Three Points on Understanding Hydraulic Valves

Hydraulic valves are an important part of machines and certain equipments. If you do not work with these valves on a daily basis, you may not understand the importance of the hydraulic valve, the way it operates, and the different parts involved in the process of a working valve.

Point 1: The Functions of the Hydraulic Valve

Hydraulic valves are responsible for directing the flow of fluids beginning from the input port of the valve and coming through the output port. The commonly used fluid is oil. The spool position inside of the valve determines the direction that the fluids flow through the valve. The force of the fluids flowing through the valve is driven by a force motor.

Point 2: The Specific Parts of the Hydraulic Valve

Hydraulic valves have three specific parts that are included along with the valve in order to create the right amount of pressure to allow the fluids to flow quickly, powerfully, and easily. Below are the parts and their primary function:

  • Power Conversion: this part gives isolation between the power valve, external field bus, and the auxiliary supplies. It is also the source of voltages to regulate functional blocks that may occur while the valve is at work.
  • Field Bus Interface and Control: this part gives isolation between the control system and the signals that come from the field bus. The control system turns all information coming from the field bus into instructions for the DSP.
  • Valve Control: this part takes a role in positioning the spool and measuring temperature and pressure. This part is also responsible for indicating certain alarm conditions.

Point 3: The Primary Uses for Hydraulic Valves

The hydraulic valve is a necessity for carrying out certain hydraulic mechanisms. Most typically, hydraulic valves are used in machinery and equipment that lifts heavy objects. But hydraulic valves are also present in heavy machinery, like vehicles, military machinery, and aircraft. If you work on a construction site, in a manufacturing facility, or do everyday normal activities like drive a car, you are most likely using some type of hydraulic valve.

Hydraulic valves are an essential part of major tools, machines, and equipment. The valves are responsible for transporting fluids from one end of the valve to the other. It gives off high pressures and power which makes it powerful enough to manage its role in big machinery and equipment.


Important Facts about Hydraulic Pumps

Hydraulic pumps are an essential part of some of the major machinery and equipment that are used to complete vast and complicated tasks. If you have ever worked with construction, manufacturing, or industrial equipment, chances are high that you were using some kind of hydraulic pump. Keep reading for more information on the pumps.

How Hydraulic Pumps Work

The hydraulic pump is a simple machine, but it achieves the highest levels of pressure when compared to other pumps. Speaking in general terms, the pump takes mechanical energy and turns it into hydraulic energy. Hydraulic pumps apply pressure to hydraulic liquids and initiate the process of positive displacement. Positive displacement includes the expansion and contraction of the cavities inside of the pump. The liquid inside of the cavities are then allowed to leave the pump at a high pressure level. Although there are other pumps that have similar operations, the hydraulic pump is one of the most preferred.

Primary Uses for Hydraulic Pumps

Hydraulic pumps are used for creating very high fluid pressures in order to work efficiently. With that being said, these pumps are typically included in high-powered equipment, such as construction machinery (forklifts, scissor lifts, back hoes), manufacturing equipment, industrial machinery, and elevators.

There are also a variety of pumps. Your use of the pump will determine which kind of hydraulic pump you will need. You may be in need of a gear pump, which is the simplest form of the hydraulic pump. Rotary vane pumps have more power than gear pumps, but are typically used for medium pressures. Screw pumps are typically used at low pressures for high level flows. Radial piston pumps are used for smaller sized flows at high pressures.

Choosing the Right Hydraulic Pump

Hydraulic pumps come in all different varieties. To determine what pump you will need, there are some determining factors you must first figure out. The most common factors are figuring out the needed pressure, the flow rate of the fluids, the power of the pump, efficiency numbers, and the temperature needed for operation.

Hydraulic pumps are essential to carry out specific functions that include moving fluids at high pressures. If you need to use a hydraulic pump, it is important to know what pump you need and the specifications you should meet with the pump.
