HRG-107 pulse test bench

1HRG-107 pulse test benchEquipment Overview
This equipment is a hydraulic servo pulse test bench designed and manufactured specifically for low-pressure components such as rubber hoses, cooling water pipes, air conditioning pipes, radiator pipes, and warm air pipes; It has accurate, stable, reliable, and durable pressure, and provides functions such as medium temperature control, which improves the simulation environment of the experiment.
Adopting a highly stable industrial computer, equipped with a printer and keyboard, and using Labview industrial software, it can safely and stably record experimental data and waveforms; This device is the product of your servo pressure pulse test.
IIHRG-107 pulse test benchProvide various conventional pulse waveforms, such as water hammer waves, T-waves, sine waves, triangular waves, sawtooth waves, and square waves. Test personnel can also set and control the output waveforms themselves; The pulse test provides a pressure of up to 80MPa, with a control accuracy of ± 0.1bar, and a test frequency of up to 5Hz (sine wave); Save all test data, the output of the data can print out the number of cycles and cycle pressure waveform, and the memory has USBØInterface, which can output data as an EXCEL document; The pressure rise/release rate can be controlled, with a rate range of 0-800MPa/s.
Medium temperature control: the test medium temperature can be automatically controlled, using the Taiwan, China Taisi temperature control system, equipped with independent power units, control instruments, heating power PID self control, temperature range -60 ℃ -150 ℃, control accuracyر1℃； The control method of the test medium adopts a sealed closed-loop control, which ensures uniform heating of all parts of the specimen and avoids residual air in the specimen, which may affect the normal progress of the pulse test and cause unnecessary damage to the specimen.
Ambient temperature control: the ambient temperature of the test chamber can also be automatically controlled. The temperature can be controlled through the input of the upper industrial computer. The Taiwan, China Taisi temperature control system is used, with independent power units and control instruments. The heating power is self controlled by PID. The test environmental chamber uses dual air duct circulation control to make the temperature of all parts of the test chamber uniform; Temperature range -70 ℃ -200 ℃, control accuracy ± 1 ℃.Ø
Flow closed-loop control: The flow rate of the medium inside the test piece can be automatically controlled, and the flow rate can be controlled through input from the upper industrial computer, with PID automatic control; Equipped with corresponding variable frequency cycle motors, flow meters, etc., closed-loop control of flow is achieved through feedback signals from the flow meters; Flow range 0-100L/min, control accuracy ± 0.2L/min.
