Centrifugal Analysis And Emergency Pump Shutdown Steps in Chemical Centrifugal Pumps

Centrifugation is actually a manifestation of the inertia of the object. For example, the water droplets on the umbrella, when the umbrella rotates slowly, the water droplets will rotate with the umbrella. This is because the friction between the umbrella and the water droplets acts as the centripetal force for the water droplets. But if the umbrella rotates faster, this The friction force is not enough to make the water drop in a circular motion, then the water drop will move away from the umbrella to the outer edge. It is like pulling a rock with a rope in a circular motion, if the speed is too fast, the rope will break and the rock will Fly out. This is the so-called centrifugal.

The chemical centrifugal pump is designed based on this principle. The high-speed rotating impeller blades drive the water to rotate, and the water is thrown out, so as to achieve the purpose of transportation.

Emergency stop chemical centrifugal pump steps:

①Quickly press the stop button to stop the pump;

②Close the outlet valve, and wait for the pump to stop stably for 2~3 turns of the disc pump;

③ Control the liquid level of the large tank to close the valves of the inlet, cooling water, lubricating oil, etc.;

④ If the heat transfer oil pump, etc., pay attention to the temperature and safety
