Importance of Breathers in Excavators

In hydraulic systems, like those found in excavators, hydraulic tank breathers are crucial for allowing air to enter and exit the hydraulic reservoir as fluid levels change. This prevents vacuum formation and over-pressurization, ensuring the smooth operation of hydraulic components. Installation is typically on top of the hydraulic tank. For example, the 198-60-55510 breather is designed for PC200-8 and PC400-7 excavators.

Engine breathers, on the other hand, manage pressure within the engine's crankcase by releasing gases. This is important for preventing oil leaks and ensuring optimal engine performance. The engine breather is usually located on the valve cover or crankcase of the engine. The 298-4547 serves as an engine breather valve cover cap for the E320D2 C7.1 engine.

В гидравлических системах, таких как экскаваторы, сапуны гидравлического бака необходимы для обеспечения входа и выхода воздуха из гидравлического резервуара по мере изменения уровня жидкости. Это предотвращает образование вакуума и избыточное давление, обеспечивая плавную работу гидравлических компонентов. Установка обычно производится на верхней части гидравлического бака. Например, сапун 198-60-55510 предназначен для экскаваторов PC200-8 и PC400-7.

Двигательные сапуны, с другой стороны, регулируют давление внутри картера двигателя, выпуская газы. Это важно для предотвращения утечек масла и обеспечения оптимальной работы двигателя. Двигательный сапун обычно располагается на крышке клапанов или картере двигателя. 298-4547 служит крышкой сапуна двигателя для двигателя E320D2 C7.1.

在挖掘机等液压系统中，液压油箱通气阀对于允许空气随着液位的变化进入和排出液压油箱至关重要。这可以防止形成真空和压力过高，确保液压部件的平稳运行。安装通常在液压油箱顶部。例如，198-60-55510 通气阀专为 PC200-8 和 PC400-7 挖掘机设计。

发动机通气阀则通过释放气体来管理发动机曲轴箱内的压力。这对于防止油泄漏和确保最佳发动机性能非常重要。发动机通气阀通常位于发动机的气门盖或曲轴箱上。298-4547 用作 E320D2 C7.1 发动机的发动机通气阀盖帽。
