  At Quanwei Machinery (Jiangsu) Co., Ltd., we believe that a company’s strength lies not only in its high-quality products but also in its respect for traditions and care for its team. As one of China’s most important traditional festivals, Qingming Festival (Tomb-Sweeping Day) is approaching, and we are pleased to share the origins and customs of this meaningful festival, along with our company’s holiday arrangement, to convey our gratitude to every employee and partner.         Qingming Festival, usually falling on April 4th or 5th each year, has a history of over 2,500 years. Its origin can be traced back to the Spring and Autumn Period, initially as a festival to honor Jie Zitui, a noble man known for his loyalty and selflessness. Over time, it has evolved into a comprehensive festival that combines reverence for ancestors, commemoration of the deceased, and celebration of spring’s arrival. It is a time when Chinese people express their nostalgia for loved ones and embrace the vitality of the new season, reflecting the traditional values of filial piety, gratitude, and harmony with nature.     There are many time-honored customs associated with Qingming Festival, which have been passed down through generations and are still practiced today. The most core custom is tomb-sweeping: families gather to clean the tombs of their ancestors, offer flowers, fruits, and other sacrifices, and pay their respects to express their remembrance and gratitude. Another popular custom is spring outing, as Qingming coincides with the blooming of flowers and the recovery of all things—people go outdoors to enjoy the fresh air, appreciate the beautiful scenery, and feel the vitality of spring. Additionally, eating qingtuan (a glutinous rice cake wrapped in mugwort leaves) is a traditional food custom, symbolizing purity, peace, and the hope for a good harvest.     At Quanwei Machinery, we attach great importance to inheriting traditional culture and caring for the work-life balance of our employees. We understand that Qingming Festival is a precious time for our team members to reunite with their families, honor their ancestors, and enjoy the spring scenery. Therefore, we are pleased to announce that our company will observe a 2-day holiday for Qingming Festival.      While we take time to honor traditions and rest, we also want to express our sincere gratitude to our global partners for their long-term trust and support. Quanwei Machinery has always adhered to the concept of "integrity, innovation, and people-oriented", and we believe that respecting traditions and caring for our team will enable us to move forward more steadily and provide better services to our partners around the world.     As we celebrate Qingming Festival, we look forward to the arrival of spring, the renewal of all things, and the continued growth of our cooperation with you. May this festival bring peace, happiness, and warmth to you and your family. We will return to work with full energy after the holiday, continuing to provide professional and reliable pneumatic solutions for the global manufacturing industry.

  As the first ray of morning sunlight breaks through the horizon and spills over the factory campus of Quanwei Machinery (Jiangsu) Co., Ltd., the quietness of the early hours is gently broken by the sound of workshop doors sliding open. One by one, our skilled workers, dressed in neat work uniforms, walk into the production workshop with a sense of purpose and dedication. They greet each other with a simple nod, a silent acknowledgment of the day’s shared mission—crafting reliable, high-quality screw air compressors that live up to the trust of our global customers. This is not just a daily routine; it is a commitment to excellence that has been woven into the fabric of our company’s culture, day after day, year after year.         The workshop soon comes alive with the steady hum of machinery, the crisp clink of tools, and the focused energy of our team. Every worker takes their position with meticulous care: some carefully inspect the raw materials and components, running their fingers over the surfaces to check for even the tiniest imperfection; others operate precision equipment with steady hands, adjusting dials and controls with the kind of expertise that only comes from years of practice; still more assemble each part with patience, ensuring that every bolt is tightened to the exact specification, every connection is secure, and every detail is in place.

Before moving on to the next step, they double-check, triple-check, and even verify with their colleagues—ensuring that every component is up to standard, every assembly is precise, and every test is passed with flying colors.     You can see this dedication in their eyes: the concentration as they measure and adjust, the care as they handle delicate parts, the satisfaction as they complete a perfect assembly. Sweat glistens on their foreheads as they work tirelessly, not because they have to, but because they want to. They know that their hard work is not just for themselves, but for the reputation of Quanwei Machinery, and for the trust of the customers who rely on our products. Even when the work is repetitive, even when the hours are long, they never lose sight of their goal—to build air compressors that are stable, durable, and reliable, machines that our customers can count on day in and day out.     Quality control is not just a process at Quanwei; it is a mindset that every worker embodies. From the moment raw materials arrive at our factory to the final inspection before shipment, every link in the production chain is subjected to strict scrutiny. Our workers do not just follow procedures—they uphold them, refine them, and take ownership of them. If a potential issue is spotted, no matter how minor, they stop, address it, and ensure it does not affect the final product. This level of attention to detail is what sets us apart, and it is what makes our air compressors stand out in the global market.     We often say that a company’s strength lies in its people, and at Quanwei Machinery, this could not be more true. Our production team is the backbone of our business—skilled, dedicated, and committed to excellence. They are the ones who turn designs into reality, who transform raw materials into reliable machines, who ensure that every product that leaves our factory meets the highest standards of quality. Their sweat, their focus, their unwavering commitment to doing things right—these are the ingredients that make Quanwei a trusted name in the pneumatic solutions industry.     As the day draws to a close, the workshop gradually quiets down. Our workers finish their tasks, clean their workstations, and reflect on the day’s achievements. They leave the factory knowing that they have done their best, that they have contributed to something meaningful, and that their hard work will help our customers succeed. This is the spirit of Quanwei—hard work, dedication, and a relentless pursuit of quality.     To our global customers: every air compressor you receive from Quanwei is not just a machine.

Dalam beberapa tahun kebelakangan ini, kekerapan berubah-ubah pemampat udara telah memainkan peranan penting dalam pasaran pemampat udara kerana sifat penjimatan tenaga yang baik. Walaupun begitu, ramai pengguna masih tidak mengetahui perbezaan antara pemampat udara frekuensi berubah dan pemampat udara frekuensi kuasa. Sebenarnya, perbezaan utama antara pemampat udara frekuensi berubah dan pemampat udara frekuensi industri adalah seperti berikut:1. Tekanan udara stabil.Pemampat udara frekuensi berubah mengambil kesempatan daripada ciri peraturan kelajuan tanpa langkah penukar frekuensi. Ia boleh bermula dengan lancar melalui pengawal atau pengawal selia PID di dalam penukar frekuensi. Ia boleh melaraskan tindak balas dengan cepat kepada situasi di mana penggunaan udara sangat berubah-ubah.2. Tiada kesan pada permulaan. Penukar frekuensi itu sendiri mempunyai fungsi pemula lembut. Arus permulaan maksimum adalah dalam 1.2 kali arus undian, manakala kekerapan kuasa bermula biasanya lebih daripada 6 kali arus undian. Berbanding dengan frekuensi berubah-ubah, impak permulaan adalah sangat kecil. Kesan ini bukan sahaja pada grid kuasa, tetapi juga pada keseluruhan sistem mekanikal akan dikurangkan dengan banyak.3. Kawalan aliran berubah. Penukar frekuensi pemampat udara frekuensi berubah melaraskan kelajuan motor dalam masa nyata mengikut penggunaan udara sebenar untuk mengawal isipadu ekzos. Oleh itu, pemampat udara frekuensi berubah boleh berfungsi dalam julat isipadu ekzos yang agak luas.4. Bekalan kuasa AC mempunyai kebolehsuaian voltan yang baikOleh kerana teknologi pemodulasi berlebihan yang digunakan dalam penukar frekuensi, apabila voltan bekalan kuasa AC rendah sedikit, ia masih boleh mengeluarkan tork yang mencukupi untuk memacu motor; apabila voltan lebih tinggi sedikit, ia tidak akan menyebabkan voltan keluaran ke motor menjadi terlalu tinggi;Untuk majlis penjanaan sendiri, pemacu frekuensi berubah-ubah boleh menunjukkan kelebihannya dengan lebih baik;Menurut ciri-ciri motor VF (pemampat udara frekuensi berubah-ubah beroperasi di bawah voltan terkadar dalam keadaan penjimatan tenaga), kesannya jelas untuk tapak dengan voltan grid rendah.5. Bunyi yang rendah. Kebanyakannya keadaan kerja sistem penukaran frekuensi adalah lebih rendah daripada kelajuan undian. Bunyi dan haus mekanikal hos dikurangkan, dengan berkesan memanjangkan masa penyelenggaraan dan hayat perkhidmatan.
