[0001] The utility model belongs to the field of high-pressure pumps, and in particular relates to a slideway hole sealing structure of a high-pressure pump in a coal mine. Background Art

[0002] In a high-pressure pump, the slideway hole is usually used in conjunction with bearings, bushings and other components to jointly bear the workload of the high-pressure pump. The slideway hole usually refers to the cylindrical inner surface inside the high-pressure pump used to install and support sliding parts (such as crankshafts, pistons, etc.). These holes need to have high precision and appropriate surface roughness to ensure that the sliding parts can move smoothly and stably.

[0003] The existing high-pressure pump slideway hole has no corresponding sealing structure, which will reduce the sealing effect of the slideway hole inside the high-pressure pump and cannot ensure that the sliding parts can move smoothly and stably, thus affecting the normal use of the high-pressure pump.

[0004] In view of this, the present utility model is proposed. Utility Model Content
