The air suspension high-speed centrifugal fan designed and manufactured by Nantong Rongheng Environmental Protection Equipment Co., Ltd. is a domestic brand of fan equipment with completely independent intellectual property rights. The technical advancement of its products and the self-design and self-manufacturing of core components have the following advantages over similar products imported from abroad and magnetic levitation products:Motor advantages: Rongheng Air suspension fan adopts quadrupole permanent magnet synchronous motor, motor efficiency >97%, stable operation, higher reliability; Other brands of fans usually choose a bipolar motor, the general efficiency is about 95%;Inverter advantages: Rongheng fan uses a higher frequency inverter, usually 1000HZ, 1600HZ frequency inverter, higher technical performance, stable and reliable operation; Imported fans generally use 400HZ, 600HZ frequency converter, its technical performance and operating stability is poor;Inductance advantage: The Rongheng air suspension fan is equipped with a filter system, which greatly improves the immunity of the product to the power supply system, making it more suitable for the use of different power grid calls, and has the advantages of stronger adaptability to the working environment and more stable system work; Other fans generally do not have this configuration;Impeller advantages: Rongheng fan uses high-efficiency five-axis milling compressor impeller, which has a wider range of high-efficiency performance, strong ability to adapt to selection, and high impeller strength, long life and other advantages; The imported fan usually uses the cast impeller, whose performance is reduced, the airflow noise generated by the impeller will be larger when it works, and the fatigue resistance is lowBearing advantages: Rongheng independently designed and manufactured air suspension bearings with performance, controllable quality and high reliability. Compared with other outsourced bearing manufacturers, Rongheng has the advantages of a short production cycle, high supply efficiency and guaranteed product delivery. Compared with magnetic suspension bearings, it has the advantages of simple structure, low cost and high reliability. Noise advantage: Rongheng fan has made an active noise reduction design for noise reduction, and adopted engineering noise reduction measures for each noise source so that its noise can be reduced to 75 decibels; The noise of other fans is generally above 80 decibels, and the noise control advantages of Rongheng fan are obvious.

The high-temperature solid lubricant technology used by Rongheng air bearings can be switched on and off more than 20,000 times continuously under high/low-temperature conditions, which is a semi-permanent bearing. The air bearing has no mechanical contact, no lubricating oil system, no regular maintenance, and can achieve long-term stable operation. Air bearing technology: First applied by the National Aeronautics and Space Administration (NASA), air bearing technology has been normally used in the cooling system of Boeing aircraft in the United States for nearly two decades, and the technology is very mature.

The impeller efficiency can reach 92%, and the fan compression efficiency (including the vortex shell, impeller and diffuser) can reach 84%. When the working condition changes, the efficiency of the blower decreases by less than 2%. Advanced production technology: the impeller is processed by a five-axis linkage machining center; The material is made of aviation aluminum alloy, which has the characteristics of high strength, small inertia and high reliability. Connection form: direct connection between impeller and motor, high efficiency; Impeller service life of more than 20 years;

When the external load changes (high load/low load/no load), the inverter automatically adjusts the motor speed and changes the pressure/flow rate to ensure the operating condition. According to the change in the working environment, with the inverter can save energy 15% to 40%.The motor controller (inverter) can also accurately adjust the speed of the motor in the case of a high-temperature environment to achieve an accurate adjustment function.The frequency converter is used with the permanent magnet synchronous motor, with low noise, no vibration, and low starting current (starting at 5% of the rated current). The efficiency of the inverter is 97%.

1. High efficiency, significant energy saving; Low noise, optimized working environment high-efficiency impeller and the ultra-high speed motor are directly connected through the air bearing to remove the transmission gearbox and lubrication system, no mechanical contact, no vibration, low noise operation, no need to take cumbersome sound insulation measures. BLDC motor and frequency conversion speed control system is used to adjust the speed to control the flow and pressure and maintain a high efficiency within the range of the working flow of the fan.

2. Save space and reduce investment in auxiliary facilities air room area; The equipment is light in weight, the foundation construction is simple, and the convenient arrangement can be selected according to the needs, such as the blower room can be directly set up on the aeration pool, which can save pipeline investment and reduce pipeline resistance loss.

3. Simple operation and high degree of automationThe fan itself self-checks the speed, pressure, temperature, flow rate, etc., and has the function of preventing surges, etc., which can realize unmanned operation; In the working area of the fan, the output of the fan air volume and pressure is freely adjusted according to the external control signal. The fan does not need an additional local control cabinet and soft start cabinet; The fan itself integrates the local control system; The main control panel set up in the air room can automatically and continuously adjust the pressure, flow, control opening, and problem alarm through the computer CPU, to realize the automatic control operation of single and multiple sets at the same time. It can also be controlled from a remote central control room. After simple training of the relevant technical personnel, according to the procedure Settings of the operation manual, the fan can be automatically put into operation and achieve unmanned operation.

4.No lubricating oil, no maintenance, and high reliability of equipment. Due to the adoption of the ultra-high speed permanent magnet synchronous motor directly connected impeller and dynamic pressure air suspension bearing technology, the system failure due to transmission and oil lubrication is eliminated; The use of air suspension bearing, equipment operation without mechanical friction, no lubricating oil lubrication, eliminating maintenance; The key parts are made of materials; Through standardized fine production, to ensure stable and equipment performance, high reliability, long equipment life.
