Three screw pump is an important kind of non abrasive oil-based fluid transmission equipment with certain lubricity. Because of its stable flow, small pressure fluctuation, high cost performance, and no shear transmission of medium with low viscosity, it is widely used in various industrial processes, also known as the positive displacement three screw pump, three blade rotor pump and three-axis transmission pump.
Xinglong three-screw pump is a positive displacement pump, which transmits liquid through a cavity with a certain geometry formed by sealing between the meshing pairs (main and subordinate rods and bushes). The main components of the pump include three rotating screws and a three hole bush wrapped around its outer circle contour. The driving screw is driven by the driving machine to rotate. The two driven screws are driven by the liquid film between the main rod and the driving screw to rotate passively. The driving screw and the driven screw are both working in the closely matched Bush hole. Therefore, between the pump inlet and the outlet, the screw and the bush are separated by a certain number of bolts and bushes What is the shape of the conveying cavity. These closed cavities form a step-by-step boost pumping process from the pump inlet to the outlet as the screw rotates.
Double layer heat preservation three screw pump is suitable for all kinds of non corrosive oil and similar oil and lubricating liquid. The viscosity range of the liquid is generally 3.0-760 CST. The high viscosity medium can be pumped after heating, and the temperature limit temperature is 350 ℃.
The jacket can be filled with steam, hot water and heat-transfer oil, so that the pump body can operate at a controllable temperature, and the internal fluid will not agglomerate and damage the pump components. According to the temperature and characteristics of the fluid, we use several combinations of machinery and bearings. E6.7 the scheme adopts single face mechanical seal and bearing external structure, because the bearing cannot be lubricated by fluid or the upper limit of fluid temperature is 150 ℃. E15 scheme adopts metal bellows mechanical seal and bearing external structure, because the bearing cannot be lubricated by fluid or the fluid limit temperature is 350 ℃.
More economical - very low life cycle cost
Reliability - high hardness nitriding steel for screw
Non pulsating delivery - the medium is stable and non pulsating during pumping
Easy to maintain - when replacing major parts (including screws and bushings), the pipeline does not need to be removed
Flexibility - low inlet pressure and wide allowable speed range
Low noise - working principle virtually eliminates pressure fluctuations
Self absorption - normally no forced feeding device or equipment is required
