进口三螺杆泵(原装进口厂家)

三螺杆泵是依靠泵体与螺杆所形成,当主动螺杆转动时,带动与其啮合的从动螺杆一起转动,吸入腔一端的螺杆啮合空间容积逐渐增大,压力降低。

液体在压差作用下进入啮合空间容积。当容积增至*而形成一个密封腔时,液体就在一个个密封腔内连续地沿轴向移动,直至排出腔一端。这时排出腔一端的螺杆啮合空间容积逐渐缩小,而将液体排出。三螺杆泵的工作原理与齿轮泵相似,只是在结构上用螺杆取代了齿轮。表为各种螺杆泵的特点和应用范围。三螺杆泵的流量和压力脉冲很小,噪声和振动小,有自吸能力,但螺杆加工较困难。泵有单吸式和双吸式两种结构,但单螺杆泵仅有单吸式。三螺杆泵必须配带安全阀(单螺杆泵不必配带),以防止由于某种原因如排出管堵塞使泵的出口压力超过容许值而损坏泵或原动机。

杆泵结构

三螺杆泵是利用螺杆的回转来吸排液体的。中间螺杆为主动螺杆,由原动机带动回转,两边的螺杆为从动螺杆,随主动螺杆作反向旋转。主、从动螺 杆的螺纹均为双头螺纹。

三螺杆泵是螺杆式式容积泵。在三螺矸泵中,由于主螺杆与从动螺杆上螺旋槽相互啮合及它们与衬套三孔内表面的配合,得以在泵的进口与出口之间形成数级动密封室,这些动密封室将不断把液体由泵进口轴向移动到泵出 口,并使所输送液体逐级升压。从而形成一个连续、平稳、轴向移动的压力液体。三螺杆泵所输送液体为不含固体颗粒,无腐蚀性油类及类似油的润滑性液体,粘度1.2~100oE(3.0~760cst),高粘度液体亦可通过加温降粘后输送,其温度不超过150oC。

The three-screw pump is formed by the pump body and the screw. When the active screw rotates, the driven screw that is meshed with it rotates, and the volume of the screw engaging space at the end of the suction cavity gradually increases, and the pressure decreases.

The liquid enters the meshing space volume under pressure differential. When the volume is increased to a maximum to form a sealed chamber, the liquid is continuously moved axially in one sealed chamber until one end of the chamber is exhausted. At this time, the volume of the screw engagement space at one end of the discharge chamber is gradually reduced, and the liquid is discharged. The working principle of the three-screw pump is similar to the gear pump except that the gear is replaced with a screw in the structure. The table shows the characteristics and applications of various screw pumps. The three-screw pump has small flow and pressure pulses, little noise and vibration, and self-priming capability, but screw machining is difficult. The pump has two types of single suction and double suction, but the single screw pump has only one suction type. The triple screw pump must be equipped with a safety valve (a single screw pump does not have to be equipped) to prevent the pump or the prime mover from being damaged due to some cause, such as the discharge pipe clogging, causing the outlet pressure of the pump to exceed the allowable value.

Rod pump structure

The three-screw pump uses the rotation of the screw to suck and discharge the liquid. The middle screw is the active screw, which is driven by the prime mover. The screw on both sides is the driven screw and rotates in reverse with the active screw. The threads of the main and follower screws are double-ended threads.

The triple screw pump is a screw type positive displacement pump. In the three-screw pump, due to the mutual engagement of the spiral grooves on the main screw and the driven screw and their cooperation with the inner surfaces of the three holes of the bushing, several dynamic seal chambers can be formed between the inlet and the outlet of the pump. The chamber will continue to move the liquid axially from the pump inlet to the pump outlet and step up the delivered liquid. This creates a continuous, smooth, axially moving pressure fluid. The liquid delivered by the three-screw pump is a lubricity liquid free of solid particles, non-corrosive oils, and the like. The viscosity is 1.2 to 100oE (3.0 to 760 cst). The high-viscosity liquid can also be transported by heating and viscosity reduction, and its temperature Not more than 150oC.
