On-line leak detection testing machine is used to detect the self-leakage of hose under positive pressure and negative pressure, and to detect the micro-pressure leakage of specimen, so as to judge whether the specimen product is qualified or not.
The water pulse testing machine is used to test the components of automobile cooling system. It is a comprehensive testing machine with low pulse pressure, high pulse frequency and large expansion specially developed for automobile coolant samples. Electro-hydraulic servo closed-loop control is adopted, and the pressure waveform and test temperature are adjustable and controllable. Each channel can be independently controlled, the flow rate can be automatically adjusted, and each channel can test the pressure.
The oil pulse testing machine is to improve the shortcoming that the high-pressure oil pulse can not control the temperature of the medium in the past, so that the medium can be completely circulated in the pulse experiment, and the pressure waveform, temperature and flow can be controlled in real time. Each channel is controlled separately, and the pressure and temperature of each channel are detected. The performance of this equipment has been improved qualitatively by adopting the integrated way of servo hydraulic and control.
The invention is suitable for pulse test of automobile fuel pipeline, and adopts the principle of servo hydraulic pulse to solve the problems of inaccurate waveform control, low safety performance, inability to automatically extinguish fire and the like in the prior art. ..
The gas cold and hot impact tester and intercooler thermal impact tester are mainly used for the alternating cycle test of air cold and hot inside the charge air cooler (CAC). Thermal shock test is an intensive test to evaluate the performance of intercooler against temperature alternating cycle, which provides experimental data for the design of intercooler, and also verifies the reliability of nonmetal-to-metal connection at alternating temperature, which plays an important role in ensuring the quality of heat exchanger and improving its reliability.
The high and low temperature cycle testing machine adopts touch screen control technology and fully automatic control hydraulic system. The testing machine is aimed at the pressure test of automobile water pipes and cooling systems, and the temperature, flow and pressure are completely independent and controllable.
The high-pressure blasting testing machine is mainly designed for automobile-related fluid pipelines, and uses the gas-liquid ratio to test the ultimate pressure. Pressure and boosting time can be set according to actual needs.
The positive and negative pressure comprehensive pulse testing machine is suitable for simulating the alternating test of positive and negative pressure when the automobile fuel tank assembly and oil pipe are driving, and can be connected with positive and negative pressure for control and output, and the leak detection function can be selected as positive and negative pressure pulse pressure test.
Servo blasting testing machine is the ultimate pressure testing equipment of hydraulic components, which can realize the functions of equal pressure blasting and rapid blasting.
The internal corrosion tester is mainly used to test the internal corrosion resistance of automobile air conditioning and heat exchange system, and to test the influence of long-term operation of the specimen on internal products under the conditions of high temperature, high pressure and flowing medium.
