Non-clogged sewage pump uses a unique impeller structure and a new mechanical seal, can effectively transport solids and long fibers. Impeller compared with the traditional impeller, the pump impeller single or dual flow channel form, it is similar to a section of the same size elbow, has a very good overcurrent, with a reasonable volute, making the pump has the efficiency High, impeller static and dynamic balance test, the pump in the operation without vibration, low noise. 　　 Non-blocking pipe sewage pump Features: 　　 1, pump and motor direct coaxial, is a mechatronic product , compact structure, stable performance. 　　 2, the large runner anti-clogging hydraulic components designed to greatly improve the dirt through the ability to effectively pass the pump diameter of 5 times the fiber material and the diameter of the pump diameter of about 50% of the solid particles. 　　 3, reasonable design, matching motor reasonable, high efficiency, low noise, energy-saving effect is remarkable. 　　 4, mechanical seal with hard wear-resistant tungsten carbide, durable, wear-resistant and other characteristics, can make the pump safe and continuous operation of more than 8000 hours. 　　 5, the pump for the vertical structure, import and export center line in the same horizontal line, and the same import and export of flange specifications, installation and removal is very convenient. 　　 6, small footprint, no need to build the engine room, can save a lot of capital costs; in the motor blades with protective cover, the machine can be placed outdoors. 　　 Non-clogged pipe sewage pump installation and use: 　　 1. First check whether the external fasteners are loose during transportation. 　　 2. Check whether the power supply voltage meets the motor nameplate requirements. 　　 3. Turn on the power try to see if the impeller according to the instructions on the pump turn direction, such as the direction of reversal, the cable can be adjusted any two-phase line, the test can not be too long time to avoid burning the seal . 　　 4. Install the pump and turn it on. It is best to install the pump foot screws. 　　 GW non-clogged pipe sewage pump inspection and maintenance: 　　 1. Pump before use should check the motor winding insulation resistance of the case, such as less than 0.5 megohms, just the stator must be dried until the insulation resistance increased before use. 　　 2. The impeller at the pump inlet and seal the gap between the seals should be replaced if more than 2mm wear seal. 　　 3. When the pump seal leakage occurs, the seal should be promptly replaced, the first static seal replacement package real, and then sealed in the shaft seal can be. 　　 4. Replacement of the impeller, pull the application of tension, can not be hit with a hammer, so as to avoid damage to the axis. 　　 No plugged pipe sewage pump common cause of the malfunction: 　　 1 no water, was pumping heavy liquid and particle size is too high; liquid flow blockage; impeller steering error; bar pumping impeller card; pipe outlet height exceeds the rated head height. 　　 2. insufficient flow, low head. Low voltage, impeller steering error or wear seal wear; heavy liquid particles too high. 　　 Insulation resistance is low, the surrounding environment is wet, serious mechanical seal leakage.
