Do we need to master the manual to repair the PE blow molding machine?

The problem of the oil circuit in PE blow molding can have some impact on the work. To maintain the work accurately, reliably, and timely, it is necessary to study the content of various blow molding machine manuals and master the general maintenance process. The maintenance idea is usually the action of the circuit oil mechanical components.

In the opposite direction of adjustment, if the mechanical action and mold clamping pressure are missing, the circuit and circuit can be found. If the circuit output is normal, then adjust the oil valve. If the circuit is working properly, adjust the circuit board. Of course, the final tone, but the interdependence and mutual control among the three. The correct use of instruments and meters, adjustment of detection circuits, maintenance of circuits, and adjustment of the position and action of mechanical parts are important means to determine faults. Generally, blow molding machine manufacturers only provide the electrical diagram, oil circuit diagram, and main mechanical parts of the equipment, which is not sufficient for maintenance work.

Attention must be paid to daily maintenance work, collecting and organizing relevant information in all aspects. Information such as electrical, electronic, mechanical accessories, oil, electromagnetic valve bodies, etc. For example, if necessary mapping circuit schematics, electronic mapping schematics, and actual wiring diagrams are required in the electrical aspect, corresponding terminal equipment detection related information can be provided to provide accurate detection direction during maintenance fault diagnosis and analysis. Measure the specific parameters of the detection point.

When necessary, it is also possible to generate its own power supply, simulate input and output signals, conduct simulation testing or calibration to grasp and obtain first-hand maintenance data, such as the working points of various parameters.

The PE blow molding machine and fully automatic bottle blowing machine are based on precise calculation of the mold head flow channel design, streamlined, no dead corners, and can quickly change colors

Ensure low back pressure and effectively extend the service life of the extrusion system and gearbox.

The multi chamber mold head of the fully automatic bottle blowing machine has a reasonable distribution of flow channels, and the flow rate can be easily adjusted.
