Abstract
The utility model relates to a novel long-service life sealing part for a ceramic plunger pump, which belongs to the technical field of ceramic plunger pump and mechanical sealing part manufacturing,and is mainly technically characterized in that one surface of a seal ring is in a plane structure and is connected with a guide ring; the other surface of the seal ring is provided with a circular groove; and a framework support ring is inlaid in the circular groove between the seal rings. The upper part of the framework guiding support ring is provided with circular ridges, is mutually inlaid and connected with the seal ring. The action of a ceramic plunger which is produced in motion and deviates form the axis is calibrated and compensated at any time, thereby reducing the friction betweenthe plunger and the sealing part; and the sealing effect is ensured by regularly adjusting the gap between the sealing part and the plunger. The novel long-service life sealing part for the ceramic plunger pump has the advantages of simple structure, low manufacturing cost, long service life of the sealing part, less raw material, more than three times longer service life compared with the traditional stacked or overall sealing structure, and good enterprise and social benefits.
Description
One, technical field
The seal arrangement that the utility model relates to a kind of ceramic plunger pump or mechanically uses, specifically a kind of ceramic plunger pump belongs to pottery and machinery and uses air locking manufacturing technology field with novel extended life seal device.
Two, background technique
The used air locking structure of current ceramic plunger pump all adopts folded formula or monolithic construction to seal basically, the seal ring of this structure does not have regulatory function in design, can not guarantee that plunger moves always on center line, air locking and ceramic plunger easily wear and tear, can not compensate after the wearing and tearing, working life is short especially, the manufacture cost height, influence ordinary production because of often changing air locking, often dismantle repeatedly and also can produce harmful effect the pump housing and ceramic plunger and mechanical part, therefore, seek a kind of novel extended life seal device of exploitation to improving the ceramic product quality, prolong the working life of air locking, reduce cost of goods manufactured, have very high use value.
Three, model utility content
The purpose of this utility model is exactly to be folded formula or integrated sealing structure in order to solve existing seal ring, be difficult to guarantee that plunger moves always on center line, because structure is limit, the center of each seal element is difficult to point-blank, and manufacture cost height, working life is very short, thereby proposes a kind of new technological scheme.
For achieving the above object, the utility model can be realized by following scheme:
The ceramic plunger pump is with novel extended life seal device, it is to be provided with by two ends to be provided with seal ring in the middle of the guide ring and overlaid constitutes, the one side of seal ring is that plane structure and contact with guide ring is connected, the another side of seal ring is provided with annular groove, and mosaic set is provided with the skeleton support ring on annular groove between seal ring and the seal ring and plane.
One end is provided with guide ring, the other end is provided with skeleton guiding support ring, the centre is provided with seal ring, and overlaid constitutes, described skeleton guiding support ring one end face is provided with the annular ridge concentric with it, and what the annular ridge above the skeleton guiding support ring was provided with above with seal ring is connected with its concentric annular groove mosaic set; The annular groove and the seal ring that are located at the seal ring one side are concentric structure, and guide ring and seal ring, skeleton support ring, skeleton guiding support ring are concentric circle.
The advantage that the utility model had is: simple in structure, cheap for manufacturing cost, mosaic set is provided with the skeleton support ring between seal ring and seal ring, can make the air locking longer service life, also save raw material, traditional folded formula or integral seal device, generally be at 20kg/cm its working life on the ceramic plunger pump
2Can only use under the pressure 30～50 days, and the most only have 15 days.After adopting the utility model extended life seal coil structures, through production testing and use, at 80kg/cm
2Can use 6 months under the pressure, withstand voltage higher, and increased substantially working life of ceramic plunger pump, can be society and manufacturing industry and brought good economic benefit.
Four, description of drawings
Accompanying drawing 1 is a kind of example structure schematic representation of the utility model;
Accompanying drawing 2 is that the A-A of the utility model accompanying drawing 1 is to the sectional structure schematic representation;
Accompanying drawing 3 is the another kind of embodiment's sectional structure of the utility model schematic representation;
Accompanying drawing 4 is the utility model accompanying drawing 2 use sectional structure schematic representation on the ceramic plunger pump.
Five, embodiment
With specific embodiment the utility model is described in further details in conjunction with the accompanying drawings now:
Embodiment one:
A kind of ceramic plunger pump is with novel extended life seal device, and the upper end is provided with guide ring 1, and the lower end is provided with skeleton guiding support ring 4, is provided with annular ridge above the skeleton guiding support ring 4.Between guide ring 1 and skeleton guiding support ring 4, be provided with two seal rings 2, the lower end surface of two seal rings 2 is respectively equipped with annular groove, mosaic set is provided with skeleton support ring 3 between seal ring 2 and seal ring, and a Transverse plane of skeleton support ring 3 is practised physiognomy to contact with the plane of seal ring and is connected.Skeleton guiding support ring 4 is connected with the annular groove mosaic set by annular ridge with seal ring.Guide ring 1 and seal ring 2, skeleton support ring 3, skeleton guiding support ring 4 are concentric circle.
Embodiment two:
A kind of ceramic plunger pump is with novel extended life seal device, upper and lower end is provided with guide ring 1, between guide ring 1 and guide ring, be provided with two seal rings 2, the corresponding face of two seal rings 2 is respectively equipped with annular groove, mosaic set is provided with skeleton support ring 3 on the annular groove between seal ring 2 and the seal ring, the outside plane structure of skeleton support ring 3, inner side surface are arcuate structure.
The ceramic plunger pump is with novel extended life seal device, it is the structure that seal designs is become to have guiding, the disalignment action that cantilevered ceramic plunger produces when moving up and down is had the pilot seal part at any time and proofreaies and correct and compensate, guaranteed that ceramic plunger moves up and down at the center all the time, reduced the friction of plunger and seal, gap by regular adjustment Sealing and plunger guarantees sealing effect, has prolonged the life-span of air locking greatly.
The disalignment action that produces during the ceramic plunger motion is corrected at any time and compensates, and reduces the friction of plunger and seal, and the gap assurance sealing effect by regular adjustment air locking and plunger increases the service life.Diameter range 85～the 500mm of sealing configuration.Be suitable for most the ceramic plunger pump that sealing configuration is used for diameter 85～500mm scope.
