ã€Asia pump network】 LW-type pipe sewage pump with significant energy saving, anti-winding, non-blocking, automatic installation and automatic control and so on. In the delivery of solid particles and long fiber garbage, has a unique effect. Adopting a unique impeller structure and a new mechanical seal, it effectively delivers solids and long fibers. Impeller compared with the traditional impeller, the pump impeller single or dual flow channel form, which 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. LW-type pipe sewage pump characteristics selection and use LW-type pipe sewage pump installation and use: 1. First check whether the external fasteners loose during transport. 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. Inspection and maintenance: 1. Pump before use should check the insulation resistance of motor windings on 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. Common causes of failure 1. No water, was pumping heavy liquid and particle size is too high; liquid flow path blockage; impeller steering error; pumping 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.
