QDN / QN stainless steel submersible pump installation instructions and operation method QDN / QN stainless steel submersible pump installation and operation method of use: 1, QDN single phase submersible pump power connector single phase: single phase water pump with grounding plug power cord. Three-phase: ground must be connected with the power grid. 2, overload protection Single-phase pump equipped with a built-automatic thermal overload overload protection device, so other protection devices are no longer needed. 3, three-phase pump rotation direction Test pump motor shaft rotation direction will affect the head and water transmission. The correct direction of rotation from the pump inlet is clockwise. 4, when using the extension cable, be sure to avoid voltage drop and keep the connector dry 5, the outdoor switch or connector should have a rain cover and moisture-proof measures. Do not touch wet switches or touch switches with wet hands. 6, the wiring should be implemented by a qualified electrician, and should comply with the relevant safety standards. QDN / QN stainless steel submersible pump start 1. Before starting, check the pump installation and power connection is correct. 2. The float switch connects directly to the pump to control the start and stop of the pump. Check if the float switch is free from interference with other objects. 3. Small Submersible Pumps For pumps without a float switch structure, the pump is started when the pump is completely immersed in water. The motor will be out of service if the motor is not completely immersed in water or if it is operated in a water temperature exceeding 40 ° C for an extended period of time. When the motor coil temperature is too cold, the thermal protection device automatically turn. 4. Small stainless steel submersible pumps start the pump, let it rotate a few seconds, check its start, run and direction of rotation (for three-phase pump, found the wrong direction of rotation, the two phases should be rotated, and then start), if found No or very little outflow of water, indicating the direction of pump failure, you should turn the phase. QDN / QN stainless steel submersible pump operation 1, when the pump is running, you must pay attention to the water level (especially in the small capacity operation), once the water level is not enough, you must disable the pump operation. If the submersible pump runs long hours without water, the motor or coil will burn out. 2, the actual length 髙 degrees (from the water to the destination) should not be less than 80% of the required lifting height (see the nameplate). 3, QDN stainless steel submersible pump voltage fluctuation range should be within 10% of the rated voltage, otherwise it will reduce the motor life, and even damage the motor. 4, QDN submersible pump When the pump is running, if found abnormal phenomenon, such as different sound, less water or no water, should immediately turn off the power to stop the pump. Do not touch the pump when the pump is energized or wet. (Editor: Xiaoxia QQ:) Recommended reading: 2017 exhibition information
