How to maintain the battery extrusion test machine
- 2019-03-11 -

   The battery extrusion test machine checks the safety performance of the battery after kneading experiments. After the experiment, the battery should not ignite or explode; it is also an indispensable testing equipment for battery manufacturers and research institutes. The test battery was kneaded in two planes, and a kneading force of about 13KN was applied through a vise or a 32mm hydraulic cylinder. The kneading continued until the pressure gauge reading on the hydraulic equipment reached 17.2MPa. Once the pressure was reached, the 揉 was released. pinch. For cylindrical batteries, the long axis of the kneading cell should be parallel to the kneading plane of the kneading device. For prismatic cells, the pressure should be applied to one of the two axes perpendicular to its long axis, and then 揉Pinch the other axial, snap-on battery and knead its flat surface. Each test battery was only kneaded once.

The use of the battery extrusion tester is to check the safety performance of the battery after kneading experiments. After the experiment, the battery should not ignite or explode; it is also an indispensable testing equipment for battery manufacturers and research institutes.

Battery extrusion tester test method

The test cell was kneaded in two planes, and a kneading force of about 13KN was applied through a vise or a 32mm hydraulic cylinder. The kneading continued until the pressure gauge reading on the hydraulic equipment reached 17.2 MPa. Once the *max pressure was reached, Unscrew.

For cylindrical batteries, the long axis of the kneading cell should be parallel to the kneading plane of the kneading device. For prismatic cells, the pressure should be applied to one of the two axes perpendicular to its long axis, and then 揉Pinch the other axial, snap-on battery and knead its flat surface.

The battery extrusion test machine is also called the battery heavy impact tester. The internal test box is made of SUS#304 stainless steel plate, which is rust-proof, anti-corrosion and high-temperature resistant. The outer box is made of cold-rolled steel paint.

1. Cleaning: The battery impact tester wipes the instrument with cotton cloth before and after each experiment to keep the instrument clean and clean. The dirt can be used as a cleaning agent with anti-rust oil.

2, anti-rust: check the relative movement of the instrument is normal operation, the fixed rod regularly add butter every three months, to promote agility and increase life. The galvanized parts are sprayed once a week to prevent rust.

3. Power off: If the machine is not used, please plug the power supply. If it is not used for a long time, it is recommended to power it once a month.

The internal test box is made of SUS#304 stainless steel plate, which is rust-proof, anti-corrosion and high-temperature resistant. The outer box is made of cold-rolled steel paint. The air exhaust port is installed on the back of the box, and the fan heat is used in time. The upper and lower impact surfaces are made of steel plate, which is resistant to collision and structure. The controller is chosen to be separated from the experimental space to ensure the safety of the operator.
