Introduction

As a key technology in the development and production of hydraulic components and hydraulic systems, hydraulic transmission measurement technology is an important tool for verifying product performance indicators and reliability. important means of sex, lifespan, etc. Only through quantification can the performance characteristics of hydraulic components and systems provide a basis for action or decision-making. GB/T 28782 "Hydraulic Transmission Measurement Technology" aims to unify the measurement technology in hydraulic transmission and consists of two parts. constitute. ---Part 1.General principles. The purpose is to identify general guidelines for measuring hydraulic component performance parameters under static or steady-state operating conditions. ---Part 2.Measurement of average steady-state pressure in closed circuits. The purpose is to determine the average steady-state pressure in the hydraulic transmission circuit program of. Hydraulic transmission measurement technology Part 1.General principles

1 Scope

This document specifies general guidelines for measuring performance parameters of hydraulic components under static or steady-state operating conditions. This document gives the sources and principles for the assessment of uncertainties in the calibration and measurement of systems containing hydraulic components. This document is suitable for assessing actual requirements and uncertainties of measurement system capabilities, or for establishing a system that meets target uncertainties.
