Is a rotor pump suitable for unloading diesel?
Thread Content
From general information, it is known that rotor pumps are more suitable for oils with higher viscosity. The rotor pump was chosen as the unloading pump for diesel, to draw oil from railway tank cars at a height of 2.8–3.5 m above the pump’s foundation surface. In actual use, the rotor pump experienced significant vibration and produced considerable noise; what is the reason for this? When starting the pump, open the inlet valve fully and open the outlet valve to 1/3 of its capacity; once the outlet pressure stabilizes, gradually increase the opening degree. The diameters of both the inlet and outlet pipes are 200.
I have never seen this situation; most rotor pumps I have seen are used in sucrose production plants, where the viscosity is high.
Why not use a sliding vane pump? ? The original poster should take a look; I think it can achieve the results you’re satisfied with
We use screw pumps for unloading (for coal tar, VGO, etc.), and aside from the inlet filters often getting clogged, there are few other problems.
For transporting diesel, kerosene, and other light oils, it is recommended to use self-priming centrifugal pumps. These pumps operate smoothly with no noise, offer high flow rates, and possess explosion-proof properties. The rotation of the impeller involves no collisions between metals, thereby reducing risks. Their price is also more affordable compared to rotary pumps or screw pumps
