立式丁基膠涂布機(jī)的核心工作邏輯可拆解為兩條主線：

The core working logic of the vertical butyl rubber coating machine can be broken down into two main lines:

1. 供料系統(tǒng)——螺旋轉(zhuǎn)子泵

1. Feeding system - spiral rotor pump

設(shè)備采用螺旋轉(zhuǎn)子泵作為供料動(dòng)力裝置。當(dāng)被輸送的丁基膠（通常需加熱至近140°C液化）通過進(jìn)液管時(shí)，離心力將膠體從轉(zhuǎn)子葉輪中甩出，獲得一定動(dòng)能（即壓力），流入定壓室與靜壓箱產(chǎn)生真空后，經(jīng)定量閥進(jìn)入定量室并保持恒定狀態(tài)。轉(zhuǎn)子持續(xù)轉(zhuǎn)動(dòng)，膠體周而復(fù)始循環(huán)流動(dòng)，直至達(dá)到所需濃度，從而實(shí)現(xiàn)流量大且穩(wěn)定可靠的連續(xù)供料。

The equipment adopts a spiral rotor pump as the feeding power device. When the conveyed butyl rubber (usually heated to nearly 140 ° C for liquefaction) passes through the inlet pipe, centrifugal force throws the colloid out of the rotor impeller, obtaining a certain kinetic energy (i.e. pressure), flowing into the constant pressure chamber and static pressure box to create a vacuum, and then entering the constant pressure chamber through the quantitative valve and maintaining a constant state. The rotor continues to rotate, and the colloid flows in a cyclic manner until the desired concentration is reached, thereby achieving a large flow rate and stable and reliable continuous feeding.

2. 涂布系統(tǒng)——液壓缸雙向運(yùn)動(dòng)

2. Coating System - Hydraulic Cylinder Bidirectional Motion

液壓系統(tǒng)根據(jù)國外樣機(jī)測繪制造，通過電磁換向閥控制液壓缸實(shí)現(xiàn)雙向運(yùn)動(dòng)：

The hydraulic system is manufactured based on foreign prototype surveying and mapping, and the hydraulic cylinder is controlled by an electromagnetic directional valve to achieve bidirectional movement:

動(dòng)作電磁鐵狀態(tài)液壓缸運(yùn)動(dòng)功能

Action electromagnet status, hydraulic cylinder movement function

涂膠1YA通電，換向閥左位接入缸體由右向左運(yùn)動(dòng)擠出丁基膠進(jìn)行涂布

Apply glue 1YA and power on. Connect the left position of the directional valve to the cylinder block and move from right to left to extrude butyl glue for coating

保壓1YA斷電，換向閥中位液控單向閥+蓄能器保壓壓力降至下限時(shí)自動(dòng)補(bǔ)壓

When the 1YA pressure is maintained and the power is cut off, the directional valve, the center position hydraulic control check valve, and the accumulator will automatically replenish the pressure when the pressure drops to the lower limit

退回2YA通電，換向閥右位接入缸體由左向右運(yùn)動(dòng)活塞桿退回，準(zhǔn)備下一循環(huán)

Return 2YA to power on, connect the directional valve to the cylinder body in the right position, and move the piston rod from left to right to retract, preparing for the next cycle

系統(tǒng)利用電接點(diǎn)壓力表實(shí)時(shí)調(diào)節(jié)壓力：當(dāng)無桿腔壓力升至上限，觸點(diǎn)發(fā)出信號(hào)使1YA斷電、液壓泵關(guān)閉，由蓄能器保壓；壓力降至下限時(shí)自動(dòng)恢復(fù)供油。這一閉環(huán)控制確保涂布?jí)毫κ冀K穩(wěn)定在工作范圍內(nèi)。

The system uses an electric contact pressure gauge to adjust pressure in real time: when the pressure in the rodless chamber rises to the upper limit, the contact sends a signal to cut off power to 1YA and shut down the hydraulic pump, which is maintained by the accumulator; Automatically resume fuel supply when the pressure drops to the lower limit. This closed-loop control ensures that the coating pressure remains stable within the working range.

值得注意的是，液壓缸與丁基膠缸安裝在同一水平線上，兩者之間的間隔用于充添固體丁基膠。

It is worth noting that the hydraulic cylinder and the butyl rubber cylinder are installed on the same horizontal line, and the gap between the two is used to fill solid butyl rubber.
