Automobile brake hose impulse tester

Automobile brake hose impulse tester

Product Introduction:

The tester adopts an advanced hydraulic drive system, combined with high-precision pressure sensors and intelligent control modules, which can accurately generate and control pulse pressure waveforms, frequencies and amplitudes. During the test, the automobile brake hose specimen is properly connected to the test circuit, and the equipment applies cyclic pulse pressure to the hose according to the preset test procedure. At the same time, multiple high-sensitivity sensors monitor key parameters such as pressure changes, deformation, temperature fluctuations, and leakage of the hose in real time. After being processed by a high-speed data acquisition system, the collected data can be intuitively presented on the operation interface, and a detailed test report can be automatically generated, which is convenient for users to conduct a comprehensive evaluation and in-depth analysis of the performance of the brake hose.

Equipment functions and features:

1. It consists of a microcomputer and a programmable PLC controller with two levels of control system. The control principle is advanced and an independent control unit is used to truly realize modular control. It can accurately control the pressure accuracy, has a good pressure-maintaining effect, and automatically replenishes pressure in real time;

2. Multi-channel and multi-station, each test can be carried out simultaneously without affecting each other, and the experimental data and graphics are automatically recorded and saved in the computer;

3. The electrical components use imported components, which ensures the accuracy and stability of the test machine from the control principle and the quality of the electrical components;

4. This machine has an overload protection function and an equipment pressure calibration function;:

5. After the specimen breaks, the pressure drops rapidly and the pressurization stops automatically, ensuring personal safety to the maximum extent

6. Manual control, single-chip microcomputer or PLC control and computer control can be selected according to needs;

7. Various types of fixtures can be designed for customers individually:

8. The computer accurately records the parameters and automatically stops after the specimen is broken, which is suitable for unattended occasions.

FAQ

(1) What are the requirements for the equipment installation site?

The equipment installation site should be flat, dry, well ventilated, and have a stable three-phase four-wire power supply (AC 380V±10%, 50Hz±1Hz). The site area should not be less than 1 meter of operation and maintenance space around the equipment's overall dimensions, and the ground bearing capacity should be able to withstand the weight of the equipment (about 1500kg) and possible additional loads. At the same time, it is recommended that the temperature of the installation site be kept between 10℃ - 35℃ and the relative humidity be no higher than 80% to ensure the normal operation and service life of the equipment.

(2) How to perform daily maintenance of the equipment?

Daily maintenance mainly includes cleaning the appearance of the equipment, regularly checking the hydraulic oil level (it should be kept between the upper and lower scale lines of the oil level gauge), calibrating the pressure sensor and displacement sensor (recommended once a quarter), and checking whether each connection is loose. In addition, attention should be paid to the cleanliness of the test chamber to avoid accumulation of debris that affects the test results or damages equipment components. For detailed daily maintenance steps and precautions, please refer to the maintenance section in the equipment manual.

(3) Can the equipment test multiple brake hoses at the same time?

The standard configuration of this equipment is for testing a single brake hose, but it can be customized and upgraded according to customer needs to achieve the function of testing multiple brake hoses at the same time. When customizing, it is necessary to consider adding corresponding hydraulic circuits, sensors, control modules and other components to ensure that the test parameters of each hose are independent and accurately controllable. If there are multiple hose testing requirements, please communicate with our sales team in detail about the customization plan and related technical details before purchasing the equipment.

(4) What are the storage and export formats of test data?

The equipment can store a large amount of test data. The storage capacity depends on the configuration and can generally meet the storage requirements of thousands of test data. Test data can be exported to common file formats, such as Excel table format (.xlsx), PDF document format (.pdf) and text format (.txt), etc., which is convenient for users to organize, analyze and generate reports. Users can select the data export function in the operation interface and specify the format and storage path of the exported file.
