一、工作原理
主螺杆随外界电机做旋转运动(并带到两根负螺杆),随着螺杆螺旋槽周期性打开,吸入腔容积增大,形成真空,真空的压力差将介质被吸入螺旋槽内,并被螺旋槽封闭住,随着螺杆的旋转,介质随螺旋槽沿螺杆轴线向出口移动,最后介质被排除泵外,这就是三螺杆泵的工作原理
二、进出口多种组合形式,方便现场管道连接
右出左进:常规使用,无进口代号
左出右进:反向进口,进出口代号为Z
端进上出:尾端进口,进出口代号为D
(备注:进出口相对位置方向为从驱动电机端向泵方向观察)
三、多种安装方式,更好的满足工况要求
卧式安装【H】:同意普及型,公共底座连接
支架式安装【F】(也称法兰式):减少机组面积,同轴性好
立式安装【S】:大大缩小安装所需的横向空间,同轴性好
四、螺杆泵的开机、关机及停机
1.开机前的准备
1.1灌泵
【注意:因为螺杆泵(特别是内置轴承的三螺杆泵)不容许干运行!所以首次开机,必须向泵中加注介质】
开机前,若用于泵试验的介质(请参考性能试验报告)与泵送介质化学不兼容,则操作员应仔细彻底地清洁泵。通过泵体孔或出口管灌泵,应灌至介质浸没并排出空气。灌注高度必须保证吸入侧在泵运行前和运行时都有足够的覆盖。
泵长期搁置后,泵里的介质会蒸发掉,或者在修理后,应该重复灌泵过程。
1.2转动方向控制
驱动电机转动方向应与泵上转动方向箭头指示一致。可通过打开进出口阀瞬时接通电机来检查转动方向,若转向错误,则泵没有吸力,这将损坏泵。三相电机的旋转方向可通过调换电源任意两相来改变。
1.3接通所有的辅助装置
开泵前,如果泵带有部分附属装置,则必须使所有加热/冷却/冲洗/泄压系统投入运行。
提示:保证流量/温度/和压力与订单数据表相一致或遵循制造商的操作说明书。
2.开机
2.1启动
在启动前,要完全打开泵吸入侧和压力侧的所有开关装置。
内置安全阀的泵,一般安全阀掉启跳压力设定为工作压力+10%,而HSHD系列安全阀是按用户要求设计执行。只要压力管道中有截止阀或有阻塞的可能性而导致压力升高,就必须安装安全阀。
启动时,系统出口侧安装的排气阀必须打开直到泵吸入侧的空气排完,如有液体从中冒出就可关闭该阀。因泵是自吸式的,无需反压就可自动排气。
检查贮液罐中的液位,当系统运行时,该液位不能低于限定的最小值,否则应添加至所需量。
3.停机
关闭电动机,确认泵平稳停转。
若出口管中安装有止回阀,则截止阀可保持打开状态;相反应关闭。
停止相关的附属装置(如:加热/冷却/冲洗系统等)。
