Taizhou sewage treatment fan manufacturer supplies sewage aeration high-pressure blower RB-72S-4 bipolar vortex fan

Double stage high-pressure fan That's what we usually sayDouble bladed high-pressure fanBecause the product consists of two impellers, it has a higher flow rate and pressure compared to a single-stage high-pressure fan.

The two-stage high-pressure fan is a vortex air pump that can be used for both blowing and suctionThe special blade design of high-pressure fans has the characteristics of high pressure, large air volume, low noise, and high temperature resistance. The high-voltage fan has strong insulation performance, easy installation, high stability, and the gas passing through is oil-free and dry. The exhaust standard can meet the quality requirements. The generation of high pressure and high suction is due to the unique design of the impeller. The impeller edge of a two-stage high-pressure fan has multiple blades. When the impeller rotates, due to centrifugal effect, the air in the two blades is quickly moved towards the outer edge direction, converted into energy, and the wind pressure is quickly superimposed, forming high pressure or increasing the movement speed. When the air is reintroduced into the impeller by the air duct, it will be accelerated again. Due to the multiple blades of the high-pressure fan transmitting energy, the wind pressure is rapidly overlapped, resulting in high pressure or high suction force.

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.
