　　 RB-72S-5/7.5KW Double bladed Vortex Air Pump Double stage High pressure Fan Double turbine Blower Full air

　　 Double bladed vortex fan

　　Vortex air pumpMainly used in the sewage treatment industry, also known as aeration blower, some industries also call aeration blower. It is mainly connected to the pipeline at the outlet of the blower to the bottom of the sewage treatment tank for aeration, so that the biological active substances in the sewage treatment tank can fully contact with the substances in the sewage, thereby achieving the purpose of pollution removal. Special blade design, high pressure, large air volume, low noise, long service life; Special air volume control damper, with high stability in air volume control and easy operation; Complete range of styles, abundant inventory, and timely delivery.

　　 Vortex air pumpThe selection table provides selection data based on the operating characteristics, air volume, and pressure changes of the air pump, which has high selection value. Generally, when selecting, we refer to the selection table of the fan, and find the point of the required air volume corresponding to the point of the required pressure, so as to obtain a cross point. The air pump above the entire point can usually meet your on-site needs.

　　Vortex air pumpworking principle

　　When the impeller rotates, due to the centrifugal force, the wind vane drives the gas to move forward and outward, forming a series of spiral movements. The air between the impeller blades accelerates and rotates in a spiral shape, squeezing the gas outside the pump body into the side groove (sucked in through the suction port). When it enters the side channel, the gas is compressed and then returns to accelerate and rotate between the impeller blades again. When air passes through the impeller and side groove along a spiral trajectory, each impeller blade increases the degree of compression and acceleration. As the rotation progresses, the kinetic energy of the gas increases, further increasing the pressure of the gas passing through the side channel.

　　Vortex air pumpstructure

　　1. Impeller: Adopting a gradually opening linear surface for high volume utilization. 2. Bearing: 3000 type double row radial spherical roller bearings are selected as the positioning end near the coupling end. 32000 type single row radial short cylindrical roller bearings are selected as the free end near the gear end to adapt to the axial displacement of the rotor during thermal expansion. 3. Body: Composed of a casing and left and right wall panels. The left and right wall panels, as well as the bearing seats and sealing parts installed inside the left and right wall panels, can be interchangeable. 4. Base: Both small and medium-sized fans are equipped with a common base, while large fans are only equipped with a fan base for easy installation and debugging. 5. Transmission mode: mainly through direct coupling of couplings. If performance specifications require it, the method of variable speed with triangular pulleys can also be chosen. Elastic couplings are selected for the coupling, which can alleviate impact and compensate for a small amount of axis deviation. Large flow fans can also be driven by steam turbines or other types of motors, in addition to electric motors.

　　Vortex air pumpFeature Introduction

　　1. Aluminum die-casting impeller: generates stable airflow and efficient flow rate; 2. Dynamic balancing impeller: smoother operation, no vibration during operation; 3. Double covered bearings: prevent grease leakage and increase the reliability of operation; 4. Dustproof shaft seal: prevents dust intrusion and extends bearing life; 5. The combination of motor spindle and impeller inlay: without the need for connectors, belts, or gears, there is no concern of breakage or wear; 6. 50/60HZ and wide voltage design: reduces the manufacturer's inventory demand for 220V to 660V voltage; 7. High performance cooling fan: effectively cools the motor and air pump, enabling them to operate efficiently and with low noise; 8. Embedded thermal protector (optional): more effective in preventing motor overheating and enhancing product reliability; 9. Miniaturization design: allowing users to use and install space more effectively; 10. Detachable pipe fittings (optional): easier to install.
