Control System Product introduction The composite salt spray test chamber is used to test the battery pack or the system casing for a certain period of time and its corrosion resistance. At the same time, it can also be used for the corrosion resistance of the surface of various materials after electroplating, anodizing, spraying, anti-rust oil, etc. Test description Testing object:Battery pack or system Standard test requirements: Refer to the test method of 5.5.2 of GB/T 28046.4 and test according to the test conditions of GB/T 2423.17. The salt solution is prepared using sodium chloride (chemically pure, analytically pure) and distilled or deionized water at a concentration of (5 ± 0.1)% (mass fraction). The pH was measured between 6.5 and 7.2 at (20 ± 2) ° C.

The test object was placed in a salt spray box and cycled as shown in Figure 10, one cycle lasting 24 hours. The test subject was sprayed at (35 ± 2) ° C for 8 h, then allowed to stand for 16 h, and the working mode was 3.2 in accordance with the requirements of GB/T 28046.1-2011 between the 4th hour and the 5th hour of a cycle.A total of 6 cycles For test objects installed in the passenger compartment, luggage compartment or cargo compartment, no salt spray test may be carried out.

GB/T 31467.3-2015 This test equipment simulates the corrosion test in an artificial environment, and is used to test the relative quality of metal materials with or without corrosion protection; it is suitable for rapid analysis of corrosion, such as discontinuities, pores and damage in organic and inorganic coatings. Testing, in addition, for quality control purposes, can be compared between samples coated with the same coating; salt spray testing is particularly suitable for detecting discontinuities in certain metal, organic, anodizing and conversion coatings, such as Holes and other...

The emergency stop switch can be used to stop all tests and cut off the power supply at the same time to avoid short circuit hazards. 4. Squeeze limit protection device Both the main cylinder and the auxiliary cylinder are respectively equipped with upper limit and lower limit protection devices. 5. Equipment overpressure protection The oil source system installs the system pressure protection module. When the pressure exceeds the set value, the oil circuit system automatically releases pressure to protect the oil circuit and the host. At the same time, motor over-current protection, upper...
