Water ring vacuum pump excitation control details


I think many friends are very interested in the excitation control of water ring vacuum pump, this is really a key and difficult work, next I will introduce some relevant content, you can read it carefully.
1. Open-loop simulation test for closed loop regulation of potential (or voltage). The simulation mode gives the armature terminal voltage and armature loop current, and sets the output limiting value, excitation current and feedback loop parameters of the potential (voltage) regulator.
2, excitation current (or flux) regulation closed-loop control of the step response to adjust the dynamic characteristics. The dynamic characteristic indexes of k should be measured and adjusted respectively in the full magnetic working area, near the starting point of weak magnetic field and the weak magnetic working area to meet the design requirements.
3. The excitation loop of the water ring vacuum pump is connected to the power supply to check and adjust the preset parameters, including the minimum magnetic flux (excitation current) limit value, the setting value of magnetic loss protection action, the setting value of full magnetic current and the weak magnetic control curve.
Above is the water ring vacuum pump some knowledge, you can refer to. Today's content is introduced here, hope to help you, want to know more knowledge can continue to pay attention to us.

Reasons and Solutions for Fragile Belt of Roots Blower

图片
1. Reasons for easily broken belt of Roots blower: 1. First of all, consider the high speed and high temperature of Roots blower. 2. The distance between the head and motor of Roots blower is too large and the belt is tight. 3. The belt does not match the V groove of the pulley, so it can not withstand the load fracture after wearing. 4. Active pulley and driven pulley are not parallel, resulting in serious friction between belt and groove on one side, and can not bear load fracture after wear. 5. Heavy load, long-term overload operation of belt is easy to break. 6. Roots fan nose and motor pulley are not concentric, different axes. 7. Belt quality problems. 2. Measures to prevent the belt of Roots blower from breaking. 1. Roots blower must start without load before running. After starting, it should be loaded. After running, it can generally avoid triangular belt breaking. 2. The pulley between the motor and the fan should be parallel, which is a key point. If not para
