What Is The Working Principle Of A High-pressure Blower?
A high-pressure blower is a blower with a relatively large wind pressure. As a general-purpose machine, it is widely used. Many friends are interested in the principle of a high-pressure blower. Here is a brief introduction for everyone.
To know the principle of a high-pressure blower, you must first understand its structure. Generally, a high-pressure blower consists of six parts: a motor, an air filter, a blower body, an air chamber, a base (also an oil tank), and an oil drip nozzle. Its specific working principle is:
The motor provides power for the high-pressure blower to rotate the impeller in the blower. 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 by the air intake). After 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 side channel narrows at the outlet), the gas is squeezed out of the blades and discharged from the pump body through the outlet silencer. Since other rotational movements will draw in air from outside the machine, when the gas enters the outer air ring, the pressure difference will cause the gas to return to the base of the blades to form a strong airflow. Following this trajectory over and over again, the purpose of pressurization can be achieved.
