention can compatible all lithium battery pressure tests will
Ask, in moment by 21ML ± 2ML, pressure 2MPa ± 0.2MPa air passes through pin that diameter of bore is 2.87 ± 0.05mm of φ
Pipe is passed through test sample inner chamber, and metering is convenient, and data reliability is strong.Meanwhile directly using the test of accurately supply gas pressure not only
Testing efficiency is high, and uses and deposit more convenient, Security of test height, ensure that tester's is safe to use.
Compared with existing cell pressure test equipment, hand-held tool provided by the invention lithium battery test pressure feeder
Using high-precision pressure gauge and syringe-type precise positioning flow, metering and data on flows are controllable, and test data is highly reliable.Using
Control manually so that installation cost of the invention is low, simple easy to operation.
