Auto stir JYWQ Note the use of sewage pump 

 (1) operation before the application megger to check the stator winding insulation resistance of not less than 50 megohms minimum. 
 (2) Check the cable for damage, broken and so on. Should be replaced if damaged, to avoid leakage; cable section should be matched with the current. 
 (3) voltage exceeding the rated voltage ± 10% shall not start the pump. 
 (4) to ensure the safe, must be four-core cable in the ground wire be grounded to prevent electric shock accidents. 
 (5) pump into the water should be vertical lifting, does not allow cross-lying land, not to fall into the sludge. 
 Stop using the electric pump should be lifted clean, dry place, and pay attention to antifreeze. 
 (6) prohibiting the use of cable as installed from the sling. 
 (7) Check the operation of the direction of the rotor, should be looking down from the clockwise rotation. 
 (8) outdoor switch or terminal should be rain, moisture measures, the prohibition of wet hands or bare feet touch switch, to prevent electric shock. 
 (9) mobile pump, you must cut off the power supply, pump operation shall not in contact with water, to prevent leakage in injury. 
 (10) non-phase motor running, if found blown fuse should be checked before it can continue to use reason, not any bold fuse. 
 (11) pump operation, there should be staff management, if there is an abnormal phenomenon should immediately stop inspection, troubleshooting. (Referring to the end of the case with automatic protection cabinet.) 
 (12) pump working media in the required six months after the normal operation conditions, the seal should check the oil chamber, oil chamber, such as oil or water emulsion was precipitated, should be replaced 
 10 to 20, machine oil, and mechanical seal. For use in harsh working conditions of the pump, but should be kept for inspection. 
 (13) users should use the actual traffic conditions select the appropriate head in order to achieve the best results, as shown on the pump nameplate or instructions for the best use of parameters 
 Operating point, the user can choose to (0.7 ~ 1.2) times the optimal flow of use, prohibited use of super-flow, or the amount of traffic, easy to lift the motor overload is too low
