Recently, there are often customers who need industrial vacuum cleaners for inquiries, but come to consult our high-pressure fans. Today, I will analyze the difference between high-pressure fans and industrial vacuum cleaners.
1. High-pressure fan refers to a fan with a wind pressure of 30kPa~200KPa or a compression ratio e=1.3~3 under the design conditions. In the current industry, gas ring vacuum pumps are generally classified as high-pressure fans, which are the main accessories of many large-scale industrial equipment and the main accessories of industrial vacuum cleaners. Generally, it is small in size, with no other moving parts except the impeller, and the impeller is directly connected to the motor, without gears or driving belts. It has high reliability and is almost maintenance-free for life.
Working principle: When the impeller rotates, due to the centrifugal force, the wind vane causes the gas to move forward and outward, thus forming a series of spiral movements. The air between the blades of the impeller rotates in a spiral shape and squeezes the gas outside the pump body (inhaled by the suction port) into the side groove. When it enters the side channel, the gas is compressed, and then returns to the blades of the impeller again. Speed up the rotation. When 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, so that the pressure of the gas passing along the side channel further increases. When the air reaches the connection point between the side groove and the discharge flange, the gas is squeezed out of the blade and discharged from the pump body through the outlet muffler.
High-pressure fans are suitable for industries: printing machinery, burners, film blowing machines, plastic extruders, fruit making machinery, dust collectors, environmental machinery, woodworking machinery, hot air generators, powder and granular conveyors, kitchen machinery , Dryer, incinerator, constant temperature box, mechanical cooling, general suction and air supply.
2. Industrial vacuum cleaner is a kind of supporting or cleaning equipment commonly used in industry. It can be used for waste collection in industrial production process, air filtration and purification, and environmental cleaning. At the same time, it can be used in conjunction with industrial production equipment to absorb dust and debris generated during production to ensure a clean working environment and the health of employees. For example, industrial vacuum cleaners are widely used in the textile and chemical industries to reduce the hazards of some occupational diseases; they can absorb metal debris generated by machining and prevent damage to machinery and equipment. Moreover, the main component of industrial vacuum cleaners and high negative pressure vacuum cleaners is the high-pressure blower, which achieves the function of dust collection and collection in the form of suction pressure.
