70MPa PTM707A impulse test stand - oil

PTM707A series high pressure impulse testing machine is used for engineering hydraulic hose, aviation hose, steel wire reinforced rubber hose, high pressure tubing and hose assemblies and other pulse testing requirements. The equipment simulates the actual working condition of the pipeline and its joint in the operating system, tests the pipeline joint according to relevant technical standards and requirements, and verifies the durability of the pipeline joint. It is widely used in aerospace enterprises, construction machinery industry, coal industry, product quality inspection institute, third-party testing center, scientific research institutions and other fields.



1. servo control system automatic control; Before the start of the test, the large cycle automatically emptying; Pulse pressure, test times and pulse waveform can be set by computer.

2. with automatic stop protection function after the specimen is damaged, suitable for unguarded; The fixture is suitable for quick connection of hose assembly; The main components are imported parts, safe and reliable;

3. The internal structure is reasonable, the layout is beautiful, the use of non-welding pipeline connection, prevent running and leaking, and convenient maintenance; The system is compact in structure, easy to upgrade, easy to install, adjust and maintain

4. Overtemperature, overpressure, leakage alarm stop, open the door automatic stop, automatic stop in case of failure and other safety protection functions;

5, interface dynamic display test data, and draw real-time time-pressure waveform, waveform curves smooth; NI data acquisition software is used for real-time analysis and storage, and the experimental report can be generated for printing.
