Ring type roots air blower as vacuum pumps for oxygen air convey in paper pulp 0.6 - 28 kgf/cm2

Goods Description

When leaf wheel of Ring Blower operate, it will create air flow, which will be enforced by the surrounding air, and eventually the total air body will be pressured and moved to the air outlet of the Ring Blower and then goes out. The Ring Blower features high Reliability. The blower has unique tolerance in high pressure. When circumstance suddenly changes, Ring Blower can still run safely and smoothly. Because of its simple design, it needs almost no maintenance. With fine-cooling outer bearing, the blower also has the following features: (1)High pressure. (2)The bearing operates with low temperature. (3)The lubrication gives extra durability in use. (4)Easy maintenance.

Features

• Low noise and vibration:Dynamic balancing minimizes vibration.
• Dust-proofed shaft seal:Protects bearings from contaminated air stream and possible foreign particle damage.
• High reliability:Directly connected motor shaft-impeller provides reliable, long term performance. No gears, belts, motor brushes or sliding blades to require periodic maintenance.
• Space-efficient design:Unique design results in substantial airflows at moderate pressures in minimum space and weight.
• Versatility:Easily throttled and changd from pressure to suction operation. May be mounted in a variety of fashiond.
• Stable airflow:Centrifugal compressor design delivers smooth, stable airflow with no pulsations.
• High-pressure airflow:Produces continuous high-pressure airflow. The Ring Blower is ideally suited to many industrial application.
• No grease, no pollution:The leafwheel, when in operation,, is isolated from other parts of the machine, no need lubrication, so this means no cause of pollution at all.
• Easy installation:The well-equipped blower can be easily installed at any place, any time, for air-compressing or air-vacuuming；can be set vertically or horizontally.

Model selection

1. The air volume shown in above performance form, it's the suction volume under standard suction condition (Temp. 20 ℃, absolute pressure 1.0332 kg/c㎡, relative humidity 65%).

2. The convert formula between normal (for example: 0 ℃, 1.0332 kg/c㎡, ABS) and standard condition:

Qs=Qn * (yn/ys), y=0.465 * (P-0.378 ᵩ * Ps) / (273+t)

ᵩ=humidity (%) P=Pressure (mmHg)

Qn: air flow under normal condition N m³/min

Qs: air flow under standard condition (indicated in above performance table m³/min)

Y: air ration weight (kg/m³)

Ps: water vapor saturation pressure of the temperature (mmHg)

T: absolute temperature (273+t) ℃

3. Vice versa, an air flow under discharge condition can be converted to an air flow under standard condition:

Qs=Qd * (1.0332+Pd) * (273 +Ts) / (1.032*(273+Td))

Qd: air flow under discharge condition, m³/min

Ts: suction temperature

Td: discharge temperature

Pd: discharge pressure, kgf/㎡

4. Select blower type, diameter, rpm and shaft power based on performance table as required the air flow and discharge pressure.

5. Smaller size for economic view, and larger size for lower noise level & stabler performance for a long view.
