I. Definition of 2 hp ring blower: 2 hp ring blower refers to the fan with wind pressure of 30kPa~200KPa or compression ratio E =1.3~3 under design conditions.
The current industry is generally the gas ring vacuum pump is classified as 2 hp ring blower. 2 hp ring blower is also called high pressure blower, different from the general centrifugal blower.
Two, the working principle of 2 hp ring blower: when the impeller rotates, due to the centrifugal force, the impeller makes the gas move forward and outward, so as to form a series of spiral motion. The air between the impeller blades rotates spirally and squeezes the gas outside the pump body into the side groove (inhaled by the suction port). When it enters the side channel, the gas is compressed, and then returns to the impeller blades to accelerate rotation again. When the air passes through the impeller and side grooves along a spiral track, each impeller blade increases the degree of compression and acceleration. As the rotation progresses, the kinetic energy of the gas increases, making the pressure of the gas passing through the side channel further increase.
When the air reaches the connection point between the side groove and the discharge flange, the gas is extruded from the blade and discharged from the pump body through the outlet muffler.
3. Structure of high voltage fan: motor: wide voltage/dual-frequency motor, IE3 motor, explosion-proof motor and special customized requirements can be provided. Import and export air duct: convenient for customers to connect pipelines, while part of the muffler function impeller: aluminum alloy die casting, light weight, high dynamic balance accuracy, vibration small bearings: NSK/SKF bearing imports, higher reliability and longer service life of chassis, aluminum alloy die casting, casting and machining performance good sealing ring: according to actual use environmental requirements, provide various kinds of sealing ring four fan according to the direction of gas flow classification, the classification of the products can be divided into centrifugal, axial flow fan, oblique flow and cross flow type. When the centrifugal fan works, the power machine (mainly the motor) drives the impeller to rotate in the cochlear housing, and the air is inhaled from the center of the impeller through the suction port. Due to the dynamic action of the blade on the gas, the pressure and speed of the gas can be increased, and under the action of centrifugal force along the blade passage to the housing, discharged from the exhaust port. Because the flow of gas in the impeller is mainly in the radial plane, it is also called runoff fan.
According to the number of built-in impeller classification, according to the number of built-in impeller, can be divided into: single stage fan, double stage fan and three stage fan. At present, the common types of 2 hp ring blowers on the market are single-stage fans and double-stage fans. Single section 2 hp ring blower design only one impeller, small air volume, can meet the installation of food machinery, pharmaceutical machinery, material conveyor, printing machinery, industrial dust equipment, woodworking machinery, plastic machinery, textile machinery and other equipment needs. Double section 2 hp ring blower design has two impellers, faster speed, larger air volume, can meet the needs of large air volume, large pressure, high-speed operation of mechanical equipment. Double section 2 hp ring blower at the same power, the difference between single section, double section and three section 2 hp ring blower: pressure: single section < Double section & lt; Three 2 hp ring blower flow: single section < Double section & lt; Weight and volume of three 2 hp ring blowers: single section < Double section & lt; Three 2 hp ring blower price: single section < Double section & lt; Three-stage 2 hp ring blower
