2、 Working principle of high-pressure fan:
When the impeller rotates, due to the centrifugal force, the wind vane drives the gas to move forward and outward, forming a series of spiral movements. The air between the impeller blades accelerates and rotates in a spiral shape, squeezing the gas outside the pump body into the side groove (sucked in through the suction port 1). When it enters the side channel, the gas is compressed and then returns to accelerate and rotate between the impeller blades again. When air passes through the impeller and side groove along a spiral trajectory, each impeller blade increases the degree of compression and acceleration. As the rotation progresses, the kinetic energy of the gas increases, further increasing 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.
3、 Selection principle of high-pressure blower:
a、 Need to determine what function of the high-pressure blower is used on site, whether it is suction or blowing, and find the corresponding pressure flow curve of the high-pressure blower; If the curve is misread, sometimes the selected product cannot be used.
b、 Based on the calculated pressure and flow rate, find the working curve above the corresponding working point that satisfies both pressure and flow rates on the curve graph; Then select the high-pressure blower model based on the working curve.
As long as it is a different work site, its requirements for pressure and flow rate are different, so in order to have relatively accurate data, relevant calculations need to be carried out. This needs to be done by professional designers or consulted with professional companies.
4、 Precautions for using high-pressure blower:
High pressure blowers require protection in two aspects: pressure and dust.
For pressure, a relief valve is often used, which is an unloading valve. When the operating pressure of the high-pressure blower exceeds the set pressure of the relief valve, the relief valve will automatically open to release the excess pressure and protect the high-pressure blower.
For dust, Gaorui filters are often used. It often uses filter cartridges with different filtration accuracies according to different usage scenarios. Different filter cartridges have different maintenance methods and service lives, which need to be clarified when ordering.
In some special occasions, special protection is also necessary: for example, when using in a sealed environment, attention should be paid to ventilation and heat dissipation; When the ambient temperature (intake temperature is relatively high), it is more important to pay attention to ventilation and heat dissipation, or choose a high-pressure blower that allows for a higher intake temperature,.
5、 Application of high-pressure fan:
