Guangdong Jufeng dual-VSD screw, Panyu Huachuang

Guangdong Jufeng Machinery manufactures oil-injected screw packages in Panyu. The official about text identifies the company as the former Guangzhou Xin Jufeng, sitting in Huachuang Industrial Park at the south of the Pearl River Delta. Building area is published at more than 27,000 square metres, with twelve assembly lines, more than eighty technical engineers, more than one hundred technicians, and a national sales-service net. In 2013 the works was named a Guangdong famous-brand compressor. Those are homepage facts. They are not a kW table.

This listing is not the Jiangsu Jufeng works already on the desk. Same English word, different legal person, different park, different packing list. If the buyer writes only “Jufeng screw, China”, both factories will ask which one. Put Panyu Huachuang and the series on the purchase order before you argue about a canopy photo.

Three series are catalogued. Jufeng two-stage dual-VSD screw is a two-stage oil-injected package with dual variable-speed drives. Jufeng PM dual-VSD screw is the permanent-magnet dual-inverter line the homepage describes: high efficiency in the light-load band, no excitation-current field, power factor that the page says can reach 1, smaller current than an induction motor, unlimited start-stop, and a motor that can be built without the usual high-failure bearing stack. The same block says a permanent-magnet motor of the same volume can raise power by about 30 percent, or the same power can shrink volume and weight. Those sentences are drive-architecture notes from the official page. They are not a licence to invent a JF-xxx SKU, and they are not a measured acceptance test.

Oudefeng belt-drive screw is the third row. It is a separate brand from the same park. Belt-drive is a different transmission, a different maintenance file and a different spare-parts crate from a dual-VSD two-stage Jufeng. Say the brand. A microcomputer control slogan on the Jufeng copy is a controller note, not a remote-monitoring contract.

The official site returned 502 and 500 errors during the fetch for this file, so this dossier leans on the homepage about text that search still holds and on the series list already published for the desk. Product-frame tables from third-party malls are not copied here. Missing ISO class, CE and ASME stay missing. Quotes come from Guangdong Jufeng Machinery. The plant remains the seller.

Write the brand before the drive. A Jufeng two-stage dual-VSD package is not an Oudefeng belt machine and it is not a Jiangsu Jufeng skid. The homepage efficiency claims for permanent-magnet motors are architecture notes; they do not replace a measured specific-power figure on the quotation. Because the official product table was down when this file was written, this desk will not fill the gap with a dealer-mall JF code. Send bar(g), FAD, voltage and the Huachuang park as the works. FOB Guangzhou or Nansha unless the quotation names another port. Twelve assembly lines and a 27,000 m² building figure are homepage scale, not a lead-time promise. The 2013 Guangdong famous-brand title is a provincial award, not CE. Dual-VSD and belt-drive do not share a spare crate even when both leave Huachuang.
