泡沫混凝土专用挤压管是软管泵最核心的部件，软管泵任何部件的设计可以说都是为了延长软管使用寿命来考
虑的。软管过紧会增加泵和软管的应力，减少软管的使用寿命，并增加轴承的负荷；软管过松会降低泵的工作效
率，并有回流的风险，同样还会减少软管使用寿命。
Special extrusion pipe for foam concrete is the core of the hose pump components, hose pump any part of the design
can be said to be in order to extend the life of the hose to consider. The hose is too tight will increase the pump and
hose stress, reduce the hose life, and increase the bearing load. Loose hoses reduce pump efficiency and risk of
backflow as well as hose life.
