Jiangsu Roots blower, blower prices - Details Chang Sheng Zhangqiu Roots blower: Roots blower - pneumatic conveying system type II: pulse pneumatic conveying and pneumatic conveying pulse features introduced to plug flow (between cutoff) of The method of delivery of materials referred to in the form of pulses of pneumatic conveying. Pulse pneumatic conveying is abroad in the 1960s developed a new technology, our country in the 20th century. First introduced in the 1970s. In recent years, has been used in the chemical industry, machinery, building materials, metallurgy, light industry and other sectors. The working principle (see Figure 2) are: material is transported from the hopper into the tank pressure to send a 2 (the tank pressure of about 60 ~ 220kPa), under compressed air into the conveying pipe 3. Pulsed air flow through an air knife 4 (air knife pressure of about 80 ~ 240kPa) into the pipeline. Thus, the gas knife i.e. the material is divided into discrete solid flow (plug flow) is conveyed. The length of the piston material by air knife pulses to control airflow, air knife intermittently into the conveying pipe through the air blower clover lubricants, cutting material column, making it non-continuous plug flow (ie some material plunger, some gas piston) Clover Roots blower gear, by pushing gas hydrostatic delivery. Air knife is a ventilation valve controlled by a solenoid valve, solenoid valve by the pulse signal generator control, according to the time required to open and close for a pulse aspirated, so the pressure feed tank down the powdery material is cut into the same air cutter the length of the plunger material. Pulse pneumatic conveying system due to high productivity (feed gas ratio of up to 30 to 300 M), transmission distance is long (up to 500m), less air consumption, transmission speed is low (usually only 1 ~ 2m / s), less wear and tear duct, easily broken during transport materials, low energy consumption, etc., so it is a very promising way of pneumatic conveying. Characteristics of Roots blower inside and out thanks to the rotor structure in the form of clover and reasonable housing outlet structure, so the fan vibration, low noise. Impeller and shaft for the overall structure and impeller wear, fan performance enduring, long-term continuous operation.
