Problems solved by technology
When replacing, it is necessary to remove the sealing end cover first, and then remove the packing sealing ring, which is extremely inconvenient to replace. After the replacement, it must be installed in the opposite order. The replacement time is long, which increases the unnecessary downtime of the oil pump and reduces the Productivity
The single way of using the packing seal makes the service life of the packing sealing ring short and increases the replacement frequency of the packing sealing ring

Embodiment Construction
[0014] The present invention is described below in conjunction with accompanying drawing.
[0015] as attached figure 2 The shown gland assembly of the present invention includes a gland body 4, a shaft hole 5 is opened in the center of the gland body 4, and a shaft hole 5 is formed on the outer end surface of the gland body 4. The ring groove 6 connected with the holes 5; the ring groove 6 is provided with a packing sealing ring 3; the length of the packing sealing ring 3 is less than the length of the sealing gland body 4, and the inner diameter is smaller than the aperture of the shaft hole 5; The outer end surface of the sealing gland body 4 is connected with a gland plate 8 that compresses the packing seal ring 3 through countersunk bolts 7; two countersunk bolts 7 are arranged symmetrically; Step labyrinth groove 9 is arranged.
[0016] as attached image 3 As shown in the sealing gland assembly of the present invention, when in use, since the inner diameter of the p...

The invention discloses a sealing gland component which comprises a sealing gland body, wherein a shaft hole is formed in the center of the sealing gland body, and a ring groove communicated with the shaft hole is arranged on the outer end surface of the sealing gland body; a packing seal ring is arranged in the ring groove; the length of the packing seal ring is shorter than the length of the sealing gland body, and inner diameter of the packing seal ring is smaller than the aperture of the shaft hole; a gland plate for compressing the sealing gland body is arranged on the outer end surface of the sealing gland body through a fixing element; and a stepped type labyrinth groove is arranged in the sealing gland body. The sealing gland component disclosed by the invention has good sealing performance; the packing seal ring is simple and convenient in replacement, so as to greatly reduce replacement time, reduce unnecessary shutdown time of an oil pump and reduce production efficiency; and the life cycle of the pacing seal ring is long, so as to reduce the replacement frequency of the packing seal ring.
Description
technical field [0001] The invention relates to a sealing gland assembly, in particular to a sealing gland assembly used in an oil pump, and belongs to the technical field of sealing devices. Background technique [0002] Today's oil pumps usually use packing seals, such as attached figure 1 As shown, a sealing gland 2 is provided on the pump shaft 1, and a packing sealing ring 3 is provided between the pump shaft 1 and the sealing gland 2. Generally, the length of the packing sealing ring 3 is the same as that of the sealing gland 2 . After long-term use, the packing sealing ring will wear out, and the oil pump will leak oil. At this time, the packing sealing ring needs to be replaced. When replacing, it is necessary to remove the sealing end cover first, and then remove the packing sealing ring, which is extremely inconvenient to replace. After the replacement, it must be installed in the opposite order. The replacement time is long, which increases the unnecessary downt...
