What are the precautions when using a high-pressure oil pump to clear pipes?

Before using a high-pressure pump for pipeline cleaning, we must first inspect the nozzle to ensure it is not clogged.

2. During the cleaning and construction process, it's crucial to pay attention to the placement of the nozzle. Generally, the nozzle should be inserted about 30 centimeters into the pipe, followed by applying pressure to push the nozzle into the pipe. The positioning and pressure application at this location are both essential.

After the cleaning is completed, we must promptly pull the nozzle out of the pipeline to avoid injury to staff from the nozzle's swing, and quickly adjust the pressure of the high-pressure pump to zero.
