Hydraulic pump as a brake
Hydraulic pump as a brake
(OP)
Hello Gents,
I would like to build a test station that simulate a load acting an an auger (auger for drilling holes in a soil).
The test station will be build of an auger with a motor and system that simulate a load coming from a resistance when an auger drill into soil.
My first idea was to mount at the end of the auger shaft a hydraulic pump. A pump will charge a shaft with a constant increasing load (as in real: when auger go deeper into soil then shaft is more loaded).
What do you think about the idea?
What kind of hydraulic pump do you recommend to use?
What about other hydraulic components in hydraulic system, relieve valves etc.?
Thank you in advance.

If you don't use it, then it will turn into heat that you have to get rid of.
How much energy are your expecting to have to dissipate?
Whether you use some break resistors, or a pump with a relief valve, the unused energy will turn into heat.
Pump wise, you can use any...gear, vane or piston, even centrifugal.
How much energy (power) are you expecting to get out of the auger?

See http://www.islandcomponents.com/Precision-Brakes.a... for typical options which are probably more controllable, cheaper and don't have issues with temperature rise, pipes, cooling control valves etc

Also: If you get a response it's polite to respond to it.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
RE: Hydraulic pump as a brake
Everything you have said is true but the question was about hydraulics.
I don't have specialist knowledge in the area but in a general sense i can't see why it can't be made to work.Energy dissipation will obviously be a major issue.

And NO a large reservoir will not control temperature. Just in case somebody would ask.

Yes, I can build a hydraulic system with cooler.
I will start the investigation with hydraulic system. Electrical system will be suspend at this time.

What drives the auger? You could use one of those....

I presume that you will measure torque with a cell, and speed.
The motor (being used as a pump), a tank, control valve, and heat exchanger and you should be set.
