Pneumatic conveying Roots blower This is a kind of equipment with simple structure and convenient manufacturing, which is suitable for various low-voltage occasions. It keeps the two rotors engaged through the synchronous gear at the end of the rotor shaft of the compressor. Here are the main functions of this device. The characteristics of Roots blower for pneumatic conveying are that when the pressure is adjusted within the allowable range, the flow change is very small, the pressure selection range is wide, and the forced gas transmission is featured. The medium does not contain oil during transportation. The utility model has the advantages of simple structure, convenient maintenance, long service life and small vibration of the whole machine.
The pulsation of air flow velocity and pressure caused by periodic suction, exhaust and instantaneous constant volume compression produces greater aerodynamic noise. In addition, the clearance between the rotors of the pneumatic conveying roots blower and between the rotor and the cylinder leads to gas leakage, which reduces the efficiency. The capacity of the Roots blower for pneumatic conveying is 0.15 to 150 cubic meters per minute, and the speed is 150 to 3000 rpm. The single-stage pressure ratio is usually less than 1.7 and up to 2.1, which can be used in multiple stages. 
During the normal operation of the pneumatic conveying roots blower, check the bearing temperature every 1 to 2 hours. The temperature of the lubricating oil in the fuel tank and the motor should not be higher than the specified value. The pneumatic conveying roots blower is very noisy during operation. In order to reduce the noise, in addition to installing the silencer, some simple methods can also be used to reduce the noise, such as the underground method. The lubricant of the pneumatic conveying roots blower shall be replaced every 3 to 6 months, or the copper wire with the hole diameter less than 50 microns shall be replaced. After the first start, the working time can reach 200 hours, and the oil should be changed. The muffler should also be repaired every six months to replace some or all of the sound absorbing materials. Frequently check the air filter, inlet valve, outlet valve and bypass pipe to ensure they are in good condition.
