Low Noise Compact Structure Sl4005 Air Root Blower Three Lobe Double Oil Tank

Low Noise Compact Structure Three-Lobe Double Oil Tank Roots Air Blower

Product Description

1)The Roots blower is a volumetric fan.

2)The air flow is proportional to the speed. The three-lobe impeller rotates each time,and two impellers breathe and exhaust for three times

Compared with the two-lobe type, the gas pulsation is less,the load changes is smaller, the mechanical strength is stronger, the noise is low, and the vibration is small

3) There are 2pcs three-lobe impellers on the two parallel shafts. The slight gap is between the impellers and the inner surface of the elliptical tank and each impeller.

The impeller rotates at a constant speed in the opposite direction. A certain amount of gas surrounded by the tank and the impellers is transported from suction side to exhaust side

4) Each impeller and synchronizing gear always keep the correct phase position, mutual contact does not be happened , so it can be speeded up without internal lubrication, it is simple , stable operation and performance, it adapts to various purposes and uses in a wide range of fields.

Three lobe impellers working principle

Main structure

Main features:

• Driven by helical synchronous gears: Balanced transmission, low noise
• Adopting the advanced impeller curve in the world: increasing the Volume ratio, high efficiency
• All bearings are imported from NSK or SKF bearing, it has good loading performance and long lifetime.
• The oil seal is used CR seal imported from USA.
• Cooling way is air-cooled and water-cooled
• The impeller uses the impeller & shaft integrated structure. It avoids the defects of the impeller shaft split structure.
• Compact structure, the same inlet and outlet impeller structure, flexible installation
• There are various installation ways. The air blower can be installed into horizontal air inlet and vertical air inlet using the same bottom
• It can also change the position of the drive shaft, right or left shaft drive, upper shaft or lower shaft drive
• Double oil tank structure, splash lubrication is used on the gear end and the drive end, which improves the better heat dissipation, and also improves the better lubrication effect of the bearing and gear 

Roots air blower installations reference

Impeller CNC machining center

The impeller is the impeller & shaft integrated shaped of QT500-7. It is integrally processed by machining center to avoid the shortcomings caused by the separation of the impeller and shaft (deformation, thermal expansion, misalignment, wear, etc.)

Roots Blower Performance Test Center

Our company uses the microcomputer roots blower test system which is jointly developed by our well-known test development and research institutions in china under the technical guidance of Japanese and American companies.

This test system introduces advanced CRAS signal acquisition and monitoring system

According to the national industry standard <<JB/T8941.2-1999 general purpose Roots air blower performance test method>>, it is equipped with various signal sensors and display instruments that meet the requirements of test accuracy, high reliability and easy observation.

It collects the air flow, wind pressure, noise, vibration, speed, temperature, current, voltage and other signals into the computer. It can realize online monitoring, analysis, record storage by computer, and it is the leading level among domestic counterparts
