Understanding Key Machinery Components:
Hydraulic Oil Temperature Sensor (液压油温传感器 - Датчик температуры гидравлического масла): This sensor measures the temperature of the hydraulic oil in the excavator's system. It's often located in the hydraulic tank or lines. An example is the hydraulic oil temperature sensor used in the XCMG XE370CA excavator.
Pilot Oil Filter (先导油滤 - Пилотный масляный фильтр): This filter removes contaminants from the pilot oil, which controls the hydraulic valves. It is usually situated in the pilot hydraulic system. For instance, the pilot oil filter in the XCMG XE215SA excavator.
Brake Pressure Sensor (制动压力传感器 - Датчик давления тормоза): This sensor monitors the pressure in the braking system of the excavator. It's typically found near the brake cylinders or lines. Example: brake pressure sensor in the XCMG XE700D excavator.
Transmission Pressure Sensor (变速箱压力传感器 - Датчик давления трансмиссии): This sensor monitors the oil pressure within the excavator's transmission system, crucial for gear shifting. Commonly found on the transmission housing. Example: transmission pressure sensor in the XCMG XE150W wheeled excavator.
Engine Water Temperature Sensor (发动机水温传感器 - Датчик температуры воды в двигателе): This sensor measures the temperature of the engine coolant. It is usually located in the engine block or coolant lines. For example, the engine water temperature sensor in the XCMG XE490DK excavator.
Fuel Oil Level Sensor (燃油油位传感器 - Датчик уровня топлива): This sensor measures the amount of fuel in the excavator's fuel tank. It is located inside the fuel tank. Example: fuel oil level sensor in the XCMG XE900C excavator.
Air Filter (空气滤清器 - Воздушный фильтр): This filter cleans the air entering the engine, preventing dust and debris from causing damage. XCMG excavators often have primary and secondary air filters (空滤1 - воздушный фильтр 1, 空滤2 - воздушный фильтр 2), located in the engine compartment. Example: air filter in the XCMG XE500HB excavator.
Water Separator (油水分离器 - Сепаратор воды и масла): This device separates water from the fuel, preventing corrosion and damage to the engine. XCMG excavators may have one or more water separators (油水分离器1 - сепаратор воды и масла 1, 油水分离器2 - сепаратор воды и масла 2), typically located in the fuel line between the fuel tank and the fuel filter. Example: water separator in the XCMG XE135 excavator.
Battery (电瓶 - Аккумулятор): The battery provides electrical power to start the engine and run the excavator's electrical systems. Located in the excavator's electrical compartment. Example: battery in the XCMG XE265C excavator.
Centralized Lubrication System (集中润滑系统 - Централизованная система смазки): This system automatically lubricates various parts of the excavator at regular intervals, reducing manual maintenance. The system includes a pump and lubrication lines distributed throughout the machine, such as in the XCMG XE335DK excavator.
