求翻译：用增压泵向设备注入清水达实验压力，保压30min后将压力降至规定试验压力的80%，保持足够的时间对所有的焊缝和连接部位进行检查。是什么意思？

Water booster pump to the device up to the experimental pressure, holding pressure 30min after the pressure dropped to 80% of the required test pressure and maintain adequate time to check all the welds and joints.

equipment used to inject water booster pump pressure to keep pressure up to experiment after 30 min the pressure test pressure dropped to under 80 percent in order to maintain adequate time for all of the welding seams and linked parts for inspection.

Pours into the clear water with the booster pump to the equipment to reach the experimental pressure, after guarantees presses 30min the pressure drop to the stipulation test pressure 80%, maintains the enough time carries on the inspection to all welded joints and the connection spot.

Experimental pressure booster pump pumping water into the device, packing required test pressure by lowering the pressure 80% after 30min, enough time to check all welds and joints.
