This test system adopts the multi-channel electro-hydraulic servo controller (r) with microcomputer-controlled electro-hydraulic servo fatigue test control technology as the core, which is patented technology (patent number:) protected by the State Intellectual Property Office of Lichuang Company. The system is stable. , excellent performance, synchronized with the world, easy to operate.
The test software works in a Chinese environment, has powerful data processing functions, automatically saves test conditions and test results, displays and prints random group test data, test curves, and test reports that comply with relevant national standards. It is widely applicable to It is an ideal and cost-effective test equipment for scientific research institutes, metallurgical construction, national defense and civil air defense, colleges and universities, machinery manufacturing, transportation and other industries.
2. System component functions and configuration:
The actuator has a built-in high-precision displacement sensor, the force sensor uses an imported dynamic sensor, the actuator uses high-speed imported sealing components and high-quality electro-hydraulic servo valves .
The controller is equipped with a power supply to prevent the testing machine from running out of control when the power supply is suddenly interrupted.
The oil tank consists of a box body, an oil filter at the suction port, a filter screen between the oil suction area and the oil return area, a liquid level indicator, an electrical contact temperature gauge, an air oil filter, an outlet stop valve, an oil drain valve, and a fuel tank. Cover plate composition. The inside and outside of the fuel tank are spray-coated to prevent corrosion of the fuel tank. System pressure, oil temperature and oil level can be controlled.
The oil source of the test system is composed of multiple oil sources connected in parallel. The oil tank is made of stainless steel and is equipped with a starting motor and pump unit respectively, which can be controlled independently to achieve the effect of saving energy and satisfy the different working conditions of various components at the same time. work requirements. The motor is equipped with a manual variable pump, and a pump unit is formed through an elastic coupling.
The hydraulic valve group consists of a one-way valve, a high-pressure oil filter, a pressure difference signaling device, a low-pressure return oil filter, a high-pressure accumulator, an anti-shock pressure gauge, a pressure gauge switch, and an electromagnetic overflow regulator that regulates system pressure. It is composed of flow valve, valve plate connecting oil pipe and joints. The oil pump pumps out high-pressure oil and outputs it to the actuator through the one-way valve and high-pressure oil filter. The pressure adjustment is completed by the electromagnetic relief valve. The high-pressure accumulator is used to adjust the pulsating pressure of the oil source to ensure stable output flow pressure. The safety valve prevents oil The starting pressure in the source exceeds the limit.
The cooler system consists of a cooler, oil pipe joints, oil pipes, and valves. The oil inlet and outlet adopts a series structure. The cooler is connected to the hydraulic circuit. The oil heat exchanges with the cooling water through the cooler to reduce the oil temperature.
The drag box used in the oil independent control system consists of a box, AC contactor, air switch, intermediate relay, overpressure-overtemperature-overpressure difference alarm circuit, and phase loss protection circuit.
