產(chǎn)品簡介及特點Product Introduction and Features PTCZ系列標(biāo)準(zhǔn)化工流程泵是我公司結(jié)合國外先進技術(shù)在IH泵基礎(chǔ)上改進設(shè)計而成。其結(jié)構(gòu)形式為臥式懸架，徑向剖分、后開門、單級單吸化工離心泵。符合AP1610以及ISO2858/DIN24256標(biāo)準(zhǔn)。綜合性能全面超過IH泵。 采用圓柱滾子軸承和背靠背推力軸承配對，甩油環(huán)稀油潤滑，承受載荷的能力強； 泵主軸軸徑尺寸充裕（重型），整機運行平穩(wěn)； 軸封采用單（雙）端面、波紋管等形式的機械密封，也可采用軟填料密封，能適應(yīng)各種條件下的密封要求； 軸向力由副葉片或平衡孔平衡，對于徑向力在的規(guī)格采取了雙殼體設(shè)計； 整個懸架包括軸、葉輪、軸封、泵蓋等形成一個組合件，可不必拆卸管路就能進行泵檢修維護，當(dāng)采用加長聯(lián)軸器時，電機不必拆下； 泵法蘭采用PN16和PN25兩種壓力等級（隨材料而變），也可適用于ANSI標(biāo)準(zhǔn)125或150等級。 Series PTCZ standard chemical process pump is improved and designed by our company on the basis of IH pump by combining foreign advanced technique. Its structure is horizontal fame mounted, radial split, back pull out and single-stage single-suction chemical centrifugal pump. It complies with AP1610, ISO2858 and DIN24256 standards. Its comprehensive performance fully exceeds the IH pump. It adopts column rolling bearing and back to back thrust bearing to be a collocation, oil lubrication with a throwers it has high load bearing capability. Pump shaft diameter is sufficient (heavy) duty, the whole machine operates stably. Shaft sealing adopts single (double) face, bellow type mechanical seal, it also can adopt soft packing, is can meet sealing demands of all kinds of conditions. Axial force is balanced by back vane or balanceable hole, for the specification with big radial force; we adopt double-wear passage design. The whole frame contains shaft, impeller, shaft seal, and pump cover to be an assembling list, so pump can be checked and maintained without dismantling pipeline. When a spacer coupling is used, motor can not be dismantled. Pump flange adopts PN16 and PN25 two pressure grades (it varies with different material), it also suits class 125 or 50 of ANSL standard.
