YW型液下式排污泵 Brief Introduction of YW Under-water Sewage Pumps
特点：Features
采用了独特的大通道叶轮结构，大大提高了污物通过能力，能有效地通过直径为泵口径约50%的固体颗粒
机组为立式液下式结构，可根据用户的要求采用不同的液下安装深度；
经过平衡校验的转子部件及合理的轴承布置有效的平衡了泵的径向及轴向负荷，从而保证了机组能够长期稳定的运行且振动小、噪音低；
本型泵可根据用户的要求选择不同的安装方式：单管或双管；
采用最新材料精制而成的机械密封，其使用寿命可达8000小时以上；
可根据用户的需要配备液位自动控制柜，能根据液位的变化自动控制的启动与停车，不需专人看管，使用极为方便，且易于实现自动化管理。
The impeller adopts particular large channel structure, so the drain capacity has been improved greatly, it can effectively pass the solid grain whose diameter is about 50% of the pump caliber.
The unit takes a vertical underwater structure to different underwater mounting
Depth as requested by users.
The balanced rotor part and the proper bearing arrangement have effectively balanced the radial and axial load of pump. So it ensures the unit to run long
and steadily with little vibration and low noise.
This type pump can adopt different installation forms according to the consumer’s requirements: single-pipe or double-pipe.
Mechanical seal adopts the latest material and is made with extra care, so its life is over 8000hours.
The pump can be equipped with liquid-level automatic control cabinet according to the consumer’s requirements. The whole machine can be stared and stopped automatically according to the changes of level. It doesn’t need special person to guard, so the application is quite convenient and it is easy to realize automatic management.
