----Problems with pump cooling water----
Thread Content
For the plant’s wastewater treatment renovation, a batch of slurry pumps were delivered. Due to limited on-site conditions, water supply is not possible. Perhaps due to communication issues, these pumps happen to all be double-ended with water cooling. There is no water available right now. The supplier proposes the following solution: 1. The double-end face water-cooled seal can allow oil to pass through ； Since there is no water, use oil instead ； 2. Remove one end face, remove the water cooling system, adjust the seal, and configure it for use as a single-end face mechanical seal. Personally, I lean towards the first option. But is it effective? Is oil circulation similar to water circulation? Please ask an expert in the field to help answer.
Oil cooling is the same as water cooling; this can be achieved, and many manufacturers use oil cooling in their designs. The second option is meaningless; single-face mechanical seals carry a high risk of leakage
Is there no tap water on site at all? Just find a hose to connect to the tap water. The first solution works, but your oil must be pure and free of impurities; otherwise, it will quickly damage the mating surfaces of the mechanical seal. After it passes, heat can be removed, but it seems like a waste. The second option is more complicated to modify, as the pump needs to be sent back to the factory for remanufacturing.
I’m not familiar with the equipment, but it seems like changing the oil is troublesome, and cleaning it as well is troublesome. It’s much more convenient to just lay a pipe!
In the case of wastewater, since the medium contains many particles, it is recommended to install pipes; then remove one pair of mechanical seals and use the cooling water as water for flushing these seals. This approach helps to prevent impurities from causing wear on the mechanical seals, while also ensuring that their temperature remains within the appropriate range
Build a circulating pool. . . . . . . . . . . .
It depends on whether the medium being transported is dangerous and whether the temperature is high. If there is no risk of leakage and the temperature is not high, the second option is recommended – no water or oil needed, which makes things simpler!
