PVT Testing Machine

This is a comprehensive testing machine specifically designed for testing specimens that use automotive coolant and have small pulse pressures, high pulse frequencies, and large expansibility, using a dynamic composite loading of internal pressure (P), external vibration (V), and (internal and external) temperature (T) to test the reliability of the specimens. It can also perform tests for flow rate (medium) and humidity (environment).

It is a servo-hydraulic closed-loop control system that is specially developed for testing specimens such as liquid-cooled plates, cooling hoses and joints, radiators, and heating cores of automotive cooling systems. The pressure waveform and test temperature are adjustable and controllable.

Applicable objects: liquid-cooled plates, cooling hoses and joints, radiators, heating cores, etc. in automotive cooling systems.

Applicable standards: GMW 14785, GMW 14329, GMW 18152, TL 52361, SAE J1610, GB 18948, QC/T 468, etc.

Functions and Features

1. The machine uses intelligent hydraulic servo control technology, with controllable pulse pressure waveform (trapezoidal wave, triangular wave, quasi-sinusoidal wave, etc.), pulse frequency, and medium temperature.

2. The test is controlled by a computer, which can real-time sample pressure, flow rate, temperature, vibration, waveform, pulse frequency, and other contents.

3. The overall design is modular, which is easy to install, adjust, and maintain.
