A hydraulic manifold is usually responsible for regulating fluid flow between more than one pumps and actuator and several other components throughout the typical hydraulic system.

This is equated to a switchboard in the regular or day-to-day electrical circuit since it gives you as the operator to manipulate the volume of fluid flowing involving the various aspects of your hydraulic machinery or equipment.

A practical application is a backhoe loader, in which a manifold can turn on and off to divert the flow of fluids on the telescopic arms of the back and front buckets.

The operator’s cabin may constitute the cause of connecting the manifold to the levers in order to be familiar with attain the right manifold behaviour.

Assorted hydraulic valves interconnected together could also form a manifold. Within a manifold, complex control behaviour is enabled from the multiple mixtures of various states of the valves.

How a Hydraulic Manifold Functions or Works

The most basic objective of a hydraulic manifold is always to distribute hydraulic oil in a given circuit. Hydraulic valves distributed through the entire manifold usually regulate the flow and distribution of pressurised oil, that’s channeled through hoses of a particular work device, with a hydraulic cylinder or motor.

Aside from the organised and logical layout supplied by a manifold, it can also help to consolidate components within itself to minimise space. Other advantages include pressure drop, less assembly time needed, fewer fittings required and minimised leak points. A hydraulic manifold could be equated to a black box, in which troubleshooting could be a concern. However, a correctly designed system with test point in strategic or key locations, locating or identifying the situation could be a lot easier or faster. Connecting a transducer to such test points, it will become simple to link the data on the machine PLC as well as display them using the HMI.

Application

Hydraulic manifold applications typically include material handling/ production equipment, machine tools, food processing, heavy construction equipment, off-highway equipment, farm equipment, oil field equipment, valve operations, plus more.
Manifolds appear in two basic designs: mono-block and modular-block designs. The first kind holds passages in addition to valves for the whole system whereas the latter supports a few valves, with interconnecting passages for the relevant valves and flow-through provisions.

To constitute a whole system, a modular block is generally linked to a few other modular blocks.

Conclusion

As there are countless configurations application for the manifold design, the engineer has several software products at his / her disposal to aid in designing a process. Advances of these packages and technology have enhanced the operation and treating hydraulic manifolds.
