Injection Molding Machine Screw and Barrel manufacturers take you to understand the necessary ideas for injection molding machine maintenance
Injection Molding Machine Screw and Barrel manufacturers tell you that the core of plastic machine maintenance work is fault judgment and fault handling. It involves a wide range of knowledge, a large degree of complexity, and has a certain depth (such as comprehensive professional knowledge level). It is necessary to have basic knowledge of mechanical equipment maintenance, basic knowledge of hydraulic maintenance, and basic knowledge of electrical maintenance.
The manufacturer of Injection Molding Machine Screw and Barrel tells you that the maintenance work of injection molding machine is hard, but it is also a process of continuous learning and progress. As long as you master the basic working principles of injection molding machines and master the basic working methods, no matter the various models, you will always be inseparable from it. Zong, can explore a set of maintenance procedures to ensure the normal operation of the injection molding machine.
Maintenance workers must first understand and master the contents of the operation manual of the injection molding machine, be familiar with and master the mechanical parts, circuits and oil circuits of the injection molding machine, understand the working process of the machinery, circuits and oil circuits when the injection molding machine is working normally, understand and Master the inspection and maintenance methods of electrical components and hydraulic components. Clear the normal working state and abnormal working state to avoid time-consuming misjudgment and misassembly.
Maintenance work must understand the operation method of the equipment and have some basic knowledge of injection molding, and use the injection molding machine correctly. Injection Molding Machine Screw and Barrel manufacturers tell you that if you do not know how to operate the injection molding machine, the maintenance work is very difficult, and the fault diagnosis may be unreliable. The circuit boards and electrical components in the injection molding machine are affected by high temperature, environment, time and other factors for a long time, the device operating point is shifted, and the aging degree of the components is within the normal range.
Therefore, debugging the injection molding machine is also one of the essential basic skills in maintenance work. It is very important to understand the working procedures of the injection molding machine, and to debug the electronic circuit and hydraulic oil circuit of the injection molding machine.
In order to achieve accurate, reliable and timely maintenance work, it is necessary to study and master the contents of the instruction manuals of various types of injection molding machines. In the general maintenance process, the maintenance ideas are usually circuit-oil circuit-mechanical parts action. The adjustment work is carried out in reverse. If the mechanical action and clamping pressure are lacking, the oil circuit and circuit can be found. If the circuit output is normal, the oil circuit valve can be adjusted.
The manufacturer of Injection Molding Machine Screw and Barrel tells you to adjust the circuit board if the oil circuit is working properly. Of course, the final adjustment is made, but the relationship between the three is interdependent and controlled. Correct use of instruments, adjustment of detection circuits, maintenance of oil circuits, and adjustment of the position and movement of mechanical parts are important means of judging faults.
Generally, the injection molding machine manufacturer only gives the electrical block diagram of the equipment, the block diagram of the oil circuit and the main parts of the machine, which is not enough for maintenance work. It is necessary to pay attention to the collection and arrangement of relevant data in all aspects during the daily maintenance work. Such as electrical, electronic, mechanical spare parts, oil circuit, solenoid valve body, etc.
Measure the specific parameters of its detection point. When necessary, it is necessary to make the power supply, simulate the input and output signals, and carry out simulation tests or adjustments to master and obtain the first-hand maintenance data, such as the parameters of the working points at all levels.
The same is true for oil circuit maintenance, which must be comprehensively adjusted and maintained according to the characteristics of the oil circuit and hydraulic solenoid valve. There is an opportunity to disassemble, clean, inspect and install the solenoid valve frequently. These processes cause a lot of trouble, but are crucial.
The manufacturer of Injection Molding Machine Screw and Barrel tells you that the maintenance work must master and sort out the fault maintenance method and judgment procedure diagram in line with the principle and logic system. In combination with the actual maintenance work on weekdays, collect relevant information on the injection molding machine, such as troubleshooting, the method There are various methods such as the step-by-step inspection method, the simulation inspection method, the voltage test method, the on-off test method, and the circuit board replacement method.
The manufacturer of Injection Molding Machine Screw and Barrel tells you to re-adjust the working point, re-adjust, and carry out a load test after repairing to make the equipment work within the parameters listed in the operating instructions.
