Shanghai water pump factory outlets | Shanghai Liancheng sewage pumps | sewage pump sewage pump submersible pumps Model category installation steps: 1, after unpacking, checking pumps and accessories die because no complete. Optional pump nameplate parameters adapt job requires. 2, with a hard steel hose or PVC pipes, metal water pipes, water pipes, import and export pipeline, attention caliber match, and interfaces tightening, make sure Gas sealed joints. 3, select the appropriate location to place or fixed pumps. The pump should be put right placement method. 4, depending on the circumstances of pumps, pump reference before such requirements and do before starting the water supply, drain suction pipe air, out of the taps and other preparatory work. 5, on the power, a moment that is able to pump the water. 6, after the use of submersible pumps, if extended period of time, should not be soaked in water, should be placed in the water for several minutes electricity, cleaning mud pump inside and outside, then just rub. Apply rust placed in dry air reserve. Note the use of sewage pump (1) operation before applying megger stator winding insulation resistance to ground, not less than 50 megohms minimum. (2) Check the cables for damage, breakage and so on. If damage must be replaced to avoid leakage; cable cross section should match the current. (3) the voltage exceeds ± 10% of rated voltage shall not start pumps. (4) in order to ensure safety, must be four-core cable ground wire grounded to prevent electric shock. (5) When the pump submerged, vertical lifting should not allow cross-lying land, but can not fall into the sludge. Stop using the pump should be lifted clean, dry place, and pay attention to antifreeze. (6) prohibit the cable re-start line. (7) Check the rotor rotation direction, looking down from should rotate clockwise. (8) outdoor switch or terminals should be rain, moisture-proof measures, when wet hands or barefoot prohibited touch switch to prevent electric shock. (9) Move pump, must be cut off, pump runtime person shall contact with water, to prevent the occurrence of leakage accidents. (10) non-motor phase operation, such as found in a blown fuse, only after continued use should check the reason can not be any bold fuse. (11) when the pump is running, there should be someone administration, if there is an abnormal phenomenon should immediately stop inspection, troubleshooting. (Referring to the situation at the end of the cabinet with automatic protection). (12) pump in the working medium conditions specified normal operation after six months, you should check the oil chamber seal condition, such as an oil chamber of the oil milky or water precipitation, should be replaced 10 to the 20th machinery oil and mechanical seals. For pumps in harsh working conditions, but should always overhaul. (13) The user should select the appropriate flow head according to actual use conditions in order to achieve the best results, the pump nameplate or shown in the specification parameters for optimal use operating point, user-selectable in (0.7 to 1.2) times the optimum flow use, prohibit the use of excess flow easily over current, motor burned.
