Please help to address the 4 issues related to the pump, dear Haiyou
Thread Content
We have this type of pump on site. May I ask: 1. Does internal leakage of the mechanical seal refer to leakage of the circulating medium? 2. Does external leakage of the mechanical seal refer to leakage of the cooling water for the mechanical seal? 3. Is the cooling water for the mechanical seal used to cool the contact surface between the stationary and rotating rings? 4. Is the grease added inside the pump used to cool and lubricate the bearings?
1【Does internal leakage of a mechanical seal refer to the leakage of the circulating medium?】It refers to the situation where a mechanical seal equipped with a cooling system (other than those with self-flushing functionality) allows cooling water to leak into the medium (inside the pump).
【2. Does ‘external leakage of the mechanical seal’ refer to the leakage of the cooling water for the mechanical seal?】: It refers to the situation where a mechanical seal is equipped with a cooling system, and the cooling water leaks out. Did not enter the medium.
【3. The cooling water of the mechanical seal is used to cool the contact surface between the rotating and stationary rings, right?】 This means that in a mechanical seal with a cooling system, the cooling water is used to cool the entire mechanical seal chamber, while the medium itself is used for self-flushing the contact surface between the rotating and stationary rings.
【4. Is the meat added inside the pump used to cool and lubricate the bearings?】 Yes,
The reply upstairs was very detailed; I’ve learned a lot from it
External leakage can be seen with the naked eye; how can internal leakage be detected? The normal pressure of the pump, the pressure of the seal water, pH, and odor? Thank you
