About BK Three Lobes Roots Blower
BK series roots blower, with the intergral structure of impeller and shaft, has a waide application in environmental protection, electric power, architecture, gas supply and etc.
Main Chrarcteristics:
1,Optimized lobe curve is adopted for reducing blower's internal leakage, improving blower's efficiency and reducing running temperature.
2,Double fuel tank design, fully lubricate the driving end bearing, improve the lubrication ability, make the fan more suitable for high speed operation.
3,Adopt the deep groove ball bearing with high precision and small friction coefficient, low running noise, prolong the service life..
4,Double fuel tank design, fully lubricate the driving end bearing, improve the lubrication ability, make the fan more suitable for high speed operation.
Working Principle
Roots blower is a cubage blower, and it discharges a fixed amount of air in proportion to its rotation speed. Every rotation, there is two lobes to finish three times absorbing and dischargeing air. Compared with two lobes blower, it is of less air pulses, smaller load change, higher strength, lower noise and vibration.
Two paraller shafts have three lobes each, all the lobes keep small clearance with each other and housing inside. Every lobes rotatiomn, a certain air will be absorbed at inlet and transfeered form the housing inside surface to blower's diacharge port.
Two shafts will be turned by the timing gears, no any touching between lobes, so it can be turned at high speed without any lubrication inside. It has the following chaaracteristics: simply configuration; running smoothly;good performance stabilization. It has been widely applied in various industries.
BY TYPE PERFORMANCE PARAMETERS SHEET
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 Ql converts to Q2
Q2=Q1×P1/P2×T2/T1
Q1:Airflow (m'/min)based on absolute pressure P2(mmH,0),absolute temperature Tl(k)
Q2:Airflow(m'/min)based on absolute pressure P2(mmH0),absolute temperature T2 (k)
3.There are some duplications when you choose the model,if being for the economical point,you 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%
