Because of the high jet speed and great pressure, well washing by high pressure auto rotate jet technology is very suitable to the washing of water supply tube well like water well, geothermic conditioner well and geothermal well with the advantages of auto rotate, no-pollution to the environment and equipments, high washing efficiency and low cost; and water yield can be increased or recharge well recharged. The paper introduces the structure principle and the application effects of high pressure jet equipment.
