In the automation industry, water control phase is involved as well for the reason that automatically controlled pumps are more or less helpful for the overall automation consideration. In the water resource industry, an automatic booster pump is a machine which is utilized to enhance and increase the pressure of a targeted fluid substance for specific purposes. This type of booster pumps may be deployed with liquids or gases, but the construction details will vary case by case based on the fluid types and the corresponding substance characteristics.
As the industry protocol progresses, those powered by compressed air are usually linear actuated systems, in which a pneumatic cylinder directly drives the compression piston, often in a common housing, which is separated by a seal unit. Moreover, a high pressure pneumatic drive arrangement may use the identical pressure as the output pressure to drive the piston, and a low pressure drive will use a larger diameter piston for multiplying the applied force. For its utilization case, they are mostly applied for water heater pressurization, high-rise low water pressure, sauna, bathing and other pressurization, insufficient pressure at the top of the apartment, solar automatic pressure increase, reverse osmosis water purifier pressure increase, and many other commercial usages.
That is to say, generally speaking, the booster pump is filled with liquid first, and then the centrifugal pump is started then. Later, the impeller rotates rapidly, and the impeller's blades drive the liquid to rotate for sure. After that, when the liquid rotates, it flows to the outer edge of the impeller by inertia as normal physical effects. In the impeller side, the liquid flows around the blades, and the liquid acts on the blades in the flow. In turn, the blades act onto the liquid with a force equal to this lifting force, and then in the opposite direction. This is a basic explanation.
The force does work on the liquid and makes the liquid obtain whenever the energy flows out of the impeller. The kinetic energy and pressure energy of the liquid increase during the process and are normal results. The working principle of gas-liquid booster pump is similar to that of a pressure booster. It applies a very low pressure to a large-diameter air-driven piston first. When this pressure acts on a small area piston, a high pressure is generated then. Through a two-position five-way air-controlled reversing valve, the booster pump can achieve continuous operation as anticipated. The high-pressure plunger controlled by the check valve continuously discharges the liquid, and the pressure at the outlet of the booster pump is related to the air driving pressure.
To tht end, when the pressure between the driving part and the output liquid part reaches equilibrium state, the booster pump will stop running and no longer consume the air. When the output pressure drops or the air-driven pressure increases, the booster pump will automatically start running until it stops automatically after reaching pressure equilibrium again. A single gas-controlled unbalanced gas distribution valve is used to realize the automatic reciprocating motion of the pump, and the gas drive part of the pump body is made of aluminum alloy. With the automatic controller to be equipped, automatic booster pumps are thus able to control the liquid substance in a much more controllable manner.
