In the refinery I work in they used a gear pump to pump a slurry of solvent, water and perlite powder (finely crushed volcanic glass). As you can imagine it needed extremely frequent maintenance, the perlite was literally sanding down everything inside the pump. Why they decided to use a gear pump for this slurry in the first place is beyond me, but they finally put in a better suited pump.

Indeed, while attempting a Christopher Walken impersonation

Internal gear pumps are pretty much standard for automotive engine oil distribution. One of the advantages they have (in that application) is that they have no bearings. The inner gear will sit on the front end of the crankshaft, which has its own bearings. The outer gear will free float inside the oil pump housing. The engine oil being moved by the oil pump lubricates everything.

@hydraulicandpneumaticsyste3253

2 жыл бұрын

@protoborg

Жыл бұрын

Nope. Oil is distributed across the gears by immersing one of the gears in the oil directly. It is NOT moved by a pump. It is moved around the parts by capillary action between the gears. In other words, the oil is passed from one gear to the next by the fact that it sticks to the gears. When the gear interfaces with the next gear, the contact causes some of the oil to transfer to the other gear.

@AlexandarHullRichter

@@protoborg you might have misread. You're describing the lubrication of a manual transmission. I was talking about the engine, which only has gears in the oil pump and camshaft timing mechanism. Engines are lubricated by pressurized oil from the pump.

The animation is correct. It is necessary to correctly understand how the liquid moves in the pump. She moves around the perimeter. Through the place where the teeth of the gears are engaged, the liquid cannot flow, so there is no empty volume. I want to release a short video where this issue will be discussed in more detail.

Nice explanation, I always thought they worked the other way around. What I am wondering is: Do the liquids get smashed around and get bubbly and foamy on the output side? Because the moving direction of the gears is exactly opposite to the direction of liquid flow.

@hydraulicandpneumaticsyste3253

Жыл бұрын

The fluid does not flow through the engagement, there is no free volume. Fluid flows around the perimeter. At the moment when the teeth disengage, the volume of the working chamber increases, the liquid from the suction line fills the space between the teeth. Then the gear turns and the liquid is locked in the space between the teeth and the housing. Then the teeth engage and the liquid is squeezed out of the volume between the teeth, it flows into the pressure line.

@MrHaggyy

9 ай бұрын

depends on the viscosity and RPM of the pump. With the right pump, most liquid is pushed away from the teeth and barely moves back to the input. If the viscosity and rpm of the pump are too high the liquid can`t escape that easily and will get compressed by the gearing. This can cause bubbles and foam as we have different pressures and velocities within the fluid.
