Zhanggu "Smart" Manufacturing Shines in Pengcheng! Shandong Zhanggu Heavy Equipment Co., Ltd. Shows up in 2026 South China Air Compressor Exhibition, where No.4 Pavilion was ignited by its hard core strength

Spring tide is surging, Pengcheng is about to. The "The 11th South China Air Compressor Exhibition in 2026" will be held in Shenzhen International Convention and Exhibition Center (Bao'an New Museum) from April 1 to 3, 2026. As a leading enterprise in Roots blower industry in China and one of the top 500 machinery manufacturers in China, Shandong Zhanggu makes its appearance in booth K502 of No.4 exhibition hall with multiple energy-efficient "star products" and cutting-edge solutions. In this grand event gathering industry elites, Shandong Zhanggu demonstrates the strong strength and green responsibility of "Zhanggu Intelligent Manufacturing" to the global merchants.

More than 50 years of background, building industry benchmark

Walking into No.4 Hall of Shenzhen International Convention and Exhibition Center, Shandong Zhanggu's booth was crowded with people. The brand color of red and white is particularly striking. "Zhanggu", a gold-character signboard winning the title of "China's Famous Trademark", is shining in the light. Shandong Zhanggu has gone through more than 50 years of brilliant history since its establishment in 1968. As a key fan production enterprise of the former Ministry of Machinery Industry, the Company is not only the main drafting unit of the national standard of roots blower, but also the "invisible champion" of the roots blower industry in China. The year of 2026 is the key year for Shandong Zhanggu to deepen the "Project Energizing Year". Relying on the three industrial platforms of intelligent manufacturing, environmental protection water treatment and new material development and application, Shandong Zhanggu is accelerating the transformation from traditional manufacturing to "manufacturing+service" digital enterprise. This exhibition is not only a display of the products, but also a statement of strength as an industry leader in leading technological innovation.

Suspension technology and high efficiency and energy conservation lead the green future

Under the dual drive of "dual carbon" target and digital transformation of manufacturing industry, high efficiency and energy conservation become the main theme of air compressor industry. In this exhibition, Shandong Zhanggu highlighted its cutting-edge achievements in the field of air compressors and became the focus of field attention.

1.Suspended bearing centrifugal compressor

Suspended bearing centrifugal compressor is definitely the "technology star" on the booth. This product adopts advanced suspension bearing technology and high-speed permanent magnet synchronous motor integrated direct drive structure, combined with multi-stage compression+intercooler+three-way flow impeller precision design, achieving subversive performance breakthrough. Compared with traditional air compressors, our products do not need to increase the gearbox, and the energy conservation rate is more than 20%; at the same time, because of the complete oil-free operation, the output compressed air is 100% oil-free, which is cleaner and more environmentally friendly. "The on-site engineer of Zhang Gu introduced to the customer. In addition, this product also has the advantages of low noise, low vibration, easy installation and maintenance-free, perfectly fitting the dual pursuit of green production and cost reduction and efficiency improvement of modern industrial enterprises. Shandong Zhanggu is helping the low-carbon transformation of the high energy consumption industry by continuously increasing the research and development investment of energy-saving wind turbines, and practicing the manufacturing concept of "harmony and coexistence between human and nature".

2.Gearbox high-speed centrifugal compressor

Gearbox high-speed centrifugal compressor

The impeller profile is advanced, with high efficiency and more energy saving

The impeller is designed based on the three-way flow theory, and the insulation efficiency of high-speed centrifugal compressor is high.

Wide flow regulation range, applicable to various working conditions

The fan flow can be adjusted by frequency conversion, inlet guide vane IGV and outlet adjustable diffuser OGV, with wide adjustment range and high efficiency under non-rated working conditions. The anti-surge device equipped can effectively prevent the compressor from surging.

Diversity of transmission media

The compressor can transmit a variety of media, and meet the transmission requirements by replacing the impeller, volute, seal, etc.

The blower is compact in structure and small in volume

The assembled integral structure is adopted. The compressor body is assembled on the housing of the gear speed-up gearbox. The lubricating oil system, motor and gear speed-up gearbox are arranged on the common base, which serves as the oil tank. Low vibration, high reliability and low overall noise of rotor after strict dynamic balance. Small moment of inertia of rotor, short startup and shutdown time of unit, no need of elevated oil tank and accumulator. Compared with other types of fans with the same flow and pressure, the energy consumption is small, the weight is light and the floor area is small. The fan structure is advanced and reasonable, with less vulnerable parts and convenient installation, operation and maintenance. The bearing vibration, temperature rise, inlet and outlet pressure, temperature, anti-surge control, startup interlock protection, fault alarm, lubrication system oil pressure, oil temperature control, etc. of the whole machine are all controlled by programmable logic controller, so that the operation of the whole machine can be monitored in real time. Less vulnerable parts and convenient daily maintenance.

High intelligence level

A series of monitoring and control of bearing vibration, temperature, inlet and outlet pressure, temperature, anti-surge control, startup and shutdown interlocking protection, fault alarm, lubrication system oil pressure, oil temperature, etc. of the whole machine are controlled by programmable logic controller, and transmitted to "Zhangguyun" intelligent cloud platform in real time, so that users and project engineers can monitor the equipment operation in real time.
