Caterpillar is one of the world's leading manufacturers of construction and construction machinery, and its hydraulic components are widely used in all types of machinery and equipment. Here are some common Caterpillar hydraulic parts:
1. Hydraulic pump: It is the power source of the hydraulic system, which converts mechanical energy into hydraulic energy and provides pressure oil for the system. Caterpillar's hydraulic pumps are available in a variety of types, such as axial piston pumps, which are characterized by high pressure, high flow and high efficiency to meet the needs of different equipment and operating conditions.
2. Hydraulic valves: It can be divided into three categories: directional valves, pressure valves and flow valves, which are used to control the pressure, flow and direction of the hydraulic system. For example, the relief valve can control the hydraulic system to maintain a constant state when the set pressure is reached, which is used for overload protection; The pressure reducing valve can control the branch circuit to obtain a stable pressure lower than the oil pressure of the main circuit; The reversing valve can change the flow direction of the hydraulic oil, so that the actuator can move in different directions.
3. Hydraulic cylinder: converts hydraulic energy into mechanical energy to achieve linear reciprocating motion or swing. Caterpillar's hydraulic cylinders come in different sizes and models and can be used to push, pull or support work devices such as boom cylinders, stick cylinders, bucket cylinders for excavators, etc.
4. Hydraulic motor: converts hydraulic energy into rotating mechanical energy to drive the rotating parts of the equipment. Caterpillar's hydraulic motors are used in some machinery that requires rotary motion, such as the slewing mechanism of a crane and the mixing drum of a mixer truck.
5. Hydraulic hoses and fittings: used to connect various components in the hydraulic system and convey hydraulic oil. Caterpillar's hydraulic hoses have good pressure resistance, wear resistance and flexibility, and the sealing and reliability of the joints are also high to ensure the normal operation of the hydraulic system and can adapt to a variety of complex working environments.
6. Hydraulic filter element: installed in the hydraulic system, it is used to filter impurities in the hydraulic oil, maintain the cleanliness of the oil, prevent the wear and damage of impurities to the hydraulic components, so as to prolong the service life of the hydraulic system.
