Generally, high negative pressure is required in the mine, and many vacuum pumps can not meet the requirements. However, the water ring vacuum pump is not the same. It is developed for the mine. However, it is inevitable that pollutants will be produced in the process of use. The oil pollution is more difficult to be clear. However, as long as we timely prevent it, we can avoid the occurrence of this phenomenon How to prevent oil pollution
I. The joint of the pipeline shall be sealed with more sealing pads, and there shall be no air leakage or water leakage.
2. Install a vacuum gauge at the suction port of the vacuum system, so as to master the change of vacuum.
3. When installing or repairing the pipeline, be careful to clean the surrounding area to prevent foreign matters from falling into it.
IV. install valve on the pipeline of suction port
1. When the vacuum degree reaches the limit, there will be a lot of noise, which is called cavitation noise. The vacuum degree is adjusted through the valve.
2. When the vacuum degree is high, the pressure test blasting detector opens the valve to release appropriate amount of gas, and the cavitation sound disappears immediately. When the vacuum degree drops, the valve is closed.
5、 Circulating water
When the water temperature of the circulating water exceeds 40 degrees, the vacuum degree will drop. If the water temperature of the circulating water exceeds 40 degrees, the vacuum degree will drop. Timely supplement or replace the cold water to reduce the temperature of the circulating water. The water ring vacuum pump on the fence equipment mostly uses iron oil bucket to hold the circulating water, and the water in the bucket should be more.
Water ring vacuum pump with high negative pressure and small flow rate is suitable for use in mines with small pumping volume and high negative pressure. For oil pollution, it needs a lot of energy, time and resources to clean it. Only by doing a good job of prevention in daily life can we reduce troubles and save costs.
