Constant flow blanking plug is an important component in the layered water injection system of oil field, when the injection pressure and strata pressure are changing, it can ensure that the flow rate of injection is nearly constant, so getting the purpose of constant flow injection. 恒流堵塞器是油田分层注水系统中的重要部件,在注水压力和地层压力变化时,它可以保证注水流量基本不变,从而达到恒流注水的目的。
It is important to maintain a constant pressure differential through the tank during the process of fertilizer injection for obtaining a uniform fertilizer distribution in a micro-irrigation system because the pressure differential is the primary factor affecting the decrease of fertilizer solution concentration with time. 由于压差是影响肥液浓度变化的最主要因子,为了在微灌系统内获得均匀的肥料分布,保证施肥开始后和施肥过程中压差稳定至关重要。
