Main Characteristics

Optimized lobe curve is adopted for reducing blower'sinternal leakage, improving blower's efficiency and reducingrunning temperature.
Double fuel tank design, fully lubricate the driving endbearing, improve the lubrication ability, make the fan moresuitable for high speed operation.
Adopt the deep groove ball bearing with high precision andsmall friction coefficient, low running noise, prolong the servicelife..
Double fuel tank design, fully lubricate the driving endbearing, improve the lubrication ability, make the fan moresuitable for high speed operation.
Blower Working Principle

Roots Blower s a cubage blower and it discharges a fixed amount of air in proortion to its rotation speed. Every rotation. thereis two lobes to finish three times absorbing and discharging ar.Compared with two lobes blower, it is ofless air pulses, smaller loadchange,higher strength.lower noise and yibration.
Two parallel shafts have three lobes each , all the lobes keep small clearance with each other and housing inside . Every lobesrotation . 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 the timing gears, no any touching between lobes , so it can be turned at high speed without anylubrication inside. It has the following characteristics : Simply configuration ; running smoothly ; good performance stabilization . lhas been widely applied in various industries.

Method Of Reading Performance Sheet

1.The inlet airflow in the sheet based on the standard condition.
2.Normally there is ways to show the airflow value :
(1)standard condition airflow-Airflow at 20Celsius degree :absolute pressure is 760mmHg (101.3KPa):comparative humidity is 65%.
(2) Inlet airflow-Airflow upon to the temperature and humidity at inlet.
(3) Base standard condition airflow---Airflow of dry gas at 0 celsius degree , absolute pressure is 760mmHg (101.3KPa)We can convert each other as follows:
If Ol converts to O2O2=O1xP1/P2xT2/T1O1:Airflow (m'/min) based on absolute pressure P2 (mmH,0), absolute temperature T1(k)02: Airflow (m'/min)based on absolute pressure P2 (mmH,0), absolute temperature T2 (k)
3.There are some duplications when you choose the model, if being for the economical point, vou can choose the samllmodel with the same parameter, or you can choose the big one according to the noise and longevity points.The airflow based on the certain pressure can be changed within 5%.

Special Accessory

1.Working principle
This valve is mainly used in the pipeline for blower.compressor and screw type blower. When blower start, the airwill flow through the valve, and the blower will workingwithout load, after a while, the valve will close because thepressure difference in the pipeline and out, so it realize startwithout load for the blower, and can avoid impacting theequipment and motor.
2.Main characteristics
(1) Being mechanical structure and reasonable design, withoutconk out.
(2) There is no need for bypass and electric executive systemBeing low cost.
(3) It substitute for the security valve, and protect startup insevere condition.
(4) Being easy mounting and maintenance
