Description

Circumferential water cooling packing

technical field

The invention relates to a packing, and more specifically, the present invention mainly relates to a circumferential water-through cooling packing in which water channels are circumferentially arranged in the packing.

Background technique

The packing is one of the core parts of the reciprocating piston compressor, which is a component that prevents the gas in the cylinder from leaking from between the piston rod and the cylinder. The basic requirements for the packing are good sealing performance and durability.

In an oil-free lubricated compressor, the heat generated by the gas and the frictional heat between the packing box and the piston rod can easily lead to the failure of the packing. Conventional packing cooling channel is designed to drill water channel openings on each packing box. The cooling water flows through the stuffing box through the axial cooling water channel to take away heat. Because the cooling water channel is limited by the size of the stuffing box, the flow area is small, resulting in unsatisfactory cooling effect.

A further technical solution is: the water inlet on the first mating surface is connected to the water outlet on the second mating surface, the water channel runs through the packing monomer in the circumferential direction, and each water channel surrounds a 1/2 ring;

A further technical solution is: the filler monomer includes at least two water channels;

A further technical solution is: the cooperation between the filler monomers is that the water inlet on the first mating surface of the second filler monomer is connected to the water outlet on the second mating surface of the first filler monomer;

A further technical solution is: the filler monomer is annular;

A further technical solution is: the tie rod passes through the tie rod opening to connect multiple packing monomers.

Compared with the prior art, one of the beneficial effects of the present invention is: by improving the arrangement of the packing cooling water channel, the cooling water channel is changed from the traditional axial water channel mouth to the circumferential water channel, and the flow area is increased by nearly 1 /3, improve the cooling effect.

Considering the above-mentioned problems of the prior art, according to one aspect disclosed by the present invention, the present invention adopts the following technical solutions:

As shown in Figure 1, the present invention provides a circumferential water-through cooling filler, including a filler body and a water channel 6, the water channel 6 is arranged on the filler body, and includes at least one filler monomer 1, and the filler monomer 1 includes a first mating surface 7 and The second mating surface 8, the first mating surface 7 is exactly one side of the annular packing monomer, and the second mating surface 8 is the other side of the annular packing monomer, and the first mating surface 7 is provided with at least one Through hole 9, at least one through hole 9 is provided on the filler monomer 1, the first mating surface water inlet 2 and the first mating surface water outlet 4 are also arranged on the first mating surface 7, the first mating surface water inlet 2 The water outlet 3 of the second mating surface is connected to the water outlet 3 of the second mating surface through a water channel 6 arranged in a spiral shape in the circumferential direction in the packing body, and the water outlet 4 of the first mating surface is connected to the water inlet 5 of the second mating surface through another water channel 6 arranged in a spiral shape in the circumferential direction.

According to a more preferred embodiment of the present invention, as shown in Figure 1, the filler monomer 1 is in the shape of a ring, and the filler monomer 1 includes at least two water channels 6, and each water channel surrounds a 1/2 annular filler unit. Body 1, in the specific process, the cooling water flows into the packing monomer 1 through the water inlet hole 2 of the first mating surface, makes a semicircular circumferential spiral movement in the packing monomer, and then flows out from the water outlet hole 3 of the second mating surface , into the next filler unit 1, a waterway is provided at the end of the group of filler unit 1, water is introduced into the water inlet 5 of the second mating surface, cooling water flows out from the water outlet 4 of the first mating surface through the waterway 6, and the water cooling cycle is completed process.

According to a more preferred embodiment of the fundamental invention, as shown in Figure 2, the cooperation between the filler monomers is the first matching water inlet 2 of the second filler monomer and the second matching surface of the first filler monomer. The water port 3 is connected, and the connection method is to penetrate the hole of the tie rod through the tie rod and connect them.
