What is Flushing? A Step-by-Step Guide to Hydraulic System Cleaning
Flushing is one of the most critical maintenance steps for hydraulic systems to operate long-lasting, efficiently and safely . So what is flushing, why is it so important, and how is it done? In this article, we will provide clear and practical answers to these questions.
What is Flushing?
Flushing is the process of cleaning pollutants such as dirt, particles, metal shavings, oil residues accumulated in hydraulic system pipes, hoses and componentswith high flow flow.
Flushing process; It is applied when the system is first installed, after maintenance or after revisions.
Why Flushing?
Cleaning the dirt that occurs after installation
Preventing premature failure of the system
To ensure the cleanliness of the oil and extend the life of the filter
Achieving ISO 4406 cleanliness class
Remember: The factor that most affects the life of a hydraulic system is oil cleanliness.
How to Do Flushing Step by Step?
Preparation
Components in the system are bypassed
A temporary flushing unit is installed at the appropriate flow rate
Set an ISO cleaning target (for example: ISO 4406 18/16/13)
High Flow Circulation
Hydraulic oil is circulated through the system at high speed
Goal: to remove dirt by providing turbulent flow
Filtration and Sampling
The oil is constantly cleaned by passing it through filters
The level of cleanliness is measured by taking samples at regular intervals
Termination
When the ISO cleaning value reaches the target, the process is terminated
System components are commissioned and tested
Things to Consider When Flushing
Appropriate filter micronage should be used (usually less than 10 microns)
Oil temperature should be checked (according to viscosity)
Flow rate-to-diameter ratio should be carefully adjusted
A cleaning analyzer should be used (such as an online particle counter)
What Do We Offer As Hidroman?
Hidroman handles flushing operations in industrial facilities:
Certified technical team
ISO 4406 analytical reporting
It is carried out in the field with mobile flushing units.
The flushing process keeps the heart of the hydraulic system clean. Once neglected, every single valve, cylinder and pump in the system is reminded of this negligence — as a malfunction.
