Appropriate loose packing can be selected to clear the blockage of sealed pipe. Must be replaced with new packing. Before installing the screw pump, first soak the oil, then install it circle by circle, and stagger the cuts to reduce oil leakage. When the last ring of packing is loaded, it shall be fixed and its tightness shall be adjusted during operation.

After checking one by one, the following measures can be taken: repair the bottom valve, remove the sludge, correct the steering, and clean the impeller.
