Hydraulic parts


Hydraulic parts are an important part of the hydraulic system, and they can be divided into several categories according to their function and use, including but not limited to the following:

1. Power components: such as hydraulic pumps (such as gear pumps, vane pumps, piston pumps, screw pumps, etc.), whose role is to convert mechanical energy into hydraulic energy and provide power for the hydraulic system.

2. Actuator:

Hydraulic cylinders: such as piston hydraulic cylinders, plunger hydraulic cylinders, etc., convert the hydraulic energy of the liquid into mechanical energy, so that the piston produces linear motion in the cylinder.

Hydraulic motors: such as geared hydraulic motors, vane hydraulic motors, etc., which are commonly used in applications such as driving rotating equipment, turning wheels or gears, etc.

3. Control elements:

Directional control valves: such as check valves, reversing valves, etc., which are used to control the flow direction of fluids in the hydraulic system.

Pressure control valves: such as relief valves, pressure reducing valves, sequential valves, pressure relays, etc., which are used to control pressure in hydraulic systems.

Flow control valves: such as throttle valves, speed control valves, diverter valves, etc., which are used to control the flow in the hydraulic system.

4. Auxiliary components: such as accumulators, filters (hydraulic filter box is one of them), coolers, heaters, oil pipes, pipe joints, oil tanks, pressure gauges, flow meters, sealing devices, etc., these components provide necessary support and protection for the normal operation of the hydraulic system.


To ensure the safety of hydraulic parts in operation, there are several key steps and principles that can be followed:

1. Choose high-quality hydraulic parts: Use high-quality hydraulic parts from reliable manufacturers, which often have higher durability and reliability. Avoid low-quality or non-certified parts, as they may increase the risk of breakdowns and safety hazards.

2. Correct installation and commissioning: Ensure that the hydraulic parts are properly installed and debugged in accordance with the manufacturer's instructions and installation guidelines. Improper installation or commissioning can lead to performance issues or safety hazards.

3. Regular inspection and maintenance: Regularly check the status of hydraulic parts, including checking the leakage of oil, the fastening of each connection joint and pipeline, the normal operation of valves and pumps, etc. Replace worn or damaged parts in a timely manner, and clean and replace fluids to keep the system clean and functioning properly.

4. Set up safety valves and relief valves: Set appropriate safety valves and relief valves in the hydraulic system to avoid overpressure and overload of the system. The selection of these valves should be determined based on the system's pressure rating, flow rate, and operating conditions, and require regular inspection and maintenance to ensure they are working properly.

5. Provide necessary protective measures: When operating hydraulic equipment and systems, necessary protective measures should be provided, such as setting up protective fences to avoid personnel from contacting moving mechanical parts. Operators should wear appropriate safety protective equipment, such as helmets, protective glasses, earplugs, etc.

6. Follow the correct operating procedures: When operating hydraulic equipment and systems, the correct operating procedures must be followed. This includes understanding how the system works, operating procedures and emergency measures, and following relevant safety regulations and standards.


Use high-quality hydraulic oils: Choose the right hydraulic oil for your hydraulic system and ensure its quality and cleanliness. The use of low-quality or contaminated hydraulic fluids can lead to degraded system performance and safety hazards.
