When the atmospheric conditions and medium are varied, the relative performance conversion calculation will be different. We can re-design in accordance with the requirement of users to adapt to different working conditions. There are two cooling methods for air suspension centrifugal blower: self-circulating water cooling and forced air cooling. If you have special requirements on the cooling mode, please tell us in advance.
Foil Bearing Technology
Foil bearing has physical contact between the rotor and the bearing before starting, the relative movement of the rotor and the bearing generates air pressure when starting, when the rotor rotates, the speed of the air around the rotor can be converted into pressure energy, and the air pressure makes the rotor float when the rotor reaches a certain rotation speed and plays a lubricating role.
Shandong Zhanggu independent research and development the fourth generation of multi-simply supported beam dynamic pressure air suspension bearing, can reach 255,000 times of start and stop life, 20 years of durable operating life; Meet ISO 16750-3 automotive-grade random vibration and 25G acceleration impact vibration standards; Effectively solve the traditional mechanical bearing transmission system problems of low efficiency, short life, requires regular maintenance and lubrication.

Using environment:
Cooling water requirements for plastic mould. The low temperature water will be transferred to the mould by water pump, the inner heat will be taken away by the surface heat transfer principle to achieve the cooling purpose.
Cooling water temperature: 8℃
Comparison:
Original unit adopt six sets of scroll compressor, five sets at full load throughout the year and one standby. The cooling water demand of the entire process line can't be meet under the high load, low efficiency and high maintenance costs.
Current unit using XECA200RT Air Foil Bearing Refrigeration Compressor. It could meet the cooling water requirements under the full load in summer and will running on low power in off-season. The advantage is high efficiency, stable running and low maintenance costs.
