The use of Roots vacuum pump requires the maintenance of power, so it will be wired before using the equipment, but when installing the equipment cable, it must be carried out in strict accordance with the specified operating requirements, so as to ensure the use of the equipment and avoid causing the equipment. Adverse effects. Let's follow the editor to briefly understand and see what its wiring methods are!
1. When wiring, pay attention to pressing half of the circle when wrapping with polyester insulating tape, and wrap 8-12 layers. After wrapping, use plastic tape to wrap two layers for strength; then, when wiring, To strip the copper core of its cable about 30-35mm long, wipe the copper wire clean with emery cloth to make it shiny, and also peel off the copper wire of the external three-core cable by 30-35mm, and wipe it clean with emery cloth.
2. In the wiring of Roots vacuum pump, the three-core cable and the copper wire part of the external cable will be plugged in, and then tied with a thin copper wire. The remaining part is cut off and flattened with scissors to prevent hands from being tied; When wiring, the three wire ends of the equipment should be soldered firmly with solder. The surface of the welding head is required to be smooth, free of burrs and false welding. If the welding is not strong or not smooth, the vacuum pump should be re-welded until the requirements are met.
3. In addition, use plastic tape to wrap the three wires together, wrap two layers, one layer exceeds the end of each wire insulation layer by more than 50mm, and the second layer exceeds the end of the layer by 50mm. After wrapping, take a basin of cold water to wrap it up. The thread ends are safely immersed in water. After 12 hours, the insulation cannot be lower than 50 megohms with a 500V megohmmeter, otherwise it should be re-wrapped until the requirements are met.
4. The grounding wire needs to be wrapped according to the requirements of the submersible cable wiring process; after the wire is connected, the insulation resistance should be continuously measured while down the well to prevent the cable insulation from being broken by the well wall. If it is found that the insulation level has dropped to 0.5 trillion rapidly When it is below Europe, the unit must be brought up to detect the cause.
To sum up, the editor tells: a brief introduction to the related knowledge of the wiring method of Roots vacuum pump, I hope you can learn more through the introduction of the above editor.
