Test method for Determination of noise emitted by hydraulic pumps

The test method Determination of noise emitted by hydraulic pumpsprovides useful information to determine priority measures for noise control and production – effective product improvement.

Overview of the test method Determination of noise emitted by hydraulic pumps

Test method name: Determination of noise emitted by hydraulic pumps

Test method: ISO 4412-1:1991 Hydraulic fluid power – Test code for determination of airborne noise levels – Part 1: Pumps [1].

Performed at: Absorption Room, DASM Institute of Acoustic Materials Development & Application

1. Objectives and test objects

– Test objectives

Determine the airborne noise level of hydraulic pumps.

– Test object

Hydraulic pumps

– Explanation and description of hydraulic pumps

A hydraulic pump is a component in a hydraulic transmission system (used in construction machinery/machine tools/motor vehicles, ships, etc.) that converts the mechanical energy of the driving engine into pressure energy of the fluid flow (hydraulic oil) supplied to actuators/mechanisms.

A hydraulic system includes a power supply source (pump), actuators (cylinders or motors), control, adjustment, and protection mechanisms to protect the system from overload. In complex systems, there may be multiple pumps, multiple actuators, and control and adjustment mechanisms to govern the movement law of the engine.

In the test list, test 39 (ISO 4412-2:1999) refers to the determination of noise emitted by hydraulic motors.

2. Experimental procedure

Steps to perform:

• Equip fully with devices, microphones, and measurement samples.
• Perform sample measurement.
• Process and report results

Role – importance of the test method Determination of noise emitted by hydraulic pumps

The test method Determination of noise emitted by hydraulic pumps conducted by the DASM Institute of Acoustic Materials Development & Application helps provide useful information, meeting all practical needs of customers and businesses wishing to:

• Control noise, prevent noise, insulate the noise source, and implement mitigation measures to avoid health and safety risks and avoid negative impacts on the surrounding environment.
• Measure the working environment and assign appropriate job tasks. Train workers exposed to noisy environments to understand the hazards of noise and safe working measures.
• Control equipment status, early detect signs and causes of damage, etc., to proactively maintain machinery.
• Material manufacturers, consulting – design units, etc., of hydraulic pumps wanting to achieve effective noise reduction, sound absorption, sound insulation, etc.
• Help control quality during production, optimize research and development of products and materials to reduce noise, soundproof, absorb sound, sound insulate, etc., related to noise emitted by hydraulic pumps.
• Commercial businesses/consultants have a authentic basis to propose and implement solutions prioritizing machinery, equipment, technical and technological initiatives that can mitigate noise impact.
• Support legal disputes, lawsuits, expert appraisals, and environmental sample measurement and analysis in case of noise violations exceeding environmental technical regulations.

At the same time, DASM will carry out consulting and design work to create shape/structure/material solutions to efficiently and economically refine customers' test samples (in case they do not meet standards yet).

If previously you had concerns and worries and had to pay many fees for similar activities abroad, now you just need to contact DASM. The entire remaining process will be proactively implemented by us in the fastest time to complete the customer experience about us: DASM provides acoustic consulting services with truly superior quality, the most competitive prices in the industry, and attentive, dedicated customer care policies.
