Precautions should be carefully checked before editing (1) Start pump in the transport, storage, installation process without deformation or damage 80WQ50-35-11 submersible pumps, fasteners loose or fall off. WQ submersible sewage pump innovative production is completed (2) Check the cables for damage, breakage and other phenomena, if damaged, should be replaced to avoid leakage. (3) Check the power supply device is safe and reliable, and the nameplate rated voltage must match. (4) Check the motor stator windings cold megger insulation resistance value shall not be less than 50M Tong ￡ (5) non-pump cable from the sling as the installation and use, to avoid danger. (6) from the direction of rotation of the pump intake look for counterclockwise rotation, if the pump is reversed, just swap any two cables at the terminal position, the pump can forward. (7) vertical submersible pumps should be allowed horizontally, not fall into the sludge, when the pump moves must be cut off. (8) multiple use pump must run into the water for several minutes, leaving the sediment to prevent the pump, ensure pump clean. (9) Long-term pump when not in use, should be removed from the water pump to reduce the chance of stator winding is damp, and increase pump life. (10) Under normal operating conditions, the pump sewage pump after a year, should be carried out maintenance, replacement of worn consumables 80WQ50-50-15 submersible sewage pump, check the tightening state, supplement or replace the bearing lubrication Grease and oil chamber mechanical oil pump ensure good functioning. Two, WQ submersible sewage pump nameplate represent what? ① model and name submersible sewage pumps, traffic regulations, the provisions of head and pump discharge diameter; the number of phases of the motor, rated voltage, rated frequency, rated power, rated current, synchronous speed and quality. This section indicates that this is a submersible sewage pump and its model; traffic regulations and the provisions of the output of the pump head and this pump discharge outlet diameter sizes; allows the use of voltage: 380V rated voltage three-phase or single-phase rated voltage of 220V, use a voltage range allows for fluctuations + 5% to a 10%; rated quite rate: 50Hz or 60Hz; sewage submersible pumps rated power: Effective mechanical power pump on the motor shaft. Submersible sewage pumps running at rated frequency, rated voltage and conditions of use prescribed 80WQ40-40-11 submersible sewage pumps, its performance should be consistent with product standards. ② submersible sewage pump motor thermal fractionation (original insulation class) or temperature limits. Said this submersible sewage pump is running, the motor stator winding temperature rise limits allowed. Stator winding temperature rise does not exceed this limit, submersible sewage pumps long run. 80WQ50-35-11 submersible pumps, submersible sewage pumps, submersible pumps supplied by Anguo Shi Yuan Pumps Limited. Anguo Shi Yuan Pump Co., Ltd. (www.shiyuanbeng.com) strong, credible, in Baoding centrifugal pumps and other industry has accumulated a large number of loyal customers.
