Silent oil-free treatment aeration fan

Low noise, oil-free, environmentally friendly, aeration blower-Water ring blowerDetailed description of

1、Water ring fan(Environmental protection fan, aeration blower) Main uses:

1、 Water treatment blast aeration 2、 Sewage mixing and aeration in hospitals and laboratories 3、 Vacuum paper feeding in the printing industry 4、 Mixing and aeration of electroplating tanks and industrial wastewater 5、 Gas supply for plastic welding and blowing 6、 Burner spray, glass industry 7、 Aquaculture 8、 Other equipment that requires a gas source

2TheYH-SThe significant features of the water ring fan are:

1Isothermal compression and transportation are mandatory;

2The flow rate of the whole machine does not change significantly with the increase in pressure. (Pressure range:0.1kg/cm2—0.6kg/cm2）；

3The fan does not require oil lubrication, so the air conveyed is clean air. (Water as working fluid, sealing fluid);

4The whole machine has low noise and no vibration, with a long lifespan. (The whole machine has no mechanical wear and tear);

5The main shaft of the fan adopts oil immersed packing seal, which is easy and convenient to maintain;

YHComparison between water ring fan and other sewage treatment aeration blowers

Rotary blowerOil lubricated blower consumes a large amount of fuel and produces oil mist at the exhaust port, resulting in secondary pollution. Lack of oil will increase wear and damage to the blower. As the wear of fan blades increases over long-term use, the noise of the fan will also increase.

Roots blower: gear transmission, oil lubricated gears. The leakage of the gear oil tank can also cause oil pollution.

Water ring blower: No mechanical wear, water is the working fluid, sealing fluid, and cooling fluid, no mechanical wear or noise, no oil pollution, can provide clean air source, no water shortage or wind, will not damage the blower, and there is no significant change in noise after long-term use.

4. YH-S water ring fan pressure

Pressure unit conversion: 9.8kPa=0.1kgf/cm2=1000mmH2Oh = 73.5 mmHg = 98 mbar = 0.0967 ATM

5. YH-S water ring fan noise curve

The low noise of a water ring fan at the same air volume and pressure is incomparable to other fans.

Detection conditions and methods for fan noise

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: The noise test value of the fan will be reduced to the standard value when tested 2-6 meters away from the fan room.

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. 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.

6. YH-S blower speed

Tip: Under the same air volume and pressure, choosing a low-speed fan has lower noise and longer lifespan.

7. YH water ring blower is particularly suitable for environments

Places with high noise requirements.

2. Places with high requirements for gas sources for water quality treatment.

3. Aeration of environmental sewage treatment equipment in office areas, residential areas, hospitals, etc.

8. YH blower usage conditions

1. The water used by the fan is softened tap water or other softened water, with a water pressure of ≥ 0.01Mpa.

2. Install solenoid valve and water valve at the inlet (already assembled at the factory). The water valve controls the flow rate, and the solenoid valve automatically cuts off the water source when the machine is stopped.

3. The air outlet needs to be equipped with a check valve to prevent water from returning and wetting the muffler during shutdown, thereby reducing the noise reduction effect.

4. If the shutdown time is long, the water in the fan should be drained completely, and the belt pulley should be rotated before starting up.

5. To save water sources for work, it can be configuredGas water separation deviceMake the working fluid circulate.
