1, QSP fountain pump preparation
1) The use of the environment must comply with the conditions in this manual, should not be discharged mud, ammonia, lime and other water containing solid particles of high or corrosive water quality.
2) Must be properly selected within the recommended head range.
3) Check whether the shaft rotation is flexible, there should be no dead point.
4) Open the exhaust and water plug, the motor cavity filled with water. Attention to prevent false full, good plug, there should be no leakage.
5) with a 500 volt megger measuring motor must not be less than 50MΩ.
6) Install the protection switch, instantaneous departure motor (not more than 1 second), see whether the motor and the signs are the same; if the contrary, the exchange of any two power connector can be, try to turn, you must pour water from the pump outlet, When the water flow from the water section before the start.
7) QS submersible pump with short cable factory, the pump cable connector should be used with ordinary tape, sub-sensitive adhesive tape, plastic insulating plastic bandaging to ensure that the water can not be immersed in the connector. (See the attached cable connector method)
8) In order to ensure safety, the pump should be installed before the use of reliable grounding cable.
9) Preparation of sling, sleepers or steel pipe two, tie the cable with a soft wire or thin rope.
2, QSP fountain pump installation
1) pump installed in the Hetang, the need to use bamboo basket bar in the bottom of the pump, with a tripod or near the boat, near the bridge, list terminal hanging. Surrounding weeds must be removed, must not fall into the mud, resulting in high temperature rise and burn the motor.
2) When installation in the well, the cable should be tied with rope or soft wire rope in each section of the water pipe. Under the pump found stuck, can not be forced under the pump, to avoid the pump and the wall phenomenon. Water supply pipe pad to pad well, bolts tighten evenly to avoid leakage.
3) electric pump diving depth should not be too deep to move below the water level of 0.5 to 5 meters is appropriate.
4) The pump must be installed separately switch and start the protector, not with other electrical devices share, and must match the motor power, protection device rated current rotation position can not be arbitrarily changed to prevent loss of protection. If it is not equipped with the use of start-up protection and damage to the pump, the factory will not be responsible.
3, QSP fountain pump use
1) 500 volt megger to measure the insulation resistance of the motor winding to the ground should not be less than 5 megohm.
2) After the start of the pump, observe whether the current and voltage of the meter accord with the rated range, whether the running sound is abnormal or not and the vibration happens. If not normal should be resolved in time.
3) pump operation, to always observe the voltage, current, flow, head, if one of the following conditions should be immediately stopped running.
A. The rated current exceeds the rated value.
B. Rated head, the flow is larger than the normal decline.
C. Insulation resistance less than 0.5 megohm.
D. Pump intermittent water.
E. The electric pump has sudden sound or large vibration.
F. The protection switch is tripped frequently.
4) Shut down the power, and then start, to wait 5 minutes or longer to prevent the motor temperature is too high.
