Products

RR series roots blower, vacuum pump
RR series roots drum and vacuum pump are produced by our company with the latest design and manufacturing technology introduced from Japan.
Product features:
1. There are many varieties and specifications, including positive pressure, negative pressure, dry type and wet type. It has the characteristics of dense flow distribution and convenient user selection.
2.The inlet small clearance bearing is specially customized to ensure the axial positioning of the fan blades is reliable and easy to adjust.
3. The impeller adopts the whole cast structure, with high blade accuracy (no dressing during assembly), which makes the impeller have complete interchangeability.
4, the shaft seal in addition to the labyrinth seal form, but also with mechanical seal, packing seal and other forms of sealing, to meet the needs of different media transport.
ZG series roots blower/vacuum pump
Product features: 1. The housing is designed with special structure to ensure reliable operation under high pressure and reduce operation noise;
2. The fan impeller and shaft adopt the integrated structure with good rigidity to ensure high pressure, high flow and smooth operation of the fan at high speed;
3. The fan fuel tank is made of aluminum alloy with air cooling structure, and no cooling water is needed for the single-stage pressure of 98kPa;
4. Intensive unit design, compact structure, belt tensioning adopts self-tensioning structure, easy to use and maintain;5. The main fan can be both vertical and horizontal, which can easily replace foreign models;
6. Adopt precise hard tooth surface helical synchronous tooth, no key connection, reliable positioning.
ZW series roots blower/vacuum pump
Product features:
1, high speed, the highest speed up to 5170r/min, high efficiency, small volume, light weight, compact structure, easy to use and maintenance.
2. Adopt advanced three-bladed structure, with high area utilization coefficient, small air pulsation, stable operation and low noise.
3, the use of precision hard tooth surface straight tooth synchronous gear, keyless connection, reliable positioning, low noise, high strength, long life.
4. The drive end is lubricated with grease, and the gear end is lubricated with oil.
5. Aluminum alloy fuel tank, good cooling effect, air cooling structure, no cooling water for 58.8kpa boost.
SSR series roots blower
SSR series is a new three - blade roots blower developed by sino - Japanese joint venture.
Product features:
1, the use of advanced driving gear, not only to prolong the life, but also to achieve low noise.
2. The inlet and outlet of the fan does not open or close at an instant like the old-style fan, so the operation sound is very small and there is almost no exhaust wind pulsation.
3. The output air is clean without any oily dust.
ZR series large roots blower, vacuum pump
Features: 1, impeller only with the near involute line, advanced and reasonable, high efficiency.2. The main parts are processed by machining center and numerical control equipment, and the gear adopts grade 5 precision, which makes the product high precision and reliable operation.
3. The oil tank adopts new structure such as oil tray, which can dissipate heat well. When the boost is 49kpa, no cooling water is needed, and the use cost is small.4, the housing, wall board adopts the horizontal structure, convenient maintenance.Main applications: pressure swing adsorption air separation oxygen air transport and exhaust gas extraction.Coal chemical industry (small chemical fertilizer) industry conveying half - water gas and water gas desulfurization fan and so on.
B series single-stage high speed centrifugal blower
The impeller of single-stage high-speed centrifugal blower is designed by ternary flow theory, with high variable efficiency, which can be applied to municipal sewage treatment and aeration, power station circulating fluidized bed boiler vulcanization, petrochemical oil and gas desulfurization, papermaking, metallurgy, pharmaceutical, industrial gas pressurization and other industries.The development of single-stage high speed centrifugal blower conforms to the national policy of environmental protection and energy saving.The single-stage high speed centrifugal blower has been widely used in the field of electric desulfurization and oxidation fan.
Multi-stage centrifugal blower (MC series, C series)
Multi-stage centrifugal blowers are widely used in sewage treatment, power, metallurgy, chemical industry and other industries due to their characteristics of easy flow regulation, low noise and easy elimination.The new c-series multi-stage centrifugal Blower not only embodies the years of theoretical and design experience of xi 'an jiaotong university, but also includes many years of fan manufacturing experience of Shandong Zhangqiu Blower Co.,Ltd. It is the latest domestic product integrating many advanced technologies.
Magnetic suspension centrifugal Blower
Performance characteristics: energy-saving and efficient, high-speed permanent magnet motor and efficient ternary flow impeller drive directly coupled;With low noise and self-balancing technology, the vibration of magnetic suspension bearing is one order of magnitude smaller than the traditional bearing without friction.At the same time, active shock absorption design, stable operation, small vibration, fan noise around 80db;Maintenance-free, integrated design, pry structure, convenient installation, start and stop with one key.Intelligent control.Application: suitable for sewage treatment, food and medicine, petrochemical industry, leather printing and dyeing, metallurgy, prevention and control, cement building materials, etc.
Air suspension centrifugal blower
Features: 1, high efficiency air bearing, permanent magnet brushless dc motor and frequency conversion system, aluminum alloy precision casting high precision impeller.2. The gearbox speed increaser and coupling are not required. It is directly driven by a high-speed motor, and the motor adopts a frequency converter to adjust the speed.The impeller is directly combined with the motor, and the shaft is suspended on the active air bearing controller, featuring high efficiency, energy saving, low noise and reliable operation.3. Compact integrated design, small size, energy saving and convenient maintenance.Main application: sewage treatment and other industries.
