    إعدادات معلمة محول التردد من سيمنز Jan 25, 2024
    ال العاكس سيمنز يحتوي على معلمات إعداد متعددة، لكل منها نطاق اختيار معين. أثناء الاستخدام، غالبًا ما نواجه أن محول التردد لا يمكنه العمل بشكل صحيح بسبب الإعداد غير الصحيح للمعلمات الفردية.طرق التحكم: التحكم في السرعة، التحكم في عزم الدوران، التحكم PID، أو طرق أخرى. بعد اعتماد طرق التحكم، يكون التحديد الثابت أو الديناميكي مطلوبًا بشكل عام بناءً على دقة التحكم.الحد الأدنى لتردد التشغيل: يشير إلى الحد الأدنى للسرعة التي يعمل بها المحرك. عندما يعمل المحرك بسرعات منخفضة، يكون أداء تبديد الحرارة ضعيفًا. قد يؤدي التشغيل المطول بسرعات منخفضة إلى احتراق المحرك. علاوة على ذلك، عند السرعات المنخفضة، يزداد التيار في الكابل أيضًا، مما قد يؤدي إلى ارتفاع درجة حرارة الكابل.الحد الأقصى لتردد التشغيل: بشكل عام، الحد الأقصى لتردد أ تحويل التردد يمكن أن يصل إلى 60 هرتز، وبعضها يصل إلى 400 هرتز. سوف تتسبب الترددات العالية في تشغيل المحرك بسرعة عالية. بالنسبة للمحركات العادية، لا يمكن أن تعمل محاملها بالسرعة المقدرة لفترة طويلة. هل يمكن لدوار المحرك أن يتحمل قوة الطرد المركزي هذه.   تردد الناقل: كلما تم ضبط تردد الناقل، كلما كان المكون التوافقي ذو الترتيب الأعلى أكبر، والذي يرتبط ارتباطًا وثيقًا بعوامل مثل طول الكابل، وتسخين المحرك، وتسخين الكابل، وتسخين محول التردد.   معلمات المحرك: يقوم محول التردد بتعيين الطاقة والتيار والجهد والسرعة والتردد الأقصى للمحرك في المعلمات، والتي يمكن الحصول عليها مباشرة من لوحة اسم المحرك.   قفز التردد: عند نقطة تردد معينة قد يحدث رنين، خاصة عندما يكون صوت الجهاز بأكمله مرتفعاً نسبياً؛ عند التحكم في الضاغط، تجنب نقطة زيادة الضاغط.

    Siemens Motor Performance Apr 07, 2024
    Siemens Motor is a leading global motor manufacturer with over 100 years of experience in motor manufacturing. Siemens motor products cover almost all types of motors that can be used in industrial fields. No matter what load you need to drive, Siemens motors can meet the specific requirements of the system. The higher efficiency level reduces energy consumption and directly saves users costs! High protection level (IP55) ensures safe and reliable use by customers! High cost performance ratio, customers enjoy high-quality and reputable international brand products at a lower price, providing assurance for customer use and indirectly saving costs for users. --Flexible wiring: The junction box can rotate in a direction of 4 * 90 degrees, and customers can specify it at their discretion. It only needs to be specified when placing an order. --Solid component connection: Implementing Siemens motor assembly standards, modular design, modular installation, improving component connection reliability, greatly reducing installation and debugging time, and shortening delivery time. --High performance protection level: All motors are designed with an IP55 protection level, which can be used outdoors or in dusty and humid environments. Users do not need to add additional devices, which does not affect normal use. And it can also provide higher protection levels according to user requirements. --Improving insulation performance and increasing motor service life: All standard motors adopt an F-class insulation system and are evaluated according to B-class insulation, which increases the reliability of motor operation, improves motor service life, and can provide higher insulation levels according to user requirements. --Excellent rotor processing technology: After each rotor is processed, it will be properly protected and coated with protective paint. --Select high-performance bearings and lubricating grease: The bearings are made from well-known manufacturers and customized according to Siemens requirements. The grease is Esso Unirex N3, a new type of lubricating grease that is resistant to high temperatures and not easily volatile, ensuring the continuous and long-term reliable operation of key components; --Wide voltage, wide frequency: The actual voltage used can be within the rated range.
  • Siemens Circut Breaker
    Siemens Circut Breaker Apr 15, 2024
    Compact circuit breaker 3VU13 and 3VU16 circuit breakers are compact circuit breakers with a maximum rated current of 63A. Work according to the principle of current limiting. Can be used for starting, disconnecting, overload and short circuit protection of motors or other loads; 3VU13 and 3VU16 can also be used as motor phase failure protection. When used for motor or equipment protection, the above circuit breakers are equipped with overcurrent instantaneous release and inverse time delay overload release. Due to the overload protection of the starter combination device itself, the 3VU16 used for starter combination only has an overcurrent instantaneous release installed. Circuit breakers and contactors can be combined to form a fuse free combination starting device.
