5、 lowest the automatic cooling syst- -ling system.3.Rated voltage 380V, rated frequency 50Hz. The motor can run successfully only under the condition the deviations of both rated voltage and frequency are not over 5%.4.The maximum diameter of the solid graingoing through the pump has not to be larger
6、 than 50% of that of the pump outlet. 02SKF NTNoF155CIPX8/CAD/CAMBearing:Imported SKF of NTN bearing, which, with a reasonableconfiguration, can oxtend the duration of the pump.Cooling:The buit-in cooling system can have the pump normally work whether the motor is on or under the liquid surface. A p
7、art of the liquid is extracted to bring out the beat produced by the motor from the pumpcirculation to the cooling barrel and to the pump casing and, when external cooling is required, thecooling sleeve may be separated from the pump casing and in-dividually connected to the cooling system.Motor:o O

27、USE, CHECK AND SERVICE 1 1.Precautions at use It is not proper to use the pump in a medium environment easy to explode and burn and to extract any combustible liquid. It is strictly prohibited to impact or press the cable and use it as a lifting rope, and pull it at will when the pump is running so
28、as not to damage it , which may result in an electric shock, or lowering the cable sealness, or the insulation performance of the wiring box of the motor. When to use the way of fixed automatic couoling installation, lift or lower down the pump with the lifting chains locking the handle and take car
29、e to handle it. The pump has to be vertically lifted when it is placed in water and not horizontally landed, further more, not sunk into sludge. 2 A flow regulating valve must be equipped with the spitting pipeline to avoid overload of the motor due to a too heavy flow. 2.Check before use Carefully
30、check if there is any deformation or damage with the pump and any looseness or fall-off with the fasteners during transport, storage and installation. Check if any damage or fracture with the cable, if the seal 500V 2 120 on its inlet intact and make a proper treatment in time if any possible leakag
31、e or bad seal is found. Measure the dielectric resistanc e between the phases and between the phase and ground with a 500V megohm 2 meter, the value of which has not to be lower than megohm, otherwise a drying treatment must be taken for the stator winding of the motor with a temperature not over 12
32、0 acturer for help. Check if there is oil in the oil chamber and do not stop filling it until it overflows on the filler. Check if the screw cork and sealing pad on the oil chamber are full and if the screw cork presses the sealing pad tightly. or notify the manuf- U W V Check if the impeller rotate
33、s flexibly. Check if the power device safe, reliable or normal and if the grounding wire inside of the cable reliably grounded. Before placing the pump in the pool, check if it is in a correct. Direction of rotation by way of dot moving and cut off the power and change the U,V, W three wires with an
34、y two of which in the electric control cabinet if not correct. 34 WQ SERIES SUBMERSIBLE SEWAGE PUMP 3.Starting Close the flow regulating valve on the spitting pipeline at starting and gradually open it when the pump gets in the full speed running. Note the pump can not run for a long time with the v
35、alve closed. 4.Stopping Lift the pump, clean it and place it in a dry place when intended not to use it up to half a month and lift it out of the water and let the liquid inside o f it drain out to prevent it from being frozen when the temperature is very low. 5.Check Periodically check the dielectr
36、ic resistance between phases and between phase and ground, the value of which should not be lower than 2 megohm, otherwise it has to be removed to 2 2mm overhaul, and, at the same time, check if the grounding is secured and reliable. Replace the seal ring with a new one when the erval of it,
37、mounted on the impeller neck and pump casing,is over 2mm. After half a year running of the pump under the provided working medium condition, check the state of the oil chamber and replace it with N10 mechanical oil if it shows emulsified state. It is possible that the mechanical seal on the pump. Si
38、de is made damaged when the leakage probe gives a warning with the pump running for a short time after the oil replacement and replace it at once. More often check the pump when it is used under a very adverse working condition. After one year work of the pump under the normal working condi tion, a
39、big overhaul must be taken for replacing the worn out parts, checking the fasteners and supple-menting or replacing the grease on the bearing so as to ensure a good lubrication of the pump during its running. To disassemble, do not knock at it at will in order to avoid damaging the seal and do not a
40、llow non-skilled persons to do that in order not cause it leaking or the motor damaged.
