风囊泵工作原理

　　风囊泵的工作原理是基于气动原理进行工作的，也称为气动隔膜泵。其详细工作原理可以归纳如下：

一、基本构成

　　风囊泵主要由泵体、隔膜、换向阀、进排气口以及液相和气相工作腔等部分组成。其中，隔膜将泵腔分为两个工作腔：气相工作腔和液相工作腔。

二、工作步骤

　　气动驱动：

　　当压缩空气或其他气体通过气动驱动装置(如气动阀)输入到泵的一个隔膜背面时，气压会使隔膜向前移动。这个过程中，气体进入气相工作腔，推动隔膜变形。

　　吸入阶段：

　　随着隔膜的前进，泵腔内的压力降低，形成一个低压区域。这个低压区域使得液体从进口处被吸入到泵腔的液相工作腔中。

　　排出阶段：

　　当气动驱动装置改变状态，使气体输入到隔膜的另一侧时，隔膜会向后移动。这个过程中，泵腔内的压力增加，推动液体从液相工作腔中排出，并通过出口输送到需要的位置。

　　压力平衡与循环：

　　当液体被排出后，隔膜再次向前移动，并在进口处形成新的负压区域，使得新的液体再次被吸入。这个过程通过换向阀的控制，使压缩空气依次进入两个气相工作腔工作，从而实现液体的连续输送。

三、特点与优势

　　无需电源：风囊泵不需要电源，接入气管，气动驱动，使其具有节能、环保的优点。

　　无金属污染：风囊泵泵体采用高纯PTFE,不会对纯水或者化学药液产生任何金属污染。

　　高可靠性：风囊泵的独特密封结构使其具有较高的可靠性，能够防止化学药液的泄露。

　　适用范围广：风囊泵可用于输送电子级纯水、酸、碱，最高温度达210°适用范围广。

　　操作方便：风囊泵的操作方式简单，只需要通过简单的控制压缩空气通断就可实现泵的控制。

　　使用寿命长：圆弧风囊由PTFE制作而成，无摩擦，大大延长了使用寿命。

　　维护简单方便：泵体结构简洁明快，故障率低。

　　综上所述，风囊泵通过压缩空气或气体的驱动，实现隔膜在泵腔中的往复运动，从而完成对液体的吸入、输送和排出。这种工作原理使得风囊泵在多个领域具有广泛的应用价值。

　　The working principle of the air bladder pump is based on the pneumatic principle to work, also known as pneumatic diaphragm pump. Its detailed working principle can be summarized as follows:

　　First, the basic composition

　　The air bladder pump is mainly composed of pump body, diaphragm, reversing valve, inlet and exhaust port, and liquid phase and gas phase working chamber and other parts. Among them, the diaphragm divides the pump chamber into two working chambers: the gas-phase working chamber and the liquid-phase working chamber.

　　Second, the working steps

　　Pneumatic drive:

　　When compressed air or other gases are fed into the back of one of the pump's diaphragms through a pneumatic drive (e.g., a pneumatic valve), the air pressure causes the diaphragm to move forward. In this process, the gas enters the gas phase working chamber and pushes the diaphragm to deform.

　　Suction phase:

　　As the diaphragm advances, the pressure in the pump chamber decreases, creating a low-pressure region. This low-pressure area allows the liquid to be drawn from the inlet into the liquid-phase working chamber of the pump chamber.

　　Discharge phase:

　　The diaphragm moves backward when the pneumatic drive changes state so that gas is fed to the other side of the diaphragm. This process increases the pressure in the pump chamber, pushing the liquid out of the liquid phase working chamber and conveying it through the outlet to the desired location.

　　Pressure Equalization and Circulation:

　　When the liquid is discharged, the diaphragm moves forward again and creates a new area of negative pressure at the inlet, allowing new liquid to be drawn in again. This process is controlled by the reversing valve, so that the compressed air enters the two gas-phase working chambers in turn to work, thus realizing the continuous conveying of liquid.

　　Features and advantages

　　No power supply: the air bladder pump does not require power, access to the air pipe, pneumatic drive, so that it has the advantages of energy saving, environmental protection.

　　No metal pollution: wind bladder pump pump body using high purity PTFE, will not produce any metal pollution of pure water or chemical liquid.

　　High reliability: the unique sealing structure of the air bladder pump makes it highly reliable and prevents the leakage of chemical liquid.

　　Wide range of application: the air bladder pump can be used to transport electronic grade pure water, acid, alkali, the highest temperature up to 210 ° wide range of application.

　　Easy to operate: the operation of the airbag pump is simple, only through a simple control of the compressed air on and off to realize the control of the pump.

　　Long service life: the arc airbag is made of PTFE, frictionless, greatly extending the service life.

　　Simple and convenient maintenance: the pump body structure is simple and clear, low failure rate.

　　In summary, the wind bladder pump is driven by compressed air or gas to realize the reciprocating motion of the diaphragm in the pump cavity, so as to complete the suction, conveying and discharging of the liquid. This working principle makes the airbag pump has a wide range of application value in many fields.
