ISO 16750-4:2006: International common vehicle electrical equipment test framework, compatible with customized cycles (e.g. 100 standard or 200 enhanced).
Third, optimize standards by using manufacturers' technical resources
Flexible parameter adjustment:
Temperature range: standard high temperature range 65~160℃, can be extended to-70℃ to +150℃;
Water splashing system: support flow (3~4L/3S or 80L/min), distance (325±25mm adjustable), nozzle type (gap/matrix) and other customization;
Intelligent control: the PLC system can customize the temperature switching rate (such as 20 seconds to complete the conversion from extreme cold to high temperature), data acquisition frequency and report format.
Function module superposition:
Compatible with multiple test requirements such as waterproof (IPX5-6) and dustproof (IP5X-6X);
Support dynamic Angle spraying (15 ~75 adjustable), salt spray composite test and other complex scene simulation.
4. Ensure compliance through certification and verification
Equipment calibration: the manufacturer provides half-year temperature sensor calibration service, the error is controlled within ±2℃;
Third-party verification: it is recommended to certify the temperature change rate, uniformity and other indicators of customized equipment through quality inspection institutions (such as China Electric Power Research Institute, FAW test site);
Data traceability: The test chamber supports USB export of test logs, which is convenient for quality traceability and standard iteration.
5. Service support and case reference
Technical team: Guangdong Hongzhan cooperates with universities and research institutes to provide whole-process support from demand analysis to standard implementation;
Case library invocation: You can refer to the car company case (such as 800V battery pack IPX9K test, intelligent lamp cold and hot cycle verification) to optimize and customize the standard;
After-sales guarantee: customized equipment enjoys 1 year warranty and 48 hours door-to-door maintenance to ensure the stability of standard implementation.
1. O condensador (ou radiador) da unidade de refrigeração no câmara de teste de choque térmico e frio Deve ser mantida regularmente para garantir que permaneça limpa. A poeira aderida ao condensador pode causar o disparo do pressostato de alta pressão do compressor, levando a alarmes falsos. O condensador deve ser limpo mensalmente com um aspirador de pó para remover a poeira da malha de resfriamento do condensador ou, após ligar a máquina, com uma escova de cerdas duras para limpá-lo ou soprar a poeira com um bico de ar de alta pressão.2. Ao abrir ou fechar a porta ou retirar o objeto de teste do forno, não deixe o item tocar na borda de borracha da porta para evitar que ela seja danificada e reduza sua vida útil.3. Mantenha o solo ao redor e sob a fuselagem sempre limpo para evitar acidentes e degradação do desempenho causados por grandes quantidades de poeira sugadas para dentro da unidade.4. O sistema de congelamento da câmara de teste de choque a frio e a quente é o núcleo desta máquina. Inspecione todos os tubos de cobre quanto a vazamentos e condições de neve a cada semestre, bem como todos os bicos e juntas de solda. Em caso de vazamento de óleo, informe a empresa ou resolva-o diretamente.5. O contato de alta corrente do painel de distribuição deve ser limpo e reparado pelo menos uma vez por ano na sala de distribuição. O afrouxamento do contato colocará todo o equipamento em funcionamento em condições de risco. Na melhor das hipóteses, queimará os componentes e, na pior, causará incêndio, alarme e ferimentos pessoais. Ao limpar, use um aspirador de pó para remover a poeira do ambiente.6. Não ajuste o valor de ajuste dos dois protetores de sobretemperatura na caixa de distribuição de energia da câmara de teste de choque a frio e a quente de forma descuidada. O valor de ajuste é de fábrica. Este interruptor de proteção é usado para proteger o tubo de aquecimento contra queimaduras e alarmes. O ponto de ajuste é o ponto de ajuste de temperatura de 20°C a 30°C.7. Câmara de teste de choque frio e quente Quando o produto de teste for retirado quando chegar a hora, ele deverá estar desligado e a equipe deverá usar luvas secas, antieletricidade e resistentes à temperatura para retirar e colocar o produto.8. Limpe e faça a manutenção interna e externa da câmara de teste de choque térmico e frio. 9. Antes de operar a câmara de teste de choque térmico e frio, remova quaisquer impurezas internas. 10. A sala de distribuição elétrica deve ser limpa pelo menos uma vez por ano. Durante a limpeza, utilize um aspirador de pó para remover a poeira. A parte externa da câmara deve ser limpa pelo menos uma vez por ano, utilizando água com sabão.
