From type to application: Overview of the key points and development trends of pressure testing machines

Introduction to the basic types and functions of pressure testing machines

Pressure testing machine is an important testing equipment widely used in various industries. Its main function is to test the performance and behavior of materials, products or components under pressure by applying external pressure. With the advancement of science and technology, the types and functions of pressure testing machines are becoming more and more diverse, which can meet the testing needs of different fields.

Types of pressure testing machines

According to the working principle, structural design and application scope, pressure testing machines can be divided into several different types, suitable for different testing needs.

Single-arm pressure testing machine is one of the most basic types, usually consisting of a main bracket and a movable pressure arm. It is suitable for testing a single material or a small range of loads. It has a simple structure and convenient operation. It is often used for preliminary tests under low load conditions. Single-arm testing machines are generally used for some conventional strength tests and material tests, such as testing the compressive strength of materials such as metals and plastics.

Compared with the single-arm testing machine, the double-arm pressure testing machine adds a second pressure arm. This design makes the pressure applied to the test material more uniform, so it can better test some parts with complex shapes or materials under greater pressure. Double-arm testing machines are often used to test components with higher loads, especially in fields with high precision requirements, such as aviation, automobiles, etc.

The CNC pressure testing machine is equipped with a computer control system, which can accurately set parameters according to the test requirements and automatically complete the test process. This type of equipment has a high degree of automation and is suitable for mass production and high-precision testing. Through the CNC system, users can accurately control the pressure changes during the test, monitor the test data in real time, and perform data analysis and report generation.

The microcomputer-controlled pressure testing machine is a more intelligent device. In addition to the CNC function, it also has stronger data analysis and processing capabilities. The microcomputer-controlled testing machine can realize a variety of test modes, such as constant pressure, variable speed loading, etc., which are suitable for some fields that require higher test accuracy. In addition, this type of equipment can also display test data in real time to help engineers make more accurate judgments.

Water pressure testing machines and air pressure testing machines are mainly used to test the performance of equipment such as pipelines and containers in liquid or gas environments. The water pressure testing machine applies water pressure to the inside of the test object to detect its sealing, strength and other properties, and is usually used for safety testing of pressure vessels and pipelines. The air pressure testing machine uses gas as the test medium and is suitable for testing gas pipelines, gas sealing equipment, etc.

Functions of pressure testing machine

The main function of pressure testing machine is to measure and evaluate the behavior of the object under different pressure environments by applying external pressure. The following are several main functions of pressure testing machine.

Measuring compressive strength is one of the most basic functions of pressure testing machine. During the test, the tester gradually increases the pressure applied to the sample until the material is damaged or reaches the maximum pressure it can withstand, thereby determining the compressive limit of the material. This is crucial for developing new materials and evaluating the performance of existing materials, especially in industries such as construction and automobiles, where the compressive strength of materials directly affects the safety and reliability of products.

Evaluating deformation capacity is another key function. During the process of applying pressure, the pressure testing machine can record the deformation of the material and evaluate its elastic and plastic properties under different pressures. When a material is subjected to pressure, it may undergo different forms of deformation, such as elastic deformation, plastic deformation or fracture. By testing these deformations, the mechanical properties of the material can be obtained to help engineers improve the design.

Detecting tightness and leakage. For equipment with high sealing requirements such as pressure vessels and pipelines, pressure testing machines can detect whether there will be gas or liquid leakage under a specific pressure. During the test, after applying a certain amount of pressure, the tester will monitor whether there is any leakage to ensure that the tested object will not cause danger during actual use.

Evaluate fatigue and life. By repeatedly applying pressure, the pressure tester can simulate the fatigue process of materials and equipment during long-term use. This is of great significance for some long-term products, such as automotive parts, aircraft equipment, etc. By measuring the performance of materials under multiple pressures, engineers can estimate the service life of the product and discover potential safety hazards in advance.

Data recording and analysis. Modern pressure testers are equipped with powerful data recording and analysis functions. Important data such as pressure value, deformation, and failure point during the test can be recorded in real time and analyzed by software. Data analysis can help engineers further understand the performance of materials and components, optimize designs, and improve product quality. Many advanced testing machines can also generate test reports to facilitate subsequent quality assessment and improvement.

Application areas of pressure testers

Pressure testers have been widely used in many industries, mainly in the following areas:

Construction industry: The compressive strength of building materials such as concrete and steel is a key factor in determining the safety of buildings. During the construction process, pressure testing machines are used to test the strength and stability of materials to ensure that the building can withstand the pressure applied by the outside world.

Automotive industry: Auto parts, especially brake systems, fuel pipes, fuel tanks, etc., are often subjected to high pressure during operation. Pressure testing machines can test the strength and pressure resistance of these parts to ensure that they can maintain normal operation in complex working environments and ensure driving safety.

Aerospace: Aircraft, rockets and other aerospace components need to withstand extreme air pressure changes and external pressure. The application of pressure testing machines in the aerospace industry is mainly to test the performance of components under high pressure, low pressure or other special environments to ensure the safety and reliability of aircraft.

Oil and gas: Pipelines and pressure vessels in the oil and gas industry are often subjected to huge pressure. Pressure testing machines are used to test the sealing, strength and pressure resistance of these equipment to ensure that no leakage or rupture accidents occur during long-term use.

Electronic and electrical: Some electronic components, such as batteries, capacitors, etc., may be subjected to certain pressure during operation. By using pressure testing machines, the performance of these components under different pressure conditions can be tested to ensure their reliability and safety.

Safety regulations and maintenance recommendations for using pressure testing machines

Safety regulations and maintenance recommendations for using pressure testing machines

As precision experimental equipment, pressure testing machines are widely used in the fields of material testing, performance evaluation, product quality control, etc. Because its working process involves high-pressure loading and mechanical moving parts, improper use may cause safety hazards such as equipment damage and operator injury. Scientific use and standardized maintenance of pressure testing machines are important prerequisites for ensuring a smooth and safe testing process and extending the service life of the equipment.

Understand the equipment operating instructions

Before using the pressure testing machine, the operator should be fully familiar with the equipment's operating instructions and understand the operating methods and workflows of various functions. Including the equipment's startup sequence, loading method, limit setting, test parameter setting method, and emergency shutdown steps. The operating instructions will also clearly state when the equipment should not be operated and how to handle abnormal conditions.

Many devices are equipped with electronic control systems and digital display interfaces. Users need to master the basic parameter setting logic and menu navigation methods to ensure that there will be no deviation in test results or equipment failures due to operating errors.

Ensure a compliant operating environment

The pressure testing machine should be placed in an environment that meets the equipment's use requirements. Generally, the installation site is required to have a flat and solid floor, good ventilation conditions, and proper lighting. Avoid using in humid, dusty, high temperature or frequently vibrating environments to prevent affecting the performance of the equipment's electronic system and mechanical components.

The power supply voltage should be within the range marked on the equipment nameplate, and the grounding wire connection must be reliable to prevent damage caused by leakage or short circuit. For some test machines that require compressed air or hydraulic system drive, the cleanliness and stability of the air source or hydraulic system should also be ensured.

Operator qualifications and training

Personnel using pressure testing machines should have the corresponding basic knowledge of mechanical or material experiments, and can only operate after equipment operation training. Unauthorized or unfamiliar personnel are not allowed to operate without authorization.

The training content should include basic structure introduction, safety precautions, parameter setting methods, common fault identification, emergency handling procedures, etc. Through unified training, equipment damage or safety accidents caused by improper human operation can be effectively reduced.

Safety inspection before testing

Before officially starting the test, the equipment should be fully inspected to ensure that all parts are in normal condition. Including:

Check whether the power cord and signal line are intact;

Confirm whether the pressure sensor and limit device are firmly installed;

Check whether there are foreign objects or looseness in the loading part;

Verify whether the pressure value of the hydraulic or pneumatic system is within the safe range;

Check whether the specimen is correctly installed according to the specifications to avoid problems such as eccentricity or lack of clamping.

These checks help prevent test anomalies or equipment damage caused by improper preparation.

Set reasonable test parameters

During the pressure test, parameters such as loading speed, target pressure, and holding time must be set according to the actual performance of the object being tested and the test standard, and avoid using parameters that exceed the rated range of the equipment.

Unreasonable loading rate or target value may cause the test machine to be overloaded, causing damage to the mechanical structure or the activation of the safety protection system. At the same time, too fast loading may cause the test sample to rupture suddenly, affecting the authenticity of the data and bringing safety risks.

If the test task involves material damage, the monitoring operation should be carried out at a safe distance, or a protective cover should be used to shield possible flying debris.

Safety precautions during operation

For pressure testing machines equipped with hydraulic or pneumatic systems, maintenance of related systems is particularly important. Long-term use of hydraulic oil will cause contamination and viscosity changes, affecting the stability of pressure output, and should be replaced according to the manufacturer's recommended cycle.

The hydraulic system also needs to regularly check whether there is leakage in the seal ring, oil pipe, and valve to avoid unstable pressure or oil contamination affecting the test accuracy.

For pneumatic systems, attention should be paid to the cleanliness and dryness of the air source. The configuration of air source purification devices (such as dehydrators and filters) can effectively extend the service life of system components.

Regular update and calibration of software systems

Modern pressure testing machines are mostly equipped with microcomputer control systems or embedded control platforms, and the operating software should be updated regularly to ensure system compatibility and functional integrity. Some equipment manufacturers will release software upgrade patches or function optimization packages from time to time, and users should actively obtain update information.

The force value, displacement and other sensor systems of the equipment should be calibrated regularly to ensure measurement accuracy. Calibration can be entrusted to a qualified testing agency, or professional services can be provided by the equipment supplier. It is recommended to perform a complete calibration at least once a year, especially after a large load test or after repairing and replacing parts.

Emergency Fault Handling Procedure

If a sudden fault occurs during the operation of the equipment, it should be handled in accordance with the emergency handling procedure established in advance. Common faults include:

Power interruption: turn off the main switch, check the power circuit and restart;

No response to the pressure value: check whether the sensor connection and control cable are loose;

Abnormal display: restart the control software or hardware system;

Abnormal sound: stop the machine immediately to check whether the mechanical parts are loose or stuck.

In order to reduce the impact of emergencies, common maintenance tools and spare parts should be equipped in the laboratory, and operators should be trained to have basic troubleshooting capabilities.

Parts replacement and technical support

Some parts of the pressure tester, such as oil seals, pressure gauges, sensors, solenoid valves, etc., are consumable parts and should be replaced in a planned manner according to the frequency of use and service life to avoid affecting the performance of the whole machine due to the aging of small parts.

When the equipment failure exceeds its own processing capacity, the original manufacturer or authorized service provider should be contacted in time. It is not recommended to disassemble complex parts by yourself. Equipment manufacturers usually provide various forms of technical services such as telephone support, remote diagnosis, and on-site maintenance. They should ensure that the procurement channels are regular to facilitate the acquisition of subsequent services.

Requirements for shutdown storage and long-term sealing

When the equipment is not used for a long time, it should be properly shut down and preserved. Including:

Cut off the power supply of the equipment and unload the pressure to zero;

Clean the surface of the equipment and all moving parts to avoid dust accumulation;

Apply anti-rust grease to the exposed metal parts;

Store in a low-humidity environment and use moisture-proof packaging when necessary;

If the storage time exceeds half a year, a comprehensive inspection and trial operation should be carried out before re-use to ensure that there are no abnormalities in the system.
