Converting Mechanical Energy Into Hydrostatic Energy

Converting Mechanical Energy Into Hydrostatic Energy

Hydraulic pumps are simply put, a machine that uses the principles of pressure to pump fluids in any necessary direction. Put in a more detailed way, the hydraulic pump creates a vacuum its inlet when it operates; this vacuum then forces any fluid found on its other side into the inlet. Mechanical action then pumps this liquid to the designated outlet and the hydraulic system. Hydraulic pumps are largely of two main subcategories as hydrostatic pumps and hydrodynamic pumps

There are many types of hydraulic pumps – popular examples include gear, rotary vane, bent axis, flow, pressure, etc.:

• Gear pumps – there are basic types of gears, with gear pumps being one of them (the other two are rotary vane and piston pumps). Even of these basic types, the gear pump is by far the most economical and simple option. Gear pumps consist of externally fit gear teeth, which upon meshing create pressure. Gear pumps used to be noisy, but newer models have become much quieter and reliable. Their reliability largely lies in how breakdowns in this type of pump is very rare, as the pump gradually wears down until it becomes unusable, instead of breaking down all of a sudden.

• Rotary vane pumps – when compared with gear pumps, rotary vane pumps are much more efficient. They are not used for high pressure systems usually, but newer models have become capable of handling pressures of over 30,000 kPa. Since this type of pump has the ability of changing the centre its body, rotary vane pumps make for simple and adjustable pumps which are easy to use.

• Hydraulic Split Flow pumps – the difference from normal hydraulic pumps is that these pumps specialize in having a number of outlets, hence the name. The “Split Flow” technology here refers to the ability of these pumps to synchronize movement and provide multiple functions without having the need to resort to multiple flow dividers. Basically, what this means is that you will not need to resort to using a number of hydraulic pumps, but instead rely on only pump for all your needs.

The uses of hydraulic pumps are not limited to any single field. They are used throughout the many industrial fields, such as those of construction, transport, mining and the like, for example. Under these fields, hydraulic pumps are applied to perform functions such as jacking alongside ToughLift jacking systems, clamping, drill rigs, presses, flushing rigs, lifting, etc.

Thus, it can be seen that hydraulic pumps have become an essential equipment in many different fields, and are widely used throughout the world nowadays.
