随着人们生活水平的日益提高，人们对家庭生活的舒服要求也越来越高。 随之而来的是，各种电器产品在便利人类生活的同时，也占据了不小的空间。 因此，越来越多的多功能电器进入了人们的生活。 热水器也同样经历着不同世代的发展，那么，下面一起了解下增压泵的特点及用途吧!
With the continuous improvement of living standards, people have growing demands for home comfort. While various electrical appliances bring convenience to daily life, they also take up considerable space. Hence, multi-functional home appliances are increasingly popular. Water heaters have also undergone iterative upgrades. Let's take a look at the features and applications of booster pumps.
热水器水压不足，点不着。 如果设置家庭用加压泵的话，可以简单地解决这个问题，所以可以安心地洗热水澡。
Insufficient water pressure often prevents water heaters from igniting properly. Installing a household booster pump can easily solve this problem, allowing you to enjoy hot showers comfortably.
什么是加压泵?
增压泵顾名思义是用于增压的泵，主要有热水器增压用、高楼低水压、桑拿和洗澡等加压用、公寓顶层水压不足的加压用、太阳能自动增压、反渗透净水器增压用等。
增压泵的结构是什么?
首先在增压泵内注满液体，然后启动离心泵，叶轮迅速旋转，叶轮叶片使液体旋转，液体旋转时由于惯性流向叶轮的外缘，同时叶轮从吸入室吸入液体。 在这个过程中，叶轮中的液体绕着叶片旋转，在回旋运动中升力作用于液体，相反，叶片以和这个升力同样大小、方向相反的力作用于液体，这个力作用于液体，赋予液体能量，从叶轮流出
采用单一气控非平衡气体分配阀实现泵的自动往复运动，泵体的气体驱动部分采用铝合金制。 液体接触部分根据介质选择碳钢或不锈钢。 泵一般有吸气、排气两个端口，吸气端口能够产生低于常压(即大气压)的气压称为“负压”。 排气口能产生高于常压的气压的叫做“正压”; 例如人们常说的真空泵是负压泵，加压泵是正压泵。 正压泵和负压泵有很大不同。 例如，气体流动、负压泵外部气体被吸入吸嘴; 正压从排气喷嘴喷出; 例如气压的高低等。
增压泵的功能
“负压泵”、“正压泵”主要从功能和主要用途上人为区分。 “负压泵”主要用于对真空(负压)有要求的情况，如抽气、气体分析、气体循环、气体采样、真空吸附、间接吸水等。 另一方面，“正压泵”主要以泵为动力，用于移动气体、向密闭容器增压、充气、间接压水等，两者常用于医疗、科研、环境保护、仪器、控制等方面。
“负压泵”的排气侧也有正压。 但是，为微正压，远远小于“正压泵”的输出压力。 例如，微型真空泵VM、VAA、PC等系列为“负压泵”、“吸气泵”，但它们的排气侧压力经常只有几千帕。 “正压泵”的抽气端也有微负压，可以起到抽气的作用。
增压泵系列为二级加压泵，可以将低压力的气体增加到高压力，驱动气压为7bar，气体输入口的压力范围为0.5—10bar，大可以增加到90Mpa。 该系列泵的换向方式与n系列完全相同，泵整体由镁铝合金和不锈钢制造。 在泵的空气驱动部分，为了润滑密封和其他内部零件，需要使用润滑型气体。 该系列泵的驱动活塞直径为160毫米。 气体加压泵系列为单级加压泵，为了达到必要的压力，向气体输入口输入气体压力需要一定程度的预压。 预加压力因达到气体加压泵照片的大压力而异。 大可升压至80Mpa。

What Is a Booster Pump?
As the name implies, a booster pump is a device designed to increase fluid pressure. It is widely used for pressurization of water heaters, water supply in high-rise buildings, saunas and bathrooms, and water pressure improvement for top-floor apartments. It also serves for automatic pressure boosting of solar water systems and pressurization of reverse osmosis water purifiers.
Structure of Booster Pump？
First, fill the booster pump with liquid, then start the centrifugal pump. The impeller rotates rapidly, driving the liquid to spin. Due to inertia, the liquid flows toward the outer edge of the impeller, while new liquid is drawn into the impeller from the suction chamber. During operation, the liquid circulates around the blades. Lift force acts on the liquid in the rotational movement, and the blades exert an equal and opposite reaction force on the liquid. This force imparts energy to the liquid, which is then discharged out of the impeller.
A single pneumatically controlled unbalanced air distribution valve enables the pump to perform automatic reciprocating motion. The pneumatic drive section of the pump body is made of aluminum alloy, and the liquid-contacting parts are manufactured from carbon steel or stainless steel according to the conveyed medium.The pump is generally equipped with an air inlet and an air outlet. Pressure lower than atmospheric pressure at the air inlet is defined as negative pressure, while pressure higher than atmospheric pressure at the air outlet is positive pressure. For example, vacuum pumps are negative pressure pumps, and booster pumps belong to positive pressure pumps. The two types differ greatly. In terms of airflow direction, a negative pressure pump draws external air into the suction port, whereas a positive pressure pump discharges air from the exhaust port. They also vary in output pressure level.
Functions of Booster Pumps
Negative pressure pumps and positive pressure pumps are classified mainly by their functions and applications. Negative pressure pumps are used in scenarios requiring vacuum conditions, such as air extraction, gas analysis, gas circulation, gas sampling, vacuum adsorption and indirect water suction. By contrast, positive pressure pumps serve as power units for gas transmission, pressurization and inflation of sealed containers, as well as indirect water pressurization. Both types are widely applied in medical treatment, scientific research, environmental protection, instrumentation and control systems.
The exhaust side of a negative pressure pump also generates positive pressure, yet it is only slight and much lower than the output pressure of a positive pressure pump. For instance, miniature vacuum pumps of VM, VAA, PC and other series are categorized as negative pressure pumps or suction pumps, whose exhaust pressure is merely several thousand Pascals. Similarly, the suction end of a positive pressure pump produces slight negative pressure and can realize air extraction.
The booster pump series are two-stage pressure amplifiers, capable of raising low-pressure gas to high pressure. The driving air pressure is 7 bar, and the inlet gas pressure ranges from 0.5 bar to 10 bar, with a maximum output pressure up to 90 MPa. These pumps adopt the same reversing mode as the N-series and are entirely constructed from magnesium-aluminum alloy and stainless steel. Lubricated gas is required for the pneumatic drive section to maintain lubrication of seals and other internal components. The driving piston has a diameter of 160 mm.The gas booster pump series are single-stage units. To reach the rated pressure, a certain pre-pressure must be supplied at the gas inlet. The required pre-pressure varies according to the target maximum pressure, and the maximum boosting pressure can reach 80 MPa.
