Our company has around ten such vacuum pumps, and the monthly water usage is approximately 15,000 cubic meters. What issues need to be considered if recycled water is used?
I have carried out modifications for similar situations in my company; the costs were recovered quickly and wastewater discharge was reduced. There is no need to use water as a circulating fluid; liquids with a high boiling point, low volatility, that do not react with the material gases, and moderate viscosity can be used in place of water, and the results are excellent. But make sure the cooling system meets the requirements. Where is your company located? Tell me to go handle it; as long as there’s food provided, that’s fine. Hehe
What alternative liquid is used upstairs? Could you share it?
It varies depending on the operating conditions and the type of liquid; it cannot be generalized.
A small cooler can be shared for cooling; water at a temperature above 0 degrees is sufficient, and our company uses water at 7 degrees
I don’t know what the original poster is talking about. For the cooling water of water ring vacuum pumps, circulating cooling water or ice water is used, depending on the operating conditions. With such high water consumption per month, isn’t it necessary to implement a recirculating cooling system instead of discharging the water directly? You do things like this too? Not much water needs to be added to the working fluid, so I don’t understand what the original poster is asking.
It refers to the liquid ring water inside the pump, which becomes wastewater due to contact with the gaseous medium being pumped.
I’ll share some personal opinions for reference only. Since the poster has not specified the medium to be pumped by the vacuum pump, it is difficult to answer some questions. If a closed-loop system is to be used, and the vacuum pump is to operate for an extended period of time, then a heat exchanger must definitely be installed. First, it is necessary to determine whether you have cooling water available (not the working fluid), as well as what the temperature of that cooling water is; based on this information, the appropriate type of plate heat exchanger can be selected. If the medium being pumped could cause significant contamination of the vacuum pump’s working fluid, it is recommended not to use a closed-loop system.
