Problems solved by technology

[0004] However, during the high-speed friction and vibration of the piston rod of the device, it is easy to cause the root of the rod sealing ring to contact the groove and cause extrusion and gnawing, which eventually leads to premature damage of the rod sealing ring, so the service life is short and the product experience is poor. Poor, practicality needs to be improved

Abstract

The invention discloses a large hydraulic breaking hammer sealing system which comprises a piston rod. The outer surface of the piston rod is sleeved with an upper guide sleeve and a lower guide sleeve; a first groove, a third groove and two second grooves are formed in the upper guide sleeve, and the two second grooves are located between the first groove and the third groove. A rod sealing ring is arranged in the first groove; a buffer ring and an O-shaped ring are arranged in the second grooves; a double-sealing ring is arranged in the third groove; a mounting groove, a fifth groove and two fourth grooves are formed in the lower guide sleeve, and the two fourth grooves are located between the mounting groove and the fifth groove; and a dustproof sealing ring is arranged in the mounting groove. According to the large hydraulic breaking hammer sealing system, through cooperation of the rod sealing ring, the first groove and the like, a large chamfer is correspondingly formed in the root of the rod sealing ring, extrusion gnawing caused by contact between the root of the rod sealing ring and the piston rod is avoided, and the service life of the rod sealing ring is prolonged.

Description

Technical field[0001]The present invention relates to the field of hydraulic crushing hammer seal, in particular, involving a large hydraulic crushing hammer seal system.Background technique[0002]The power source of hydraulic crushing hammers is the pressure provided by excavators, loaders, or pumping stations, which can break the stone and rocks in engineering construction, and improve work efficiency. The working principle is to drive the piston reciprocating motion, drive the piston reciprocating, and the piston stroke is high-speed hitting the boom, which is broken by the brazing rod to crush the ore, concrete and other solid.[0003]According to the patent number CN211398116U, a cylinder block, including a cylinder block, a piston located within the cylinder block, a cylinder block and a piston, a gap seal, and a lower seal, and a lower seal including two The main seal structure; has the advantages of stable reliability, extending the service life of the seal.[0004]However, the p...
