Eccentric reducer rubber joints and the role of the main performance: 1. pipe - pump installation eccentric head: is used to prevent cavitation, and pump the size of imports should be the top level installation of the first general, this is to prevent the gas at the pump inlet pipe accumulation, the formation of large bubbles into the pump chamber, damage to the pump. Only one case, the bottom level can only be installed. That is connected up directly behind the head size bent elbow. This case, gas can not accumulate. 2 pumps - installed concentric reducer pipe fittings: pump outlet conduit system with DN there are differences for concentric reducer size head, two tubes of different sizes to achieve a direct connection, to achieve the adjustable pipe fittings.
