单螺杆泵的工作原理特点及用途
The working principle of single-screw pump characteristics and uses of
单螺杆泵是一种内啮合偏心回转的容积泵，泵的主要构件：一根单头螺旋的转子和一个通常用弹性材料制造的具有双关螺旋的定子，当转子在定于型腔内绕定子的轴线作行星回转时，转定子之间形成的密闭腕就沿转子螺线产生位移；因此就将介质连续地，均速地、而且容积恒定地从吸入口送到压出端，基于这件特性，单螺杆泵特别适合于下列工况的工作。
Single-screw pump is a kind of eccentric rotation within the gear volume pumps, pump the main components: a single-head screw of the rotor and an elastic material is usually manufactured with a pun spiral stator, when the rotor cavity around the scheduled planetary rotation axis for the stator when the stator formed between the closed switch on the wrist produce displacement along the rotor spiral; so will be a continuous medium, the average rate, the volume and the constant pressure from the suction sent out the end, based on this pieces of properties, single-screw pump is particularly suitable for the work of the following conditions.
输送高粘度介质：根据泵的大小不同可以输送粘度从37000-200000厘泊的介质。
Transport high viscosity medium: According to the pumps of different sizes and can transfer from 37000-200000 cps viscosity of the medium.
含有颗粒或纤维的介质：颗粒直径可以这30mm（不超过转子偏心距）。纤维长可以350mm（相当0.4位转子的螺距）。其含量一般可达介质窖的40%，若介质中的固体物为细微之粉沫状时，含量可达60%或更高也能输送。要求输送压力稳定，介质固有结构不爱破坏时，选用单螺杆泵输送理想。
Containing particles or fiber media: the particle diameter can be 30mm (not to exceed rotor eccentricity). Fiber length can be 350mm (rather 0.4 rotor pitch). Its content usually ranging from 40% of medium pits, if the medium solids of the powder for subtle shape, the highest content of up to 60% or higher can also transfer. Requires delivery of the pressure stability, and media do not like to destroy the existing structure, the selection of a single screw conveyor is ideal. |
