Use the float switch to control the coil of the AC contactor, and the AC contactor can control the submersible pump to work. When the water level is too low, the float switch turns on the contact after the float drops, and the control voltage is determined by the working voltage of the selected AC contactor coil to turn on 220 V. In this way, when the water level is low and the floating ball drops to a certain height, the contact is turned on to start the water pump, and when the water level rises, the floating ball contact is disconnected from the AC contactor, and the pump is automatically stopped. The manual button is connected in the control loop of the coil.
Extended data:
The magnetic suspension submersible pump has achieved a major breakthrough in the field of submersible pumps in the world, and effectively solved various disadvantages of traditional submersible pumps, such as low conversion efficiency, large power consumption, limited lift, fragile bearings and frequent maintenance. Widely used in water supply and drainage of industrial and mining enterprises, farmland irrigation and water supply in plateau and mountainous areas.
Magnetic suspension submersible pump has changed the manufacturing process of submersible pump with its unique patented technology, and the conversion efficiency has reached a shocking new level, creating huge energy-saving and consumption-reducing benefits.
The magnetic suspension submersible pump has solved the axial force problem that restricts the development of submersible pump field in the world, and the head of submersible pump has been improved in a breakthrough way, filling the market gap of ultra-high head (single head is designed to be kilometers) and ultra-large flow (high load) submersible pump; The lift and flow curves tend to be flat. Its conversion efficiency and maximum lift of single machine are in the leading position in the world.
Magnetic levitation submersible pump is a new generation of submersible pump, which realizes vertical shaft magnetic levitation (maintaining high efficiency under different working conditions), does not wear, prolongs the service time and maintenance period by several times, saves frequent regular maintenance work, can run for tens of thousands of hours continuously, and saves maintenance and maintenance costs.
The magnetic suspension submersible pump has passed the National Laboratory and Shandong Pump Product Quality Testing Center. The test data prove that the conversion efficiency of magnetic suspension submersible pump is higher than that of traditional submersible pump. Combined with the experimental data and field comparison, the user's use situation further proves its characteristics of high efficiency, energy saving, world-leading conversion efficiency, world-leading single-machine lift, high load, large flow, maintenance-free and long service life.
Matters needing attention
1. If the water pump has any minor faults, remember not to let it work. If the packing of the pump shaft is worn, it should be added in time. If the pump is used continuously, it will leak. The direct impact of this is that the energy consumption of the motor will increase and the impeller will be damaged.
2. If the pump vibrates strongly during use, it must be stopped to check the reason, otherwise it will also cause damage to the pump.
3. When the bottom valve of the water pump leaks, some people will fill the inlet pipe of the water pump with dry soil and flush the bottom valve with water, which is really undesirable. Because when dry soil is put into the water inlet pipe, it will enter the pump when the pump starts to work, damaging the impeller and bearing of the pump, thus shortening the service life of the pump. When the bottom valve leaks, it must be repaired. If it is serious, it needs to be replaced with a new one.
4. Pay attention to the maintenance of the water pump after use. For example, if the water pump is used up, clean the water in the pump. It is best to unload the water pipe and then rinse it with clear water.
5. Remove the adhesive tape from the water pump, then rinse it with water and dry it in the sun. Don't put the tape in a dark and damp place. The adhesive tape of the water pump must not be stained with oil, and it must not be coated with sticky things.
6, carefully check whether there is any crack on the impeller, impeller fixed on the bearing is loose, if there are cracks and loose phenomenon, should be repaired in time, if there is dirt on the pump impeller, should be cleaned up.
