The diaphragm seal of the metering pump is an important component in the metering pump, mainly used to seal the interface between the metering pump diaphragm and the pump casing. Qisheng New Materials tells you to ensure the accuracy and stability of the metering pump.

Generally speaking, the diaphragm seal of a metering pump needs to have the following performance aspects:

1. Corrosion resistance: The diaphragm seal of the metering pump needs to be able to withstand the corrosion of various chemical media to ensure the service life and stability of the metering pump. Generally speaking, fluororubber seals have excellent corrosion resistance and are suitable for transporting chemical media such as strong acids and alkalis.
2. Wear resistance: The diaphragm seal of the metering pump needs to be able to withstand the friction and impact of the fluid to ensure the flow rate and accuracy of the metering pump. The nitrile rubber seal has excellent wear resistance and is suitable for conveying abrasive media, such as in the petrochemical industry.
3. High temperature resistance: The diaphragm seal of the metering pump needs to be able to withstand working in high temperature environments to ensure the stability and accuracy of the metering pump. Silicone rubber seals have excellent high-temperature resistance and are suitable for metering pumps in high-temperature environments.
4. Elasticity and sealing performance: The diaphragm seal of the metering pump needs to have a certain degree of elasticity to ensure the flow rate and accuracy of the metering pump. At the same time, the surface treatment and installation method of the seal also have an impact on the sealing performance. For example, lubrication treatment on the surface of sealing components can reduce friction coefficient and improve sealing performance; The correct installation method can avoid damage and leakage of the seals.

When selecting diaphragm seals for metering pumps, it is necessary to choose the appropriate seal according to the specific working environment and requirements. Usually, it is necessary to consider factors such as the material, shape, size, surface treatment, and installation method of the seal. Common diaphragm sealing materials for metering pumps include fluororubber, silicone rubber, nitrile rubber, etc. Different materials have different properties such as corrosion resistance, wear resistance, and high temperature resistance, and need to be selected based on specific working environments and requirements. When selecting sealing material, it is also necessary to pay attention to its compatibility with the metering pump diaphragm and pump casing to ensure sealing performance.

At the same time, the shape and size of the seal also need to be considered. In general, the shape of the diaphragm seal of the metering pump should match the shape of the pump chamber to ensure uniform distribution of liquid flow and compressed air. The surface treatment and installation method of seals also need to be noted to meet specific working environments and requirements. For example, lubrication treatment on the surface of sealing components can reduce friction coefficient and improve sealing performance; The correct installation method can avoid damage and leakage of the seals.

In short, the diaphragm seal of the metering pump is an important component of the metering pump, which is crucial for the metering pump

隔膜泵具有输送扬程长、流速低、能够输送磨料颗粒、高粘度和腐蚀性等危险液体的特点，是全球工业中重要的动力设备。东晟密封件料作为隔膜泵膜片密封件，也是一种氟塑料橡胶产品，是许多隔膜泵的隔膜密封附件。

Diaphragm pumps have the characteristics of long transportation head, low flow rate, and the ability to transport hazardous liquids such as abrasive particles and high viscosity and corrosion, making them an important power equipment in the global industry. Qisheng New Material, as a diaphragm pump diaphragm seal, is also a type of fluorine plastic rubber product that is a type of diaphragm seal accessory in many diaphragm pumps.

隔膜泵的传统平板膜片（又叫隔膜泵膜片密封件）的侧视图（图1）在实际运行中主要包括两个阶段：

The side view (Figure 1) of the traditional flat diaphragm (also known as diaphragm pump diaphragm seal) of a diaphragm pump mainly includes two stages during actual operation:

• 排放阶段和吸入阶段。当柱塞在变速箱系统的驱动下向右移动时，油室的容积增加，压力降低，导致隔膜向右移动。浆液室的容积逐渐增大，压力逐渐减小。排出阀逐渐关闭，入口压力降低，造成入口阀内外压差，使浆液逐渐进入隔膜室；

1、 Discharge stage and suction stage. When the plunger moves to the right under the drive of the transmission system, the volume of the oil chamber increases and the pressure decreases, causing the diaphragm to move to the right. The volume of the slurry chamber gradually increases, and the pressure gradually decreases. The discharge valve gradually closes, and the pressure at the inlet decreases, causing a difference in pressure inside and outside the inlet valve, causing the slurry to gradually enter the diaphragm chamber;

2、 当变速箱系统驱动转向柱向左移动时，油室的容积逐渐减小，压力逐渐增大。当平板膜片（又叫隔膜泵膜片密封件）在压差作用下向左移动时，浆液室的容积逐渐减小，压力增加。进料阀在压差作用下逐渐关闭，出料阀在两侧压差的作用下打开，逐渐排出腔内的流体，在往复运动过程中完成浆液的输送。

2、 Similarly, when the column is driven by the transmission system to move to the left, the volume of the oil chamber gradually decreases and the pressure gradually increases. When the flat diaphragm (also known as the diaphragm pump diaphragm seal) moves to the left under the pressure difference, the volume of the slurry chamber gradually decreases and the pressure increases. The inlet valve gradually closes under the pressure difference, and the discharge valve opens under the pressure difference on both sides, gradually discharging the fluid in the chamber, Complete the transportation of slurry during reciprocating motion.

可以看出，隔膜泵中的平板膜片（又叫隔膜泵膜片密封件）起到密封隔膜泵轴、分离液压油和输送浆液的作用，使输送浆液只与隔膜室内的部件接触，不与动力端密封装置接触，确保这些部件的使用寿命。此外，平板膜片（又叫隔膜泵膜片密封件）是隔膜泵的排放隔膜，与隔膜泵的排量密切相关。因此，隔膜泵中平板隔膜（也称隔膜泵膜片密封件）的使用寿命是直接影响隔膜泵运行时间和工作效率的重要因素之一。

It can be seen that the flat diaphragm (also known as the diaphragm pump diaphragm seal) in the diaphragm pump plays a role in sealing the shaft of the diaphragm pump, separating the hydraulic oil and the conveying slurry, so that the conveying slurry only comes into contact with the components in the diaphragm chamber and does not come into contact with the power end sealing device, ensuring the operating life of these components. Moreover, the flat diaphragm (also known as the diaphragm pump diaphragm seal) serves as the discharge membrane of the diaphragm pump and is closely related to the displacement of the diaphragm pump. Therefore, the service life of the flat diaphragm (also known as the diaphragm pump diaphragm seal) in the diaphragm pump is one of the important factors that directly affect the operating time and work efficiency of the diaphragm pump.

隔膜泵是借助薄膜将被输液体与活柱和泵缸隔开，从而保护活柱和泵缸。东晟密封件告诉您隔膜泵中隔膜片密封件它是依靠一个隔膜片密封件的来回鼓动改变工作室容积从而吸入和排出液体的作用。

隔膜片密封件泵膜片容易损坏的原因有以下方面：

• 由于隔膜片密封件室体积一定，若进料不稳定，压力低，使进料补偿器的料位低于2m，稳压装置中的料位不正常，进料时泵内料浆分离形成空隙，造成缺料、打空泵，产生锤击或撞击甚至汽蚀，使隔膜片密封件承受的变应力增大，频率增加，造成隔膜片密封件疲劳损坏或击穿。

• 隔膜片密封件室空气没有排干净，气体的体积随着推进液压力的变化而变化，形成气锤，隔膜片密封件局部受力增大，将隔膜片密封件打破。

• 进料温度超过规定的100℃，加速隔膜片密封件老化，同时，料浆中产生蒸气泡，气体进入隔膜片密封件室或卸荷阀泄漏时，推进液压力降低，均造成隔膜片密封件受力不均，疲劳损坏。

• 进料中含有3-8mm石子儿或大块物料及料浆中固体质量百分比超过20%，引起卡阀，造成泵压力波动，或由于阀装配时，阀锥定位不准，引起刺阀，导致隔膜片密封件瞬间受力加大；引起破裂。

• 隔膜片密封件室的进料和排料是通过探头检测控制杆位置倍号控制的，若控制杆上的磁环磁性弱，探头检测不到信号，不能及时补排油，导致隔膜片密封件单侧受力过大而破裂。

• 隔膜片密封件控制杆的支承套磨损严重，使控制杆偏心、下沉，隔膜片密封件受力增加，易拉裂隔膜片密封件。

• 机组出现压差，引起气动隔膜片密封件泵超压，隔膜片密封件承受瞬时力增大引起破裂。

• 十字头、活塞或油缸内衬松动，十字头导轨、十字头轴承安装不正确等引起活塞的锤击，都会使液力不平衡；泵频繁跳停，也会使隔膜片密封件瞬时受力达到极限，造成隔膜片密封件破裂。

• 氮气包预先充2MPa的氮气，有较好的阻尼效果。操作运行时，压力表上反映的压力是操作压力而不是氮气包的压力(只有停泵时才能看到)，若操作时氮气包损坏或压力降低，隔膜片密封件泵处于无阻尼状态下运行，将导致液力不平衡，隔膜片密封件易发生撞击而损坏。

10、隔膜片密封件片自身质量差，无弹性，材料强度低。
