3GL、3GF、3GLBW立式三螺杆泵概述

3GF法兰式三螺杆泵、3GC法兰液压平衡型三螺杆泵、3GFBW法兰保温型三螺杆泵(简称:3GF、3GC、3GFBW法兰式三螺杆泵);3G保温沥青螺杆泵、3GR反向旋转型保温沥青螺杆泵、3GBW(LQ3G) 保温沥青卧式三螺杆泵(简称:3G、3GR、3GBW保温沥青螺杆泵),3GBW保温沥青螺杆泵又称LQ3G沥青螺杆泵;3GL立式三螺杆泵、3GF加强型立式三螺杆泵、3GLBW保温性立式三螺杆泵(简称:3GL、3GF、3GLBW立式三螺杆泵);以上三个类别的三螺杆泵都是容积式泵的一种,显著的优点是结构简单、体积小、允许高转速、工作平稳可靠、压力脉动小、流量稳定、噪音低、效率高,是高粘度保温泵。LQG系列三螺杆泵、保温型沥青泵特别适用于沥青库、油田、重油等油库和导热油蒸汽加热,沥青,重油等设备配套。它是利用螺杆齿合原理,依靠旋转的螺杆在泵套内相互啮合,把被输送的介质封闭在齿合腔内,沿螺杆轴向连续匀速地推至排出口,为系统提供稳定的压力。上海美言壹泵阀生产的三螺杆泵具有良好能力的容积式低压转子泵,适用于输送具有润滑性无固体颗粒杂质的各种燃料油、乳化液、重柴油、液压油、机械油等。粒度范围可达3~760mm2/s;输送介质的压力在5.0MPa以内,高粘度介质可通过加温降粘后输送,其温度一般不超过150℃。

3GL、3GF、3GLBW立式三螺杆泵适用范围及对比优点:

(1)压力和流量范围宽阔,流量范围0.2~320m3/h最高工作压力可达5MPa;

(2)运送液体的种类和粘度范围宽广,粘度范围1mm2/s-760mm2/s;

(3)因为三螺杆泵内的回转部件惯性力较低,故可使用很高的转速;

(4)吸入性能好,具有很强的自吸能力;

(5)流量均匀连续,振动小,噪音低,几乎没有脉动;

(6)三螺杆泵结构坚实,安装方便有(卧式、立式、法兰式、插装式)保养容易;

(7)三螺杆泵具有很强的耐热性,一般工作温度是(1~250°C)超过此温度需特制;

(8)根据所输送介质需要还可提供加热或冷却结构;

(9)三螺杆泵几乎没有磨损,三螺杆泵只要选型正确,使用寿命长。

(10)三螺杆泵的工作效率高。

与其他泵对比优点:

1.和离心泵相比螺杆泵无需安装阀们流量是稳定的线性流动

2.和柱塞泵相比螺杆泵具有自吸能力强、吸入高度强

3.和隔膜泵相比螺杆泵可输送各种混合杂质含有气体及固体颗粒或纤维的介质,也可输送各种腐蚀性物质

4.和齿轮相比,螺杆泵可输送高粘度的物质

5.和柱塞泵,隔膜泵及齿轮泵不同的是,螺杆泵可用于药剂填充和计量

3GL、3GF、3GLBW立式三螺杆泵用途及特点

3G、3GR、3GBW(LQ3G)三螺杆泵广泛应用于石油、化纤、冶金、机械、电力、机床、船舶、玻璃、公路等各行各业。三螺杆泵适用于输送燃料油、润滑油、液压油、原油、沥青及其他类似油的润滑性液体。三螺杆泵在工业领域中作润滑泵,在液压系统中作液压泵,在燃油系统中作输送及增压泵;在输油系统中作输送及加油泵。流量范围0.2~250m³/h,最高工作压力可达4mpa。

1.没有困油现象,流量和压力均匀,工作平稳,噪声和振动较小。

2.轴向吸入,不存在离心力对液体吸入的影响,吸人性能好。 且无往复运动部件和泵阀,故适用于高转速,因此螺杆泵的流 量范围大,常用回流法调节流量。

3.三螺杆泵受力平衡和密封性能良好,n、高,允许工作压力高,可达20MPa, 特殊的可达40MPa。单螺杆泵和双螺杆泵额定排出压力不宜太高,前者最大不超过2.4MPa; 后者通常不超过1.6MPa。

4. 注意起动及停车时的开关阀顺序( 起动前吸排阀全开; 停用时断电后先关排出阀,完全停转后关吸入阀,防止被内液体吸空)。为轻载起动,在起动前将安全调压阀调整松,达到额定转速后调至要求压力。

5. 螺杆较长,刚性较差,易变形。安装时注意间隙均匀,大流量泵重心线尽可能通过船体肋骨;吸排管路   应固定并与泵吸排口对中;螺杆起吊时防止受力弯曲;备用螺杆应悬吊保存。使用中应防止过热。

6.防止油温太低、粘度过高、滤器脏堵等。

3GL35、3GF35、3GLBW35立式三螺杆泵启动

1.首先检查现有操作条件是否与铭牌上的设计数据相符合。

2.按泵上铭牌指示,给泵注入工作介质或润滑脂,初次启动新泵或者长期(六个月以上)停用的泵在使用前,必须给泵灌满工作介质或者润滑。这可为为启动是提供必要的液体密封,保证泵能够自吸且是泵内各运动零件得到润润滑。

3.检查管线连接是否正确,启动前打开所有进出口管道上的阀门。防止因空转或压力超高导致泵发生故障。

4.点动,检查电机的旋转方向和接线盒接线方式。

5.如泵上装有安全阀(当排出管道上有可关闭的阀时,有必要安装安全阀)其开启压力超出工作压力10%,这在出场试验时已经确定。开启压力可有阀上的调节螺钉调节。


3GL35、3GF35、3GLBW35立式三螺杆泵维护和控制

1.泵的密封形式为机械密封时,密封强的温度应不超过80℃。轴封处点滴漏泄属正常现象,(一般漏泄量不大于10m/h).如泵的漏泄量过大时则需重新安装或更换机械密封。

2.泵的轴封是内置时,轴承由所属送的液体润滑,如果泵的轴承是外置的,则轴承需润滑脂润滑,润滑脂在油杯处定期加入,正常使用条件下,轴承的设计寿命约为24000小时。

3.对于间歇性操作、高温、低粘、润滑性差的介质及相似介质,泵的使用寿命可能会缩短,应此我方建议定期检查泵的噪音和轴承处的温度(80℃)。

4.如果啪啪声或隆隆声代替了泵正常工作时的嗡嗡声,或者轴承处的温度急剧升高,这说明轴承出了故障,应尽快更换轴承。

5.对于水电行业用泵,调阀时一定要控制油温,油温不得超过46℃,超过此温度后,油粘度降低(约15cst),泵容易发生抱轴现象,应此,油温超过46℃后,必须启动冷却系统。

6.泵上所带安全阀只作为一种保护机构,一般不需用户自行调整。

7.如长期不工作时,应进行油封,并定期检查油封情况,必要时重新油封。
