概述
三螺杆泵是一种容积式泵，具有结构简单，体积小，允许高转速，平稳可靠，压力脉动小，流量积小，允许高转速，平稳可靠，压力脉动小，流量螺杆啮合的原理，依靠旋转的螺杆在泵套内相互啮合，把输送的介质吸入并封闭在啮合腔内，沿螺杆轴向匀速的推向排出口以及在排出口形成稳定的压力。
三螺杆泵仅适合于常温下输送不含固体颗粒的润滑性液体，可作为一般输送泵，液压传动装置中的供压泵。公司经过多年研究开发的3QGB系列保温高黏度三螺杆泵，是在三螺杆泵的基础_上对螺杆与泵套之间的配合和主螺杆与从螺杆之间的配合进行优化，使其可以输送高温、高黏度的介质。
3QGB系列保温高黏度三螺杆泵主要用于输送高黏度的润滑性液体，常作为沥青、重燃油、重齿轮油、重柴油的输送泵，该泵内部设有保温腔室与保温通道，允许气体或液体作为热载体，最高工作温度≤350C。高黏度介质一般通过加温降黏度后输送，输送黏度-般为3.0~ 760mm/s。
我公司3QGB系列保温高黏度三螺杆泵型号从进出口径DN40到DN300，流量2.8m/h到300m/h各种型号齐全，可满足不同客户的需求。
型式代号
订货应提供如下数据:
·介质的特性(温度、腐蚀等)
·工作温度下介质的黏度
·泵的进出口压力
·泵的工作流量
·泵的安装型式
·配套要求
选泵要点：根据油品的黏度选择适当的泵转速，以保证泵的NPSHR能满足用户的实际吸入条件。介质黏度大于760 mm'/s时，请与我厂联系，我厂帮助用户选泵。
三螺杆泵配套部件BJ643H系列气动保温三通阀
根据沥青高黏度的特性，公司从实际情况出发，在现有阀门的基础上，吸收国内外先进思想，研制开发出了用于输送高温沥青的BJ643H系列气动保温三通阀，以大幅提高我国沥青拌和设备沥青系统的生产效率
BJ643H系列气动保温三通阀连接结构采用法兰连接，阀体材料为铸钢。阀芯为铝合金材料，在使用过程中阀芯会根据阀体不锈钢密封面做自动调整修复,从而延长使用寿命。气缸和活塞都是按照阀门参数设计定做，保证阀门能最佳的开启和关闭，进一步延长使用寿命。立柱及阀杆材质为不锈钢，保证阀门在恶劣的环境下不被锈蚀，可正常使用。活塞杆上安装的弹簧不仅保证了阀门在0.3MPa到1.0MPa压力之间的使用，也起到了缓冲作用，保护了阀芯和活塞，同时在气缸失气的情况下，可以封住出油回路。
BJ643H系列气动保温三通阀利用活塞在气缸中形.成两个密封腔，通过两个密封腔的压力差达到阀门的开启和关闭，并且在气缸的上下盖配有限位开关，不仅保证了阀芯的位移，也实现了自动化控制。
