(1) Changing the opening degree of the valve Changing the valve switch on the outlet line of the high pressure blower (whirlpool type pump) is actually changing the characteristic curve of the pipeline. When the valve is closed, the local resistance of the pipeline increases, the pipeline characteristic curve becomes steep, the working point moves from M to M1, and the flow rate decreases from QM to QM1. When the valve is opened, the resistance of the pipeline is reduced, the pipeline characteristic curve becomes flat, the operating point moves to M2, and the flow increases to QM2.
The use of valves to regulate the flow quickly and easily, and the flow can be continuously changed, suitable for chemical continuous production characteristics. So the application is very extensive. The disadvantages are that when the valve is closed, the resistance loss increases and the energy consumption increases. This is not economical.
(2) Changing the rotational speed of the high pressure fan (whirlpool type gas pump) Changing the rotational speed of the high pressure blower (whirlpool type gas pump) essentially changes the characteristic curve of the pump. The high-pressure fan (whirlpool type gas pump) has an initial rotation speed of n and a working point of M. If the rotational speed of the high-pressure fan (whirlpool type pump) is increased to n1, the characteristic curve H-Q of the high-pressure blower moves upward, and the working point is moved by M. To M1, traffic increased from QM to QM1. If the rotational speed of the high-pressure fan (whirlpool air pump) is reduced to n2, the operating point moves to M2 and the flow drops to QM2.
High-pressure fan (vortex pump) flow regulation method Release time:2016-06-12
High-pressure fan (vortex pump) flow adjustment method We often say practice makes perfect. However, when using a high-pressure fan (whirlpool type pump), the technique is also very important. In the following, Liang Shue simply talks about the flow adjustment method of the high-pressure fan (vortex type pump). Through this comparison, I hope to be able to give some advice to friends who want to buy a high-pressure fan (whirlpool air pump)!
