Introduction

In hydraulic systems, power is transmitted and controlled through pressurized fluid in a closed circuit.

The oil block assembly for use in a hydraulic system consists of components mounted on its surface or inserts that are inserted therein. In the oil block

There is no need for a tubing connection between the components. Complete and accurate identification of components and connections facilitates the installation and maintenance of the oil block.

The system supplier should provide the identification of the fuel block and record it in the file. The fuel block manufacturer is required to meet the requirements in the supplier contract.

Hydraulic transmission oil block assembly and its component identification

1 Scope

This standard specifies the marking criteria for the oil block and component mounting elements (such as mounting surfaces or insert holes) in the hydraulic system, including

Identification code on the fuel block associated with the service documents (such as oil maps, bills of materials, and assembly drawings). Define only by mounting surface or insert hole

One identification code for the assembly, installation, use and maintenance of the oil block assembly.
