增压泵安装在管路增压泵上，是多种泵的特殊名称。一般称管路增压泵，是指安装在管道上的泵，不限于指某种类型或形式的泵，可以是立式或卧式，如立式多级离心泵、立式多级离心泵、立式单级离心泵、卧式单级离心泵、自吸离心泵，可称为管路增压泵。一般行业称管式增压泵，一般指管式结构泵，可直接安装成管式泵。
A pipeline booster pump is a general term for various pumps installed on piping systems. It is not limited to a specific type or structure, and can be vertical or horizontal. Typical examples include vertical multi-stage centrifugal pumps, vertical single-stage centrifugal pumps, horizontal single-stage centrifugal pumps and self-priming centrifugal pumps.
In the industry, inline booster pumps specifically refer to pumps with inline structure, which can be directly mounted onto pipelines.
由于增压泵属于泵的另一个名称，所以他的选择同样符合离心泵的选择，注意的参数只不过是流量、物料、介质比重等。 泵的流量和扬程通常是指泵的额定流量和额定扬程，所谓的额定流量和额定扬程是指泵的进出口全开，以工频(50Hz)工作的情况。 泵泵送的水量和泵可泵送的高度。 与额定扬程相对应的泵的额定流量称为泵的最佳工作点。 该工作点是泵最有效的工作点，因此，在选择泵时选择泵的最佳参数，不仅可以发挥泵的最佳潜力，而且可以提高泵的使用寿命。
Since booster pump is a general name for pump categories, its selection criteria are the same as those for centrifugal pumps. Key parameters to consider include flow rate, conveyed medium and medium specific gravity.
The flow rate and head of a pump generally refer to the rated flow rate and rated head. They are defined as the operating parameters when the pump inlet and outlet are fully open under power frequency (50Hz). Flow rate indicates the water delivery volume, while head represents the maximum delivery height.
The rated flow rate corresponding to the rated head is known as the best operating point of the pump. This point delivers the highest operating efficiency. Selecting pumps based on optimal parameters can maximize performance and extend service life.
增压泵的工作原理是怎样?
将首先充满液体增压泵,然后启动离心泵,叶轮高速旋转,叶轮叶片驱动液体,液体依靠旋转惯性的流叶轮外缘,同时从吸入腔叶轮吸入液体,在这个过程中,流体在叶轮叶片内流动时，在流体绕流时对叶片产生升力，反之，叶片对液体施加的力与升力相等且相反。这个力作用在液体上，使液体获得能量并流出叶轮。此时液体的动能和压力能都增加了。
Working Principle of Booster Pumps
First, fill the booster pump with liquid, then start the centrifugal pump. The impeller rotates at high speed, and its blades drive the liquid. Driven by rotational inertia, the liquid flows toward the impeller rim, while new liquid is continuously drawn in from the suction chamber.As fluid flows along the impeller blades, lift force acts on the blades during flow around them. In reaction, the blades exert an equal and opposite force on the liquid. This force imparts energy to the liquid, which then exits the impeller with increased kinetic energy and pressure energy.
气液增压泵的工作原理类似于增压泵，它对大直径气动活塞施加很低的压力，当这个压力作用在小面积活塞上时，就产生了很高的压力。增压泵通过两位五气控换向阀，可以实现连续运行。单向阀控制的高压柱塞不断排出液体，增压泵出口压力与空气驱动压力有关。当驱动部分和输出液体部分之间的压力平衡时，增压泵将停止运行，不再消耗空气。当输出压力下降或空气驱动压力增加时，增压泵将自动开始运行，直到再次达到压力平衡，并自动停止。采用单个气动控制不平衡配气阀门实现泵的自动往复运动，泵体气动驱动部分采用铝合金材质。液体接收部分根据不同的介质由碳钢或不锈钢制成。通常，泵有两个端口:进气口和出气口。进气口处产生的气压低于正常气压(即大气压)的气压称为“负压”。它被称为“正压”，可以在排气口产生高于正常压力的空气压力;比如真空泵是负压泵，增压泵是正压泵。正压泵与负压泵有很大的不同。比如气流方向，负压泵是指外部气体被吸入吸嘴;正压从排气喷嘴喷出;比如气压水平。
Working Principle of Pneumatic Hydraulic Booster Pump.The working principle of pneumatic hydraulic booster pumps is similar to ordinary booster pumps. Low air pressure acts on the large-diameter pneumatic piston, and this pressure applied to the small-area piston generates extremely high output pressure.Equipped with a two-position five-way pneumatic directional valve, the pump can operate continuously. The high-pressure plunger controlled by check valves discharges liquid steadily. The outlet pressure of the pump is correlated with the driving air pressure. The pump stops automatically and consumes no compressed air once pressure balance is achieved between the driving section and liquid output section. It restarts automatically when the output pressure drops or the driving air pressure rises, and shuts down again upon re-establishing pressure balance.
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, while the liquid chamber is manufactured from carbon steel or stainless steel according to different conveyed media.The pump is generally fitted 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 instance, vacuum pumps belong to negative pressure pumps, and booster pumps are positive pressure pumps.There are distinct differences between positive pressure pumps and negative pressure pumps. 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 differ greatly in pressure level.
