Reasons for wear of the single-coolant pump casing

The reasons for the wear of the casing of a single-coolant pump may include the following: 1. Corrosion by the fluid medium: If the fluid inside the pump casing is corrosive, its prolonged action can cause severe wear and corrosion on the surface of the casing. This may be due to the presence of corrosive substances such as acids, bases, and salts in the fluid, or an excessively high temperature of the medium, which causes the pump casing material to be unable to withstand it. 2. Improper operation: The operator used the pump incorrectly, resulting in wear of the pump casing. For example, frequent start-stop operations or sudden shutdowns can increase the impact force of the liquid flow within the pump, thereby accelerating wear on the pump casing. 3. Improper selection of pump casing material: If the material chosen for the pump casing is incompatible with the fluid medium, it can also lead to wear of the pump casing. When selecting the material for the pump casing, factors such as the corrosiveness of the medium and temperature must be taken into account to choose a material with appropriate corrosion resistance. 4. Equipment aging: The pump casing may age over time as a result of prolonged use, leading to a decrease in the material’s strength and corrosion resistance, which in turn causes wear on the pump casing. Since it is not possible to directly observe the wear condition of the pump casing, it is recommended to determine whether there is wear by measuring parameters such as the pump’s vibration and noise, and to carry out repairs or replace the pump casing in a timely manner to ensure the proper operation of the pump. At the same time, appropriate measures should be taken based on the specific circumstances, such as replacing the pump casing material with a more suitable one or improving the operating methods, in order to prevent further wear of the pump casing. .
