　　What are the methods for troubleshooting faults in the blow molding electromechanical gas system?

　　VSP152072 Norgren Blow Molding Valve Group Maintenance Kit inspection method. The blow molding machine operates according to a certain procedure, and each operation must go through the cycle process of mold closing, seating, injection, cooling, glue melting, ejection, seating, mold opening, ejection, and entering the next cycle. Each step is called a working link, and each working link has an independent control circuit. The program inspection method is to confirm which control links have specific faults, making the direction of fault elimination clear. Targeted fault elimination is very important. This method is applicable not only to contact electrical control systems but also to non-contact control systems such as PC control systems or microcontroller control systems.

　　Static resistance measurement method. The static resistance measurement method measures whether the circuit's resistance is normal with a multimeter when powered off, because any electronic component has a P and N structure, and its resistance values are different for positive and negative. Any electronic component also has a certain resistance; if the resistance value connected to the circuit is not equal to zero, it is infinite. Therefore, measuring its resistance value can determine whether it meets the requirements. This method can also check for faults in electronic circuits and is safer. The potential method. If the fault location is uncertain, the static resistance measurement method can be used to measure the power potential of all electrical or electronic components under the current situation, because under normal circumstances, in rare cases, the potential at every point in the current closed-loop circuit is determined. The so-called potential at every point refers to the different potential of each component in the circuit relative to ground, and the network has certain size requirements. Current flows from high potential to low potential, and the potential size of electronic components should conform to this rule when measured along the current direction. Therefore, measuring whether the potential at relevant points on the control circuit meets the specified values with a multimeter can determine the fault point, and then determine why the current value has changed, whether it is due to incorrect power supply, circuit disconnection, or component damage.

　　VSP152072 Norgren Blow Molding Valve Group Maintenance KitThe control link circuit is a combination of switches or relays with contactor contacts. When one or more contacts are suspected of being faulty, the contacts can be short-circuited with wires. If the fault disappears after powering on, it proves the judgment is correct, and the electrical component is damaged. However, please remember that when a fault is found, the short circuit should be removed immediately after testing. Replacing switches or short-circuiting switch contacts is not allowed. The short-circuit method is mainly used to find breakpoints in electrical logic relationship circuits. Of course, this method can also be used to measure electronic circuit faults sometimes. Circuit breakers. The control circuit may also have some special faults. This indicates that some contacts in the circuit are shorted. A good method to find such faults is to disconnect the suspected faulty contacts. If the fault disappears, it indicates that the judgment is correct. The circuit breaker method is mainly used for the logical relationship between fault points.

　　VSP152072 Norgren Blow Molding Valve Group Maintenance Kit: According to the above methods, if a fault is found to be caused by a certain point or circuit board, the suspected faulty component or circuit board can be removed and replaced with a new or confirmed non-faulty component or circuit board. If the fault disappears, the judgment is correct. Conversely, continuous searching is necessary, and maintenance personnel often have spare parts for fragile components or important circuit boards. Once a fault occurs, replacing a part can solve the factory issue. Bringing back the faulty components and slowly finding and repairing them is also one of the methods for quickly eliminating faults.

　　VSP152072 Norgren Blow Molding Valve Group Maintenance KitIn order to quickly eliminate faults, in addition to continuously summarizing one's practical experience, one must also continuously learn from others' practical experiences. Practical experience often allows the faults of blow molding machines to have certain patterns to follow. Some experiences are important lessons cultivated with sweat, and everyone should pay more attention. Usually, this kind of experience enables us to quickly eliminate faults, reducing accidents and losses. Of course, strictly speaking, blow molding machine accidents should be eliminated, which is the responsibility of maintenance personnel.
