Description

Technical Field

[0001] This utility model relates to the field of stuffing box structure technology, and specifically to a stuffing box assembly structure. Background Technology

[0002] The stuffing box assembly is located inside the hydraulic end cylinder liner. Its core task is to form a dynamic seal between the high-speed reciprocating plunger and the stationary pump body to prevent the high-pressure, sometimes high-temperature, corrosive, or abrasive media being pumped from leaking to the outside. Traditional stuffing seals are prone to leakage, have short service life, require frequent adjustment of the clamping force, and have a large maintenance workload. Moreover, the leaked media may pose a threat to environmental safety and human health. Therefore, there is an urgent need for a stuffing box assembly structure to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a packing box assembly structure to address the aforementioned shortcomings in the prior art.

[0005] Preferably, a groove is provided at one end of the packing box body, and a sealing ring is provided inside the groove.

[0006] Preferably, the outer wall of the locking nut is provided with a second groove, and a second sealing ring is provided inside the second groove, the second sealing ring being in contact with the packing box body. Preferably, a water seal ring is provided inside the stuffing box body. The water seal ring is located inside the locking nut and is connected to the sealing sleeve and the sealing plug.

[0007] Preferably, the outer wall of the water seal ring is provided with a groove three, and a sealing ring three is provided inside the groove three, the sealing ring three being in contact with the inner wall of the locking nut.

[0008] Preferably, the water seal ring includes a cooling water seal, which is located inside the water seal ring.

[0009] In the above technical solution, the present invention provides a stuffing box assembly structure, (1) modular design: the traditional stuffing rings that need to be installed individually are integrated into a pre-compressed integral module. During installation, the entire module is simply placed into the stuffing box, which greatly simplifies the installation process, avoids sealing failure caused by improper manual installation, and improves replacement speed and reliability.

[0010] (2) By setting up an innovative combination of seasoning boxes, the plunger seal can be replaced without removing the pump head. It can be replaced simply by removing the lock nut, which greatly reduces disassembly time, reduces the number of times the pump head bolts are disassembled, and improves the service life of the bolts.

[0011] (3) Lubrication and heat dissipation area: The area of ​​the locking nut is designed with channels to allow the introduction of clean cooling water for lubrication and cooling. Attached Figure Description
