Hydraulic System Components

1. Hydraulic System Components Many hydraulic systems have a variety of pumps that may be manual, electric, or engine driven. Some use manual or electric pumps only on the ground, while others only use them during high-demand situations such as gear retraction or during high-speed operations. Regardless of the system, a pump is an important component in a hydraulic system. Here are some important considerations when choosing a pump for your hydraulic system. Fluid flow through a selector valve A hydraulic system has several types of flow control valves, all of which are used to control the fluid flow. These valves control the pressure of the system and allow various components to function. Some examples of these valves are selector valves, sequence valves, priority valves, shuttle valves, hydraulic fuses, and more. A selector valve controls the direction of movement of the hydraulic actuating cylinder and provides a path for the return of hydraulic fluid to the reservoir. In the first example, the fluid enters the actuator at one end and is blocked at the other. When the spool is moved to the right, the valve ports the outlet passage of the pump to passage "A." This allows fluid to flow from the pump to one side of the actuator. The fluid then passes through the valve and returns to the tank, and the procedure repeats. The fluid in view "A" is blocked when the motor swings down. Filters are used to remove foreign particles In order to ensure that your hydraulic system remains as efficient as possible, you must properly maintain and clean your filter. Foreign particles present in your hydraulic fluid may cause a number of problems in your system. Properly maintained filters will increase the mean time between component failures and ensure that your machine runs smoothly. This process will be illustrated by the flow chart

One micron is one millionth of a meter. A grain of salt is 100 microns. For comparison, a red blood cell is 40 microns in diameter. Even a single micron can cause significant damage to your hydraulic system. The proper filter will protect the most critical components of your machine. Directional control valve There are several types of directional control valves in a hydraulic system. The types include the ball, butterfly, needle, gate, and piston. These valves are usually electronically controlled, though some models may be operated manually. When activated, they allow fluid to flow through one side and close off the other. They can be used in any number of hydraulic applications, from hydraulic pumps to air compressors. Read on to learn more about this type of valve. A hydraulic system needs a directional control valve to control the flow of fluid. This fluid is so powerful that it can move mountains. However, it's not intelligent. It will pick the most direct route and face the least resistance. That's why a directional control valve is so important. This type of valve allows the operator to direct the fluid. Its benefits are numerous, including improved safety and increased productivity. Hydraulic actuator reservoir A hydraulic actuator reservoir is an important component of a hydraulic system. They serve a variety of purposes and are used to store the hydraulic fluid when not in use. The hydraulic actuator reservoir also acts as a means to control the amount of heat transferred and the initial force applied to a system. They are also used to separate air and moisture from the hydraulic fluid, preventing the fluid from becoming contaminated. The hydraulic actuator reservoir is often part of a machine's body. The fluid is provided to the actuator through a pump. This fluid is supplied to the actuator and is regulated by a pressure control valve. When pressure builds up in the system and there is no way for it to return to the reservoir, the fluid will be forced through a piston and actuating cylinder. Once the piston of the actuating cylinder moves, the fluid is directed back through the selector valve and through the reservoir to the pump.
