100 4 Inch Port Dia 3 Lobe Roots Blower High Efficiency Low Energy Consumption
1 Company brief
B-Tohin Machine ( Jiangsu ) Co.,Ltd. takes on keeping improving our forever seeking; satisfy customers our
invariable promise as its tenet and has won high credit from the market. The company successfully got the
cerficate of high-tech enterprise.
2 Main characteristics
(1) Optimized lobe curve is adopted for reducing blower's internal leakage, improving blower's efficiency
and reducing running temperature.
(2) After shaft's diameter enlarged, no deformation and collision will occur under higher load pressure as
the blower's strength is improved.
(3) The synchromesh gear adopts straight tooth structure for smooth operation.
(4) Deep groove ball bearing of high precision and low friction factor is selected for lowering operation
noise. In addition, because of larger size bearing matched for enlarged shaft diameter, the bearing's load
capacity is enhanced and its service life is extended.
(5) Low noise and vibration, compact and economical energy consumption.
3 Blower working principle
Roots blower is a cubage, and it discharges a fixed amount of air in proportion to rotation speed. Two
parallel shafts have three lobes each, all the lobes keep small clearance with each other and housing
inside. Every lobes rotation, a certain air will be absorbed at inlet and transferred from the housing inside
surface to blower's discharge port.
Two shafts will be turned by timing gears, no any touching between lobes, so it can be turned at high speed
without any lubrication inside, It has the following characteristics: simply configuration; running smoothly;
good performance stabilization. It has been widely applied in various industries.
