[0001] The application relates to the technical field of self-priming pumps, in particular to a corrosion-resistant horizontal centrifugal self-priming pump. BACKGROUND
[0002] A vertical self-priming pump, whether made of stainless steel or high polymer plastic material, must be filled with water to form a vacuum state before work so as to normally work. Therefore, water replenishment before each use is particularly cumbersome, time-consuming and laborious, and the pump material is particularly high in corrosive environment. Water replenishment is required before each pump opening, the inlet pipe needs to be equipped with a bottom valve, and in an industrial sewage treatment plant, especially in a sludge pool at the bottom of the acid or acidic wastewater adjusting tank, the bottom valve needs to be lifted for maintenance every time the bottom valve fails. When the vertical pump self-priming pump replaces the impeller, the vice impeller and other parts, the crane needs to be used to remove the motor for maintenance, and the crane table cost is high.
