立式丁基胶涂布机的核心工作逻辑可拆解为两条主线：

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

1. 供料系统——螺旋转子泵

1. Feeding system - spiral rotor pump

设备采用螺旋转子泵作为供料动力装置。当被输送的丁基胶（通常需加热至近140°C液化）通过进液管时，离心力将胶体从转子叶轮中甩出，获得一定动能（即压力），流入定压室与静压箱产生真空后，经定量阀进入定量室并保持恒定状态。转子持续转动，胶体周而复始循环流动，直至达到所需浓度，从而实现流量大且稳定可靠的连续供料。

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. 涂布系统——液压缸双向运动

2. Coating System - Hydraulic Cylinder Bidirectional Motion

液压系统根据国外样机测绘制造，通过电磁换向阀控制液压缸实现双向运动：

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:

动作电磁铁状态液压缸运动功能

Action electromagnet status, hydraulic cylinder movement function

涂胶1YA通电，换向阀左位接入缸体由右向左运动挤出丁基胶进行涂布

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

保压1YA断电，换向阀中位液控单向阀+蓄能器保压压力降至下限时自动补压

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通电，换向阀右位接入缸体由左向右运动活塞杆退回，准备下一循环

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

系统利用电接点压力表实时调节压力：当无杆腔压力升至上限，触点发出信号使1YA断电、液压泵关闭，由蓄能器保压；压力降至下限时自动恢复供油。这一闭环控制确保涂布压力始终稳定在工作范围内。

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，液压缸与丁基胶缸安装在同一水平线上，两者之间的间隔用于充添固体丁基胶。

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.
