The reason why the submersible slurry pump becomes sluggish:
1. If it is a water circulation submersible slurry pump, it is necessary to check whether there is dehydration work;
2. If there is no problem in the pipeline, the blade in the pump body of the submersible slurry pump is excessively worn;
3. If it is a rotary submerged slurry pump, check whether there is oil in the pump body;
4. It depends on the type and model of submersible slurry pump.
No air leakage is allowed in the suction pipeline system of the submersible slurry pump, and the partition grid of the pump sump shall meet the particle requirements that the pump can pass, so as to prevent large particles or long fiber materials from entering the pump and causing plug.
It is necessary to replace the easily damaged parts in a timely manner, maintain and assemble them correctly, and ensure the clearance is reasonable without tight color friction.
The bearing water pressure and water volume shall meet the requirements, and the tightness of packing shall be adjusted (or replaced) at any time, so as not to cause slurry leakage of shaft seal. And replace the shaft sleeve in time.
When replacing the bearing, make sure that there is no dust in the bearing assembly and the lubricating oil is clean. When the pump is running, the bearing temperature should not exceed 60-650c, and the maximum temperature should not exceed 750C
The coaxiality of the motor and the submersible slag pump shall be ensured. The elastic pad in the coupling shall be complete and correct. It shall be replaced in time after damage.
Ensure that the pump components and pipeline system are installed correctly, firmly and reliably.
