The utility model discloses a shaft seal structure for a high-pressure pump, which relates to the technical field of high-pressure pump shaft seals and comprises a shaft seal main body. The shaft seal body, the pipeline groove, the connecting column, the pressure reducing spring, the fixing rod, the supporting block, the fixing spring, the sealing column, the connecting rod, the limiting block, the sealing groove and the plastic film are matched, and the pipeline groove is used for being connected with a water pipe of a high-pressure pump; a buffer groove in the top is used for relieving impact of water pressure, a sealing plate connected with a fixing spring can fix the space range of an inflow groove, the situation that the water pressure is too large and cannot be fixed is avoided, the sealing performance can be enhanced when the water pipe reaches the top through a sealing groove through a sealing column, and the whole water pipe can be wrapped through the sealing groove; and the plastic film on the inner
