**How to determine the fault of the oil electric servo pump controlled bending machine**
1、 Introduction
As a precision mechanical equipment, the stable operation of the oil electric servo pump controlled bending machine is of great significance for ensuring production efficiency and quality. However, during use, equipment may malfunction due to various reasons. This article will introduce how to determine the faults of the oil electric servo pump controlled bending machine from the aspects of mechanical component faults, hydraulic system faults, electrical system faults, etc.
2、 Diagnosis of mechanical component failures
1. * * Appearance inspection * *:
Firstly, observe whether there is any obvious wear, cracks, deformation or damage to the mechanical components. Pay special attention to vulnerable parts, such as sliders, bearings, gears, etc.
2. * * Sports flexibility * *:
Check if all moving parts are flexible and free from jamming. For example, the movement of the slider on the guide rail should be smooth and unobstructed.
3. * * Connection fastening * *:
Check if all connectors are tight and there is no looseness. Pay special attention to fasteners such as bolts and nuts to ensure that their locking force is moderate.
4. * * Functional verification * *:
Verify the functionality of mechanical components through manual or automatic operation. For example, check whether the upper and lower molds of the bending machine can open and close normally.
3、 Diagnosis of hydraulic system faults
1. * * Oil level inspection * *:
Observe whether the oil level in the hydraulic oil tank is normal and whether there is any abnormal decrease. Low oil level may cause damage to the hydraulic pump or insufficient system pressure.
2. * * Stress testing * *:
Use a pressure gauge to test the pressure values of various parts of the system and determine if they meet the equipment requirements. Abnormal pressure may indicate issues such as leakage, blockage, or pump damage.
3. * * Leakage inspection * *:
Check for leaks in hydraulic pipelines, fittings, seals, etc. Leakage may cause a decrease in system pressure and an increase in oil temperature.
4. * * Action check * *:
By observing the action of hydraulic cylinders, motors, and other executing components, determine whether the hydraulic system is operating normally. If the hydraulic cylinder moves unevenly or has abnormal speed, it may indicate a malfunction in the system.
4、 Diagnosis of electrical system faults
1. * * Power check * *:
Check if the power supply of the equipment is normal, and if the voltage and current meet the requirements of the equipment. Abnormal power supply may cause the device to fail to start or run unstable.
2. * * Control signal inspection * *:
Use tools such as an oscilloscope and multimeter to check if the control signal is normal. Abnormal signals such as encoder signals and servo driver signals may indicate a problem with the control system.
3. * * Alarm information viewing * *:
Check the alarm information on the device control panel to understand the type and location of the fault. Alarm information is crucial for quickly locating and resolving faults.
4. * * Component Inspection * *:
Check if electrical components such as switches, relays, sensors, etc. are working properly. If any component damage or aging is found, it should be replaced in a timely manner.
5、 Conclusion
To determine the fault of the oil electric servo pump controlled bending machine, it is necessary to comprehensively consider factors such as mechanical components, hydraulic system, and electrical system. By inspecting and analyzing the above aspects, the cause of the malfunction can be quickly identified and corresponding measures can be taken to ensure the normal operation of the equipment and the smooth progress of production. At the same time, enterprises should also strengthen the daily maintenance and upkeep of equipment to prevent the occurrence of malfunctions.
