I have a question regarding small-flow specialty pumps; I hope experts can provide some guidance
Thread Content
For small-flow specialty pumps as well, why do some have auxiliary oil pumps while others don’t? What is the difference? Are there any relevant materials you can share?
There’s no one else; I’ll take on the task by myself. Please, experienced colleagues, could you give me some advice?
Those with an oil pump use forced lubrication, while those without it use splash lubrication. If it’s a Tiande model, you can check the nameplate: GSB-F uses splash lubrication, while GSB-Q uses forced lubrication. You can ask the manufacturer; we don’t produce this type of pump, so I’m not very familiar with it either.
Okay, thank you, moderator. I’ll check the nameplate tomorrow! !
Splashing lubrication is the same as the lubrication method used in ordinary mechanical pumps, right?
Does the moderator have a schematic diagram of this pump’s structure? Is it just that it has an additional gearbox compared to a regular centrifugal pump?
Ordinary pumps generally use lubrication methods such as oil baths, slinger rings, and oil splash plates, while the splash lubrication mechanism of high-speed pumps should differ to some extent from that of ordinary centrifugal pumps. Take a look at the pump’s cross-section diagram.
I really don’t have any cross-sectional views; this type of pump has an inducer wheel at its inlet, the impeller features open straight blades, and its sealing mechanism is different from that of ordinary centrifugal pumps.
Thank you to the moderator for your patient answers; I’ll take another look! !
I forgot to ask yesterday: are these low-flow specialty pumps considered high-speed pumps? Moderator, I think the rotation speed is similar to that of ordinary centrifugal pumps
It’s a high-speed pump, with speed-increasing gears inside
