Highlight Installs Liquid Test Fatigue Test Bench After Preparing Hydraulic Oil for Pressure Fatigue Testing

Preparing the correct test medium is an essential part of installing a liquid pressure fatigue testing system. For this project, hydraulic oil was purchased and prepared before the Liquid Test Fatigue Test Bench was installed, supporting the next stage of equipment setup and operation.

The Liquid Test Fatigue Test Bench is a computer-controlled hydraulic pressure testing system designed for repeated pressurization and pressure pulse fatigue testing. It can use hydraulic oil or water as the test medium, automatically unload after reaching the set pressure, repeat pressure cycles, and stop with an alarm after reaching the preset number of tests.

What Is a Liquid Test Fatigue Test Bench?

A Essai en milieu liquide Banc d'essai de fatigue is pressure testing equipment designed to repeatedly apply liquid pressure according to configured test conditions.

The Highlight system uses a liquid-driven control system. Its pressure controller sets the pulse pressure. After the system reaches the set pressure, it automatically unloads and can then repeat the pressurization process to perform a cyclic test.

This makes the equipment different from a simple pressure source used only to reach and hold one pressure point. Its core purpose is repeated pressure cycling and fatigue testing under controlled conditions.

How Does the Hydraulic Pressure Fatigue Test System Work?

The working principle published for this fatigue test bench is straightforward.

The system uses hydraulic drive. Low-pressure oil or water enters the pressure system, and adjustment of the driving hydraulic source allows the system to produce higher-pressure oil or water. The pulse pressure is then controlled according to the test setting.

Once the specified pressure is reached, the system automatically unloads. It can then pressurize again, creating the repeated pressure cycle required for a pressure fatigue test or pressure pulse test.

The sequence can therefore be understood as:

Liquid Medium → Pressurization → Set Pressure → Automatic Unloading → Re-Pressurization → Repeated Cycles

The equipment automatically stops when the preset pulse count has been reached.

What Pressure Ranges Does the Liquid Test Fatigue Test Bench Support?

How Does the Pressure Pulse Test Cycle Work?

A major function of the equipment is repeated pressure pulse testing.

The operator can configure the test pressure, pulse number, and pulse frequency through the computer-controlled system. The pulse frequency can be set within the published range of 0.5–1 Hz.

Once the pressure controller reaches the configured pressure point, the system unloads automatically. The next cycle then begins. This allows the machine to perform repeated pressurization rather than requiring the operator to manually build and release pressure for every cycle.

The product specification states that the number of single cycles can be set up to 1 million times. When the configured number of tests has been reached, the equipment automatically stops and alarms.

Again, 1 million cycles is the equipment’s published capability, not the cycle count used during the installation shown here.

Why Does Computer Control Matter in a Fatigue Test Bench?

Repeated pressure cycling can involve a very large number of test cycles. Computer control reduces the amount of repetitive manual operation required during this process.

Le Essai en milieu liquide Banc d'essai de fatigue uses computer control, with software written in LabVIEW. The system allows the relevant test pressure, pulse count, and pulse frequency to be set.

Its published control functions include:

• setting the required test pressure;
• setting the pulse number;
• setting the pulse frequency;
• repeated automatic pressurization;
• automatic unloading after reaching pressure;
• automatic stopping when the test count is reached;
• alarm when the configured test count is completed.

These functions are particularly relevant when buyers are looking for an automatic pressure test system, hydraulic fatigue test bench, or pressure pulse testing equipment rather than a basic manually operated pressure source.

What Can Be Customized on This Pressure Testing Equipment?

The product is not limited to one fixed configuration.

One important published customization point is the number of test pieces that can be tested simultaneously. According to the product specification, this is designed according to customer requirements, and each test piece can be controlled separately.

This matters for industrial buyers because pressure fatigue testing requirements can vary considerably between applications. The required pressure range, number of test stations, cycle requirements, test medium, and control arrangement should therefore be established before equipment selection.

Highlight also states that it supports both standard models and project-based personnalisation, including test bench configuration and fixture matching.

Liquid Test Fatigue Test Bench vs. Ordinary Pressure Test Equipment

Not every pressure test system serves the same purpose.

A pressure test may focus on reaching a specified pressure and observing whether a component can withstand or maintain it. A fatigue or pulse test adds another dimension: repetition.

Le Essai en milieu liquide Banc d'essai de fatigue is specifically configured to pressurize, unload, and repeat the process automatically. This allows pressure cycling to continue according to the configured pulse count and frequency.

For buyers searching terms such as pressure testing equipment, hydraulic pressure test equipment, pressure fatigue testing equipment, or pressure pulse test system, this distinction is important.

The correct equipment depends not only on the maximum pressure. Buyers should also define whether they need static pressure testing or repeated pressure cycling.

What Information Should You Provide When Selecting a Hydraulic Fatigue Test Bench?

The product specification itself shows why maximum pressure alone is not enough to select the right equipment.

Before configuring a Liquid Test Fatigue Test Bench, the important project parameters include the required test pressure, test medium, required pulse frequency, cycle count, and number of test pieces.

For this product family, Highlight publishes several pressure ranges rather than claiming one configuration fits every application. The number of simultaneously tested pieces is also designed according to customer requirements.

Therefore, when requesting a quotation, providing the actual test conditions allows the engineering team to determine the appropriate pressure testing system instead of selecting equipment solely by a headline maximum-pressure figure.

From Hydraulic Oil Preparation to Equipment Installation

Hydraulic oil was purchased and prepared, followed by installation of the equipment. These steps correspond directly with the product’s confirmed operating characteristics: the equipment supports hydraulic oil or water as the test medium and uses a hydraulic drive system for repeated pressure cycling.

For Highlight / ODMT, projects like this are part of supplying industrial pressure testing equipment around the actual test requirement rather than simply delivering a generic pressure machine.

The company’s published product capabilities cover adjustable pressure, automated pressure cycling, computer control, configurable pulse frequency, configurable cycle count, and customer-specific test-piece arrangements.

The next technical steps for any project should always depend on the customer’s actual configuration and test requirements.
