Difference between submersible slurry pump and submerged slurry pump
1. The submersible slurry pump works by immersing the slurry pump and motor directly into the liquid without additional fixed support, while the submerged slurry pump generally needs to be fixed, and the motor is above the liquid level when the submerged slurry pump is running.
2. The submersible slurry pump Zui has a large working depth. At present, the design depth is 25m, the standard Zui depth of underwater slurry pump is 1.8m, and the design depth of our company can reach 10m.
3. The stability of submersible slurry pump is higher than that of long shaft submerged slurry pump;
4. The submersible slurry pump is more convenient to use, as long as it is placed under the liquid, and there is no need to make a floating frame or support.
Usage and precautions of submersible slurry pump
1. Carefully check whether the cable is damaged, whether the fasteners are loose or fall off, and whether the pump is deformed or damaged during transportation, storage and installation.
2. The megger shall measure the insulation resistance between the same and relative ground of the electric pump motor, and its value shall not be less than 2 megohm. Otherwise, the motor stator winding shall be dried, and the drying temperature shall not exceed 120 ℃.
3. The rotation direction after connection is counterclockwise from the water inlet. If the electric pump is reversed, just adjust the wiring position of any two wires in the cable.
4. The casing ground wire must be properly connected in strict accordance with relevant regulations. In order to ensure life safety during use, it is strictly prohibited to install personnel nearby to enter the water when the electric pump is running.
5. Under no special circumstances, it must be equipped with full-automatic water pump control. Do not directly connect to the power grid or use the knife switch to connect the power supply to ensure the normal operation of the electric pump.
6. Operate the electric pump under low lift for a long time (generally, the lift shall not be less than 60% of the rated lift), Zui so that it can be controlled within the recommended lift range to prevent the electric pump from burning out the motor due to overload.
7. The pump of the circulating cooling device shall not be exposed to the water for a long time to prevent overheating and damage of the electric pump.
8. Frequency conversion speed regulation device is selected, which has a wider range of working conditions.
