In this article, we will talk about the Hydraulic System Components. We will look at the different types and their functions. We will also discuss how to maintain and repair them. After reading this article, you should be able to identify all the parts of the system. Let us begin! Let us begin by defining what each component is. What are its functions? What are its types? And what are their maintenance requirements?
Symbols
Among the most requested topics in the fluid power community, hydraulic system symbols can be a little intimidating for beginners. The good news is that learning how to read a schematic with more than three symbols will not take advanced CAD skills. However, you should at least understand why each symbol is used in a circuit. It is difficult to explain the use of these symbols without a working knowledge of the field, so here are a few basic tips to help you understand them.
Lines on a hydraulic schematic typically represent hoses, tubes, or pipes. They often cross one another. To differentiate these lines on the drawing from the actual machine, look for a node or dot at the intersections. Also, if two lines cross each other in a schematic, they should be labeled as such. While a curved arrow indicates rotation, a diagonal arrow denotes variable components. A cartridge valve, also called a logic valve, is another popular symbol. This valve features a large “T” shape in the center, a poppet and a spring above it.
The pressure reducing valve is the only normally-open pressure valve in hydraulics. It is similar to the relief valve symbol but flows in a neutral state. This valve receives its pilot signal from the pressure downstream of the valve. The pressure downstream must rise above the spring setting value before the valve closes. The hydraulic cylinder then closes, preventing incoming pressure from reaching the downstream path, and allowing the pressure to decelerate back to the pressure setting.
A pump is a basic unit in a hydraulic system. It converts mechanical energy into hydraulic energy through an auxiliary mechanism. It connects to a double-acting cylinder through two transmission lines. In this way, the pump can control the pressure.
Functions
There are many hydraulic system components, but they all have the same basic functions. These components include a hydraulic pump, a reservoir for the hydraulic fluid, and a directional control valve or flow control valve. These components work together to channel the fluid throughout the aircraft. They are crucial for many different types of applications. Here, we’ll take a look at some of the most common hydraulic system components and their functions.
The hydraulic actuator is a component that converts pressure energy into mechanical energy, powering the pistons in hydraulic cylinders. The hydraulic actuator can be either a rotary or linear actuator. The linear actuator gives force outputs in a straight line, while a rotary actuator, also known as a reciprocating motor, produces torque or rotational motion. The hydraulic valve controls the operation of both types of actuators.
Other parts of hydraulic systems include a flow control system, travel limit control, electric motor starters, and overload protection. Hopefully, this article has helped you understand how hydraulic system components work.
Cylinders come in a variety of styles. A Rotary Cylinder is used for applications that require a circular motion. A Vane-Type Cylinder is another type, using a rotating vane in a circular housing to produce a rotary motion. There are three main types of hydraulic valves, and each one has a specific function. The Vane-Type Cylinder is the most common type and is used in hydraulic systems.
Fluid reservoirs store hydraulic fluid and prevent overfilling. They control heat transfer, manage initial force, and separate air and moisture from the fluid. These are also necessary for high-altitude applications. They can store a significant amount of hydraulic fluid, and can be expensive and require extensive maintenance. The fluid reservoirs can become clogged with air, so a quality hydraulic oil reservoir is an essential part of a well-designed hydraulic system.

Types
There are several types of hydraulic system components. The most basic is a pressure relief valve. It limits the system pressure to a predetermined range and automatically closes when the pressure exceeds the limit. In order to prevent the hydraulic system from leaking, pressure relief valves are often located near the pump. They divert the flow back to the tank. One type of pressure relief valve consists of a poppet held in place by a spring force. The fluid enters the valve through the opposite side. When the pressure rises above a set value, the valve opens and diverts the pump’s flow to the tank.
Another type of hydraulic system component is the directional control valve. This valve opens and closes passageways and directs fluid to actuators. This type of valve is commonly available to machine operators. It also allows different parts of a larger machine to be used at different times. Its ‘way’ refers to how many ports are available. These valves can control the speed of the fluid flow by opening or closing. There are two types of valves: check valves and non-return valves.
Another type of hydraulic system component is the hydraulic actuator. These are devices that convert pressure energy into mechanical motion. They can be linear or rotary. A linear actuator produces force outputs in a straight line, while a rotary one produces torque or a rotating motion. Both types are controlled by hydraulic valves. It is possible to use a combination of both types of pumps. However, the types of hydraulic system components vary depending on the purpose of the hydraulic system.
The hydraulic system is based on Pascal’s law, which states that pressure in a fluid enclosed within a chamber is uniform and proportional in all directions. Therefore, a piston with a smaller cross section will feel much less force than one with a larger. The same principle applies to hydraulic actuators. They are also more rugged than other types of actuators, and are able to function at high pressures without pumping.
Maintenance
Proper maintenance of hydraulic systems requires thorough knowledge of the components, fluid flow paths, and functions. Besides, proper maintenance and inspection of hydraulic systems is essential to keep the equipment running smoothly and at optimal levels. Here are some tips to follow:
Ensure regular maintenance of all hydraulic system components. Check the hoses and fittings for leakage. If metal lines are used, look for any damage or loose anchorage. Also, inspect the hoses for kinks and scratches. Tighten them accordingly. Moreover, keep the hoses secure so that they don’t chafe against each other. You should also ensure that they are free of dirt and debris.
The fluid should match the instruction plate on the aircraft hydraulic unit. It must be kept free of dirt and debris, as these particles can damage the seals and corrode the hydraulic unit. If the fluid is suspect, do not use it. In addition, avoid leaving the container open to the environment. Mineral-based fluids are highly flammable. Always use proper hydraulic fluid. It can be obtained from the manufacturer. You can also buy hydraulic fluid from a local hardware store.
Ensure the condition of hydraulic fluid is good by checking for cavitation. This condition can cause the system to shut down. Check the fluid level and clean the filter. If there are traces of contaminants, check for leaking fluid and flush the filters thoroughly. In addition, follow the manufacturer’s guidelines for cleaning system filters. The Quick Reference Handbook and ECAM checklists will assist in recovering the system when necessary. These checklists will make sure that you’re getting the best care of the system.
Proper maintenance of hydraulic system components is necessary to avoid major complications. Fluid leaks, overheating, and other issues can occur if contaminated fluids are present in the system. Incorrectly maintained hydraulic systems will lead to premature component failure. In addition, the components of the hydraulic system may be damaged if the fluid is improperly routed. This will cause increased stress and vibrations on the system. The best way to ensure that your hydraulic system is in peak condition is to regularly inspect its components and fluid levels.
