使用高压泵疏通管道时应注意的事项有哪些？

What should be noticed when using a high pressure pump to dredge the pipe?

1、在使用高压泵进行管道清洗之间，我们要首先对喷嘴进行检查，要保证它的喷嘴没有出现堵塞的现象。

1, in the use of high pressure pumps for pipeline cleaning, we should first check the nozzle, to ensure that its nozzle has not been blocked.

2、在进行清洗和施工的时候，需要我们注意的是放置喷头的位置。一般的要把喷头放进管道中大约30厘米的地方，然后在对喷头进行加压，把喷头送入到管道当中，这个位置的放置和加压的操作都是非常重要的。

2. When cleaning and construction, we need to pay attention to the position of the sprinkler. In general, put the sprinkler into the pipe about 30 centimeters, then pressurize the sprinkler and send the sprinkler into the pipeline. The placement of this position and the operation of pressurization are very important.

3、在清洗工作完成了之后，我们还要即使把喷头从管道里拉出来，为了避免喷头甩动对工作人员造成伤害，应当尽快的将高压泵的压力调到零。

3, after the completion of the cleaning work, we should even pull the nozzle out of the pipeline. In order to avoid damage to the workers caused by the sprinkler swing, the pressure of the high pressure pump should be transferred to zero as soon as possible.
