What are the common accessories for hydraulic accessories?

Hydraulic cylinder: As the actuator of the hydraulic system, the hydraulic cylinder receives high-pressure oil from the hydraulic pump and converts it into mechanical energy to drive the load for linear or rotational motion. According to different structures, hydraulic cylinders can be divided into piston type, plunger type and swing type, etc., and are widely used in various mechanical equipment, such as excavators, cranes, injection molding machines, etc., to achieve functions such as lifting, pushing, and clamping.
Hydraulic pump: The hydraulic pump is responsible for converting mechanical energy into hydraulic energy. Common types of hydraulic pumps include gear pumps, vane pumps and plunger pumps. Gear pumps have a simple structure and are suitable for low-pressure systems; vane pumps have higher efficiency and are suitable for medium-pressure systems; plunger pumps can provide extremely high pressure and flow, and are suitable for high-pressure and large-flow hydraulic systems.
Oil tank: The oil tank not only serves as a storage container for hydraulic oil, but also undertakes multiple functions such as heat dissipation, precipitation of impurities, and separation of gases. Reasonable oil tank design can ensure the cleanliness of hydraulic oil, temperature control and stable operation of the system. The inside of the oil tank is usually equipped with partitions, filters and cooling devices to optimize oil circulation and heat dissipation.
Oil pipes and pipe joints: Oil pipes are responsible for transmitting the high-pressure oil generated by the hydraulic pump to hydraulic cylinders, valves and other components. Their materials and connection methods need to be selected according to the working pressure, flow and working environment. Common oil pipe materials include rubber hoses, steel pipes and nylon pipes. Pipe joints are used to connect oil pipes and components to ensure the sealing and smoothness of the oil.
Filters: Filters are key components for keeping the hydraulic system clean. They can effectively remove solid particles, moisture and contaminants in the hydraulic oil to prevent these impurities from causing wear and failure to the system. The accuracy and type of the filter need to be selected according to system requirements.
Pressure gauges and pressure sensors: Pressure gauges are used to intuitively display the pressure value of the hydraulic system to help operators monitor the operating status of the system. With the development of technology, pressure sensors are also widely used. They can measure pressure more accurately and convert it into electrical signals, which is convenient for remote monitoring and fault diagnosis.
Flowmeters: Flowmeters are used to measure the flow of oil in hydraulic systems. They are important tools for monitoring the efficiency of hydraulic systems, detecting leaks and regulating flow. According to different measurement principles, flowmeters can be divided into vortex flowmeters, ultrasonic flowmeters, magnetic flowmeters and other types.
Valve: Valve is a control element in hydraulic system, used to regulate, distribute and guide the flow of oil. Common valves include reversing valve (used to change the flow direction of oil), relief valve (used to limit the maximum pressure of the system), throttle valve (used to regulate flow), sequence valve (used to control the flow of oil in sequence), etc. The correct selection and configuration of valves are crucial to improving system performance and realizing complex control logic.
