9-19 high pressure centrifugal fan
9-19 high pressure centrifugal fan is generally usedforforging furnace and high pressure forced fan, can bewidely used in conveying materials, conveying air andnon-corrosive nature, non-sticky substances and gases. The medium temperature is generally not more than 50℃ with maximum below80℃. The concentration of mediacontaining dust and particles is not more than 150mg/m3.Product type: The factory number is NO3.15, 3.55, 4, 4.5, 5, 5.6, 6.3, 7.1. It can be made into two types: right-handed and left-handed. The impeller rotates clockwise and is called a right-handed fan. Expressed as "right", the impeller rotates counterclockwise, called the left-handed fan, and is represented by "left". The outlet position of the fan is expressed by the air outlet angle of the casing. The 9-19 type fan NO3.15~7.1 is made into various types when it leaves the factory. It can be installed to the required position according to the requirements of the unit, that is, the position of the air outlet is adjusted. The range is 0°~225° or 45°, that is, (0°, 45°, 90°, 135°, 180°, 225°). NO7.1 is made into a direction angle according to user requirements. The transmission mode of the fan is A type (NO3.15~6.3) and D type NO7.1.Structural features: The fan is mainly composed of impeller, casing, air inlet, frame, chassis, bearing box and other belt drives. Impeller: It consists of 10 backward-inclined airfoil blades, curved front plate and flat rear plate. It has dynamic balance correction and aerodynamic performance, so it has the characteristics of balanced operation, small vibration, high efficiency and long service life. Housing: welded with a steel plate into a volute casing. Air inlet: made into a whole (all mold molding), installed on the side of the fan, and the axially parallel wearing surface has a curved shape, which enables the gas to smoothly enter the impeller with less loss. Transmission group: from the main shaft, bearing housing, coupling and so on. The main shaft is made of high-quality steel. The overall structure of the bearing housing is made of rolling bearings and is divided into water-cooling and oil-cooling.
