Brief introduction

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.

If the pump outlet flange fixed on the tank plane is on the plate, we code it as [x3gcg-c]. The number of outlet flanges is one or two, which we code as [x3gcg-c1] and [x3gcg-c2] respectively.

If the pump outlet flange fixed on the tank plane is on the plate, we code it as [x3gcg-g].

The pump is a bearing built-in structure, and the bearing is lubricated by the pumped liquid during the working process. According to the working condition of fluid transportation, there are several shaft seal schemes: single end face mechanical seal scheme and framework oil seal scheme.

Under the operation condition of power plant, when the pressure is lower than the rated pressure, the pump is required to start under pressure, so the manufacturing and assembly accuracy of screw must be very high.

We have also independently tested the performance of the type test device and applied for patent protection, including the operation test under the pressure start and rated operation conditions.

Series design models are divided into: x3gcg25, x3gcg36, x3gcg45, x3gcg55, x3gcg60, x3gcg70, x3gcg80, x3gcg85, x3gcg90, x3gcg100. Arabic numerals represent the outside diameter of the main rod spiral section.

Three screw pumps of the same model can change the different requirements of conveying flow by changing the screw angle, such as 36, 38, 40, 42, 44, 46, 50, 52, 54 degrees.



More economical - very low life cycle cost

Reliability - high hardness nitriding steel for screw
