Introduction

In a hydraulic system, power is transmitted and controlled by means of pressurized fluid in a closed circuit. The initial cleanliness of a hydraulic system can affect its performance and service life. Contaminants introduced by manufacturing and assembly can be Circulate in the system and cause damage. In order to avoid this damage, the hydraulic system oil and inner surface must be filtered and cleaned to achieve the required cleanliness. Spend. This document describes the use of filters to clean hydraulic systems after assembly, but this method does not replace Prior to assembly, use other methods that better enable the system to achieve and maintain the target cleanliness. hydraulic transmission system Cleaning procedures and cleanliness inspection methods

1 Scope

The methods described in this document apply to. a) Inspection of oil pollution degree of hydraulic system assembly; b) Verification of the target cleanliness of the hydraulic system before leaving the factory; c) If necessary, purging the hydraulic system to target cleanliness. The cleaning steps specified in this document are not intended to replace a suitable system cleaning procedure, see ISO 23309 for system cleaning procedures. hydraulic Parts and components used in the system should be cleaned before assembly, see ISO 18413 for guidelines.
