Product Description
1. Introduction
This type three lobe Roots blower is a self-developed new product on the basis of absorbing international advanced technology, which has low power consumption, low noise, excellent performance and low maintenance costs properties. Advanced CAD design tools, process technology and sophisticated CNC equipments are used in product development. This product is widely applicable for metallurgy, chemical industry, light industry, building materials, mining, textiles, pneumatic conveying, sewage treatment, ceramics and other industrial sectors.
2. Characteristics
(1) Large flow and pressure range, wide application, high quality, low price.
(2) Special complex linear envelope vane wheel is used in this product, which
has good gear engage, less leakage and pressure pulse, low noise and high efficiency.
(3) Special shape is designed in the rotor, enhancing shaft rigidity and improving
the blower’s boost
(4) Synchronous gears are made of high quality alloy steel by precision
machining, which relieve the mechanical driving noise effectively.
(5) The rotating parts are all balancing tested rigorously and the product has
almost no vibrations.
(6) Reasonable structure is designed to cooling the blower, effectively improving
the gear and bearing life.
(7) The blower has compact & simple structure, easily for maintenance and repair.
3. Working principle
The two rotors rotate in the opposite directions driven by the synchronous gears and there is appropriate clearance between the two impellers and blower cabinet, which forms air intake cavity. With the rotor rotation, the air is transferred from air intake cavity to air discharge cavity without being compressed, and then exhausts which causes blowing.
