1. Before using high-pressure oil pump for pipeline cleaning, we should first check the nozzle to ensure that its nozzle is not blocked.
2. During cleaning and construction, we should pay attention to the position of the nozzle. Generally, the nozzle shall be placed about 30cm in the pipeline, and then the nozzle shall be pressurized and sent into the pipeline. The placement and pressurization operation of this position are very important.
3. After the cleaning work is completed, even if we pull the nozzle out of the pipeline, in order to avoid injury to the staff caused by the swing of the nozzle, we should adjust the pressure of the high-pressure pump to zero as soon as possible.
