If you are a mechanical engineer, you probably have at least a passing knowledge of hydraulic pumps practies. They use pressure to create motion in machines and processes. But, they also have a few disadvantages. Let’s examine them. Compared to electric motors, hydraulic pumps weigh less and produce more torque. Both of these types of pumps create pressure by spinning and drawing fluid. So, which is better? Which is more efficient, and which is more expensive?
Another disadvantage of hydraulic pumps is their limited production range lovoo. The range depends on the number of stages. This means that it is difficult to change production rates without changing pumps or a variable-speed surface drive. Another disadvantage of hydraulic pumps is their need for downhole gas separators when producing high-GOR fluids. And, they have to be replaced or repaired in the well, which requires the removal of tubing edunewszone. In the end, the advantages of hydraulic pumps far outweigh their drawbacks.
The most versatile type of hydraulic pump is the piston pump newspedias. They are highly efficient and offer options for any system. Piston pumps can operate at pressures of up to 6000 psi. Piston pumps are quiet and tend to resist wear better than other pumps. Piston pumps can operate in a variety of fluid viscosities, ranging from ten to 160 cSt. They are often used for low production volumes, and onshore oil drilling operations newsinsightz.
