三螺桿泵（原裝廠家）
三螺桿泵是依靠泵體與螺桿所形成，當(dāng)主動螺桿轉(zhuǎn)動時，帶動與其嚙合的從動螺桿一起轉(zhuǎn)動，吸入腔一端的螺桿嚙合空間容積逐漸增大，壓力降低。
液體在壓差作用下進(jìn)入嚙合空間容積。當(dāng)容積增至*而形成一個密封腔時，液體就在一個個密封腔內(nèi)連續(xù)地沿軸向移動，直至排出腔一端。這時排出腔一端的螺桿嚙合空間容積逐漸縮小，而將液體排出。三螺桿泵的工作原理與齒輪泵相似，只是在結(jié)構(gòu)上用螺桿取代了齒輪。表為各種螺桿泵的特點(diǎn)和應(yīng)用范圍。三螺桿泵的流量和壓力脈沖很小，噪聲和振動小，有自吸能力，但螺桿加工較困難。泵有單吸式和雙吸式兩種結(jié)構(gòu),但單螺桿泵僅有單吸式。三螺桿泵必須配帶安全閥(單螺桿泵不必配帶），以防止由于某種原因如排出管堵塞使泵的出口壓力超過容許值而損壞泵或原動機(jī)。
桿泵結(jié)構(gòu)
三螺桿泵是利用螺桿的回轉(zhuǎn)來吸排液體的。中間螺桿為主動螺桿，由原動機(jī)帶動回轉(zhuǎn)，兩邊的螺桿為從動螺桿，隨主動螺桿作反向旋轉(zhuǎn)。主、從動螺 桿的螺紋均為雙頭螺紋。
三螺桿泵是螺桿式式容積泵。在三螺矸泵中，由于主螺桿與從動螺桿上螺旋槽相互嚙合及它們與襯套三孔內(nèi)表面的配合，得以在泵的與出口之間形成數(shù)級動密封室，這些動密封室將不斷把液體由泵軸向移動到泵出 口，并使所輸送液體逐級升壓。從而形成一個連續(xù)、平穩(wěn)、軸向移動的壓力液體。三螺桿泵所輸送液體為不含固體顆粒，無腐蝕性油類及類似油的潤滑性液體，粘度1.2~100oE(3.0~760cst)，高粘度液體亦可通過加溫降粘后輸送，其溫度不超過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.
