隔膜泵膜片密封件的2點工作原理（圖）
隔膜泵具有輸送揚程長、流速低、能夠輸送磨料顆粒、高粘度和腐蝕性等危險液體的特點，是全球工業中重要的動力設備。東晟密封件料作為隔膜泵膜片密封件，也是一種氟塑料橡膠產品，是許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.
隔膜泵的傳統平板膜片（又叫隔膜泵膜片密封件）的側視圖（圖1）在實際運行中主要包括兩個階段：
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:
1、 排放階段和吸入階段。當柱塞在變速箱系統的驅動下向右移動時，油室的容積增加，壓力降低，導致隔膜向右移動。漿液室的容積逐漸增大，壓力逐漸減小。排出閥逐漸關閉，入口壓力降低，造成入口閥內外壓差，使漿液逐漸進入隔膜室；
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、 當變速箱系統驅動轉向柱向左移動時，油室的容積逐漸減小，壓力逐漸增大。當平板膜片（又叫隔膜泵膜片密封件）在壓差作用下向左移動時，漿液室的容積逐漸減小，壓力增加。進料閥在壓差作用下逐漸關閉，出料閥在兩側壓差的作用下打開，逐漸排出腔內的流體，在往復運動過程中完成漿液的輸送。
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）起到密封隔膜泵軸、分離液壓油和輸送漿液的作用，使輸送漿液只與隔膜室內的部件接觸，不與動力端密封裝置接觸，確保這些部件的使用壽命。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，與隔膜泵的排量密切相關。因此，隔膜泵中平板隔膜（也稱隔膜泵膜片密封件）的使用壽命是直接影響隔膜泵運行時間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.
