渣浆泵泵头的构造泵头架构。泵体采用双层泵壳（内外双层金属构造），双泵壳外壳构造为垂直中开式，出水口位置可按45°距离，旋转8个不同位置装置运用。为有效避免轴封泄露，采用动力密封、填料密封或机械密封组合方式。叶轮与后护板问设有迷宫式间隙密封，极大地降低了浆体向填料箱泄露量，有力地保证了密封的牢靠性。叶轮设有背叶片，及时排出回流浆体，从而进步了容积率，降低了回流及冲蚀，进步了过流部件寿命。为便于检修及拆卸设有拆卸环，防止了因不能拆卸而形成割轴现象。

Pump head structure. The pump body adopts double-layer pump casing (double-layer metal structure inside and outside), the double pump casing is vertical split type, and the water outlet position can be rotated by 8 different position devices according to 45 ° distance. In order to effectively avoid shaft seal leakage, the combination of power seal, packing seal or mechanical seal is adopted. Labyrinth gap seal is set between impeller and back guard plate, which greatly reduces the leakage of slurry to stuffing box and effectively ensures the reliability of seal. The impeller is equipped with back blades to discharge the reflux slurry in time, thus improving the volume ratio, reducing the reflux and erosion, and improving the service life of the overflow parts. In order to facilitate maintenance and disassembly, a disassembly ring is provided to prevent shaft cutting due to failure of disassembly.
