Corn continuous vacuum packing electrical schematic drawing of the principle

corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packaging machine commonly used electrical control circuit diagram of electric schematic diagram, electrical wiring diagram of layout and installation, electrical principle diagram is said system, subsystem, complete sets of equipment, equipment in the practical circuit and the electrical components such as wire connection relations and the working principle diagram. Don't have to consider when drawing electrical schematic diagram of the project entity the size, shape or position. Electrical principle of the graph is to understand, prepare the connection file, test, the influence of the circuit malfunction, installation and maintenance to provide the necessary information.



corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packing electrical schematic diagram of simple structure and distinct, clear relationship, is suitable for the analysis and study the working principle of the circuit and as a basis for the other electrical diagram, in the design department and production site for a wide range of applications. Draw the schematic diagram of the electrical principles mainly has the following several aspects:

a, electrical schematic drawing standard

corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packing electrical schematic diagram of all the components should be used in the unified regulations of the state of graphic symbol and text symbols.

2, electrical schematic diagram of the

corn continuous vacuum packing electrical schematic drawing of the principle. Continuous vacuum packing electrical schematic diagram of corn consists of main circuit and auxiliary circuit. Main circuit from the power source to the circuit of the motor, including switch, fuse, thermal relay, contactor, the main contact heating components and the motor and so on. Main circuit with coarse thread drawing left or above in electrical principle diagram. Auxiliary circuit including the control circuit, lighting circuit, signal circuit and protection circuit, etc. They consist of electromagnetic coil of relay, contactor, relay, contactor, auxiliary contacts, control button, contactor, fuse, lights and other control components and other components of the control switch, thin lines are used to draw on the right side of the electrical schematic diagram or below.



3, the power cord for the

corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packaging electrical schematic diagram of the dc power supply with horizontal line drawing, usually forward voltage of the dc power supply in the upper part of the electrical schematic diagram, draw negative phase voltage in the electrical schematic diagram below. Three-phase ac power supply cord concentration level picture in the upper part of the electrical schematic diagram, phase sequence from top to bottom to line up with the L1, L2, L3, neutral line ( N line) And protection of ground wire ( PE line) Under the line. Main circuit is perpendicular to the power line drawing, the control circuit and signal circuit is perpendicular to the draw between two levels of the power cord. Power components ( Such as the contactor, relay coil, electromagnet coil, lights, lights, etc. ) Directly with the level below the power cord, control contactor pick up at the top level between the power cord and power components.

4, electrical schematic drawing of electric components

corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packaging of electrical schematic diagram of the electrical components are not painted the appearance of the actual figure, just draw the live parts, the same electrical components on different live parts is according to draw in the circuit connections, but need to be stipulated in the national standard of graphic symbol to draw, and use the same text symbols. For several similar electrical appliances, after said name text symbols combined with digital serial number, to show the difference.

5, electrical principle diagram drawing of electrical contact

corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packing electrical schematic diagram of each component in the contact state are calculated by contact without external force or an unpowered natural state, draw the contactor, electromagnetic relay according to the electromagnetic coil electricity contact state draw: the size of the control button, trip switch contact press is not affected by external force when the state of the draw: for circuit breaker and switch electric contact is drawn according to the off state. When electrical contact graphic symbol vertically, with & other Left on the right off & throughout; The principle of drawing, that is, perpendicular to the left of contactor for normally open contacts, perpendicular to the right of the contact for the normally closed contacts: when the symbol is placed, to & other; The closed under open & throughout; Principle, namely of the contact on the top of the horizontal line is normally closed contacts, below the horizontal line of contact for normally open contacts.



6, the layout of the electrical schematic diagram

corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packing electrical schematic diagram of the function layout, namely the same function of the electrical components together, as far as possible according to the action sequence from top to bottom or from left to right on the principle of drawing.

7, line connection point, draw the intersection of the

corn continuous vacuum packing electrical schematic drawing of the principle. In corn continuous vacuum packaging machine circuit diagram, for the need to test and external wire terminals, use & other The hollow circle & throughout; Said. Have a direct electrical contact wire connection, use & other; Solid round & throughout; Said: no direct electrical contact wire junction is not painted black dot. In the electrical schematic diagram to avoid crossing lines.

eight, electrical schematic drawing requirements

corn continuous vacuum packing electrical schematic drawing of the principle. Corn continuous vacuum packing electrical schematic drawing to distinct, of all electrical components and the arrangement of the contact to be reasonable, both to do used components, contact less, less energy consumption, and to ensure the reliable operation circuit, saves the wires and installation, maintenance is convenient.
