Description
Technical field
The utility model relates to the hydraulic applied technical fields of pumping plant, especially a kind of to be used for coal mine fully-mechanized mining working emulsion
The novel plunger piston sealed structure of pump, atomizing pump and water injecting pump.
Background technique
Currently, reciprocating plunger pump, in order to guarantee plunger in reciprocatory movement, lubricating oil inside crankcase not with
Plunger outflow, it is common to use woven compo is as sealing material, i.e. packing.
Packing usually has fixed specification in purchase, in use, being cut into corresponding length according to demand, is then pressed into advance
Fixed shape is needed when assembly to be inserted according to opening direction together to install, and to be added gasket in each packing, is grasped
Make complicated.
In use, it needs personnel to check at each class and compresses screw plug, in replacement, need steel bushing component is whole
Body could be replaced after removing.Simultaneously because maintenance personnel can not operate in maintenance fully according to design requirement, the packing longevity is caused
Life shortens.
Utility model content
The applicant provides a kind of novel plunger piston sealed structure, to replace for the disadvantage in above-mentioned existing production technology
For original multiple tracks packing, the seal form of gasket combination, facilitates installation, maintenance, improve service life.
Technical solution used by the utility model is as follows:
A kind of novel plunger piston sealed structure, including high pressure cylinder sleeve, the high pressure cylinder sleeve middle part are provided with stepped hole, the step
The step surface in hole goes out to be equipped with spring base, holddown spring is provided in the spring base, one side of the spring base is equipped with close
The outer end face of sealing assembly, the seal assembly is concordant with the outer end face of high pressure cylinder sleeve;Plunger is inserted at the middle part of the high pressure cylinder sleeve,
The outer circumference surface of the plunger and the inner peripheral surface of seal assembly are fitted close, and also pass through spiral shell at the outer end face of the high pressure cylinder sleeve
Nail installation pressing plate.
Its further technical solution is:
The seal assembly is integral type cirque structure, and middle part is three sections of woven fibre material plastic hoops, the volume
The left end of textured fiber material plastic ring is stop collar, and right end is guide ring, and protrusion is arranged in the outer end face of the stop collar, described convex
It rises and is clamped with pressing plate cooperation, the outer end face of the guide ring is abutted with spring base.
The beneficial effects of the utility model are as follows:
The utility model is compact-sized, reasonable, easy to operate, and metal guide ring, stop collar and woven fibre material are done
Integrally, it is compressed by spring, when installing with replacement, it is no longer necessary to insert together, substantially increase the effect of assembly
Rate reduces operating technology threshold.
Meanwhile by spring pre-pressing, with the abrasion of fibrous material in use, pressing force can mend it
It repays, so that sealing is effective always, reduces the work of daily maintenance personnel, improve work efficiency.
Meanwhile the adverse effect of human factor is reduced in this way, improve the service life of plunger sealing.

Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As depicted in figs. 1 and 2, the novel plunger piston sealed structure of the present embodiment, including high pressure cylinder sleeve 7,7 middle part of high pressure cylinder sleeve
It is provided with stepped hole, the step surface of stepped hole goes out to be equipped with spring base 5, it is provided with holddown spring 6 in spring base 5, the one of spring base 5
Side is equipped with seal assembly 4, and the outer end face of seal assembly 4 is concordant with the outer end face of high pressure cylinder sleeve 7;It inserts at the middle part of high pressure cylinder sleeve 7
Enter plunger 1, the outer circumference surface of plunger 1 and the inner peripheral surface of seal assembly 4 are fitted close, also logical at the outer end face of high pressure cylinder sleeve 7
It crosses screw 2 and pressing plate 3 is installed.
Seal assembly 4 is integral type cirque structure, and middle part is three sections of woven fibre material plastic hoops 402, and braiding is fine
The left end for tieing up material plastic ring 402 is stop collar 401, and right end is guide ring 403, and protrusion is arranged in the outer end face of stop collar 401, convex
It rises and is clamped with the cooperation of pressing plate 3, the outer end face of guide ring 403 is abutted with spring base 5.In actual installation process, as follows
It completes:
Step 1: holddown spring 6 is integrally formed in spring base 5;
Step 2: be packed into integrated holddown spring 6 and spring base 5 is already assembled as in the stepped hole of high pressure cylinder sleeve 7, and
Clamping;
Step 3: seal assembly 4 is pressed into the stepped hole of high pressure cylinder sleeve 7, and abutted with holddown spring 6 and spring base 5;This
When, the end face of seal assembly 4 is concordant with the end face of high pressure cylinder sleeve 7;
Step 4: installation pressing plate 3,3 inside of pressing plate is contacted with the end face of high pressure cylinder sleeve 7 and seal assembly 4 simultaneously, and is screwed on
Screw 2 (note: screw 2 is only screwed at this time, is not locked);
Step 5: insertion plunger 1, lock-screw 2.
Step 6: remaining parts are sequentially packed into, last pressing plate 3 is fixed with screw 2 and spring washer.
It manually being loaded when the original plunger sealing installation of the utility model effective solution, inefficiency, technical threshold is high,
And sealing element is integrally formed by problem complicated for operation by new technology, simplifies installation steps, while using internal bullet
The form of spring pre-pressing, improves work efficiency.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is within the protection scope of the utility model referring to claim, can make any type of modification.
