Maintenance skills of hydraulic universal testing machine

Microcomputer hydraulic servoHydraulic universal testing machineIt is an advanced material testing machine. It uses it to test the mechanical properties of metal data in tensile experiments. The performance indicators that can be tested include: upper yield strength, yield strength, triple strength, tensile strength, regular non-proportional extension strength, elastic modulus, and elongation after break. The regular non-proportional extension strength and elastic modulus need to be measured by the device electronic extensometer. Ordinary enterprises purchase electronic hydraulic universal testing machines for tensile, compaction, bending, friction, peeling/tearing and other experiments.
Regularly check the screws in the jaw area and tighten them in time if they are loose. As an equipment necessary to control the quality of production, the hydraulic universal testing machine should be used to remove problems and ensure the good operation of the machine. Operators should learn to find problems and be able to clean them. The dial pointer is poorly flexible, there will be a mid-range stop after unloading, or the zero point position will change frequently. The causes of this phenomenon are multifaceted. The pulleys and tracks on the toothed rods are too dusty and rusted. At this time, you need to remove the cleaning and add a little watch oil. The pointer rotation shaft is dirty and should be cleaned. If there is contact between the tooth rod tablet and the tooth rod, it should be loosened. If the oil return condition of the hydraulic universal testing machine buffer is poor, it should be adjusted or cleaned. The belt on the force-testing piston is scattered or too loose (makes the piston unable to operate at a constant speed). When the friction force of the force-testing piston increases or gets stuck in the oil cylinder, use chromium oxide grinding paste to grind until it is normal. There are obstacles during the lifting process of the pendulum, or the pendulum axis is too dirty or rusted, causing the pointer to return to zero and change greatly.
