What is an oil hydraulic pump
The hydraulic pump
In this article, we will delve deeper into how hydraulics work, because today we are talking about information about the most important component of a hydraulic system: the hydraulic or hydraulic pump. How does it work, what does it cost and how long can it be used? We will take a closer look at all of these questions here.
How does a hydraulic pump work?
The hydraulic pump is the heart of all hydraulic systems - without it, no oil can be pumped and therefore no hydraulic system can get going. There are a large number of designs that consist of different components, can generate a smaller or larger volume flow and different amounts of pressure.
The functional principle is always the same: every hydraulic pump works according to the Displacement principle. The pump sucks the hydraulic fluid, usually a specific hydraulic oil, from a tank through a suction connection and feeds it into the circuit of our hydraulic system. Here the oil is transported through a filter from the inlet side of the pump to the outlet side of the pump.
Different pumps and applications in hydraulics
There is a large number of different pumps for different systems, with variations in speed, direction of rotation and in the suction connection. A basic distinction is made between three types of hydraulic system: On the one hand, we have that Vane pumps and Gear pumps and on the other hand the Piston pumps.
Vane pumps, which are also called rotary vane pumps, have one adjustable funding volume, a low volume flow pulsation in their circuit and are comparatively up for grabs Cheap.
They get a minus point, because they have a high susceptibility to wear and pressure up to maximum 300 bar can generate. Vane pumps are mainly found in the automotive sector, such as in power steering systems.
In gear pumps, the volume of hydraulic fluid that is displaced is very constant. Gear pumps thus convey the hydraulic oil very evenly and are capable of printing up to 300 bar to create. Similar to the vane pump, this pump is often used for drives in automotive engineering.
An external gear pump
With a piston pump, very high pressure can be built up, and it is also possible to precisely meter the delivery rate. Piston pumps are generally used to move particularly heavy loads and machines. You can pressures from up to 1000 bar produce.
The piston pumps include the Axial piston pumps, the Radial piston pumps and the Reciprocating pumps. The axial piston pump is insensitive to dirt and is also suitable for use with changing pressure conditions. Just like vane pumps, piston pumps are available with constant and also with adjustable displacement.
Price info: What does a hydraulic pump cost?
The answer to the question of what a hydraulic pump costs is: it depends. Hydraulic drives and thus hydraulic pumps are a dime a dozen. Well, maybe not quite in this number - but they are everywhere and, as we have already seen, in different designs, strengths and sizes.
A small hydraulic pump, such as that found in the power steering of our car, for example, costs between 50 and 500 euros. A larger hydraulic pump, such as that used in excavators and construction machinery, costs around 1,100 to 4,000 euros. A hydraulic pump that generates up to 700 bar and has a tank volume of 30 liters costs around 4,000 euros. The more powerful the pump should be, the higher the associated costs.
How long can a pump be used?
Basically you can say that all hydraulic pumps have a very long service life are. With appropriate maintenance of the various components, the oil connections, filters and the tank, they work very reliably for many hours and years. Of course, the longevity also depends on the type of pump and the duration of the load.
As you saw, that is Use of hydraulic pumps omnipresent - the choice of the right pump primarily depends on the purpose for which you need hydraulic power and how much load you want to move. There are a number of suppliers of hydraulic products, both for new and used pumps, as well as for the maintenance of your system. We recommend you to do this Paying attention to quality and getting individual advice.
We would be pleased if we were able to help you with this information and tips and wish you a successful (hydraulic) drive!
