Water ring vacuum pump selection points

Water ring vacuum pump is a rough vacuum pump, because of its simple structure, compact, small gas temperature changes, stable operation, easy maintenance, can extract flammable, dusty water gas and much Concerned about the market users like to be respected. However, currently on the market water ring vacuum pump a wide range of products, specifications, sizes, which also caused many consumers to buy the confusion, then the water ring vacuum pump purchase method is what? What should you pay attention to during the purchase? Xiaobian below to discuss with you. Water ring vacuum pump selection points Water ring vacuum pump selection method First, try to choose the lower speed specifications Same exhaust volume under the premise of a larger pump due to the larger impeller diameter, it will lead to lower pump speed Therefore, the pump with lower speed should be selected as much as possible, so the specific power consumed by the large pump is smaller, that is, the efficiency is higher. Second, the impact of water temperature should be considered As the water temperature is lower than or higher than 15 ℃ will affect the pumping capacity of the pump, combined with the majority of users in our country to add water temperature between 25 ℃ ~ 35 ℃, the pump should be selected when considering the water temperature Impact. 3, the impact of suction resistance Gas aspiration sites are often below the coal mine, far from the water ring vacuum pump (some coal mine up to a few kilometers), the suction line is too long, it should take full account of the loss of resistance to suction . 4, the exhaust when the selection of a slight positive pressure Currently the water ring vacuum pump exhaust pressure is generally 0.02 ~ 0.05 MPa · G between, and according to the water ring vacuum pump technical documents show that the exhaust pressure For a standard atmospheric pressure derived, so in the selection should also consider the exhaust pressure increases, the pump cavity backflow increases on the exhaust volume impact.
