Roots fan is an important part of pneumatic conveying equipment. The high reliability of Roots fan determines the reliability of the system. Roots fans are divided into horizontal and vertical. Horizontal Roots fan, which consists of two involute waist rotors (hollow or solid), oblong casing, and two parallel shafts. The casing can be divided into three types with water cooling, air cooling and no cooling device. The transmission mechanism is provided with two gears of exactly the same type and size and meshing with each other at the same ends of the two shafts. The driving shaft is directly connected to the motor, and the driven shaft is caused to rotate in the opposite direction by the gears. Each rotation of the rotor can expel air with twice the shadow volume. Therefore, every time the active shaft rotates, it expels 4 times the shadow volume.
The reasonable arrangement of the inlet and outlet of the roots fan should be: upper air inlet and lower air exhaust (for horizontal), so that high-pressure gas can be used to offset the gravity of some rotors and shafts, reduce bearing pressure and reduce wear. Because it adopts the form of continuous conveyance and coupled with the use of roots fans for conveying power gas sources, power gas sources generally do not need to set up a purification system, and only have certain requirements for gas volume and pressure. Independent gas sources or commonly used in engineering can be used. Air source for air compressor station. Therefore, in the pneumatic conveying system equipment, it is better to reduce the number of elbows of the fan duct as much as possible. This can not only achieve better transmission speed in the entire system, but also save equipment costs. At present, the main industries for pneumatic equipment are thermal power, metallurgy, building materials, water conservancy and hydropower, etc. It not only provides convenient machinery and equipment for the normal operation of these industries, but also makes important contributions to the green and low-carbon development of these industries. contribution.
