Description

一种加强密封效果的单螺杆泵
技术领域
本发明涉及单螺杆泵技术领域，特别是涉及一种加强密封效果的单螺杆泵。
背景技术
螺杆泵是一种新型的输送液体的机械，具有结构简单、工作安全可靠、使用维修方便、出液连续均匀、压力稳定等优点，螺杆泵可以输送润滑油、燃油、各种油类及高分子聚合物、黏稠液体等。但目前的单螺杆泵，其吸入室、转子室和转轴仓都是分体设置的，一般通过法兰连接，再配合密封圈实现密封，密封圈存在老化的问题，从而导致漏液的情况，不仅浪费能源，还会造成环境污染，而且目前常见的单螺杆泵大多吸力差，输送高粘度流体时效果不佳。
发明内容
本发明为了解决上述问题，提供了一种密封性更好、吸力更强的单螺杆泵，所采用技术方案为：一种加强密封效果的单螺杆泵，包括依次连接的电机、转轴仓、吸入室、转子室和压出室，吸入室的壳体、转轴仓的壳体和转子室的壳体三者一体成型，转轴仓内设有转轴，转轴由电机驱动，吸入室设有物料吸入口和绕轴，转子室内设有转子和定子，转子与定子互相啮合，压出室设有物料压出口，所述转轴与转子通过绕轴连接，所述转轴和绕轴均为螺旋体结构。
本发明中，吸入室、转轴仓和转子室三者一体成型，三者之间的同心度稳定，工作过程中不易产生变形、位移，密封性效果好；本发明吸力强，可输送各种粘度流体，具有推广使用价值。
附图说明
图1 是本发明的结构示意图。
具体实施方式
本说明书中公开的所有特征，或公开的所有方法或过程中的步骤，除了互相排斥的特征和/ 或步骤以外，均可以以任何方式组合。
本说明书中公开的任一特征，除非特别叙述，均可被其他等效或具有类似目的的替代特征加以替换。即，除非特别叙述，每个特征只是一系列等效或类似特征中的一个例子而已。
如图1 所示的一种加强密封效果的单螺杆泵，一种加强密封效果的单螺杆泵，包括依次连接的电机1、转轴仓2、吸入室3、转子室4 和压出室5，吸入室3 的壳体、转轴仓2 的壳体和转子室4 的壳体三者一体成型，转轴仓2 内设有转轴21，转轴21 由电机1 驱动，吸入室3 设有物料吸入口31 和绕轴32，转子室4 内设有转子41 和定子42，转子41 与定子42 互相啮合，压出室5 设有物料压出口51，所述转轴21 与转子41 通过绕轴32 连接，所述转轴21 和绕轴32 均为螺旋体结构。
本发明在使用时，转轴仓内的转轴在电机的驱动下转动，并通过绕轴的作用带动转子转动产生吸力，将需要输送的液体从吸入室的物料吸入口吸入，经转子室进入压出室，最后从压出室的物料压出口排出。
本发明并不局限于前述的具体实施方式。本发明扩展到任何在本说明书中披露的新特征或任何新的组合，以及披露的任一新的方法或过程的步骤或任何新的组合。
