What are the start-up preparations for diesel engine fire pumps?

There are many structural types of self-priming pumps, among which molten salt pumps, vacuum pumps, submerged pumps, metering pumps, gear pumps, corrosion-resistant pumps, acid-resistant pumps, and fire pumps flow in the direction of rotation. Then it joins with the water from the right return water hole and flows along the volute. This repeated cycle gradually exhausts the air in the suction pipeline, so that the water enters the pump to complete the self-priming process. Sewage pump self-priming pump oil pump diaphragm pump screw pump gear oil pump pump is the same, the difference is that the return water does not flow to the outer edge of the impeller, but flows to the inlet of the impeller. When the internal mixing self-priming pump is started, the return valve at the front and bottom of the impeller must be opened, so that the liquid in the pump flows back to the inlet of the impeller. Here the air is expelled and the water is returned from the return valve to the impeller inlet. This is repeated until the air is exhausted, and the water is sucked into the internal-mixed self-priming pump. The working principle is the same as that of the external-mixed self-priming pump.

ISO end-suction pumps find wide application in industries such as chemical, petroleum, pharmaceutical, food and beverage, and water treatment, where they are used for fluid transportation, circulation systems, heating, and cooling systems, among others.
