Roots blower is a displacement fan, and the air volume transported is proportional to the number of revolutions. Two impellers are used for suction and exhaust for three times every time the three blade roots blower impeller rotates. Compared with the two blade roots blower, the gas pulsation is less, the load changes less, the mechanical strength is high, the noise is low, and the vibration is small.
Two impellers are set on two parallel shafts. There is always a small gap between the impeller and the inner hole surface of the elliptical case and between the impellers. Because the impellers rotate in opposite directions at a constant speed, a certain amount of gas surrounded by the case and the impeller is transported from the suction side to the discharge side. Its characteristics are that when the pressure is adjusted within the allowable range, the flow changes little, the pressure selection range is wide, and it has the characteristics of forced gas transmission. The medium does not contain oil during transportation.
Due to the adoption of a three blade rotor structure and a reasonable structure at the inlet and outlet of the housing, the fan has low vibration and noise. The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan remains unchanged, and it can operate continuously for a long time with a long service life. Roots blower is mainly used for pressure feeding and vacuum. Let's talk about the pressure feeding purpose of the blower: mainly used for pressure feeding and vacuum. The pressure feeding purpose of Roots blower is:
(1) Waste water treatment: industrial waste water, domestic waste water and other environmental protection projects aerate to supply oxygen or use air backwashing filter material of Sanniu fan. Applicable industry: environmental engineering equipment industry
(2) Powder conveying: use the air compressed by Lurgi fan to transport the powder particles to the place of use. The powder particles available for conveying include plastic particles, PU particles, flour, sand filter materials, shells, etc.
(3) Air mixing of electroplating tank: if the liquid medicine of electroplating tank needs to be evenly plated due to the electroplating products, it needs to be stirred by fan air to achieve uniform mixing. Applicable industries: electroplating industry, electroplating machinery and equipment industry, printed circuit board industry, PCB factory.
(4) Oxygen supplement for aquaculture ponds: many aquaculture ponds need air supplement to supply sufficient oxygen for the fish industry, so as not to cause death and loss due to insufficient oxygen. Some transport vehicles transporting fish products also have fans installed on the vehicles to transfer oxygen to fish products through the operation of fans, Fang will not die due to the lack of air supply due to the long distance of transportation. Applicable industries: aquaculture, fishing, shrimp farms.
(5) Air supply for incinerator: the combustion of incinerator needs air supplement to reduce the black smoke generated due to insufficient air during combustion, which can meet the environmental protection standards. Applicable industry: incinerator manufacturing industry.
(6) Drying the conveying track: cooperate with the installation of air knife, use the fan to compress the air and air temperature, dry the moisture of the track, or dry the moisture of the circuit board. Applicable industries: dyeing and finishing machinery industry, PCB factory
(7) Paper conveying: use the power of air to press paper to the place where it is needed.
(8) Air supply for tunnel works: tunnel excavation works require air supply due to the lack of internal air. Fans are used to transport air to the tunnel interior, sometimes with air coolers.
I believe that after reading the above content, you should also have a better understanding of the pressure feeding purpose of Roots blower, and I hope it will be helpful to you.
