Hydraulic Couplings And Hydraulic Pumps

Hydraulic couplings

What is a hydraulic coupling?

A hydraulic coupling (also coupler) is a quick and convenient way to connect or remove hoses and fittings in high pressure hydraulic systems. They are supplied with a fluid seal to maximize the hydraulic system. The hydraulic coupling allows a flow of hydraulic fluid between the two closely connected tools. For example, a tractor operator can use hydraulic couplings to quickly switch between accessories such as grabbers and cutters on the same site. Whatever its application, hydraulic couplings provide a safe and convenient way to move between tools.

Types of hydraulic couplings

Pioneer couplings and face couplings are the two main types of hydraulic couplings.

The pioneer coupling has a male end and a female end. When inserted into the receptacle, the male end has a circular snap ring that is pushed back. Simply pull the collar back on the female end and plug in the male end. Pressure seals allow hydraulic fluid to move between connectors.

The flat face hydraulic coupling is similar to the pioneer coupling. It is very easy to operate. All you have to do is press the male and female ends together without pulling back the collar on the female end.

There are a variety of different sizes and shapes within these two categories. It is critical to ensure that your equipment is properly integrated with new machines that come with hydraulic couplings. All brands of hydraulic couplings will match each other according to ISO standards, but you cannot match different sizes.

Hydraulic pumps

What is a hydraulic pump?

 The hydraulic pump is a kind of mechanical power source used to convert mechanical power into hydraulic energy, such as pressure or flow in hydraulic drive systems and hydrostatic or fluid power systems. The pump produces a flow with sufficient power to overcome the forces caused by the load at the pump outlet. The pump is used in most heavy construction vehicles in hydraulic systems and is also used to power hydraulic tools such as hydraulic spreaders, jacks, hydraulic saws, nut splitters, cutting tools, presses, etc. The hydraulic pump components include three parts: coupling, hydraulic oil tank and oil filter.

Classification of hydraulic pumps

1. non-positive-displacement pumps

Centrifugal pumps, axial pumps, and radial pumps.

2. Positive-displacement pumps

Reciprocating pumps, rotary pumps.

3. Gear pumps

external gear pumps, lobe pumps, internal gear pumps, gerotor pumps, screw pumps, vane pumps, piston pumps, axial piston pumps, and radial piston pumps.

The difference between hydraulic pumps and hydraulic motors

Hydraulic pump transmission failure occurs when the hydraulic pump is connected to the prime mover through pulleys, sprockets and gears. While the hydraulic motor is connected to the load through pulleys, sprockets and gears, allowing its main shaft to withstand large radial loads.
