Предложения по закупке автомобильных тормозных шлангов

Когда наши клиенты покупают автомобильные тормозные шланги, мы хотим указать следующие ключевые факторы:

1. Тип спецификации:

• Внутренний и внешний диаметры: The inner diameter should match the brake system's pipe fittings to ensure smooth fluid flow. The outer diameter must fit the installation space without interfering with other components.

• Длина: Select brake hoses of appropriate length based on the vehicle's brake system layout to facilitate installation without compromising system performance.

• Материалы: High-performance vehicles or racing cars typically use braided silicone brake hoses (commonly known as steel braided hoses) to enhance heat and pressure resistance.

  
  

2. Требования к давлению:

• Рабочее давление: The brake system's working pressure is typically around 1000 psi (approximately 70 bar). Therefore, the brake hose's rated working pressure should exceed this value to ensure safety.

• Взрывное давление: The brake hose's burst pressure should be at least four times the working pressure, i.e., approximately 4000 psi (about 280 bar), to provide sufficient safety margin.

• 

• 
  

3. Стандарты и аккредитация:

• Стандарты SAE: The Society of Automotive Engineers (SAE) has established several standards related to brake hoses, such as the SAE J2494 series, which covers the dimensions and performance requirements for automotive air brake pipe fittings.

  
  

• Сертификация DOT: The U.S. Department of Transportation (DOT) has stringent certification requirements for brake hoses to ensure their performance under high-temperature and high-pressure conditions.

• 
  

4. Термостойкость:

• Диапазон рабочих температур: Brake hoses should withstand the high temperatures of brake fluid, typically required to operate between -40°C and 150°C. High-performance brake systems may require higher heat resistance.
• 
  

5. Совместимость:

• Тип тормозной жидкости: Ensure the brake hoses are compatible with the type of brake fluid used (e.g., DOT3, DOT4, DOT5.1) to prevent chemical reactions that could lead to hose aging or damage.
• 
  

6. Выбор поставщиков:

• Репутация и качество: Choose suppliers with a good reputation and quality assurance to ensure products meet the above standards and requirements.

• Послепродажное обслуживание: Quality after-sales service can provide timely support and solutions if issues arise with the products.

Перед покупкой рекомендуется проконсультироваться с профессионалом или техником, чтобы убедиться, что выбранный тормозной шланг полностью соответствует требованиям вашего автомобиля и использования.
