A hydraulic power plant is an assembly for generating hydraulic power from a source of electrical or fuel energy. This system is the result of the addition of numerous components that make it functional while meeting the environmental and safety standards imposed.

The example below shows a typical hydraulic system that allows you to understand the principle of operation of the main components installed on a plant (pumps, distributors, filters, and accumulator).  

Electrical level

The electrical level is part of the safety of the system. It allows us to know the level of oil present in the tank.

Filtre air

Filtration is an essential element of any hydraulic plant, for it to operate in the best conditions. Filtration also makes it possible to perpetuate the system and therefore to increase its lifetime.

The purpose of the air filter is to remove particles from the ambient air in order to avoid fouling and deterioration of the system.

Return filter

Filtration is an essential element of any hydraulic plant, for it to operate in the best conditions. Filtration also makes it possible to perpetuate the system and therefore to increase its lifetime.

Return

Added to the return filter, you will find a visual / electrical clogging indicator.

Oil tank

The volume of the oil tank can be standard or adapted to the client's application in the case of a large or very precise format.

There is also :

  • A visiting flap
  • A visual level
  • A filling coupler (avoids pollution)
  • A draining coupler (avoids pollution)
Cooling system

When the system is used intensively (rolling, under long-term pressure), the oil heats up and loses its desired properties. The oil cooling system keeps it at the temperature where its characteristics are the best - between 40 and 45 ° C.

Two types of cooling are commonly used: water / oil cooling or an air / oil cooler.

Technical file

Secofluid provides a complete technical file when delivered from the plant.

This file is composed :

  • of an identification number
  • a hydraulic diagram
  • an electrical diagram
  • precise categories
  • a list of spare parts
  • complete documentation on the list of components
  • a commissioning process
  • system maintenance assistance
Pressure filter

Filtration is an essential element of any hydraulic plant, for it to operate in the best conditions. Filtration also makes it possible to perpetuate the system and therefore to increase its lifetime.

Pressure

Added to the pressure filter, you will find a visual / electrical clogging indicator.

Function Block

The function block is the heart of the system. Its design and manufacturing are performed by Secofluid, or by following the diagrams provided by the customer or following a comprehensive study of the process to be achieved.

Standard elements are found in the function block :

  • Standard distribution (all or nothing)
  • Logical system
  • Pressure / flow control system
  • Proportional distribution
Accumulator + safety block

All systems with one or more accumulators are equipped with a safety block. These blocks make it possible to avoid leaving tanks under pressure when the system is shut down and thus avoids accidents during maintenance.

Accumulator

The Rexroth - Bosch Group range extends from a few centilitres to several hundred litres.

Instrumentation

This option lets you find out the important variables of the system in real time.

Instrumentation

You have information about:

  • the pressure
  • the flow
  • the temperature
Temperature control

The temperature control is achieved by a thermostat and a control rod.

Working with the cooling system, the oil can be raised or lowered to the desired temperature to operate under the optimum conditions of the application requested by the customer.

Groupe moto pompe")?>

The engine pump unit is the heart of the plant. It consists of an engine, a transmission and a pump.

Engine

You can use any type of engine on a system (electric or petrol / diesel)
