CZX型自吸装置是根据射流原理，参考国外先进技术研制的新产品。CZX型自吸装置是靠气体的喷射而实现抽气。装置体积小，重量轻，使用方便，它可直接安装在泵的机架上，与泵抽气孔连接，使无自吸能力的泵具有自吸能力，自吸装置能保证泵内充满水时，自动启动泵，并在泵启动后，自动关闭自吸装置。特别适合船用离心泵配套使用。

A Based on the jet flow principle，the CZX Type self-suction device is the latest product developed in reference to the advanced technologies of other countries。The CZX Type self-suction device realizes the suction via the jet of gas。This device features in compact structure，light weight and easy operation。It can be directly installed on the pump frame and connected to the suction hole of the pump，so that the pump without self-suction device can perform self-suction。The self-suction can ensure automatic start of the pump when the pump is filled with water. The self-suction device is automatically closed after the pump is started。It is particularly suitable to the marine centrifugal pump.
