In the piping system equipped with cyclone, slag removal system, divssure filtration dewatering system also requires a certain amount of divssure at the outlet of the pipeline. Therefore, divssure gauges should also be installed in such systems to monitor whether the divssure meets the requirements. In the installation of slurry pump, must be in accordance with the relevant instructions to implement, otherwise it will bring the consequences of half the effort. Today, the small series for you to share the installation steps and key points of the single-stage slurry pump, 1. Check the installation of the slurry pump mechanical seal model, specifications are correct. 2. Check that the size accuracy, geometric accuracy and correlation of the slurry pump and the installation of the mechanical seal are in accordance with the technical requirements. (1) The radial beat tolerance of the shaft (or bushing) for the installation of the mechanical seal, the surface finish of the shaft (or bushing) and the dimension tolerance of the outer diameter. (2) The sealing city and the cover are combined with the positioning end to face the vertical tolerance of the center line of the shaft (or bushing). (3) Install the end of the shaft (or bushing) of the dynamic ring seal ring.
一、ZJ渣浆泵概述
ZJ渣浆泵的形式分为两大类,一类是ZJ渣浆泵,为轴向单极单吸离心式渣浆泵;另一类是ZJL渣浆泵,为立式轴向单X单吸离心式渣浆泵。渣浆泵以其X的水力设计、结构设计达到了节能的显著效果,又以渣浆泵材质X良、硬度高、耐磨性好、运行平稳、加工工艺可靠等特点,深受用户X。渣浆泵技术可广泛应用于电力、冶金,煤炭、石油、化工、采矿、工业锅炉、河道疏通等X域。wjhuiquan3.21
二、ZJ渣浆泵的用途和适用范围
渣浆泵系列在水力设计、结构设计以及所用耐磨材料上,综合应用了同类产品的X点并加以创新,具有节能、振动小、噪声低、运行可靠、使用寿命长、方便等特点,渣浆泵的综合性能居国内水平,大部分泵的效率指标居X水平。可广泛用于电力、冶金、煤炭、建材等行业输送含有固体颗粒的浆体。如火电厂水力除灰、冶金选矿厂矿浆输送、洗煤厂煤浆及重介输送等。其允许输送的浆体重量浓度Cw为:灰(渣)浆和煤浆45%;矿浆和重介60%。

(1)安装机械密封部位的轴(或轴套)的径向跳动允差,轴(或轴套)的表面光洁度和外径尺寸公差。(2)密封腔和压盖结合定位端面对轴(或轴套)中心线垂直度允差。(3)安装动环密封圈的轴(或轴套)的端部,安装机械密封的壳体孔的端部结构之倒角和光洁度。(4)机械密封之转轴工作时的轴向位移量。3.在安装渣浆泵中,保持清洁,不允许用工具敲打密封元件,以防损伤和。4.安装时,动、静环表面应涂上一层清洁的机油和透平油。辅助密封圈(包括动环密封圈和静环密封圈)安装前也需涂一层清洁的机油或透平油,以保证安装顺利。5.将静环密封圈套在静环背部后,装入密封端盖内,要注意勿伤静环端面,要保证静环端面与端盖中心线垂直。
三、从近几年来泵站的运行情况看,ZJ渣浆泵有以下X点:
1、ZJ渣浆泵效率高,节电效果明显。泵站运行电流平均下降30A,效率指标高出国内同类及国外相应泵2-10个百分点。
2、ZJ渣浆泵过流部件寿命长。一般能连续运行3000-4000小时,其寿命是12P-7型泵的5倍以上。
3、ZJ渣浆泵运行平稳、振动小、噪音低、了泵站的工作。
4、ZJ渣浆泵轴承箱结构合理,密封好,运行温度低。轴承使用寿命是12P-7型泵使用326轴承的9倍以上。
5、渣浆泵过流部件设计合理,拆卸方便。ZL型渣浆泵是节能降耗,效益的好产品,建议广泛推广。
切忌盲目操作。泵机组应采用二次灌浆法进行安装。安装后,机组的中心线应与地基中心线一致;机组的中心高与设计值的偏差应不大于±2mm,机组的水平允差为0.1/1000。对于采用联轴器直联传动的泵机组,机组的同轴度一般靠联轴器找正来保证。一种是以刀口尺与塞尺配合。以刀口尺找正联轴器的外圆,保证每对联轴器在各方向的平齐,其误差δ应不大于0.10mm[图3,(a)]。以塞尺检查每对联轴器之间的间隙,其误差Δ(Δ=δ1-δ2)应不大于0.10mm[图3,(b)]。另一种是用磁力百分表配合塞尺找正联轴器。将磁力百分表固定在一边联轴器外圆上并盘车,百分表测头对面联轴器外圆上,观看百分表的跳动不应大于0.15mm[图3。

Install the chamfering and finish of the end structure of the mechanically sealed shell hole. (4) Axial displacement during the operation of the rotating shaft of the mechanical seal. 3. In the process of installing the slurry pump, keep clean, do not allow the use of tools to beat the sealing elements to divvent damage and damage. 4. When installing, the dynamic and static ring surface should be coated with a layer of clean oil and turbine oil. Auxiliary sealing rings (including dynamic ring seals and static ring seals) should also be coated with a layer of clean oil or turbine oil before installation to ensure smooth installation. 5. The static ring seal trap in the static ring back, loaded into the sealing end cover, to pay attention to do not hurt the static ring end, to ensure that the static ring end and end cover centerline vertical, and pay attention to the static ring back of the anti-grooving groove to be aimed at anti-resale, but can not contact. 6. The rotating part of the mechanical seal, depending on the two fixing screws on the spring seat and the shaft fixed, tighten the fixing screws, to ensure the working length of the spring. Whether it is a single-stage slurry pump or a multistage slurry pump. Only strict compliance with operating norms.
