[Asia Pump Network News] Why water ring vacuum compression phenomenon? Compression can appear when there are any solutions? Small partners all know? Xiaobian today and find out about it. Water ring vacuum pump compression phenomenon and solution Compression phenomenon is divided into over-compression phenomenon and under-compression phenomenon. 1, the phenomenon of over-compression Closed cavity does not reach the exhaust port, the gas has reached its exhaust pressure. (Usually occurs in large pumps, and suction pressure is high when prone). 2, under-compression phenomenon Closed small cavity connected with the exhaust port, but the gas has not yet reached the exhaust pressure (often occurs in the suction pressure is low). Experts believe that the above phenomena and inhalation gas pressure changes, while the pump position of the two (compression ratio) is fixed. Bring problems: consume more power (waste of energy), reduce pump pumping efficiency. Solution 1, set the rubber ball valve in front of the exhaust port: when the gas in the small cavity reaches the exhaust pressure too early, the ball valve opens. 2, the use of flexible exhaust valve design (patent), to avoid over-compression phenomenon. Flexible exhaust valves reduce pump energy consumption by automatically adjusting exhaust area. To achieve the best operating efficiency. 3, the design, the lowest suction pressure (limit pressure) to determine the pump compression ratio (exhaust port position). Compression ratio = P out / P into = V into / V out Design time: P into the ultimate pressure (Editor: Pure) Read More: 2016 Beijing Petroleum Exhibition Pumps and Valves Pipe Fittings Exhibition Information 2016 Exhibition Information
