The electrical control circuit diagram is used to describe the electrical principle of the electrical control equipment and the technical drawings for installation and debugging, including electrical schematic diagram, electrical installation location diagram, electrical installation wiring diagram and electrical installation interconnection diagram.
Electrical circuit diagram
Electrical wiring diagrams are drawings that describe the wiring relationships and principles of control wiring and are divided into electrical schematic diagrams and electrical installation wiring diagrams.
Start-stop control
Classification of electrical schematics:
Main: High current through partial assistance: control, lighting, indication
Drawing rules for electrical schematics:
Main: thick solid line auxiliary: thin solid line
Electrical symbolism:
Usually placed vertically, it can also be rotated 90 degrees counterclockwise. The state of the electrical components in the figure is normal (unpressed, unenergized...)
Positive reversal
Electrical principle drawing method
1, check the line drawing method (common method):
According to the principles from the main to the auxiliary, from top to bottom, from left to right analysis of electrical schematics. More complex graphics can usually be divided into zeros, and the control circuit can be turned into detailed analysis of several independent links. Then, it is strung together as a whole analysis.
2, the logic of algebra
Use logic algebra to describe the working relationship of the control circuit.
chain
The symbols of each part of the electrical components in the electrical schematic diagram are irrelevant to the actual position. According to the principle, the electrical symbols can be drawn at any desired circuit location.
Automatic circulation
RSM series of spiral color mixer are used to mix granulated solid plastic raw material and master batch. It is a large plastic
material mixing equipment and has advantages of big capacity, low energy consumption and high working efficiency. It is an ideal auxiliary equipment for plastic extruding and injecting processing production.
Characteristics
1) Screw blades are welded onto the main axis first. Then they are processed as a whole. Therefore, with high concentricity, the machine will run very smoothly and steadily.
2) Screw blades moving in spirals and cycles makes mixing more even and quickly.3) The parts which may touch raw material are
all made of stainless steel. Easy to clean and avoid becoming rusty.
4) Small horse power, large mixing capacity, high speed, mixing in an enclosed space, even mixing, no leakage.
5) Overload protection on motor and power supply interlock protection device so that it can double protect safety of motor and
workers.
6) Grease injection device and material discharge device are installed at the bottom of machine frame. The bearings are very
durable.
Introduction:
To achieve the aim of mixing material, screw blades are used to generate vortex. Materials are sucked towards mixing screws at
the center of hopper bottom by vortex, and then materials whirl upward to the top and fall down so that the evenly mixing can be fulfilled in a short period.
Features:
All parts in contact with material are made of stainless steel to minimize material contamination.
Vertically mounted blending screw and cylinder ensure even mixing of materials.
Removable top assembly (lid, motor, and control box) for easy cleaning.
0~300 hours auto-stop function.
Equipped with main power switch and safety interlock protective device to ensure operator's safety and no damage to the machine.
Pneumatic slide gate is an optional accessory for mounting at discharge outlet.
Optional suction pipes are available for mounting at the two sides to help material conveying.
