丁基胶涂布机气液增压站的维护及维修
Maintenance and repair of gas-liquid booster station of butyl rubber coater
一、 丁基胶涂布机系统打开后，油缸无动作（系统无压力）
1、 After the butyl adhesive coater system is opened, the oil cylinder does not act (the system has no pressure)
1、 检查外接气源是否正常。
1. Check whether the external air source is normal.
2、 检查打开液压电机开关后，系统电磁阀是否正常换向。
2. Check whether the system solenoid valve reverses normally after opening the hydraulic motor switch.
3、 减压阀是否已打开。
3. Whether the pressure reducing valve is open.
4、 检查气液增压站上的气管是否有气压。
4. Check whether there is air pressure in the air pipe on the gas-liquid booster station.
5、 如都正常，用平口螺丝刀按一下增压缸两端的小换向阀上的铜触头。
5. If it is normal, press the copper contact on the small reversing valve at both ends of the booster cylinder with a flat screwdriver.

二、 丁基胶涂布机系统只进不退
2、 Butyl rubber coater system is only in and out
1、 反复打开关阀胶缸操作退开关，看是否能解决。
1. Repeatedly open the valve closing rubber cylinder operation return switch to see if it can be solved.
2、 胶缸操作退打开时，看液压换向阀上的灯是否亮。
2. When the rubber cylinder is opened, check whether the light on the hydraulic directional valve is on.
3、 液压换向阀被杂物卡住，需拆下清洗。
3. The hydraulic directional valve is stuck by sundries and needs to be removed for cleaning.
4、 用铁片挡在液压换向阀的线圈端，灯亮时看是否有磁性，如无，需更换液压换向阀的伐圈，如有，需将换向阀拆下清洗。
4. Block the coil end of the hydraulic directional valve with an iron sheet. When the light is on, check whether it is magnetic. If not, replace the cutting ring of the hydraulic directional valve. If so, remove the directional valve for cleaning.
