Based on ANSYS soft-axis crystal pulling system swing analysis, artificial crystals are core raw materials required for the solar photovoltaic power generation industry and semiconductor industry. The crystal pulling furnace is a special equipment for manufacturing artificial crystals, and most of the current crystal pulling furnaces use the soft-axis pulling system. Due to the constraints of the liquid/solid phase transition law, the crystal pulling system in the actual work requires not only rotation but also upward movement, while maintaining stable speed and good neutrality, without蠕动 and swing. The swing of the pulling system can cause changes in the micro-diffusion layer during growth, resulting in variations in the effective separation coefficient, leading to radial inhomogeneity in the micro-doping concentration distribution, causing instability in the convection condition, and leading to changes in the supercooling degree of the solid-liquid interface during growth, providing conditions for dendrite growth [1], which can seriously affect the inherent quality of the single crystal. Therefore, avoiding the swing of the pulling system is one of the key points in the structural design of the crystal pulling furnace. In production practice, it has been found that the soft axis of the pulling system of a certain type of crystal pulling furnace shows significant swing when the working speed is close to 13~14 r/min, which has been restricting the quality of crystal growth and the improvement of production efficiency. Although many solutions have been proposed before, their effects have been insignificant. This paper proposes to use the finite element analysis method to analyze the pulling system of the crystal pulling furnace, identify the causes of the swing of the soft axis of the pulling system, and recover sapphire crystal furnaces, polysilicon ingot furnaces, crucible crystal pulling furnaces, polycrystalline crystal furnaces, horizontal crystal furnaces, crystal pulling furnaces, acquisition of Czochralski crystal pulling furnaces -85/90/95/100 models, and a complete set of single crystal recovery and lifting equipment, molecular pump recovery, vacuum pump recovery, vacuum flowmeter recovery, PLC programming recovery, control panel recovery, ion pump recovery, turbo molecular pump recovery, screw vacuum pump recovery, swirl high vacuum pump recovery, (4) electrical hardware setup, the electrical cabinet layout of this system uses modular centralized management, connections between modules are simple, and individual modules can be repaired while energized. Motor protection is facilitated by the use of air switches and wire bonding methods for operation and maintenance. At the same time, the main electrical points can be simply checked on the terminal board. The overall cabinet layout is reasonable and simple, with a dual-color audible and visual alarm light for prompts.

There are many methods for calculating cable current-carrying capacity in the electrical industry, and there are several commonly used mnemonic phrases. For example: "Below ten, multiply by five and add two; between twenty-five and thirty-five, multiply by four and subtract three; between seventy and ninety, multiply by five and add half; for cables through pipes, at eight to nine degrees, multiply by nine and then subtract eight to nine percent; for copper wire, upgrade the calculation; for bare wire, add half." As for cables: "Below two and a half, multiply by nine; above that, subtract one for each subsequent size. Multiply thirty-five by three and a half, and then subtract half a point for each pair. If conditions change, make calculations and adjust; at high temperatures, reduce copper to ninety percent and upgrade. For cables through pipes, the number of pipes is two, three, or four; at eighty, seventy, and sixty percent, the full load current is achieved." Cable professionals are likely familiar with the meanings of these mnemonics. Those who are not can search online; no further explanation is provided here. From these mnemonics, one can see that the thicker the cable's cross-sectional area, the lower the current-carrying capacity per square unit.

The measurement selector switch indicator aligns with the meter scale. It is printed in three colors: red for AC, green for transistors, and black for the rest. The MF47 multimeter has four test lead sockets. The top left corner of the panel features positive and negative test lead sockets, with the convention of inserting the red test lead into the positive socket and the black test lead into the negative socket. The bottom right corner has a 2500V socket and a dedicated socket. When measuring 2500V AC/DC voltage, the positive test lead should be inserted into the 2500V socket. For DC current measurements, the positive test lead should be inserted into the socket. The upper right corner of the bottom panel is the Ohm range zero adjustment knob, used to calibrate the "0Ω" indication on the Ohm range.

Load for 380V working voltage is about 2A per kilowatt. After selecting the appropriate conductor with a safe current-carrying capacity for each distribution circuit, you can ensure circuit safety by matching the trip current value of the circuit breaker or residual current circuit breaker to the safe current-carrying capacity of the conductors. Below, I provide a reference for the common copper-core wire safe load power for single-phase 220V household distribution; the first number is the cross-sectional area of the copper-core wire in square millimeters, and the second number is its safe load power in kilowatts. 1 square millimeter is about 1.3 kilowatts. 5 square millimeters is about 2 kilowatts. 5 square millimeters is about 3.5 kilowatts.
