Troubleshooting of high speed bending machine

Release time：2021-10-12　　　　 Browse times

High speed bending machine is a complex with close connection and integration of mechanical equipment, electrical equipment and hydraulic pressure. Hydraulic transmission system, gear transmission and electrical transmission are included in three traditional ways. The design scheme of hydraulic system occupies a key influence on the design scheme of contemporary mechanical equipment. Therefore, when the hydraulic system of the bending machine fails, the harm to all machinery and equipment can be said to be fatal.

Sometimes the failure of the hydraulic system of the high-speed bending machine is caused by the failure of a certain element in the system. Therefore, the first one must find out the faulty element, carry out inspection step by step, find the cause of the failure in the hydraulic system of the bending machine, and carry out maintenance according to the phenomenon.

1. The machinery and equipment of hydraulic transmission system operate abnormally, such as no fitness exercise, unstable fitness exercise, wrong direction of fitness exercise, inconsistent fitness exercise rate, disordered posture order, unstable output force, serious leakage, crawling, etc. No matter what the common causes are, they can be regarded as three problems: flow, pressure and direction.

2. Check the hydraulic circuit diagram, check each hydraulic element, determine its characteristics and efficacy, and basically identify its exposure.

3. List the components related to the fault and analyze them one by one. When carrying out this step, one is to make full use of monthly judgment, and the other is to pay attention to the components that can not be ignored.

4. The components often listed in the list are sorted according to past work experience and difficulty coefficient of component inspection. If necessary, dream out the most important inspection components and the most important inspection positions of components, and allocate testing instruments, etc.

5. Carry out initial inspection on the most important inspection components listed in the list. The following phenomena shall be distinguished in the initial inspection: whether the application assembly line of components is suitable; Whether the accurate measuring equipment, instruments and test standards of components are suitable; Whether the external data signal of the component is suitable; Whether the external data signal has no response, etc. Pay attention to the fault precursors of some components, such as high temperature and noise, vibration and leakage.

6. If no fault is found in the initial inspection, it must be checked continuously with instruments and equipment.

7. Identify the faulty components and repair or replace the unqualified components.

8. Before restarting the server, be sure to carefully consider the cause and adverse effects of the failure. If the fault occurs due to environmental pollution or excessive oil temperature, it should be considered that other components also have the probability of failure. In addition, effective countermeasures should be taken for potential safety hazards. For example, if the hydraulic oil pump fails due to environmental pollution, the system must be fully and carefully deployed before replacing the pump.

After clearing the faults of the hydraulic system of the high-speed bending machine, do not rush for success and start blindly. Be sure to follow certain regulations and procedures. Otherwise, the old faults will be cleared and new faults will appear one after another. At this time, the new phenomena must be cleared again.
