Today, in the water resource industry, a water booster pump is a machine which is used to enhance and increase the pressure of a targeted fluid substance. Within the mechanism, 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 same pressure level as the output pressure to drive the piston, and a low pressure level of the power drive will use a larger diameter piston for multiplying the applied force. Under these usages, 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. Generally speaking, the water 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 substance 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 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 in the process and is normal results.
Pumps and valves are two things that are usually connected together. In the plumbing and tube sector, a valve is generally recognized as a device or natural object that regulates, directs or controls the flow of a fluid by opening, closing, or partially obstructing various passageways for the fluid substances. Normally, valves are technically fittings, but are usually discussed as a separate category due to its complicated and various applications and matched utilizations. In an open valve, fluid flows in a direction from higher pressure to lower pressure, as the physics tells it all. In the history, the simplest and ancient valve was simply a freely hinged flap which drops to obstruct fluid flow in one direction, but is pushed open by flow in the opposite direction. For this kind of valve, it is called a check valve, because it works to prevent or checks the flow in one direction. On the other hand, modern control valves may regulate pressure or flow downstream and operate on sophisticated automation systems for complex purposes.
In application, valves and pumps are two interwoven fluid control facilities that work with each other to achieve the targeted goal. A pump, by definition, is equipment that moves fluids-state substance by its mechanical action. Classically, pumps can be categorized into three major types based on the method those pumps exploited to move the target fluids. These three types are determined by the way they move fluids, and there are direct lift, displacement, and gravity methods. That is, there are direct lift pump, displacement pump, and gravity pump. Pumps are typically operated by either typically reciprocating or rotary mechanism, and consume energy to perform mechanical work moving the fluid.
