丁基胶涂布机液压系统是根据国外引进的样机进行测绘制造的，其组成如下图1所示。

　　The hydraulic system of the butyl rubber coating machine was surveyed and manufactured based on a prototype imported from abroad, and its composition is shown in Figure 1.

　　图1(a)和图1(b)所示系统在实际中都有应用，二者原理相似，现以图1 (b)为例给大家讲解下油路工作原理。

　　The systems shown in Figure 1 (a) and Figure 1 (b) have practical applications, and their principles are similar. Now, taking Figure 1 (b) as an example, we will explain the working principle of the oil circuit.

　　工作原理：当1YA通电，换向阀左位接入回路，液压缸5由右向左运动挤出丁基胶进行涂胶。当液压缸无杆腔压力上升至电接点压力表8的上限值时，压力表触点发出信号，使电磁铁1YA断电，换向阀处于中位，同时液压泵关闭，液压缸由液控单向阀4及蓄能器7保压。当液压缸无杆腔压力下降到电接点压力表调定的下限值时，压力表又发出信号，使IYA通电，液压泵再次向系统供油，使无杆腔压力上升，从而使液压缸的压力保持在要求的工作范围内。当液压缸活塞到达终点前的预定位置时，电磁铁2YA通电，换向阀右位接入回路，液压缸由左向右运动，活塞杆退回。需要指出的是：液压缸5和丁基胶缸6安装在同一水平线上，并分别固定在支架上，两者之间的间隔是用来充填固体丁基胶的。

　　Working principle: When 1YA is powered on, the left position of the directional valve is connected to the circuit, and hydraulic cylinder 5 moves from right to left to extrude butyl rubber for coating. When the pressure in the rodless chamber of the hydraulic cylinder rises to the upper limit value of the electric contact pressure gauge 8, the pressure gauge contact sends a signal to cut off the power of the electromagnet 1YA, the reversing valve is in the neutral position, and the hydraulic pump is closed. The hydraulic cylinder is maintained by the hydraulic control check valve 4 and the accumulator 7. When the pressure in the rodless chamber of the hydraulic cylinder drops to the lower limit set by the electric contact pressure gauge, the pressure gauge sends a signal to energize IYA, and the hydraulic pump supplies oil to the system again, causing the rodless chamber pressure to rise, thereby maintaining the pressure of the hydraulic cylinder within the required working range. When the hydraulic cylinder piston reaches the predetermined position before the end point, the electromagnet 2YA is energized, and the directional valve is connected to the circuit in the right position. The hydraulic cylinder moves from left to right, and the piston rod retracts. It should be pointed out that hydraulic cylinder 5 and butyl rubber cylinder 6 are installed on the same horizontal line and fixed on the bracket respectively, and the gap between the two is used to fill solid butyl rubber.
