    三螺杆泵概述:
    三螺杆泵作为液体的动力源，已广泛安装配套在润滑站，液压系统以及工艺冷却系统中，服务于船舶、冶金、钢铁、石化、电力、机械加工等工业领域。多年的应用经验证明：三螺杆泵在经济效益、传送质量、运转寿命、维护保养等多方面都比其它容积式泵具有明显的优点，已成为这些行业可以选择配套泵浦。
    尽管螺杆处于旋转状态，但密闭腔中的液体并不发生搅拌或涡流，只以低速沿主杆轴向平移，因此三螺杆泵具有优异的吸入性能。
    主杆完全处于液压平衡状态，从杆由液压驱动。主、从杆之间在正常运行工况下不接触。由于油膜的存在，螺杆螺旋面不会产生磨损，使得三螺杆泵具有很长的使用寿命。需要说明的是，当开泵、停泵时，泵内主、从杆处于边界状态，瞬间会发生直接接触，螺杆强度、表面硬度、加工精度必须能够抵抗这种边界状态工况。另外，从杆要承受一定的径向力，这是理论决定的。只有在螺杆、衬套、材料选用与使用压力的适用性方面合理匹配，才能保证从杆外圆与衬套内孔之间的油膜不发生破损，从而避免金属接触而磨损。对于润滑油输送泵，我公司有成熟的技术和可靠的工艺手段避免以上事故的发生。
    工作原理、结构、特性
    三螺杆泵属于回转式容积式泵，其泵送原理为：一个泵体（或三孔衬套）和对称平行布置的三根相互啮合的螺杆精确配合形成连续的相互隔离的密闭腔，当主杆转动时，流体被吸入到密闭腔中，随着主杆转动密闭腔连续、均匀地沿轴向移动，从而带动流体由泵进口腔排送至出口腔，实现泵送升压过程。
    三螺杆泵适用于输送各类不含磨蚀性杂质且对泵内零件不发生化学侵蚀的润滑性液体。例如：润滑油，矿物油，合成液压油和**油，其它比较特殊的润滑性介质如轻质燃油，重质燃油，煤焦油，高温沥青，粘胶液，乳化液等也可使用三螺杆泵进行输送。此时，务必参阅相应的产品样本，进行正确选型和使用。
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.
