不论是修补过后的盐水机组，仍是新安装的，或许压缩机进行空气负荷试运转合格后的，咱们都要对该盐水机组的全部体系进行吹除排污，以清除机组制冷体系内部的焊渣、砂子和铁屑等杂物。
Whether after the repair of saline water machine, is a new installation, or air compressor load test run after passing, we are all on the system unit for blowing saline sewage, to clear the internal cooling system of welding slag, sand and debris.
咱们常用的风冷盐水机组、水冷盐水机组或螺杆式盐水机组等，尽管机组有所不同，但是操作方法大致相像，详细的要求和步骤如下：
We commonly used air - cooled brine unit, water - cooled brine unit or screw brine unit, and so on, although the unit is different, but the operation method is roughly similar, the detailed requirements and steps are as follows:
1、选用压力为0.6Mpa（表压）的清洁压缩空气或氮气进行吹扫，次数不少于3次。在吹扫过程中，还要用白纸在排污口试验，直到排出气体不带水汽、油污、铁锈等杂物停止。
1, the pressure of 0.6Mpa (g) clean compressed air or nitrogen purge, not less than 3 times. In the blowing process, but also with a white paper in the outfall test, until the exhaust gas without water, oil, rust and other debris to stop.
假如有发现管路或阀门有显着的漏气点，要及时进行补焊，并将阀门的法兰紧好。
If you have found that the pipeline or the valve has a significant leak point, to be timely repair welding, and the flange of the valve is good.
2、在给盐水机组的体系排污后，记住将体系中所有的阀（除安全阀外）拆开清洁，保持洁净度。假如有阀门的阀芯或密封线有损坏，要及时进行修补或更换。
2, after the system of water to the brine unit, remember to all the valve (in addition to the safety valve) apart clean, clean degree. If there is a valve spool or sealing line is damaged, to be repaired or replaced in a timely manner.
除了给盐水机组的全部体系进行排污作业外，还要做气密性试验，真空试验，以及充制冷剂试漏等试运转程序。
In addition to the whole system of water to the brine unit for sewage operations, but also to do the air tightness test, vacuum test, as well as test run procedures such as filling refrigerant test.
