If you want to better apply a product, you need to have a deeper understanding of it. The same is true of liquid ring vacuum pump. The excitation control of liquid ring vacuum pump is introduced to everyone. Let’s have a careful understanding of it. It will be helpful to understand and apply the product.
1. Make full use of the excitation circuit of liquid ring vacuum pump to check and adjust the basic parameters, including the limit value of magnetic flux (excitation current), the fixed value of magnetic protection loss, the fixed value of total magnetic current and the flux weakening control curve.
2. Open loop simulation test of potential (or voltage) Regulation closed loop. The simulation mode provides the armature terminal voltage and armature circuit current, adjusts the potential (voltage) regulator output limit value, excitation current and basic parameters of feedback circuit.
3. The excitation current (or flux) regulates the step response of the closed-loop control. The measurement and adjustment of K dynamic characteristics should be carried out in full magnetic working area, near the starting point of weak magnetic field and weak magnetic working area respectively, and the dynamic characteristic index of K should meet the design requirements.
Liquid ring vacuum pump is widely used at present. The excitation control of this kind of equipment is expected to be helpful to everyone in the future application.
