一, unique sealing device
ZJW series filter press for filling pressure impurity pump adopt external loop, not pressure water supply and anhydrous mechanical seal mechanical seal forms, according to its working condition is different, its design principle is different, need comprehensive consideration of filter press six kilograms of pressure, the pressure water supply mechanical seal, the water in the tank, according to its using the circulation, save water, and to rely on mechanical seal components, reduce the pump for the pump shaft seal pressure, its service life is greatly improved, and ensure the shaft seal leakage.
二, the structure of the two stage impeller design
ZJW series filter press for filling pressure impurity pump impeller with double column form, depending on the double impeller flow is consistent, lift the principle of superposition, completely solve the single pump impeller pressure slants small, in the early filling pump due to the working condition, to pressure is not enough, the violent vibration and noise is too large; And when running normally, single pump and existence can't satisfy the stress and lack of capacity, in narrow impeller fluid passage, slurry through the defect in the poor performance. Double impeller press filter feeding pump design completely solved the shortcomings of the single pump, and for the press filter into the material resulting from the resistance when the large flow, low head and normal after the operation, for slurry pump has little change of flow and high pressure.
So from the design, ZJW series filter press for filling pressure impurity pump is designed specifically for filter press feed pump.
三, long service life
Due to the higher cost when the pump is single head from fluid mechanics research, when the pump head high, for pump abrasion quantity will increase, and due to the instability of single pump in feeding, leading to a single pump wear fast, short service life, and so on and so forth. Its double pump impeller press filter feeding from the design principle is low on the impeller outlet velocity obtained high outlet pressure, thus overcome the single impeller for supercharging pressure and increase the linear velocity of the impeller flaw, thus reducing the impeller and volute wear faults, effective
Was high slurry pump flow (impeller and volute, guard) life. ZJW series filter press for filling pressure impurity pump or composite slurry pump high wear-resisting material, according to different working condition, the impeller and volute, the former guard, guard after adopting A05, A07, KmTBCr27 high chromium alloy materials. |
