Servo motor brand submersible sewage pump sewage pump installation methods which classification

Servo motor Brand | submersible sewage pump installation methods | sewage pumps classified pulsating magnetic field which in the absence of AC servo motor control voltage, the stator field windings only produce rotor stationary. When a control voltage, a rotating magnetic field is generated in the stator, the rotor rotating magnetic field along the direction of rotation, at a constant load, the motor speed control with the magnitude of the voltage change, when the control voltage of opposite phase servo motor will be reversed. AC servo motor works with split-phase single-phase induction motor, although similar, but the former than the latter rotor resistance is much greater, so the servo motor compared to single asynchronous motor, has three salient features: 1, starting torque Great As the rotor resistance, its torque curve characteristic curve shown in Figure 3, with the ordinary asynchronous motor torque curve compared to Figures 1 and 2, there is a clear distinction. It allows critical slip S0> 1, so that not only the torque characteristics (mechanical properties) closer to linear, and has a larger starting torque. Therefore, there is a control voltage when the stator, the rotor rotation immediately, namely with a starting fast, high sensitivity. 2, run a wider range 3, no rotation phenomenon normal operation of the servo motor, as long as the loss of control voltage, the motor stops immediately. When the servo motor is out of control voltage, it is a single-phase running, the rotor resistance, both the torque characteristics of the rotating magnetic field of the stator and the rotor role in two opposite directions of rotation of the generated (T1-S1, T2-S2 curve ) and synthetic torque characteristic (T-S curve) WQ submersible sewage lift pump is the introduction of foreign advanced technology, based on the combination of domestic water pump features the successful development of the new generation of pumps, energy-saving effect is remarkable, anti-winding, non-blocking, automatic installation and automatic control and so on. In the carriage of solid particles and long fibers litter, it has a unique effect. Submersible sewage pump uses a unique structure and a new mechanical seal, can effectively contain solids conveying and long fibers. Compared with the conventional impeller impeller, submersible sewage pump impeller flow channel or double channel single form, which resembles a cross section of the same size elbow, the flow of a very good, with reasonable cochlear room, making the pump have high efficiency impeller static and dynamic balance test, the pump no vibration during operation. WQ submersible sewage pump Features 1, submersible sewage pump Distinctive single or two-piece impeller structure, greatly improving the dirt capacity, which can handle 5 times the pump diameter fiber material with a diameter of about 50% of the pump diameter solid particles. 2, submersible sewage pump mechanical seal with anticorrosive hard tungsten titanium material to enable safe more than 8000 hours of continuous operation. 3, the overall structure is compact submersible sewage pumps, small size, low noise, energy-saving effect is remarkable, easy maintenance, no need to build pumping stations, dive into the water to work, greatly reducing the project cost. 4, submersible sewage pump seal oil chamber with high precision interference leakage detection sensors embedded in the stator windings of the thermal components, automatic protection of pump motor. 5, submersible sewage pumps can be equipped with automatic control cabinet according to user needs, to pump leak, leakage, overload and overtemperature automatic protection, improved product safety and reliability. 6, submersible sewage pump float switch may vary according to the required level, automatic control of pump start and stop, without special care, extremely easy to use.
