　　B-Tohin has established its professional center covered an area of 400 square meters for inspecting the blowers’ comprehensive properties. And it also introduced the advanced CRAS signal collecting and monitoring system, that is used to collect and send signals such as air volume, blowing pressure, noise, vibration, rotary speed, temperature, electric current and electric voltage etc. to computer for realizing computers’ on-line monitoring, analyzing, record storing and so on. The system ranks front in the same sector.

Abiding by the Performance Test Requirements of Roots Blower, the data listed below are tested and collected mainly. 1、Discharge pressure (0.01MPa, gas pressure): one test point 2、Temperature (0-200℃): temperature at blower inlet, at bearing and of lubrication oil, in total three test points. 3、Vibration: Test vibration velocity and amplitude value of blower in three directions, horizontal, vertical and axial 4、Noise: value measured at four points 1m away from the blower (Weighted Sound Level A) 5、Air capacity: blower air flowrate, with three levels (0-200m–3,0-40m–3,0-7m–3) 6、Electric current: limited by test technology, input and edited after collection by manual 7、Rotary speed: rated speed of 1500 rpm (largest speed of 3600 rpm)
