Single line two-part oil-gas lubrication system
单线递进二级分配式油气润滑系统，主要由油-气供应站(自带压缩空气处理单元和PLC电气控制箱)、一级递进式单线油分配器(KM、KL、SMX型)、二级递进分配式油气混合器(SMX-YQ型)以及系统连接的管路和附件等组成。
Gdko3 type electric control box has two types: monitoring and full-automatic. It is applicable to the 40MPa double line terminal dry oil centralized lubrication system. It is used to control the coordinated work of the lubrication pump, reversing valve, grease replenishing pump, etc. it can automatically supply oil to the oil supply points in the system. After the oil supply is completed, it will automatically stop. When the liquid level in the oil tank is lower than a certain limit, the grease replenishing pump will start automatically and stop automatically after filling with oil.

Product Description
1、 Overview
Gdko3 type electric control box has two types: monitoring and full-automatic. It is applicable to the 40MPa double line terminal dry oil centralized lubrication system. It is used to control the coordinated work of the lubrication pump, reversing valve, grease replenishing pump, etc. it can automatically supply oil to the oil supply points in the system. After the oil supply is completed, it will automatically stop. When the liquid level in the oil tank is lower than a certain limit, the grease replenishing pump will start automatically and stop automatically after filling with oil.
This control box can send out fault signals such as "extended oil supply time", "empty oil reservoir", "overload operation", etc. It has continuous, manual and automatic control working states, which can be switched through the change-over switch on the box surface. Continuous working state: when the lubricating pump is started, it continuously supplies lubricating grease to the two main lines of the system; Manual working state: when the interlocking signal with the main engine is connected, the lubricating pump is manually started to feed the lubricating grease to the steering system, and the automatic reversing is automatically stopped after one lubrication cycle is completed; Automatic working state: when the interlocking signal with the main engine is connected, the lubricating pump will supply lubricating grease to the system at regular intervals according to the time interval set by the system, and it will automatically stop after completing a lubrication cycle. No matter what state the lubricating pump is in, once the oil reservoir is empty, the grease replenishing pump will automatically start to replenish grease and stop automatically after replenishing.

一、系统组成及应用范围
单线递进二级分配式油气润滑系统，主要由油-气供应站(自带压缩空气处理单元和PLC电气控制箱)、一级递进式单线油分配器(KM、KL、SMX型)、二级递进分配式油气混合器(SMX-YQ型)以及系统连接的管路和附件等组成。适用于润滑点多(约250点以下)，现场设备工况条件好的场合。
二、系统原理图
三、工作原理
如上图所示，油-气供应站设有一根供油主管和一根供气主管，供油主管接至主分配器，各油气分配混合器进气口均并接在供气主管上。系统工作时，供气主管内压缩空气常通，供应站上油泵按系统设定的时间向供油主管供油，压力油进入主分配器后，由主分配器按比例分配后送入下一级油气分配混合器，再由油气分配混合器将润滑油按比例分配后送至各出油口，在出油口与压缩空气混合，并在压缩空气的带动下送入各润滑点。
四、系统特征
1、设置有油-气供应主站，油箱容积≥500L，供气管径≥DN20;
2、设置有一级单线递进式油分配器，可对系统每次给油进行循环记数监测控制;
3、设置有压缩空气处理装置，可对供向系统所有二级递进分配式油气混合器的压缩空气进行预处理;
4、设置有PLC电气控制箱，可对系统的运行工况实行程序化全自动控制;
5、一级单线递进式油分配器和二级递进分配式油气混合器，是定量容积式分配器，油量不能调节，只能在设计时选择不同规格进行组合，因其内部均有运动件，所以不适宜在高温区域安装使用。
6、此系统扩展性受限制，在现场不能随意增减油气供应点。
