Maintenance of plastic steel door and window equipment

Plastic steel doors and windows equipment often encounter anomalies in use, but there are not many real faults. However, once the equipment failure of plastic steel doors and windows equipment will affect the normal production of plastic windows, the economic benefits of the enterprise will be lost. The failure of the plastic steel door and window equipment should be solved in time. The following introduces the maintenance of the plastic steel door and window equipment according to the years of maintenance experience of our company's after-sales service department:

(1) Pay attention to investigation and understand the situation when the fault occurs, so as to find relevant factors from it.

(2) Observe the fault site and see if there are other abnormalities in the equipment status, so as to facilitate a comprehensive and comprehensive analysis.

(3) Understand the principle of plastic steel doors and windows equipment, that is, the principle of the whole machine of plastic steel doors and windows equipment and the structural principles of the mechanical structure, electrical and pneumatic components of the equipment, so as to establish a correct maintenance idea.

(4) Master the common operation and maintenance knowledge of plastic steel door and window equipment.

(5) Note that there are many possible causes of the same fault, and it should be considered comprehensively.

(6) The specific problem should be analyzed in detail. The same fault phenomenon may be caused by different reasons.For example, the device does not move after the button is pressed by the double-angle saw, which may be caused by poor contact of the button contacts or the solenoid valve core stuck. .

(7) Comprehensively consider from the aspects of mechanical, electrical, and pneumatic, combined with the specific phenomenon of the failure, analyze the range of possible related factors of the failure, and gradually define, gradually narrow the scope of failure consideration.

(8) Analyze the particularity of the mechanical, electrical and pneumatic principles of plastic steel doors and windows equipment, as well as the specific structure and principles of specific equipment, such as welding machine equipment (including linear layout welding machine, ordinary four-corner welding machine) corner seam cleaning machine and other equipment All are controlled by the programmable controller (PC). Therefore, when these devices fail, you can first analyze whether the PLC is in the control system of the whole machine, such as welding machine, There is a heating control system independent of the programmable controller. Then, according to the status of the programmable controller indicator, the corresponding input and output terminals, etc., determine whether it is a programmable controller. Failure, and then check the pneumatic components (mainly solenoid valves) controlled by them and the mechanical devices driven by the pneumatic components.

(9) Check the function of equipment mechanical structure through power failure and gas failure.

(10) Power-on inspection, the analysis idea can be developed around the fault point. If the device does not move after the button is pressed, the voltage of the button input, the voltage at both ends of the button, the solenoid valve controlled by the button lock, and other electrical components can be measured in turn. Check the function of electrical components such as solenoid valves.When using power-on inspection, you must pay attention to safety.

(11) After troubleshooting the plastic steel door and window equipment, you should pay attention to summarizing the correct use of the equipment to avoid the same or similar failures again.
