Mining Pumps and Their Functions Quiz

The removal of excess water from mining operations, often using pumps.

A mixture of water and solid particles used in mineral processing.

A fluid used in hydraulic machines to exert force.

The major challenge in mining, involving collecting and removing water from the mine site.

A detailed study of the underground water conditions in a potential mining area.

The preferred medium for grinding, classification, and enrichment in mineral processing.

A mixture of water and solid particles, used for transporting minerals in processing plants.

Processing wastes that are often pumped into tailings dams or used as fill material.

Machines designed to move fluids from one place to another or to elevate them to a higher level.

An ancient pump, invented by Archimedes, that uses a rotating spiral to transport fluids uphill.

These utilize natural height differences and water pressure to elevate fluids.

A positive displacement pump where a piston moves within a cylinder to create suction and discharge.

Pumps that use mechanical displacement to move fluids. They typically move smaller volumes with high pressure.

They use a spinning impeller to create centrifugal force, which moves fluids outwards and creates pressure.

Use a spinning rotor with screw-shaped blades to move fluids.

Machines that compress and move gases, often used to increase their pressure.

A type of pump that moves a fixed volume of liquid with each cycle, maintaining consistent flow regardless of pressure resistance.

A pump incorporating a piston moving back and forth to displace liquid. Known for high output pressure, suitable for high viscosity fluids.

A pump consisting of two gears rotating in opposite directions, transferring liquid from one side to the other. Used for viscous liquids and hydraulic oils.

A type of pump featuring a spiral blade rotor that rotates at a low speed. Designed for high flow rates with minimal energy input.

The most common type of pump, using centrifugal force to move liquids outward, creating a continuous flow. Ideal for low viscosity fluids.

A type of positive displacement pump that operates with a piston transferring liquid from one chamber to another. They can reach extremely high pressure levels.

The ability of a liquid to resist flow, making it 'thick' or 'sticky'.

The characteristic of a pump to deliver a pulsed or intermittent flow of liquid, unlike a continuous flow.

The speed at which the pump shaft rotates, directly influencing the volume of water pumped.

The relationship between the diameters of two pulleys connected by a belt and their rotation speeds. The product of the pulley diameter and rotation speed remains constant between the two pulleys in a system.

The rate at which a pump can move water is proportional to the pump shaft speed. A faster shaft pumps more water.

An increase in the speed of a pump shaft or engine will result in a greater volume of water being pumped. Conversely, a decrease in speed will reduce the amount of water pumped.

The safety factor is a percentage added to the required power of a pump to account for factors like potential wear and tear, variations in operating conditions, and unforeseen circumstances.

The diameter of the inlet and outlet pipes of a centrifugal pump. For example, an 8/6 pump has an 8-inch inlet and a 6-inch outlet.

The section of the centrifugal pump where the fluid enters.

The section of the centrifugal pump where the fluid exits.

A component in the centrifugal pump that spins and transfers energy to the fluid, creating pressure.

The formula used to calculate the power required for a centrifugal pump, taking into account flow rate, head, slurry density, and efficiency.

The percentage of energy input that is converted into useful work by the pump. Higher efficiency means less energy wasted.

The additional power needed for a centrifugal pump when it's used to pressurize a liquid, like forcing it into a cyclone.

A graph that shows the relationship between a pump's flow rate, head, and efficiency at different operating conditions.
