一、概 述 Summary

JLCZ型化工流程泵是单级单吸悬县臂式离心泵,是更新换代的节能产品,适用于化工、石油、淀粉制糖、味精、制药、酿酒、合成纤维等部门输送温度在-20~105℃的腐蚀性介质或物理、化学性能类似于水的介质。

Type JLCZ Chemical Process Pump is Single-stage single-suction cantilever centrifugal pump, and the most popular energy-saving products. The pump is widely used in chemical,petrochemical, Starch sugar, MSG,medical, Spirit-making, synthetic fiber etc., for transfer corrosive or pure medium at -20oC~105oC (temperature of medium).

JLCZ型化工流程泵的性能范围(按设计点) Performance range 流量:3.6-1300米3/时 Capacity:3.6-1300m3/h 扬程:5-125米 Head:5-125m

泵的最高工作设计压力为1.6兆帕

Maximum working pressure (designed): 1.6 MPa

用户可发根据被输送介质的腐蚀性程度对泵的过流部门主要零件选用不同材料。泵的过流部门主要零件的材料及其代号有下列五种:

二、结构说明 Structure Description

JLCZ型化工流程泵一种单级单吸悬臂式离心泵,其有关标记,额定性能参数和尺寸均采用ISO2858-1975(E),泵体通过下部的底脚支承固定在底座上,泵的进口方向水平方向,泵的出口方向为垂直向上,与密封腔连成一体的泵盖采用后开门式,即夹紧在泵体与悬架之间。叶轮经过静、动平衡校验,用叶轮并帽和锁母与轴套一起固定在轴上。泵轴由两列或三列轴承支承在悬架部件中,悬架部件通过悬架支架泵体一起固定在底座上,泵体以及悬架部件与悬架支架均由螺母栓连接。轴与电动机由联轴器联接。

Type JLCZ Chemical Process Pump is Single-stage single-suction cantilever centrifugal pump, the mark, rated performance parameters and dimensions according to ISO2858-1975(E), the pump through the bottom of the foot support fixed to the base, Inlet direction of pump is horizontal direction, the export orientation is vertical, with pump cover to structure, and using back-opening, that clamp in between the Casing and suspension. Take safe cup of impeller, lockingnut and shaft sleeve to fix on the axle, after impellers balance check at static and dynamic.Two or three bearings support the shaft in the suspension parts. Suspension parts and Suspension bracket for Casing fix on baseplate, they are by a bolt to connection. The shaft and motor connect with coupling.

泵的密封型式要用单、双端面硬质合金机械密封,也可由用户根据需要选用,同时根据需要允许适合于ISO3069规定的密封腔尺寸的其他结构的轴封形式(如带波纹管的机械密封和付叶轮密封等等)。
