三螺桿泵概述:
三螺桿泵作為液體的動力源，已廣泛安裝配套在潤滑站，液壓系統以及工藝冷卻系統中，服務于船舶、冶金、鋼鐵、石化、電力、機械加工等工業領域。多年的應用經驗證明：三螺桿泵在經濟效益、傳送質量、運轉壽命、維護保養等多方面都比其它容積式泵具有明顯的優點，已成為這些行業可以選擇配套泵浦。
盡管螺桿處于旋轉狀態，但密閉腔中的液體并不發生攪拌或渦流，只以低速沿主桿軸向平移，因此三螺桿泵具有優異的吸入性能。
主桿完全處于液壓平衡狀態，從桿由液壓驅動。主、從桿之間在正常運行工況下不接觸。由于油膜的存在，螺桿螺旋面不會產生磨損，使得三螺桿泵具有很長的使用壽命。需要說明的是，當開泵、停泵時，泵內主、從桿處于邊界狀態，瞬間會發生直接接觸，螺桿強度、表面硬度、加工精度必須能夠抵抗這種邊界狀態工況。另外，從桿要承受一定的徑向力，這是理論決定的。只有在螺桿、襯套、材料選用與使用壓力的適用性方面合理匹配，才能**從桿外圓與襯套內孔之間的油膜不發生破損，從而避免金屬接觸而磨損。對于潤滑油輸送泵，我公司有成熟的技術和可靠的工藝手段避免以上事故的發生。
工作原理、結構、特性
三螺桿泵屬于回轉式容積式泵，其泵送原理為：一個泵體（或三孔襯套）和對稱平行布置的三根相互嚙合的螺桿精確配合形成連續的相互隔離的密閉腔，當主桿轉動時，流體被吸入到密閉腔中，隨著主桿轉動密閉腔連續、均勻地沿軸向移動，從而帶動流體由泵進口腔排送至出口腔，實現泵送升壓過程。
三螺桿泵適用于輸送各類不含磨蝕性雜質且對泵內零件不發生化學侵蝕的潤滑性液體。例如：潤滑油，礦物油，合成液壓油和天然油，其它比較特殊的潤滑性介質如輕質燃油，重質燃油，煤焦油，高溫瀝青，粘膠液，乳化液等也可使用三螺桿泵進行輸送。此時，務必參閱相應的產品樣本，進行正確選型和使用。
The performance parameter and reliability of three screw pumps depend a greatly extent on the machining accuracy of manufacturing devices. CTP have got leading manufacturing level of the whole industry in china and advanced machining methods. The company have bought more than 20 sets of advanced machines abroad, such as screw rotor CNC grinding machine and high-accuracy screw three-dimensional testing instrument from Germany, which represent advanced machining lever of screw rotor, high efficient and high-accuracy screw machining milling machine and machining and detecting machines for screw milling cutter from Britain, high-accuracy inner-rotor CNC milling machine for lengthening screw from Austria, optic projector from Italy, machining center capable of various complicated technical process from Germany and Italy, universal tool microscope and measuring machine from Japan, deep hole drilling machine from Germany, large-size CNC turning machining center from Germany etc. Besides, there are also high-accuracy coordinate boring machine, optics curve grinding machine, large-size planer-type milling machine etc. CTP’s powerful machining capability in screw rotor can’t be matched by any other screw-pump manufacturers in China. And its machining capability and machining accuracy also have reached international advanced level. Currently CTP have got the ability to machining various screw rotors with different screw lines, whose diameter rang from 10~630mm and length rang from 90~6000mm.

Three screw pumps can be used in the transformation of any lubricating liquid without any caustic impurity and the liquid that not chemically erode the component of the pumps. For example,   lubricating oil, mineral oil, synthetic hydraulic fluid and natural oil can be transferred by them. And other special lubricating medium such as light fuel, reduced fuel oil, coal oil, high-temperature pitch, viscose and emulsion can also be transferred by three screw pumps. But now you should read the corresponding product manual, select a right pump and used it.
INTRODUCTION FO THREE SCREW PUMPS 
Three screw pumps are widely used in lubrication stations, hydraulic systems and process cooling systems as power source of liquid, service for industry field of shipbuilding, metallurgy, iron and steel, petrochemical industry, power, machining, etc. Our experience in these years show that three screw pumps are more excellent than other pumps in the sides of economic benefit, transfer quality, running life and maintenance，it has been become the best choice of pump in the field we have mentioned above.
OPERATING PRINCIPLE, STRUCTURE ANDCHARACTERISTIC OF THREE SCREW PUMP
Three screw pump is a kind of rotary displacement pump. Its operating principle could be described as follows: Consecutive separate hermetic spaces are formed by accurately fit of a pump casing and three parallel screws in mesh. When driving screw rotates, medium is absorbed into the hermetic spaces. The hermetic spaces make an axial movement continuously and equably as the driving screw moves. In this way, fluid is carried from suction side to delivery side, and the pressure is lift in the whole process.
Although the screws are rotating, fluid in the hermetic spaces doesn’t mix round or form vortex, but slowly makes an axial movement follows the direction of driving screw, which makes three screw pumps have excellent capability of absorption.
Driving screw is hydraulic balanced, and driven screws are driven by hydraulic pressure. The driving screw and the driven screws never touch each other in normal working condition. Oil film is formed between them, so the helical surface of screws doesn’t wear down with the movement, that provide three screw pumps a long life-span. But it has to be pointed out that driving screw and driven screws are in critical state and touched directly when the pumps are started up or shut down. So the intensity, surface hardness and machining accuracy of screws must be suit for the critical state. Furthermore, driven screws have to suffer some kind of radial force. As a result, screws, insert, materials and pressure in use must be perfectly matched to insure the oil film between outer round of screw and inner bore of bushing not to be worn out and avoid the abrasion of metal surface. With regard to lubricating oil transfer pumps, CTP has mastered mature technique and reliable technical methods to avoid the defects mentioned above.
It is necessary for users to provide required data and information required by the “data & information needed for selecting pumps” when pumps are selected.
