A detailed description of the pressure gauge Pulse Test Fatigue Test: I designed the gauge hose pulse test bed made, is to learn advanced foreign experience, combined with a high-performance test station corresponding actual needs of the domestic industry developed, the Equipment main components imported hydraulic components, with the United States NI's (LABVIEW software) and control software, making the entire device is simple to operate, stable performance, it can be all kinds of pressure pulse test. This is a suitable hydraulic hose and other hydraulic components for pulse testing experimental device that may offer seven kinds of pressure alternating waveform, and can set their own waveforms: All waveforms can be programmed control, test pressure, peak, slope, etc. can be controlled, and meet the relevant national standards, regulatory requirements, but also meet the specific requirements of a particular experiment; specimens can simulate the environment, such as pressure, temperature, humidity, flow, corrosion; precise control pressure stable, high efficiency, and with innovative designs and reliable original highly integrated mechatronic systems that meet the rigorous testing needs of pilot users. High stability of the IPC, with a printer, keyboard, and use Labview industrial software, security and stability can record the experimental data with waveform. Scope: Automobile steering control, brake pipes, air conditioning pipes, fuel pipes, cooling pipes, cooling hoses, heater hoses, air filter hose, worm, hose pressurization system, engineering hydraulic hose, air hose and manifold, tube or connector, heat exchangers, air conditioners, filters.

Pulse pressure, ambient temperature, medium temperature, number of trials, the waveform can be set through the human machine interface, and print output. ◎ The accumulator fill pressure, improve reliability, stability and longevity pressurized systems, while ensuring the accuracy of the pressure. ◎ automatically excluded beginning of the test gas within the sample (for hose testing), to test the pulse frequency, automatically shut down, and the media has leaked after the demolition of the workpiece automatic recovery feature. ◎ observation window for the protective net lining, the outer layer of plexiglass, maximize the protection of personal safety. Built-in lighting, easy to poor lighting, the assembly and disassembly of the workpiece and observing internal testing situation. ◎ hydraulic oil cooling method using the fuel tank of hydraulic oil from the circulating cooling water cooler, the effective volume of the tank is 10 times the pumping station pump flow, so the heat itself is good; for motor pumps to work for a long time, on the outside of the tank housing equipped with water-cooled radiator, cooling of the fuel tank. ◎ from the control cabinet and the test piece box of two parts. Equipment rational layout, water separation, all pipes made of stainless steel pipe. ◎ different fixture for hose and hose assemblies are connected; ◎ available with flex impulse test and impulse test without flexing. * (Optional)
