Description

Technical Field

[0001] The utility model relates to the field of high-pressure fans, in particular to a sound insulation control box for high-pressure fans. Background Art

[0002] A high-pressure fan refers to a fan with a wind pressure of 30kPa to 200KPa or a compression ratio of e=1.3 to 3 under design conditions. Currently, the industry generally classifies gas ring vacuum pumps as high-pressure fans. High-pressure fans, also called high-pressure blowers, are different from general centrifugal blowers.

[0003] Its 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 impeller blades accelerates the rotation in a spiral shape and squeezes the gas outside the pump body into the side groove (sucked in from the air intake). When it enters the side channel, the gas is compressed and then returns to the impeller blades to accelerate the rotation again. When the air passes through the impeller and the side groove along a spiral track, each impeller blade increases the degree of compression and acceleration. As the rotation proceeds, the kinetic energy of the gas increases, which further increases the pressure of the gas passing through the side channel. When the air reaches the connection point between the side groove and the discharge flange, the gas is squeezed out of the blades and discharged from the pump body through the outlet muffler.

[0004] The existing high-pressure fan is installed in a box, but due to the operation of the high-pressure fan, it will cause certain noise during operation, causing pollution to the surrounding environment. At the same time, it is impossible to monitor the working status of the high-pressure fan in real time, which has certain limitations. Utility Model Content
