HC-501S water treatment aeration fan_rotary blower_Rotary fanDetailed description of

1. Rotary fan (rotary fan,Sliding blade fan）Main purpose and characteristics: (illustrated)

Rotary blowerPurpose:

● Water treatment blast aeration

● Sewage mixing and aeration in hospitals and laboratories

Vacuum paper feeding in the printing industry

Mixing and aeration of electroplating tanks and industrial wastewater

● Gas supply for plastic welding and blowing

● Burner spray, glass industry

Characteristics of rotary blower:

Small size, high air volume, low noise, and low energy consumption (Rotary blowers use the principle of operating compressed air. Although small in size, they have high air volume, energy efficiency, and silent operation that other forms of fans cannot compare to.)

Smooth operation and easy installation (For small models, as long as they are properly placed, the vibration is minimal and there is no need to install anti vibration devices, making installation convenient.)

● Resistance to load changes and stable air flow (for example, if the pressure of the aeration tank in sewage treatment changes, the load changes, but the air flow changes very little with pressure changes)

Equipped with an air chamber for smooth air dispersion (All models come with an air chamber to prevent air pulsation and ensure smooth air dispersion.)

The material is excellent, the structure is clever, and the performance is outstanding (the blower is made of high-quality materials, with exquisite structure, sturdy and durable, excellent performance, and few long-term failures)

Easy maintenance, few malfunctions, long lifespan (low speed, minimal wear, long lifespan)

Disadvantages of rotary blower:

Rotary fans are oil lubricated fans that require careful maintenance during daily use, especially the maintenance of the fan lubrication system. Insufficient oil use of the blower can cause serious damage to the fan.

The rotary blower is an oil lubricated blower, and the discharged air contains a certain amount of oil mist, which increases the technical difficulty of water treatment and generates secondary pollution. Although the blower manufacturer has continuously improved the oil gas separation tank (storage tank) of the rotary blower, the high temperature generated by the compression of the blower inevitably leads to the evaporation of lubricating oil. YH series oil-free and low-noise is recommended for small aeration blowersWater ring fanIt will make your fan room quieter, the air cleaner, and easier to maintain.

2. HC-501S blower, rotary fan, rotary fan, air volume: 1.44-1.32m3/min

The fan air volume Qs refers to the inlet flow rate of a rotary blower in a standard suction state (pressure 101.325kPa, temperature 20 ℃, relative humidity 50%) with air as the medium, and is converted for flow segments in non-standard states.

3. HC-501S blower, rotary fan, rotary fan pressure: 0.1-0.5kfg/cm2

Pressure unit conversion: 9.8kPa=0.1kgf/cm2=1000mmH2O=73.5mmHg=98mbar r=0.0967atm

Detection conditions and methods for noise of rotary fans

1、 Fan installation section

1. The fan needs to have a foundation or be equipped with vibration reducing components

2. The air outlet needs to be connected to the pipeline equipment

3. The fan pressure should be within the specified range (pressure gauge shows 0-0.05MPa)

4. The inner wall of the fan room needs to be equipped with sound-absorbing materials to reduce noise

2、 Testing method

1. Inspection outside the fan room: Testing at a distance of 2-6 meters from the fan room will reduce the fan noise test value to the standard value.

In addition, the size of the fan room and the surrounding environment also have an impact on the noise test values. (First, meet the installation requirements)

2. Open space detection: Within 20 meters of the tested fan, there are no obvious buildings or other obstacles that can produce echoes. The fan is equipped with vibration reduction components and tested under no-load operation (30ml of lubricating oil is poured into the air inlet before the detection, and the running time cannot exceed 5 minutes). The fan noise test value will be reduced to the standard value when tested 1-10 meters away from the fan. The environment also has an impact on the noise test value.

3 Sensory detection: The fan has no abnormal noise, no inorganic collision noise, no abnormal vibration without overpressure, no intake noise, motor operation noise, and ground micro vibration are all normal sounds.
